新华社昆明2月25日电我国科学家研究发现,在水稻中高表达拟南芥WRKY57基因,能显著提高水稻对干旱和高盐胁迫的耐受性。该研究成果已于近日发表在国际期刊《植物科学前沿》上。干旱是限制农作物产量和品质的重要环境因素之一,然而国际上对于植物对干旱耐受性的潜在分子机制仍不清楚。据论文第一作者,中科院西双版纳热带植物园副研究员姜艳娟介绍,WRKY基因家族是一类典型的编码转录调控因子的基因家族,在“模式植物”拟南芥和水稻中分别拥有74个和102
Xinhua News Agency, Kunming, February 25 Research by our scientists found that high expression of Arabidopsis WRKY57 in rice can significantly increase the tolerance of rice to drought and high salt stress. The research results have been published recently in the international journal “Frontier of Plant Science”. Drought is one of the most important environmental factors that limit the yield and quality of crops. However, the potential molecular mechanism of plant tolerance to drought is still not clear internationally. According to the first author of the paper, Jiang Yanjuan, an associate researcher at the Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, the WRKY gene family is a typical gene family that encodes transcriptional regulatory factors, with 74 and 102
