The Flight of Sandhill Cranes and Graduate Students

by Bob Kemerait


As the end of the spring semes-
ter approaches and the temperature and
humidity make it feel more like August
than April, I begin to look to the promise
of autumn. Fall brings with it the hopes
and enthusiasm of thousands of new
students and a new school year. Fall
means the start of football season and
Saturday afternoons spent at Florida
Field. And fall marks the return of the
beloved sandhill cranes to Paine's Prairie,
Orange Lake, and to fields, pastures, and
marshes around our county. I am filled
with a deep satisfaction when I hear the
first flock as it passes overhead; they fly
so high that you usually cannot spot
them until your eyes are guided to the
formation by their throaty, rolling calls.
They are welcomed back for as long as
they will stay. Their journey has brought
them from as far away as Canada, and
one can only wonder at the difficulties
they have endured. Storms, scarcity of
food, and loss of safe havens due to ur-
ban sprawl have surely followed them
along their route. I like to believe that
there is a special bond among the dozen
or so cranes that make up these migrat-
ing flocks; a bond that has been forged
by shared trials and the need for com-
panionship to reach their destination.


The birds probably could not have made
the trip alone, but together they have
traveled thousands of miles safely.
The cranes spend the winter in
our county, foraging for food, feeding in
large groups, and seemingly enjoying the
time spent together. And then with the
advent of spring, they hear some distant
call and begin to gather in preparation for
their departure. They do not leave all at
once, but they slowly precipitate back
into groups for the journey home. You
can watch as a few individuals spiral ever
higher into the blue sky all the while
calling for others to join them and the
safety that their number provides. When
the flock reaches some critical mass, the
long return trip begins. However, ac-
cording to local ornithologists, a small
population of cranes remains year-round
in Alachua County. On a recent trip to
Orange Lake with Dr. Kucharek to visit
a field trial, I heard the lone call of a
sandhill crane from somewhere in the
marsh. No one can know why this one
was left behind, but in my imagination I
feel that it must not have been able to
answer the urgent calls of its departing
brethren. Like the songs of the sirens in
Greek mythology, the cries from each
succeeding flock must have been tortu-
ous to those that stayed. Sadness must
follow when the calls fade into the dis-
tance.
This spring and summer, a
group of exceptional students will gradu-


ate and leave our department, as will a
faculty member whose commitment to
science and teaching has been an impor-
tant part of our education. It is no secret
that the community we share as students
is temporary and that one day (hopefully)
we will all finish and move on to new
challenges throughout the world. The
names of graduates from an earlier time,
such as Gitaitis, Ploetz, Young, Batche-
lor, Marois, Olexa, and many others are
still mentioned by long-time faculty and
staff. They have become the stuff of
legend for current students. As a fledg-
ling graduate student, I watched with
interest as the "seniors", such as Tony St.
Hill, Rose Koenig, Gustavo Mora, Bin
Yan, Li-Tzu Li, and Ruhui Li graduated
and left over time. I admired them, but
their careers were so far ahead of mine
that their graduation did not affect me
directly. Others, such as Manjunath
Keremane, Yong Ping Duan and Vicente
Febres, remained as post-docs so that the
necessity of their departure was post-
poned.
The graduations this spring and
summer are different. When students
begin this program, they are strangers in
the department and their knowledge of
plant pathology may be limited. I was
fortunate to start in the fall of 1994 and
was immediately surrounded by those
who would share similar courses, con-
cerns, and difficulties. During the period
of 1994-1996, we formed a very close

group because of shared experiences and
education in the department. We learned
to work together, study together, and
trust each other as we struggled to begin
our research. We grew to depend on
each other for help and also enjoyed pic-
nics, parties, meetings and selling mush-
rooms together. There was never any
question that someday we would leave,
but our graduate experience had always
been shared with this group. The group
became as familiar as the walls and class-
rooms of Fifield Hall.
And then the graduations began.
Tso-Chi Yang finished in what seemed
to be an impossibly short period of time.
His graduation was followed quickly by
those of Tim Widmer, Tammy Plyler,
Jugah Kadir, and Erin Rosskopf. I was
not sure that the department as I had
come to know it would survive with
Erin's graduation. These students were
close friends to us so that their depar-
tures were mixed with both excitement
and sadness. The ranks were thinned,
but a core group remained that was ever
supplemented by new students and
friends. Next it was Carlos Forcellini's
turn to finish. Many of us had watched
Carlos's son Bernardo grow and felt close
to his family. Carlos was the voice of
calm and reason during even the most
difficult situations. Soon after Carlos
left, Kenny Seebold graduated. For four
years Kenny and I had shared an advisor,
a lab, an office, and even a departmental
mailbox. We shared a house for the final
two years of his tour in the department.
I miss his humor and companionship
even today.
Now so many are graduating
that most of those who helped me
through the early years will be gone. The
"family" that shared in graduate life will
be scattered. Gustavo Astua-Monge,
Simone Tudor-Nelson, Patricia De Sa',
Yinong Han, "Texas Bob Harveson,
Daniela Lopes, Dauri Tessmann, Xio-
mara Sinisterra, Adriana Castafieda and
Chandra, will all be leaving. Only
brother Bayram will remain and soon he


too will be gone. I know how the cranes
that watch as the others take to flight
must feel. It is not so much a regret that
I must stay, because I am excited to con-
tinue my work and there are many new
friends in the department now. No, the
sadness is the realization that I cannot go
with these classmates, and that this marks
the end of a special part of our lives.
As a student, I anticipated
learning much about the science of plant
pathology. I have also learned many
things beyond disease progress curves,
life-cycles of fungi, and systemic acquired
resistance. I have learned that although
we began this journey alone, we did not
walk it by ourselves. We have been ac-
companied by special friends and class-
mates who struggled with us. I have
learned that the best solutions to prob-
lems often come from a group of people
with different ideas, backgrounds, and
temperaments who work together. I
have learned that doing research is much
more exciting when you can share your
small victories with a colleague, and
much less daunting when you can share a
setback with a friend. And finally, I have
learned that despite the problems and
strife that can develop and fester within a
larger group or institution, the bonds of
friendship that are formed during these
same times make it all worthwhile. To
those who are ready to depart now, both
Dr. Kistler and the students, we in the
Plant Pathology department are grateful
for the times that you have shared with
us. We wish you godspeed to your new
homes and success in your careers. And
like the sandhill cranes that return each
fall, as long as we are here in Gainesville
you will have a home to which you can
return also.

Traveling scientists:
*Dr. R. Charudattan traveled to Ral-
eigh, N.C. to present an invited talk enti-
fled, "Current Status of Biological Con-
trol of Weeds" at an international confer-


ence, "Emerging Technologies for Inte-
grated Pest Management: Concepts, Re-
search, and Implementation." The Con-
ference was organized by the College of
Agricultural and Life Sciences, North
Carolina State University, and sponsored
by USDA-CSREES-Pest Management
Program, NSF center for IPM, APS,
Entomological Society of America, and
others. The meeting was attended by
about 250 scientists and representatives
from universities, industries, govem-
mental agencies and nongovernmental
organizations (NGO's) of the United
States and a few other countries. There
were several excellent reviews of cutting
edge pest control technologies. The con-
ference provided a good overview of
IPM efforts during the past two decades
along with the perspectives of industrial,
governmental and NGO scientists. The
APS press will publish the proceedings
of the conference. The information about
this conference can be found at the web
address
http://ipmwww.nscu.edu/impconferenc
e
*Dr. R. Charudattan also visited
Vicosa, Brazil in route to the Federal
University of Vicosa, Minas Gerais, to
participate in Mr. Alan Pomella's Ph.D.
defense. Many of you may remember
that Alan did part of his Ph.D. research
in Dr. Charudattan's lab and that he is
the co-Chairman of his research com-
mittee. Dr. Charu said that he was chal-
lenged by participating in this event be-
cause Alan's dissertation and exam were
in Portuguese. Dr. Charu could under-
stand the basis of Alan's work, but the
details of the discussion section were a
little hazy. Dr. Charu was thankful that
some of the committee members asked
questions in English. Alan passed his
exam and celebrated afterward with
BBQ.

Undergraduate student's trip:
Several undergraduate students of our
department went to the Apopka Re-
search Center for a tour, this month.


They also traveled to a state of the art
ornamental nursery nearby.
Wedding:
Congratulations to Winnette and her
husband, Jerone. They were married on
Saturday April 24th at 5 o'clock at the
Faith Tabernacle of Praise Church in
Gainesville. The reception was held at
the Westside Recreation Center right
after the ceremony. Once again, con-
gratulations and we wish you and your
husband the very best in your marriage
together.

Qualifying exams:
Our good friend Bob Kemerait success-
fully completed his qualifying examina-
tions.
Congratulations, Bob!!

Special seminar


.."i' ,I ,


in


our department

As we all know, Dr. Patricia
Zambryski has accepted our invitation to
present a seminar in our department on
May 18. We asked Dr. Zambryski to
write a summary of her talk for our
newsletter, and she kindly did that. Here
it is a sample of what she will discuss in
this special seminar.


Viral and developmental clues into
plasmodesmata function

P. Zambyski, Det. of Plant and Microbia
Biology, Koshland Hall, University of Caifor-
nia, Berkeley, CA 94720

We approach the study of plas-
modesmata (PD) by monitoring their
function following two general types of
provocation, either following infection
with plant viruses, or following alteration
in developmental programming.
Regarding plant viruses, we con-
tinue to use tobacco mosaic virus (TMV)
as a molecular probe for PD function. In
particular, we have focused on the
movement protein (MP) of TMV. To
date we have mapped 5 regions of the 30
kDa TMV-MP, C-terminal domains A
and B define single strand nucleic acid
binding activity, domain C is essential for
proper folding domain D at the very end
of TMV-MP contains sites for phospho-
rylation by a plant cell wall associated
protein kinase, and domain E specifies
gating of PD. Our most recent work
delimits a 6th domain, F, for cytoskeletal
binding. We have initiated studies on the
MPs of turnip crinkle virus (TCV). This
virus is of particular interest since it in-
fects Arabidopsis, providing a genetically
tractable host system to dissect PD
structure and function. In addition, TCV
encodes 2 very small MPs, p8 (8 kDa)
and p9 (9 kDa), that may provide a more
precise localization of signal sequences
for intra- and intercellular movement.
Regarding PD function during de-
velopment, we have begun to address
changes in PD function in the shoot apex
of Arabidopsis. The availability of fluores-
cent markers that monitor symplastic
movement, such as HPTS (8-
hydroxypyrene- 1,3,6 trisulfonic acid)
makes these types of studies highly feasi-
ble. HPTS is loaded into the phloem and
distributes symplastically to sites far from
the site of initial loading. The fluorescent
tracer is monitored by confocal imaging.


We are particularly interested in deter-
mining symplastic domains in the shoot
apical meristem during development. We
have observed that the patterns of dye
movement in the vegetative meristem
becomes altered during the transition to
flowering. Much research in the area of
floral development has focused on the
induction of genes, particularly transcrip-
tion factors, essential for reprogramming
the meristem to produce inflorescence
and floral meristems. However, our
studies suggest that intercellular traffick-
ing via PD within the meristem also un-
dergoes changes when flowering is in-
duced.
An additional area of research in-
volves our attempts to identify PD com-
ponents by a genetic screen for mutations
in Arabidopsis with altered PD trafficking
patters/size exclusion limits. For these
studies we are screening embryo lethal
mutants for embryos with altered PD
size exclusion limits. One mutant ise-1
(Increased Size Exclusion limit-1) allows
11 kDa dextrans to move from cell to
cell, while wild type embryos generally
have a size exclusion limit below 3 kDa.
The ise-1 mutant also exhibits morpho-
logical defects late in embryogenesis.

cation in flowering plants. The

Who is Who in our Department


Who QS "i ..'



Dr. Kenneth Pernezny's Lab -
Everglades Research Center,
Belle Glade

The ERC, Everglade's Research
and Education Center, is located in Belle
Glade, Florida-the geographic hub of
some of the most intensive vegetable
production east of the Mississippi. Plant
pathological research at the center is fo-
cused on the development of effective,
low-input disease management programs.
Dr. Pemezny's lab, which focuses on
integrated pest management on vegeta-
bles and research on bacterial diseases, is
the highlight of this month's Who's
Who.
Dr. Kenneth L. Pernezny
came into plant irli...._-- through the
back door. After earning his B.Sc. at
Penn State, he spent five years teaching
chemistry at a high school in Pennsylva-
nia. Since he couldn't seem to get people
to understand what a mole was (besides a
furry little animal), he decided it was time
to move on and melded his two interests,
microbiology and botany, into a career in
plant pathology. He received his M.A. at
Lehigh University and his Ph.D. at Ohio
State and is now working 60" ,, extension
and 4, .. research at the ERC. His major
projects right now involve varietal and
seed treatments for bacterial spot of let-
tuce, Xanthomonas campestris pv.vitians.
Dr. Pemezny's lab is also working with
bacterial spot of pepper, including copper
tolerance and race profiles. His lab has
completed and is selling the Florida To-
mato Scouting Manual (be sure to pick
up a copy!) and is in the process of pro-
ducing a set of flash cards on diseases of
tomato and pepper with
Dr. Kucharek. In the fall,
Dr. Pemezny plans to
work with Dr. Lawrence
Datnoff on biological
control of Fusarium


crown rot of tomato.

Dr. Pemezny isn't all work
though-he plays drums in a Christian
musical ensemble and he's a certified
regional soccer refe-
ree. He also admits I .
n nlno lonts" of I


tennis with his fam-
ily.

Janice Long Collins received
her Bachelor's degree in Education from
the University of Florida. She is thinking
about getting her Master's in Information
Technology and is currently a biological
scientist in Dr. Pemezny's lab. She enjoys
the variety in her work-from being in
the lab doing microbiological work, to
planning a presentation on the computer,
to record-keeping, to working in the
greenhouse or farmer's field in South
Florida. Every day is a little different.

Outside of work, Janice is in-
volved in her church (as a member,
teacher and part of the
choir!) and she is on the
School Advisory Com-
mittee at Cypress Trails
Elementary and the Education Advisory
Board in Royal Palm Beach. This allows
her to shape the educational experiences
of her children, which she is very excited
about. Janice is also involved in soccer
through her son Zack and always ends
up being team mom, which she enjoys.
She also sews and does most any kind of
needlework in her spare time.

Myrine B. Graham Hewitt is
the senior lab technician in plant pathol-
ogy in Dr. Pemezny's lab. She has four
children who are all grown and living on
their own with three married. Most of
her spare time is occupied with church
work. She visits sick and missing mem-
bers, is church clerk and church leader, a
Sabbath school teacher, and the
Women's Ministry leader. Outside of
work, she also enjoys a itJd.i;i, cooking

and sewing. She spends time with her
children and grandchildren and likes to
see the looks on people's faces when she
plays tricks on them!

Did you know that...

SDr. Pemezny says "there's nothing like
running up and down the field with a
bunch of 14-year-olds to find your aero-
bic limits" in reference to his soccer ex-
periences!
Dr. Pemezny once considered organic
chemistry for his Ph.D. but gave up
when all he created in his organic labs
was black tar!
Janice is a voracious reader of all types
of books. She has four children and is
married to a firefighter!
Janice also has a small zoo (besides the
four children!) of a collie, a Miniature
Pinscher, 4 cats, some fish and a parrot!
Myrine has seven grandchildren and
her youngest child is doing missionary
work in Korea!
SMyrine also has a hobby of picking up
pennies!


Visiting scientists
and post-docs

Slobodanka Grsic-Rausch
was bom and raised in Novi Sad, Yugo-
slavia. Danka also earned both her B.Sc.
and M.Sc. degrees at the Faculty of Biol-
ogy College at Novi Sad University. Her
bachelor's is in natural sciences with an
emphasis on biology, while her master's
was an investigation of the in vitro propa-
gation of the apical meristem of hops.
There was a need in her country to pro-
duce virus-free hop plants as viral infec-
tion both reduces plant yield and affects
the plants' production of an alpha-acid, a
necessary component in the taste of beer.
Danka earned her Ph.D. at
Johan Wolfgang Goethe University in
Frankfurt/M (West) Germany. For her
dissertation, she investigated clubroot
disease in crucifers and the role of auxins


in clubroot development. (Incidentally,
she met Thomas (Dr. Rausch) during her
Ph.D. work). After her Ph.D., Danka
did a post-doc at the same university in a
neighboring lab working on carotenoid
biosynthesis. Currently, Danka is a vis-
iting scientist in Dr. Prem Chourey's lab
trying to clone the invertase inhibitor
from maize. When Danka returns to
Germany, Thomas hopes to have her
work in his lab, but she is not sure.
When Danka is not working in
the lab, (and believe me, it's a rare occa-
sion, because I've ridden my bike back to
work many late nights and she hadn't left
yet), she enjoys a few hobbies. Danka
enjoys dancing (any type), growing flow-
ers, and "balcony" gardening. She also
likes to preparing exotic meals from dif-
ferent countries in which the arrange-
ment of food is just as important as the
taste. Danka also reads for at least five
minutes before falling asleep every night.
She particularly enjoys non-fictional, psy-
chological and philosophical literature.
She is currently reading The Zen of the Art
of Motorycle Maintenance by Pirsing.
Danka said that she would also like to
mention how much she is enjoying her
time here in Florida. She said that the
people here are so friendly and nice and
that she loves the fact that she has met so
many people from so many different
countries here. She also loves the
weather (I told her that she has never
experienced a Florida summer!) I know
that she is enjoying herself, but I can tell
that she is missing Thomas ever since he
has returned to Germany.

Best wishes to you Danka;
it's good to have you here!!
