在黄瓜黄化子叶中，编码光系统I一个亚基的psaL转录的mRNA水平在黑暗中会因细胞分裂素而升高。
The level of mRNA transcribed from psaL, which encodes a subunit of photosystem I, is increased by cytokinin in darkness in etiolated cotyledons of cucumber.

Abstract
A cDNA clone for an mRNA whose level increased within 2 h of the start of treatment with N6-benzyladenine in etiolated cotyledons of cucumber was isolated by differential hybridization. The cDNA was homologous to psaL, which encodes subunit XI (PSI-L) of photosystem I. The accumulation of psaL mRNA was specifically induced by cytokinins or light.
摘要
通过差异杂交从黄瓜黄化子叶中分离出一个cDNA克隆，该克隆对应一种mRNA，其水平在N6-苄基腺嘌呤处理开始后的2小时内升高。该cDNA与编码光系统I亚基XI（PSI-L）的psaL同源。psaL mRNA的积累是由细胞分裂素或光特异性诱导的。
