Vacuoles isolated from pea (Pisum sativum), and wheat (Triticum aestivum) leaf protoplasts contained considerable activities of electrophoretically highly mobile exoamylases. Vacuoles from spinach (Spinacia oleracea) leaf and photoautotrophic Chenopodium rubrum suspension culture cell protoplasts were devoid of amylolytic activity. Endoamylase activity was in all cases associated primarily with...

Alkaline phytase activity, with a pH optimum of 8, was recovered from detergent extracts of dormant seeds of nine varieties of Phaseolus vulgaris L., Pisum sativum L. var. Early Alaska, and Medicago sativa L. This alkaline phytase of legume seeds was activated by calcium and differed from most seed phytases in its relative insensitivity to inhibition by fluoride.

A polyadenylate-binding protein (PABP) was purified from cellfree extracts prepared from pea seedlings (Pisum sativum) by ammonium sulfate precipitation and Affi-Gel Blue and polyadenylate-Sepharose 4B affinity chromatography. The final preparation from polyadenylate-Sepharose 4B columns contained a single 70-kilodalton polypeptide with high polyadenylate-binding activity. The purified protein ...

This review is devoted to the Pisum sativum L. growth mutants. These mutants are presented by several groups of plants. The first group is characterized by short internodes (dwarf mutants le, na, lk, la, lh, ls) or by elongated internodes (slender mutant sln). The stem growth of mutants of both types (dwarf and slender) is controlled by hormones (GA and IAA) in the stem or in seeds. Mutants cha...

Seven peas (Pisum sativum L.) varieties different originated, i.e, X07P54, X06PWY, NDPO80138-B-2, CA1P, L020140, Wt6803 and Mir were studied. Biochemical assessment of fresh aboveground biomass seeds done. At the beginning flowering stage NDPO80138-B-2 X07P54 reported high levels for crude protein (22.33% 21.87%), fibre (25.94% 25.76%) ash (10.39% 9.47%). In technical maturity with contents (21...
