Comparative Physiology of Green and Albino Corn Seedlings.
Previous comparative studies of green, albino, and variegated plants have shown higher levels of soluble nitrogenous compounds and lower levels of protein nitrogen in albino or in variegated than in green tissues (6, 14). The soluble nitrogen level was reduced and the protein level was increased when carbohydrates were supplied to albino tissues and plants. Groner (6), on the basis of such find...
متن کاملS-adenosylmethionine decarboxylase of corn seedlings.
S-Adenosylmethionine decarboxylase (EC 4.1.1.50) has been purified 500-fold in 30% yield from the extract of etiolated corn seedlings (cv. Golden Crossbantam Bell). This preparation had a molecular weight of approximately 25,000. The K(m) value was 5 micromolar for S-adenosylmethionine. Methylglyoxal bis(guanylhydrazone), hydroxylamine, and sulfhydryl reagents (such as p-hydroxymercuriphenylsul...
متن کاملReversibility of chilling injury to corn seedlings.
Seedlings of corn (Zea mays) were tested for recovery from chilling injury incurred at 0.3 +/- 0.3 C. At 0.3 C visual leaf injury appeared in 36 hours, whereas stem and root injuries appeared later. Appearance of leaf injury was preceded by a rise in O(2) uptake and a lessened effect of 2,4-dinitrophenol on O(2) uptake by leaf segments and was accompanied by increased ion leakage from the leave...
متن کاملNucleotide & ribonucleic acid metabolism of corn seedlings.
The consideration of nucleotides and ribonucleic acid (RNA)2 in metabolism has become increasingly imiiportant in cellular biology during the past few years. The commonly occurring nucleotides of -wheat and corn plants have been identified by BergkN-ist (1) and Cherry and Hageman (3), respectively. The latter have shown that the nucleoside diand trip)hosphates in etiolated corn embryos shift to...
