We report the isolation of a turgor-responsive gene of pea, trg-31, whose transcription induced within 30 min after the loss of leaf turgor. Structure of the coding region and 1.4 kb of 5' untranslated region was determined by DNA sequencing. A 3 kb promoter fragment from trg-31 was fused to a beta-glucuronidase (GUS) reporter gene in pBI101, tobacco leaf disks and mature plants analyzed for turgor-responsive induction of GUS mRNA. Significant amino acid sequence homology exists between trg-31 and putative transport proteins of bovine, Phaseolus, soybean and Escherichia coli membranes.
我们报道了豌豆中一个膨压响应基因trg - 31的分离,其转录在叶片膨压丧失后30分钟内被诱导。通过DNA测序确定了编码区结构和1.4 kb的5'非翻译区。将来自trg - 31的3 kb启动子片段与pBI101中的β - 葡萄糖醛酸酶(GUS)报告基因融合,对烟草叶盘和成熟植株进行分析,以检测GUS mRNA的膨压响应诱导情况。trg - 31与牛、菜豆、大豆和大肠杆菌膜的推定转运蛋白之间存在显著的氨基酸序列同源性。
