Meet... The Syvertsen Lab
Dr. Jim Syvertsen's Lab focuses on physiological
responses of citrus to the environment

by Meredith Jean Morton Photos by Gretchen Baut
Dr. Jim Syvertsen's lab studies the effects of environmental stress on
the physiological responses of citrus trees, including growth, yield, water
relations, photosynthesis, carbohydrate balance and mineral nutrition.
Some common environmental stresses are high temperature, salinity, I
drought, flooding and insect pressures. Research is also being conducted
on environmental effects on fruit shape, particularly 'sheep-nosing.'
Sheep-nosing is a fruit elongation caused by high temperatures and .
vigorous growth, especially in grapefruit.
The lab is very international and includes scientists from China, Left to right: Dr. Kuo TanLi, Baylis Carnes, Jill Dunlop, Dr.
Taiwan, Spain, California and Florida. Slightly crowded, with eight people Jim Syvertsen, Dr. Hong Li, Juan Gabriel Peres, Dr. Paco
working together daily, Dr. Syvertsen's lab covers many aspects of plant Garcia-Sanchez and Eva Ros-Ruiz.
physiology.
"We're all one team," Dr. Syvertsen said. "We work great together."
Jill Dunlop described the lab as the 'most down-to-earth lab' dealing with physiological aspects of plant growth and production. Investigators
in Dr. Syvertsen's lab frequently collaborate with other scientists at CREC on research projects.
Dunlop said that although the lab tests effects of stress on plants, the members of Dr. Syvertsen's team experience little stress in the lab.
"We don't have a lot of stress," she said laughing. "The plants don't talk back."


Dr. Jim Syvertsen
has been working for UF
since 1978, after he
received his Ph.D. in
plant ecology from New 4r /
Mexico State University.
His research interests are
photosynthesis and
carbohydrate balance in "
citrus. In his free time,
Dr. Syvertsen enjoys
sailing on his Hobie Cat, and said he 'has
played a lot of tennis.' He also spends time
'looking after his wife,' although he said 'she
would say that she looks after me.' Dr.
Syvertsen is a native of Oxnard, California,
about 60 miles northwest of Los Angeles
and a town with a rich history in citrus and
agriculture. He chose to stay in school to
earn his Ph.D. because he picked lemons
while in grade school in California and
realized he wanted to accomplish more in
life.

What is Plant Stress Physiology?
Plant stress physiology is the study of how
plant growth and production are affected
by environmental stresses. Simply, these
stresses are any natural situation which
may cause an altered state to the plant.
Some environmental stresses are drought,
heat, cold, salinity, mineral deficiency,
mineral toxicity, oxidative stress and water
logging. Each of these stresses could
potentially impact the growth and
production of a plant.


Jill Dunlop (near il i.. V
,I right) is self-de-
scribed as 'Dr. C
Syvertsen's right-
hand man.' Jill
graduated from
Elon College in
North Carolina with
a B.S. in Environ-
mental Studies and
has been working forDr. Syvertsenat
CREC for over three years. She sets up and
manages experiments, and obtains and ana-
lyzes data. The Clearwater native is married
to Jeff Dunlop, and is the mother of two-
year-old Annabelle. Jill enjoys golfing and
cooking, and said she loves food, with a
weakness for 'all foods that are bad for you.'
Dr. Hong Li (above right) has a Ph.D. in
soil science from Laval University in Quebec
City, Canada, and is Dr. Syvertsen's research
assistant. Dr. Li is from Guangdong, China
and has been with UF for two years. She
works with Dr. Syvertsen on greenhouse and
field studies on the effects of root weevils,
soil flooding and soil type on citrus growth.
She has been working in soil research for
about 24 years, and is most proud of
publications in the Florida State Horticultural
Society Proceedings and the Journal of Soil
Science. She likes to watch TV news at night
to 'know what is happening in the world'
and also enjoys watching tennis. Dr. Li is
married and has two daughters, Annie, 15,
and Sylvie, 12.

Dr. Kuo-Tan Li is a post-doctoral associate
and native of Taiwan. A graduate of Cornell
University, Kuo-Tan has been at CREC
since December 2003 and will stay from one
to two more years. At Cornell, Kuo-Tan

of mechanical harvesting on citrus tree
health and production since he's been at
CREC. Kuo-Tanlikes swimming and snow
skiing, although he lamented that he hasn't
had a chance to snow ski since he's been in
Florida. Traveling is another of Kuo-Tan's
favorite pastimes, especially traveling
somewhere with a cold, dry climate, "'with
snow for skiing."

Baylis Carnes is a 2003 graduate of
Winter Haven High School and has been
working in an OPS position for Dr. Syvertsen
for a year and a half. Since Baylis began
working inthe lab, he fertilizes plants, helps
the post-docs, collects data and organizes
the lab. Baylis is attending Polk Community
College to pursue a degree in Business
Administration. An avid outdoorsman, he
enjoys fishing and hunting in his free time.
Baylis said he likes working in Dr.
Syvertsen's lab because he has been
exposed to a variety of cultures from the
lab's international diversity.

Eva Ros-Ruiz is also from Cartagena,
Spain, and has been working in an OPS
position in Dr. Syvertsen's and Dr. Jackie
Burns' lab for one year and five months.
Eva studied law at the University in Spain,
but said after her husband, Paco came to
the U.S. to work, she wanted to come, too.
The most interesting thing Eva said she
has learned since working at CREC was
learning to prepare gels in Dr. Bums' lab.
In her free time, she enjoys reading books,
listening to music and going to see movies

He is also studying elevated CO2 and
drought effects. Paco came to CREC in 2000
as part of a six-month program for Ph.D.
students, the same program currently
sponsoring Juan Gabriel Perez. In his free
time, Paco plays soccer for the CREC team
and likes to read. He would like to travel to
other states during his time here, since he
has only seen Florida. He is married to Eva
who also works in Dr. Syvertsen's lab.

CTV in Dominica
by Meredith Jean Morton
Alab technician's visit to CREC may help
slow or prevent the decline of the citrus
industry on the small Caribbean island of
Dominica.
Naomi Commodore, a lab technician for
the plant protection and quarantine services
of the Dominica Ministry of Agriculture,
visited CREC May 11-13, to learn detection
techniques for the citrus tristeza virus. The
virus, transmitted by the brown citrus aphid,
has caused nearly a total loss of trees from
sour orange root stock in the southern part
of Dominica, Commodore said.
Commodore traveled to Florida as a
follow-up to a March 14-25 trip to Dominica
taken by CREC plant pathologist Dr. Ron
Brlansky, as part of a cooperative effort
between UF/IFAS and Dominica scientists
to detect migrating citrus diseases and to
prepare defenses against them.
While in Dominica, Dr. Brlansky and
Debbie Howd examined strains of citrus
tristeza virus present in the Caribbean.
Commodore visited CREC to receive training
in virus detection techniques from Dr.
Brlansky to determine the spread of citrus
tristeza virus over the island.
Dr. Brlansky taught Commodore the

Dr. Curt Colburn
by Meredith Jean Morton

Congratulations to Dr. Curt Colburn,
who received his Ph.D. in plant pathology
onApril 30, after working on his degree at
CREC with Dr. Jim Graham and Dr. Kuang-
Ren Chung.
Dr. Colburn, who has been at CREC
since January 2002, researched
Phytophthora root rot of citrus. He said
they were looking for a potential biological
control for Phytophthora, a serious plant
pathogen with a huge host range.
Phytophthora can kill young trees in
the nursery and newly established groves
in orchards. It also causes brown rot of
the fruit and severe root damage when
present long term.
Dr. Colburn said he chose Florida for
his Ph.D. to gain a different experience from

Phytophthora Is Not a Fungus?
*Phytophthora, derived from Greek, means
plant (phyto) destroyer (phthora). It is a
microscopic, soil-borne parasitic
microorganism that causes root rot of a
wide number of plant species, including
many native and introduced ornamentals
and crops. In Florida, P. nicotianae and
P. palmivora cause serious and
economically important diseases of
citrus.

* Once considered a fungus, biologists now
classify Phytophthora as a water mold
(Oomycetes) and a member of the

"My short term goal is to get a 2-year
post-doc to earn more experience and

tissue blot and the enzyme-linked
immunosorbent assay (ELISA) techniques
for detection.
"We are hoping to control the host trees
infected with the virus," said Commodore,
who has been working on the project for
about a year. "Identifying trees already
infected will [help us devise strategies to]
decrease the spread of the aphid."
After identifying and eliminating trees
infected with the citrus tristeza virus,
Dominica will adopt the use of new citrus
rootstocks not susceptible to quick decline.
Dominica currently uses sour orange
rootstock which is susceptible to quick
decline.
"The virus is new to us and no one on
the island has training to combat it,"
Commodore said. No%\ I have learned
techniques to go back and do surveys, so
we can eliminate the virus."

Photo Corner
The PhotoLab is setting up a new
Epson 44" wide printer. The Photolab
also has a Hewlett Packard 36"-wide
printer, so we now have two options
for poster printing. Call GretchenBaut
(Ext. 1270) to book appointments for
poster printing. The printers get busy
for summer meetings.
An easy way to protect your posters
is to spray them with spray lacquer.
One or two light coats provides some
protection against water stains and
could avert a poster disaster, especially
while traveling. And, if traveling by
air, check ahead. Some airlines do not
allow poster tubes/cases above a
certain size as carry-ons.

Girl Scouts
Girl Scout Troop 329 from Winter
Haven participated in an orienteering
activity on May 1 at the Rock Springs
Run State Reserve. Orienteering
involves navigating an outdoor route
using a map and compass. Teams (or
individuals) must find designated
points and complete the route in the
shortest amount of time to win. Troop
329 had two teams that did two courses
each. Troop leader Shelley Jones (from
Dr. Braddock's lab) said that one of their
teams beat a Boy Scout troop! The
event was sponsored by the Florida
Orienteering Association. The girls
thank Gretchen Baut for the maps.
Visit www.floridaorineteering.org for
more information on this popular
outdoor sport.


The Florida Museum of Natural History
on the UF Gainesville campus will open
its McGuire Center for Lepidoptera and
Environmental Research on Aug. 14.
The facility features a 6,400-square-foot
Butterfly Rainforest exhibit with water-
falls and walking trails, and thousands
of butterfly images and specimens.
