Association of Phytochrome with Rough-surfaced Endoplasmic Reticulum Fractions from Soybean Hypocotyls.
Distribution of phytochrome (as Pfr) among membranes from soybean hypocotyls (Glycine max L. cv. Wayne) was determined by the combined techniques of cell fractionation, difference spectrometry, and electron microscopic morphometry. More than 90% of the phytochrome was found in the soluble fraction. With homogenates prepared in the presence or absence of Mg(2+), the portion associated with membr...
متن کاملNADH Oxidase Activity of Plasma Membranes of Soybean Hypocotyls Is Activated by Guanine Nucleotides.
The activity of an auxin-stimulated NADH oxidase of the plasma membrane of hypocotyls of etiolated soybean (Glycine max Merr.) seedlings responded to guanine and other nucleotides, but in a manner that differed from that of enzymes coupled to the classic trimeric and low molecular weight monomeric guanine nucleotide-binding proteins (G proteins). In the presence and absence of either auxin or d...
متن کاملHistone Kinase from Soybean Hypocotyls: PURIFICATION, PROPERTIES, AND SUBSTRATE SPECIFICITIES.
A histone-type protein kinase (EC 2.7.1.37) has been partially purified (320-fold) from the crude extracts of soybean hypocotyls by means of a combination of gel filtration and anion exchange procedures. The purified enzyme fraction is devoid of the activities of phosphoprotein phosphatase (EC 3.1.3.16), histone protease, and casein (or phosvitin)-type kinase. The soybean histone kinase uses AT...
متن کاملMetabolic Regulation during Glyceollin Biosynthesis in Green Soybean Hypocotyls.
The accumulation of the isoflavonoid phytoalexin, glyceollin, occurs in hypocotyls of green soybean seedlings (Glycine max L. Merr. cv Harosoy 63) in response to the injection of a glucan elicitor isolated from the mycelial walls of the fungus, Phytophthora megasperma f. sp. glycinea. This accumulation, which levels off after 24 hours, is preceded by a dramatic, transient rise in extractable ac...
