Plant science driven by Galilee challenges USING MOLECULAR BIOLOGY TECHNOLOGIES FOR OVERCOMING FERTILITY AND QUALITY CONSTRAINS IN DECIDUOUS TREE PLANTATIONS IN NORTHERN ISRAEL Developing a young local scientific leadership that will support and advance agriculture in the Galilee ICA charitable foundation MIGAL – Galilee Technological center Northern agriculture R&D
1) Pollination and fertilization, means for improving yields and fruit quality Gal Sapir, Ph. D. from 10. 08 (Kibbutz Kfar Giladi) Fertilization in plums. Joined Migal. Amir Raz, Ph. D. student (Kibbutz Lavi) Fertilization in apricots Annat Zosovich, Ph. D. student (Kibbutz Iftach) Fertilization in pears Principal investigators: Dr. Raffi Stern, plant physiology Prof. Martin Goldway, plant molecular genetics
• The Galilee is the major supplier of plum pears and apricots • Far below their biological potential. Our goal: Higher yields with better quality fruits. Our approach: • Apples, pears, plums, apricot do not self pollinate • Efficiency of cross pollination depends on genetic compatibility • We are studying the mechanism of fertilization P 2 P 1 P 3
Molecular markers Genetic compatibility between cultivars Field experiments Results: • Identification of cultivars which are better pollinators • As a result yields are higher and the fruit quality is better
2)Understanding ripening for prolonging fruit storage Danny Gamrasny, Ph. D. student (Kibbutz Shamir) Post harvest storage of pears Danny Lishansky, M. Sc. student (Moshav Almagor) Post harvest storage of Mango Principal investigators Prof. Ruth Ben Arie, fruit post harvest Prof. Martin Goldway, plant molecular genetics
Our goal: To find the conditions for prolonging storage Our approach: • To study fruit ripening applying high throughput molecular genetics • To investigate the storage condition with new kinds of ripening inhibitors Results: • Novel genes controlling the ripening process were identified • Conditions and treatments for prolonging the storage of both pears and mango were identified
3) Pomegranate fruit: An analytical platform for food functionality. Elinor Shwartz, M. Sc. Student (Kibbutz Dafna) Inhibition of the proliferation of prostate cancer Ira Glazer, M. Sc. Student (Kiryat Shmona) Detection of bio-active compound that reduced arthrosclerosis Revital Tzulker, M. Sc. Student (Kiryat Shmona) Compounds with antioxidant activity, Principal investigators: Prof. Rachel Amir, plant metabolomics Dr. Yigal Bar Ilan, analytical chemistry
• Pomegranate contain bioactive compounds. • The Upper Galilee will produce, with in two years, a quarter of the total Israeli pomegranate yield. Our goals: To elucidate their bioactive compounds (antioxidant and anti-cancer) in different pomegranate varieties. Our approach: A molecular comparative analysis of pomegranate varieties Identify and determine there bioactive compounds
Results: So far, 4 compounds that reduced bloodpressure, cholesterol accumulation and arthrosclerosis. Our vision: To produce new highly specialized pomegranate orchards with cultivars that produce bioactive compounds for the medical and cosmetic industry.
