Nicotinamide Adenine Dinucleotide in Potato Tuber Slices in Relation to Respiratory Changes with Age.
The respiration of slices of a variety of bulky storage tissues rises gra(lually three to fourfold within a (lay of cutting (7, 8, 9, 10). The respiration rate of freslh tissue cani be sharply raise(d ith 2,4 dinitrophenol, however, as (lemionstrate(I in chlicory and potato slices. Both the age-inducedI an(d DNPinducedl respiration incremzents are inhibite(d by imalonate. It has been sh]own tha...
متن کاملChanges in sucrose synthetase activities in aging potato tuber slices.
The me-chanism by which the reversible conversion of starch ito sucrose takes place in potato tubers exposed t,o cold is as yet essentilally unknown. Early 'studies on the subjectt tried to correllate this conversion with va,riations in the activity of related enzymes (10). Those responsible for the synthesis of sucrose and sticrose-6--phosphiate (1) are undoubtedly highly relevant. In add'itio...
متن کاملActivation of protein synthesis in aging potato tuber slices.
LiCI-extraction of RNAs from isolated ribosomes, however, destroys the coding properties of mRNAs (as has been shown with cerebral mRNA; P. MANDEL, pers. comm.). Therefore separation of mRNAs from ribosomes was achieved by EDTA. If isolated ribosomes from intact potato tubers are dissociated into subunits and RNAs by EDTA, sucrose density gradient profiles show the presence of the 60Sand 40S-su...
متن کاملCitric-acid Induced Loss of Rigidity in Potato Tuber Slices.
and petiole, the interveinal tissue did not reach tritium equality with major veins, the stem, or the external solution. Water of the interveinal tissue maintained a stable tritium content at 60 to 70 % of external concentration for long periods. The pattern of results obtained was similar in sunflower and tobacco. Tritium content of leaf-tissue water vapor transpired by the canopy of an intact...
متن کاملMultiple signaling pathways control tuber induction in potato
Potatoes (tubers of Solanum tuberosum) are grown and eaten in more countries than any other crop, and in the global economy they are the fourth most important crop after the three cereals maize, rice, and wheat. Therefore, research into potato tuber initiation and development, which enables our understanding and possible manipulation of these processes, is of great relevance. In addition to imp...
