Glycine max (soybean) is the only known higher plant with a definitely established occurrence of somatic crossing over. This material lends itself to the analysis of somatic crossing over, gross chromosomal aberrations and mutations, all of which may be induced by the same treatment of the mutagen
Aspartate transcarbamylase (ATCase) activity declines in etiolated cowpea (Vigna unguiculata L. Walp.) and soybean (Glycine max L. Merr.) hypocotyls between 3 and 11 days after planting. Treating cow-pea hypocotyls with cycloheximide (CH), actinomycin D (AMD), 6-methyl purine (6-MP), or cordycepin
Activity of nitrate reductase in roots and cotyledons of cotton seedings (Gossypium hirsutum L. cv. Deltapine 16) increased rapidly on germination, reaching a maximum after 1 day of imbibition. Thereafter, activity declined until emergence and greening of the cotyledons, when it again began to
In vitro translation products of polyadenylated RNA from untreated and auxin-treated elongating sections of soybean (Glycine max var. Wayne) hypocotyl were analyzed by two-dimensional polyacrylamide gel electrophoresis. The levels of translatable messenger RNA for at least ten in vitro translation
Chromatin isolated from soybean (Glycine max L., var. Wayne) hypocotyls was capable of catalyzing the polymerization of labeled deoxyribonucleoside triphosphate in the presence of the three other deoxyribonucleoside triphosphates into a trichloroacetic acid-insoluble product. This product was
Actinomycin D inhibited the synthesis of poly(A)-containing messenger RNA in healthy soybean (Glycine max [L.] Merr. cv. Harosoy 63) hypocotyls and in hypocotyls inoculated with the pathogenic fungus Phytophthora megasperma var. sojae A. A. Hildb., but had little effect on protein synthesis within 6
The levels of the activities of argininosuccinate synthetase and argininosuccinate lyase were measured in soybean (glycine max L. var. Mandarin) cell suspension cultures grown in the presence or absence of exogenous arginine. In some experiments, actinomycin D or cycloheximide were also added to the
In animal cells specialized for iron storage, iron-induced accumulation of ferritin is known to result from a shift of stored mRNA from the ribonucleoprotein fraction to polysomes. Previous reports with bean leaves suggested that in plants iron induction of ferritin synthesis would result from a
The restriction endonuclease map of the 25 S and 18 S ribosomal RNA genes of a higher plant is presented. Soybean (Glycine max) rDNA was enriched by preparative buoyant density centrifugation in CsCl-actinomycin D gradients. The buoyant density of the rDNA was determined to be 1.6988 g cm(-3) by
