Abstract
|
|
|
Wheat coleoptile sections were treated with either 1.5×10^(-5) M ABA or 5×10^(-5) M IAA in vitro, the results may be summarized as follows,
1. The treatmert of IAA decreased the level of high molecular weight RNA F2 and F3 but that with ABA increased the F4 level.
2. IAA caused an increased activity of G2 isozyme, while ABA suppressed the activity of G3 isozyme.
3. The results may suggest that there may exist common effects of IAA and ABA on RNA and RNase.
4. The latent RNase activity caused by SH blocking reagent (p-hydroxymercury benzoate, Pb et al) was not observed.
