Work in Dominica

ofInternational FOCUS, the newsletter of
the UF/IFAS International Programs.

A trip to Dominica to work on citrus
tristeza virus in March provided UF/IFAS
professor Dr. Ron Brlansky an opportunity
to go to the front line in Florida's defense
against citrus diseases.
Dr. Brlansky and technical assistant
Deborah Howd, both from CREC in Lake
Alfred, taught citrus tristeza diagnostic
methods to Dominica officials in the
Ministry of Agriculture's plant protection
and quarantine program. While in
Dominica, Dr. Brlansky was able to examine
strains of citrus tristeza virus that are present
in the Caribbean and other citrus diseases
in Dominica that could threaten Florida's
citrus industry.
The citrus industry is in decline in
Dominica, but the Ministry of Agriculture
has initiated a program to revitalize the in-
dustry. One component of that program
involves shifting citrus production from
sour orange rootstock to rootstocks that
are resistant to the decline. The virus is
transmitted by the brown citrus aphid,
which also is present in Florida.
Another potential threat is citrus green-
ing disease. The insect psyllid vector al-
ready is present in Florida. Dr. Brlansky vis-
ited numerous groves in Dominica but did
not find the psyllid or the disease.
On this trip, March 14-25, Dr. Brlansky
did not observe any other exotic diseases
that could threaten Florida's citrus indus-
try. In the future, the cooperative work with
Dominica scientists will enhance UF/IFAS
scientists' ability to detect migrating citrus
diseases and to prepare defenses against

Postbloom Fruit Drop

Paper Receives

ASHS Award

A paper by CREC scientists W. Li, R.
Yuan, J.K. Burns, L.W. Timmer and KR.
Chung was selected as the American Soci-
ety for Horticultural Science Outstanding
Cross Commodity Publicationfor2004. The
paper, "Genes for hormone biosynthesis
and regulation are highly expressed in cit-
rus flowers infected with the fungus
Colletotrichum acutatum, causal agent of
postbloom fruit drop," was published in the
Journal of the American Society for Horti-
cultural Science (JASHS 128:578-583,
2003), and was selected from all papers pub-
lished in JASHS, HortScience and
HortTechnology in 2003. The authors will
be honored at an awards ceremony at the
ASHS Annual Meeting on July 17 in Aus-
tin, Texas. In addition, an enlarged version
of the paper will displayed with other Out-
standing Publications at the meeting. The
research is funded in part by a grant from
the Florida Citrus Production Research Ad-
visory Council (Florida citrus growers).
Dr. Chung, the lead investigator on the
study, joined the CREC faculty in Lake
Alfred as Assistant Professor of Plant
Pathology in 2000. His current research
program focuses on fungal genes involved
in the development of postbloom fruit drop
in citrus. A native of Taiwan, Dr. Chung
received his B.S. and M.S. degrees in Plant
Pathology from the National Chung-Hsing
University in Taiwan. He received his Ph.D.
in Plant Pathology 1996 from the University
of Kentucky, and also worked as a
postdoctoral scientist with Dr. Margaret
Daub at North Carolina State University,
where he studied the molecular regulation
of toxin resistance and toxin production by
the fungus, Cercospora.

system. This new system promises to more efficiently manage
most of our business functions, providing more timely and
effective information and resource management. However,
these major transitions do not occur unnoticed. As indicated
in the memo from CREC Personnel (right), there will be some
adjustments to normal business during the transition, and we
will need to do everything possible to shift between systems.
The CREC Business and Personnel Offices are trying to
anticipate, and are asking for your assistance and patience
while we go through this change. Please follow their counsel
and make it easier on all of us.
Since the new system will require more end-user interaction,
we are requesting that all UF CREC employees pursue the
steps to acquire a gatorlink account, the gateway to your
access to the new system. You will find that this is your access
to leave and pay stub information, as well as other information
and services. Each UF employee requires an individual
gatorlink account, and if you haven't set one up, please go to

Important Memo from CREC Personnel

Schedule Changes For Bridges Transition

During May and June, the CREC
Personnel Office expects an in-
crease in activity relating to the
upcoming transfer of records and
systems to the new PeopleSoft
system expected to begin in July.
For Time and Labor (Payroll)
purposes, this change will take
effect June 18, 2004. Inconjunc-
tion with these changes, the UF
Division of Human Resources
will not process any personnel
actions June 10- 17,2004. The
IFAS Human Resources office
will stop processing personnel
actions during the same time
period and will notprocess non-
essential personnel actions
during the entire month ofJune.

With these facts in mind, the
CREC Personnel office will be

* UF Division of Human
Resources: no personnel actions
will be processed June 10 17.

* IFAS Human Resources: no non-
essential personnel actions will be
processed in June.

* CREC Personnel: personnel-
related transactions by
appointment only in May and

* Grant-funded position and OPS
assignments reappointment
paperwork must be submitted by
May 28 to avoid delay or break
in paid work time.

severely limited as to the types of personnel transactions that we will be
able to accomplish during late May and the entire month of June. There-
fore, all CREC Lake Alfred employees that need to initiate personnel-
related transactions in May and June are asked to do so by appointment
only. During June, we will attempt to serve your needs as best we can.
However, we may not be able to accommodate all your requests and we
intend to close our doors as necessary in order to meet the deadlines set
for us by the University.

It is particularly important that all personnel reappointments (grant-funded
positions and OPS assignments) for the period beginning July 1 be accom-
plished prior to the main period of activity in June. Thus, the CREC Per-
sonnel office requests that you turn in all completed reappointment paper-
work by May 28. Any reappointments turned in after this date may be held
until after July 1, when the new system is up and running and we are back
on line. This means that delays in reappointment will result in a gap in paid
work time until the appointment is complete.

We hope things will return to near normal sometime in July but wish to
remind all employees that we will be learning and implementing new proce-
dures that may take some period of time to master. We appreciate everyone's
patience during this time of transition. We are prepared to work with you
now to avoid problems during this forthcoming period of uncertainty.

FCPRAC Approves $2 Million for Production Research

The Florida Citrus Production Research
Advisory Council (FCPRAC) approved 29
research proposals submitted by scientists
at UF and the USDA for funding in the 2004-
2005 fiscal year. Funds for this program
come from a self-imposed tax of $0.75 per
box of fruit produced, sometimes referred
to as the research box tax. Florida citrus
growers began this research funding pro-
gram 12 years ago in attempt to supple-
ment shortfalls in research funding.
A wide variety of proposals were ap-
proved, all of which are directly related to
production. The largest portion of the
funds was allocated to citrus genetics,
breeding and plant improvement research.
While such studies are often long term ba-
sic science efforts, the FCPRAC believes
that this is the area where breakthrough
results are most likely to be forthcoming.
Substantial efforts in citrus tristeza virus
(CTV) and Diaprepes root weevil were also
approved for funding. Other projects in
plant pathology, entomology and manage-
ment were also funded.
In the 12-year history of the program,
Florida citrus growers have provided nearly
$20 million for citrus production research.
Dr. Larry Jackson retired as the FCPRAC
scientific research coordinator. Dr. Steve
Rogers is the new scientific research coor-
(Excerpted from a FCPRAC news release
by Dr. Larry K. Jackson).

Below is an overview of some of the major
CREC projects funded by the FCPRAC.
For more information, the FCPRAC Annual
Reports can be accessed online:

Plant Improvement
Scientists are using traditional breeding
techniques as well as new genetic tools to
develop scions and rootstocks with
characteristics such as disease and pest
resistance, enhanced juice and fruit quality
and extended harvesting seasons. Some
specific projects include new mandarins for
the fresh market, Diaprepes-tolerant
rootstocks and tristeza resistant varieties.
The UF/IFAS plant improvement research is
led by Dr. Jude Grosser, Dr. Fred Gmitter, Dr.
Bill Castle (CREC) and Dr. Gloria Moore

Citrus Tristeza Virus
A block grant for citrus tristeza virus (CTV)
research includes Dr. William Dawson, Dr.
Steve Garsey and Dr. Richard Lee (UF/IFAS
CREC), Dr. Tim Gottwald, Dr. Mark Hilf and
Dr. Scott Adkins (USDA-ARS Horticultural
Research Laboratory in Ft. Pierce), Dr. Peggy
Sieburth ( FDACS/Division of Plant
Industry). In the past year, progress was
made on developing laboratory detection
methods to distinguish between severe exotic
strains of CTV and decline strains already
present in Florida. Work on the molecular

genetics of CTV has contributed to further
experiments on the use of strains to provide
cross-protection against severe CTV

Diaprepes Root Weevil
Research on Diaprepes root weevil, a
devastating pest of citrus and other crops,
involves UF/IFAS CREC, USDA-ARS inFt.
Pierce, FDACS/DPI and UF-Gainesville.
CREC researchers include Drs. Larry
Duncan, Clay McCoy, Herb Nigg, Robin
Stuart, Jim Graham, Jim Syvertsen, Arnold
Schumann, Jude Grosser and their lab
In the area of biological control,
researchers are seeking to improve the use
of parasitic nematodes for Diaprepes
larvae. Investigations on egg parasitoids
and other insects predators of Diaprepes
are also underway. Otherbiological control
strategies being explored include the use
of viruses that infect Diaprepes and novel
plant compounds as biopesticides.
Promising new rootstocks developed by
UF/IFAS and USDA scientists are
exhibiting good growth in Diaprepes-
infested areas. A project is also underway
to study soil characteristics and the effects
of flooding on citrus tree growth, and how
these factors affect the ability of trees to
withstand Diaprepes-Phythophthora.
