De 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...
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 کاملDistribution 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 کاملDevelopment of Advanced Interspecific-bridge Lines among Cucurbita pepo, C. maxima, and C. moschata
Interspecific hybridization among the three most economically important cultivated species of Cucurbita spp., Cucurbita pepo, C. moschata, and C. maxima can be made but not readily. By means of various pollination measures, different mating systems, and varying selection methods, nine advanced interspecific-bridge lines were developed, in which the crossing barrier among the species and the mal...
