Biography
Professor (A+) at the ARO, The Volcani Center, Institute of Plant Sciences
Over the past 30 years I have developed as one of the leading viticulture researchers in Israel. In the academic front, I have taught the only University course on the subject for 15 years, and trained over 20 Ms.C., Ph.D. students, and postdocs, some of which have continued to play roles in Israeli and international viticulture. In the industry front, I serve as the address for extension agents and growers in Israel and abroad with regard to grape physiology.
Education
-
1986-1991
Ph.D. in Virology at the Faculty of Life Sciences, Tel-Aviv University Title of thesis: Genetic analysis of the bacteriophage P1 lytic replicon Supervision by: Prof. Gerald Cohen
-
1991-1994
Postdoctoral position at the Department of Plant Sciences of the University of Arizona with Prof. Brian Larkins Research subject: Studies of the molecular mechanisms involved in maize endosperm development
Research Interests
Research in my lab:
- shed light on the cascade of biochemical events that regulate grape bud dormancy release, which was of limited understanding, and contributed to development of bud breaking agents
- allow manipulation of grapevine bud dormancy release by optimization of HC application and development of two HC alternatives, including BudUp, the first powerful and non-toxic alternative to HC
- allowed optimization of the timing of HC application under commercial conditions within a large scale in Israel
- resulted in the development of novel heat shock generator that induce bud break under vineyard conditions
- revealed that limiting competition via regulation of flower load improves uniformity of berry size within the cluster. It allowed us to develop a novel and reliable thinning protocol that improves quality and save labor costs
- led to the identification and functional characterization of the component of GA signaling in grapevine
- revealed that citokinin – regulated VvTFL1 expression is essential for inflorescence primordia development within the bud
Research Areas
- grapevine physiology
- regulation of bud dormancy cycle-molecular mechanisms and horticultural manipulations
- Control of berry uniformity
