Journal ArticleDOI
Overexpression of Arabidopsis Hexokinase in Tomato Plants Inhibits Growth, Reduces Photosynthesis, and Induces Rapid Senescence
Nir Dai,Arthur A. Schaffer,Marina Petreikov,Yosepha Shahak,Yuri E. Giller,Kira Ratner,Alex Levine,David Granot +7 more
TL;DR: Evidence is presented that hexokinase is involved in sensing endogenous levels of sugars in photosynthetic tissues and that it participates in the regulation of senescence, photosynthesis, and growth in seedlings as well as in mature plants.
Journal ArticleDOI
Sucrose-to-Starch Metabolism in Tomato Fruit Undergoing Transient Starch Accumulation.
TL;DR: Comparison of “maximal” in vitro activities of the enzymes in the Suc-to-starch pathway suggests that these same enzymes are limiting to the rate of starch accumulation.
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
Functional characterization of CmCCD1, a carotenoid cleavage dioxygenase from melon.
Mwafaq Ibdah,Yaniv Azulay,Vitaly Portnoy,Boris Wasserman,Einat Bar,Ayala Meir,Yossi Burger,Joseph Hirschberg,Arthur A. Schaffer,Nurit Katzir,Yaakov Tadmor,Efraim Lewinsohn +11 more
TL;DR: It is shown here that the CmCCD1 gene product cleaves carotenoids at positions 9,10 and 9',10', generating geranylacetone from phytoene; pseudoionone from lycopene; beta-ionOne from beta-carotene, as well as alpha-ionone and pseudoion one from delta- carotene.

Schaffer,Nurit Katzir,Yong Xu,Haiying Zhang,Nobuko Fukino,Satoru Matsumoto,Jordi Garcia-Mas,Antonio J. Monforte,Antonio J. Monforte +31 more
TL;DR: The integrated saturated map presented herein should be considered the initial reference map for melon and contains polymorphic in diverse collection of germplasm, and thus are potentially transferrable to a broad array of genetic experimentation.
