contrary to aba , kinetin increased rnase activity in the mutant under normal humidity and decreased it under high humidity.a similar incorporation of labeled uridine into rna in normal , mutant , and aba-treated mutant plants under normal humidity suggests that the difference between mutant and normal plants in respect to total , soluble , and ribosomal rna results not from a different rate of rna synthesis but from a different rate of rna degradation , i.e .
C0035668
rna
C0035701
ribosomal rna
