Germination of phaseolus vulgaris I. Resumption of axis growth.
Growth of the excised axis of Phaseolus vulgaris L. (var. White Marrowfat) begins after a 7-hour incubation in buffer or water at 26 degrees . Growth, as measured by axis elongation or fresh weight increase, is linear for at least 8 hours with a resultant fresh weight increase of approximately 65%. Cell elongation begins 4 or 5 hours prior to cell division and 5 or 6 hours prior to radicle prot...
متن کاملl-Phenylalanine Ammonia-Lyase Activity During Germination of Phaseolus vulgaris.
l-Phenylalanine ammonia-lyase (PAL) activity develops in excised bean axes after approximately 5 hours of incubation and reaches a maximum level after 14 hours of incubation. Light does not affect the development of activity, but puromycin, cycloheximide, actinomycin D, and 5-fluorouracil inhibit.During this period of incubation both d- and l-p-fluorophenylalanine stimulate fresh weight increas...
متن کاملGlycosidases of Phaseolus vulgaris
The enzymes, cr-galactosidase, P-galactosidase, a-mannosidase, P-glucosidase, and p-acetylglucosaminidase, have been purified from the germinating seeds of Phaseolus vulgaris. All five enzymes have been simultaneously isolated in a highly active form. The pH optimum, K,,,, and energy of activation of each glycosidase for the reaction of hydrolysis of the appropriate P-nitrophenyl glycoside have...
متن کاملOligosaccharide Specificities of Phaseolus vulgaris
The structural determinants required for interaction of oligosaccharides with leukoagglutinating phytohemagglutinin (L-PHA) and erythroagglutinating phytohemagglutinin (E-PHA) from Phaseolus vulgaris have been studied by immobilized lectin affinity chromatography. Homogeneous oligosaccharides of known structure, purified following release from Asn with Nglycanase and reduction with NaBH4, were ...
