The relationship between ribulose diphosphate carboxylase (3-phospho-d-glycerate carboxy-lyase [dimerizing], EC 4.1.1.39, formerly known as carboxydismutase) and protochlorophyllide holochrome of etiolated Phaseolus vulgaris leaves has been studied.A procedure for partially selective extraction of
Potassium naphthenate, 20 mm, was applied to the foliage of 14-day-old plants of bush bean, Phaseolus vulgaris L, cv Top Crop, maize, Zea mays L, cv Golden Bantam, spring wheat, Triticum vulgare Vill., cv Neepawa, and a 2 mm solution to 21-day-old plants of sugar beet, Beta vulgaris L, cv CS-43.
