Physiological and Biochemical Regulation of Dormancy and Sprouting in Potato Tubers (Solanum tuberosum L.)
At harvest, potato (Solanum tuberosum L.) tubers are in a dormant state and do not have the ability to sprout. After harvesting, tuber dormancy is released progressively. This release is accompanied by numerous physiological and biochemical changes, such as carbohydrate hydrolysis and the accumulation of saccharides, which are detrimental to the nutritional and processing qualities of potatoes....
متن کاملSelection of Reference Genes for Transcriptional Analysis of Edible Tubers of Potato (Solanum tuberosum L.)
Potato (Solanum tuberosum) yield has increased dramatically over the last 50 years and this has been achieved by a combination of improved agronomy and biotechnology efforts. Gene studies are taking place to improve new qualities and develop new cultivars. Reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) is a bench-marking analytical tool for gene expression analysis, but ...
متن کاملPurification and Properties of Fructokinase from Developing Tubers of Potato (Solanum tuberosum L.).
Fructokinase has been purified from developing potato (Solanum tuberosum L.) tubers by a combination of hydrophobic interaction, affinity chromatography, and gel filtration. The protein has a native molecular mass of approximately 70 kD but is apparently a dimer. Ion-exchange chromatography and two-dimensional western blots resolved three major fructokinases, designated FK-I, FK-II, and FK-III ...
متن کاملLipid and oxylipin profiles during aging and sprout development in potato tubers (Solanum tuberosum L.).
Potato tubers (Solanum tuberosum L. cv Bintje) were stored at 20 degrees C for 210 days without desprouting to study the lipoxygenase pathway during aging. After 15 days of storage, potato tubers sprouted, while after 45-60 days, apical dominance was lost and multiple sprouts developed. Analysis of the fatty acid hydroperoxides (HPOs) revealed that 9-S-hydroperoxide of linoleic acid (9-HPOD) wa...
متن کاملThe ascorbate system and lipid peroxidation in stored potato (Solanum tuberosum L.) tubers
The changes in the components of the ascorbateglutathione system during the storage of potato {Solanum tuberosum L. cv. Spunta) tubers for 40 weeks at both 3 C and 9 C were studied in relation to lipid peroxidation. The level of malondialdehyde was found to be higher at 3 C than at 9 C throughout storage. Thus, lipid peroxidation, which is the main cause of membrane deterioration, was accelerat...
