Excised pea plants were rapidly dehydrated to turgor pressures of 1.5 to 2.0 bars. After a 30 minute lag, abscisic acid (ABA) levels increased approximately 100-fold in the dehydrated plants. Pretreatment of plants with the transcription inhibitors actinomycin D or cordycepin or with an inhibitor of cytoplasmic protein synthesis prior to plant dehydration inhibited the synthesis of ABA. These results suggest that dehydration induced synthesis of ABA requires nuclear gene transcription.
切除的豌豆植株迅速脱水至膨压 1.5 至 2.0 巴。经过 30 分钟的延迟，ABA（脱落酸）水平在脱水植株中增加了约 100 倍。在植物脱水之前，用转录抑制剂放线菌酮或虫草素或细胞质蛋白合成抑制剂预处理植物，抑制 ABA 的合成。这些结果表明，脱水诱导的 ABA 合成需要核基因转录。
