Sorbitol metabolism and sink-source interconversions in developing apple leaves.
In apple (Malus domestica Borkh.) sorbitol is the primary product of photosynthesis, the major translocated form of carbon, and a common fruit constituent and storage compound. Previous work on sorbitol metabolism has revealed a NADPH-dependent aldose 6-phosphate reductase (A6PR) in green tissues, and a NAD-dependent sorbitol dehydrogenase in nongreen tissues. Results here show a decrease in so...
متن کاملSink–source Transition in Peach Leaves during Shoot Development
Net photosynthesis, dark respiration, chlorophyll and carbohydrate content, and leaf and shoot growth of deciduous peach [Prunus persica (L.) Batsch] saplings, grown in greenhouse conditions, were measured to assess changes in carbon balance during leaf development. The 6th, 12th, and 16th leaf node were measured from the first flush at the base through expansion to maturity (the first node bei...
متن کاملPurification and characterization of sorbitol-6-phosphate phosphatase from apple leaves
Sorbitol-6-phosphate phosphatase (SorPP; EC 3.1.3.50) catalyzes the final step in sorbitol biosynthesis in sorbitol-synthesizing plant species, but its kinetic and regulatory properties have not been characterized. In this study, the enzyme was purified 1727-fold to apparent homogeneity from apple leaves with a maximal specific activity of 89.8 mmol min 1 mg 1 protein measured at 2 mM sorbitol-...
متن کاملCloning, expression, and characterization of sorbitol transporters from developing sour cherry fruit and leaf sink tissues.
The acyclic polyol sorbitol is a primary photosynthetic product and the principal photosynthetic transport substance in many economically important members of the family Rosaceace (e.g. almond [Prunus dulcis (P. Mill.) D.A. Webber], apple [Malus pumila P. Mill.], cherry [Prunus spp.], peach [Prunus persica L. Batsch], and pear [Pyrus communis]). To understand key steps in long-distance transpor...
متن کاملUbiquitous distribution and different subcellular localization of sorbitol dehydrogenase in fruit and leaf of apple
NAD(+)-dependent sorbitol dehydrogenase (NAD-SDH, EC 1.1.1.14), a key enzyme in sorbitol metabolism, plays an important role in regulating sink strength and determining the quality of apple fruit. Understanding the tissue and subcellular localization of NAD-SDH is helpful for understanding sorbitol metabolism in the apple. In this study, two NAD-SDH cDNA sequences were isolated from apple fruit...
