Some effects of 2,4-dichlorophenoxyacetic acid on soluble nucleotides & nucleic acid of soybean seedlings

Some effects of 2,4-dichlorophenoxyacetic acid on soluble nucleotides & nucleic acid of soybean seedlings.

One of the most marked biochemical changes in plants knowvn to accompany 2,4-D4 treatments is the increase in nucleic acid. Rebstock et al (33) found the nucleic acid content to double in the stems of bean plants after 2,4-D treatment. Similar increases in the RNA content of 2,4-D-treated cucumber plants were reported by West et al (40); 2.4-D treatment was also shown to alter the RNA content o...

Some effects of 2,4-dichlorophenoxyacetic acid on the oxidation-reduction state of soybean seedlings.

During a study of the effect of 2,4-dichlorophenoxyacetic acid on the soluble nucleotides in soybean seedlings (1)) a nonnucleotide compound accumulated in the treated seedlings. The same compound was found in high concentrations in immature soybean seeds that would not germinate (2). The compound inhibited seed germination and markedly affected respiration and phosphorylation of both intact so...

Metabolism of 2,4-dichlorophenoxyacetic Acid in 2,4-dichlorophenoxyacetic Acid-resistant soybean callus tissue.

Three 2,4-dichlorophenoxyacetic acid (2,4-D) -resistant root callus tissue lines of Glycine max L. Merrill var. Acme were derived by culturing callus tissue 2 to 6 months on 40 milligrams per liter 2,4-D and designated 40R, 40B, and 40C. Tissue line 40R had a lower level of 2,4-D uptake in 2-week-old tissue which disappeared in 3.5-week-old tissue and less free 2,4-D following incubation for 24...
