Journal ArticleDOI
Delayed leaf senescence induces extreme drought tolerance in a flowering plant
Rosa M. Rivero,Mikiko Kojima,Amira Gepstein,Hitoshi Sakakibara,Ron Mittler,Shimon Gepstein,Eduardo Blumwald +6 more
TL;DR: In this article, a transgenic plant expressing an isopentenyltransferase gene driven by a stress-and maturation-induced promoter was used to suppress the senescence of leaves during a long drought period.
Journal ArticleDOI
Large-scale identification of leaf senescence-associated genes
Shimon Gepstein,Gazalah Sabehi,Marie-Jeanne Carp,Taleb Hajouj,Mizied Falah Orna Nesher,Inbal Yariv,Chen Dor,Michal Bassani +7 more
TL;DR: The large repertoire of SAGs identified here provides global insights about regulatory, biochemical and cellular events occurring during leaf senescence, and is likely to participate in macromolecule degradation, detoxification of oxidative metabolites, induction of defense mechanisms, and signaling and regulatory events.
Journal ArticleDOI
Enhanced Levels of the Aroma and Flavor Compound S-Linalool by Metabolic Engineering of the Terpenoid Pathway in Tomato Fruits
Efraim Lewinsohn,Fernond Schalechet,Fernond Schalechet,Jack Q. Wilkinson,Kenji Matsui,Yaakov Tadmor,Kyoung-Hee Nam,Orit Amar,Orit Amar,Elena Lastochkin,Olga Larkov,Uzi Ravid,William R. Hiatt,Shimon Gepstein,Eran Pichersky +14 more
TL;DR: It is shown that tomato plants transgenic for a heterologous Clarkia breweri S-linalool synthase (LIS) gene, under the control of the tomato late-ripening-specific E8 promoter, synthesize and accumulate S- linalool and 8-hydroxylinalool in ripening fruits.
Journal ArticleDOI
Branched-chain and aromatic amino acid catabolism into aroma volatiles in Cucumis melo L. fruit
Itay Gonda,Itay Gonda,Einat Bar,Vitaly Portnoy,Shery Lev,Joseph Burger,Arthur A. Schaffer,Yaakov Tadmor,Shimon Gepstein,James J. Giovannoni,Nurit Katzir,Efraim Lewinsohn +11 more
TL;DR: The results presented here indicate that in melon fruit tissues, the catabolism of amino acids into aroma volatiles can initiate through a transamination mechanism, rather than decarboxylation or direct aldehyde synthesis, as has been demonstrated in other plants.
Journal ArticleDOI
Progressive Inhibition by Water Deficit of Cell Wall Extensibility and Growth along the Elongation Zone of Maize Roots Is Related to Increased Lignin Metabolism and Progressive Stelar Accumulation of Wall Phenolics
TL;DR: It is suggested that spatially localized changes in wall-phenolic metabolism are involved in the progressive inhibition of wall extensibility and root growth and may facilitate root acclimation to drying environments.
