- 摘要:
- 为研究大豆细胞壁脯氨酸富集蛋白基因在非生物胁迫下发挥的作用,利用实时荧光定量PCR,对大豆中的两个脯氨酸富集蛋白基因SbPRP1和SbPRP2在非生物胁迫下的表达情况进行检测。结果显示:SbPRP1在高盐和低温处理下表达量下降,分别在处理后1 和24 h达到最低值;在模拟干旱处理下表达量先下降后升高,处理后24 h达到最大值。SbPRP2在高盐、模拟干旱和低温处理下表达量均有所升高,分别在处理后24,1 和5 h达到最大值。表明SbPRP1和SbPRP2可能参与了大豆对不利环境的适应性调控。通过RT-PCR从大豆叶片中扩增SbPRP1和SbPRP2的基因全序列并构建到植物表达载体pRI101-AN上。
- Abstract:
- Plant proline-rich proteins (PRPs) are putative cell wall proteins, which are usually associated with abiotic stress. The expression of SbPRP1 and SbPRP2 under abiotic stress treatments in soybean was detected by real-time fluorescence quantitative PCR. The expression of SbPRP1 was decreased under salt and cold treatments, reaching the minimum expression at 1 and 24 h, respectively. While it increased firstly and thereafter declined under simulated drought treatment, reaching the maximum expression at 24 h. The expression of SbPRP2 was increased under salt, simulated drought and cold treatments, reaching the maximum expression at 24, 1 and 5 h, respectively. These results indicate that SbPRP1 and SbPRP2 may involve in the regulation of adapting to adverse environment in soybean. The SbPRP1 and SbPRP2 were amplified through RT-PCR from soybean leaves and constructed to plant expression vector of pRI101-AN.
