Dr. Megh Singh Receives Honor
Dr. Megh Sinmh. UF Profe'stor of Weed Science, was named Fel-
low of The Indian Society of Weed Science in March. He was invited
make a presentation on "F ffica ,i Enhancement of Pre-S.eeding, Herbi-
cides in a Zero Till System" at the International \korkhop on Herbi-
cide Resistance Management and Zero Tillage in Rice-Wheat Crop-
ping S Estenl at Haryana Agricultural University, Hisar, India, March
Dr )ingh. who has been at CREC since 1980, is work-
ing on the development of efficient and environmen-
tally-sound weed management systems for Florida cit-
rus. Specific areas of research include the efficacy of
herbicides, including chemical ,creeninr and phyto-
toxicity: weed biology : the integration of weed control
methods and production practices for citrus nurseries
and groves; allelopath, and other biological control
method, herbicide physiology, and herbicide-soil in-
teraction studies on the leaching behavior of herbicides
to reduce the risk of groundwater contamination.

At CREC. Dr. Widmer conducted research in
grapefruit juice quality improvement, the nutri- a
tional Iqualy of citrus products, method devel-
opniem for measurement ofnutrients such as folic
acid in citrus, and value-added by-products from
processing waste streams.
Dr. Lee conducted research in the processing and chemistry of juice. with emphasis on chemi-
cal and biochemical problems associated with quality and rtabilitN. including juice discoloration
and oT- II a or development.

Visit the .. Core Citrus Transformation Facility
I Dr. Vladimir Orbovic (left) at the Core Citrus Transformation Facility (CCTF) on the third floor
SCore ~of Building 24 at their Open House on April 5. The work of the CCTF involves, as a service,
-the incorporation of genes of interest into citrus cultivars for evaluation and testing. Ex-
amples may include genes that may confer disease resistance, improve cold tolerance, improve
fruit flavor and color, or are associated with other desirable traits. At the Open House, Dr.
Orbovic displayed some citrus seedlings that were engineered to express a coat protein gene
of the citrus tristeza virus (CTV). Working ith Dr. Remic Albiach-Marti, a post-doc in Dr. Bill
Dawson's laboratory, the next step is to examine whether these plants show resistance to
severe CTV strains.

A New Look
Changes abound as aci ll i improvements take place. New
\ indo\ are currenwlh being in'ralled in Building 24 ("adminis-
tration"), and the south entrance of this building will undergo
structural modifications. These changes will help modernize
the building's appearance and make the main entrance to the
reception area more prominent.
The buildings behind Building 10, including the Ag Engi-
neering workshop, % ill be taken down and replaced with a new
metal htulding in the coming weeks, and the dri.e\~ay behind
Building 10 (alongside Shippng Recei\ ingi will be redone.
Other change- include the construction of a new pole barn
and greenhouse, and several buildings will receive a fresh coat
