In vitro nuclear protein phosphorylation is enhanced in nuclei isolated from 2,4-dichlorophenoxyacetic acid (2,4-d)-treated mature soybean (Glycine max) hypocotyl relative to nuclei from untreated tissue. Increased nuclear protein phosphorylation correlates with increased levels of nuclear protein kinase activity. These changes generally parallel previously reported 2,4-d-enhanced RNA polymeras...

The degradation rate of 2,4-dichlorophenoxyacetic acid (2,4-D) was studied in silica-slurry systems to evaluate the bioavailability of sorbed-phase contaminant. After the silica particles were saturated with 2,4-D, the system was inoculated with the 2,4-D-degrading microorganism Flavorbacterium sp. strain FB4. The disappearance rate of 2,4-D was found to be greater than the rate predicted based...

The influence of growth regulators on the root induction of the Musa genus plants cultivated within in vitro conditions has been compared. The plant material used was the ‘Cavendish’ cultivar. Different concentratios of growth regulators (naphthaleneacetic acid, indole-3-acetic acid, 6-benzylaminopurine, 2.,4-dichlorophenoxyacetic acid) has been used and as control ones MS and half concentrated...
