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

Plant science driven by Galilee challenges

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 physiologyProf. Martin Goldway, plant molecular genetics

1) Pollination and fertilization, means for improving yields and fruit quality

•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

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 harvestProf. 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

Principal investigators: Prof. Rachel Amir, plant metabolomics Dr. Yigal Bar Ilan, analytical chemistry

Revital Tzulker, M.Sc. Student (Kiryat Shmona)Compounds with antioxidant activity,

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

3) Pomegranate fruit: An analytical platform for food functionality.

• 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 blood-pressure, 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.
