Abstract

Gibberellicacid-induced dark germination of Grand Rapids lettude seed was completely inhibited by 6-azauracil and partly by 2-thiouracil. Other inhibitors of nucleic acid and protein synthesis used were without effect. Inhibition of gibberellic acid-induced dark germination was reversed by uracil but not by thymine, deoxycytidine and orotic acid. The results suggest that gibberellic acid-induced dark germination is dependent on RNA synthesis and not on DNA synthesis.Gibberellic acid-induced lettuce hypocotyl growth was inhibited by all the inhibiters of nucleic acid and protein synthesis used, including actinomycin D, puromycin, chloramphenicol and p-fluorophenylalanine.

摘要

赤霉素诱导的大 Rapids 生菜种子的暗发芽完全被 6-氮杂尿嘧啶和部分 2-硫代尿嘧啶抑制。其他核酸和蛋白质合成抑制剂则没有效果。尿嘧啶可以逆转赤霉素诱导的暗发芽的抑制，但胸腺嘧啶、脱氧胞苷和乳清酸则不行。结果表明，赤霉素诱导的暗发芽依赖于 RNA 合成，而不是 DNA 合成。赤霉素诱导的生菜下胚轴生长被所有核酸和蛋白质合成抑制剂抑制，包括放线菌素 D、嘌呤霉素、氯霉素和对氟苯丙氨酸。
