Indoleacetic Acid synthesis in soybean cotyledon callus tissue.
Growth of an auxin-requiring soybean cotyledon callus tissue (Glycine max L., Merr. var. Acme) was promoted by tryptophan, tryptamine, indole, indoleacetamide and, to a very slight degree, anthranilic acid. When tryptophan-3-(14)C was supplied in the growth medium, labeled indoleacetic acid (IAA) was found in both the tissue and the medium. Medium, from which the cells had been removed, was als...
متن کاملPromotion of indoleacetic Acid oxidase isoenzymes in tobacco callus cultures by indoleacetic Acid.
Indoleacetic acid oxidase in tobacco callus cultures (Nicotiana tabacum L., cv. White Gold) was composed of at least two groups of isoenzymes, which were distinctly different in electrophoretic mobilities and in responses to growth substances. Indoleacetic acid had dual effects; at low concentrations it promoted the development of two fast-migrating indoleacetic acid oxidase isoenzymes, but at ...
متن کاملMetabolism 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...
متن کاملEffect of 2,4-dichlorophenoxyacetic Acid on the cytokinin requirement of soybean cotyledon and tobacco stem pith callus tissues.
Studies pertaining to the detection, isolation anid chemical characterization of naturally occurring and synthetic cytokinins have been aided by the utilization of cultured callus tissues derived from soybean cotyledons (6, 9, 10, 11, 12) and tobacco stem pith (7, 8, 13, 14). Both tissues, when exposed to a specific anid defined chemical milieu, require kinetin or another similarly active 6-sub...
متن کاملEvidence for compartmentalization of conjugates of 2,4-dichlorophenoxyacetic Acid in soybean callus tissue.
Soybean Glycine max L. Merrill var. Amsoy 71 root callus tissue labeled with [1-(14)C]2,4-dichlorophenoxyacetic acid (2,4-D) which was subsequently incubated for 24 hours in the absence of 2,4-D, released considerable amounts of label into the media. These results led to an examination of the efflux of 2,4-D and 2,4-D metabolites during a 6-hour time period. Fifty% of the free 2,4-D was lost in...
