摘要: 从水稻愈伤组织抑制消减杂交(suppression subtractive hybridization, SSH)文库中分离出一个PCD相关基因的EST片段,根据水稻基因组的序列设计引物,从汕优63中分离与克隆出rPDCD5的全长cDNA。rPDCD5包含387bp的可译框,编码由128个氨基酸构成的蛋白质。序列比对分析显示,该检测的蛋白质与已知PDCD5的高度同源。半定量实时PCR分析证实了该基因在环境因子(低温处理和NaCl处理)胁迫下表达呈正调控。

Abstract: An EST related to the gene PCD was isolated from SSH (suppression subtractive hybridization) library of callus tissues of rice (Oryza sativa L.). Primers were designed to obtain its complete cDNA encoding putative apoptosis-related protein from Shanyou 63 (Oryza sativa L.). Sequencing indicated that the gene contained a 387 bp open reading frame, which encodes a protein containing 128 aa. Sequence alignment showed that the deduced protein is highly homologous to the known PDCD5. Real time quantitative PCR was performed to reveal that rPDCD5 was up-regulated in abiotic stress (low temperature and NaCl treatment).
