Enhanced Activity of the Soluble Ribonucleic Acid Polymerase from 2,4-Dichlorophenoxyacetic Acid-treated Maize Seedlings

Enhanced Activity of the Soluble Ribonucleic Acid Polymerase from 2,4-Dichlorophenoxyacetic Acid-treated Maize 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...

The Involvement of Soluble Ribonucleic Acid in Amino Acid Incorporation by a Maize System.

Much evidence, accumulated within the last 7 years, implicates soluble ribonucleic acid as a natural acceptor of activated amino acids and as an intermediate in the incorporation of amino acids into microsomal protein (l-3). Hoagland et al. (4) have delineated the essential features of the involvement of sRNAl in the cell-free amino acid-incorporating system from rat liver in terms of the curre...

Ribonucleic Acid Polymerase from Micrococcus Zysodeikticus

The homopolymer complex, (dA, .dT,), will direct the synthesis of r(A),, or r(U),,, or both, in the presence of highly purified RNA polymerase from iVIicrococcus Zysodeikticus. When either ‘GATP or 3H-UTP is present with saturating amounts of (dA, . dT,), AMP incorporation is considerably greater than UMP incorporation. This difference appears to reflect a product inhibition which is observed o...

Increased ribonucleic Acid polymerase activity associated with chromatin from internodes of dwarf pea plants treated with gibberellic Acid.

Gibberellic acid increases the level of RNA polymerase associated with chromatin isolated from expanding internodes of light-grown, dwarf pea plants (Pisum sativum L.), without a detectable increase in the amount of DNA template available.
