Abstract
The effect of gibberellic acid (GA) on total RNA and polysomal poly-[A]+-RNA synthesis in epicotylia and embryos of dwarf pea of two varieties differing in their physiological sensitivity to GA was studied. It was found that incubation with GA increases the accumulation of total RNA in pea epicotylia, var. "Pioner" and "Polzunok". The maximal stimulation of RNA accumulation makes up to 40% for the low sensitivity variety "Polzunok" and 150% for the highly sensitive variety "Pioner". GA increases the synthesis of polysomal poly (A)+-mRNA in 5-year-old pea sprouts and that of newly synthesized poly (A)+-mRNA in epicotylian polysomes of both varieties 5, 24, 48 and 72 hrs after incubation with GA. GA at concentrations of 10(-6) and 10(-5) stimulates the incorporation of [3H]uridine into polysomal mRNA during the first 1--3 hours after treatment and enhances the accumulation of newly synthesized mRNA in pea embryonic polyribosomes. The stimulating effect is directly proportional to the dose of the hormone. The mechanisms of GA effect on the transcription and translation in pea plant cells are discussed.
