Distribution of a - Galactosidase in Cucurbita pepo
The distribution of a-galactosidase (a-D-galactoside galactohydrolase IEC 3.2.1.221) in Cucurbita pepo has been determined in an attempt to assess its involvement in hydrolysis of transport sugars of the raffinose oligosaccharide series (la-1-6-galactopyranosyllj sucrose). Extracts prepared from leaves and petioles at different stages of development, roots, flowers, dry and germinating seeds, a...
متن کاملMetabolic Requirement of Cucurbita pepo for Boron.
Lateral roots of intact summer squash seedlings (Cucurbita pepo L.) were used to quantify the effects of boron deficiency on DNA synthesis, protein synthesis, and respiration. The temporal relationship between changes in these metabolic activities and the cessation of root elongation caused by boron deprivation was determined. Transferring 5-day-old squash seedlings to a hydroponic culture medi...
متن کاملUV-C irradiation reduces microbial populations and deterioration in Cucurbita pepo fruit tissue.
Tissue slices of zucchini squash (Cucurbita pepo L., cv. Tigress) fruit were exposed to ultraviolet-C (UV-C) radiation from germicidal lamps for 1, 10 or 20 min; however, only 10 and 20 min UV-C exposure significantly reduced microbial activity and deterioration during subsequent storage at 5 or 10 degrees C. UV-C treated slices had higher respiration rates than controls; however, the ethylene ...
متن کاملRegulation of Pyrimidine Biosynthesis in Intact Cells of Cucurbita pepo.
The occurrence of the complete orotic acid pathway for the biosynthesis de novo of pyrimidine nucleotides was demonstrated in the intact cells of roots excised from summer squash (Cucurbita pepo L. cv. Early Prolific Straightneck). Evidence that the biosynthesis of pyrimidine nucleotides proceeds via the orotate pathway in C. pepo included: (a) demonstration of the incorporation of [(14)C]NaHCO...
متن کاملDe Novo Purine Biosynthesis in Intact Cells of Cucurbita pepo.
The capacity of intact cells of roots excised from summer squash plants (Cucurbita pepo L. cv Early Prolific Straightneck) to synthesize purine nucleotides de novo was investigated. Evidence that purine nucleotides are synthesized de novo included: (a) demonstration of the incorporation of [1-(14)C]glycine, [2-(14)C]glycine, NaH(14)CO(3), and H(14)COONa into total adenine nucleotides; (b) obser...
