禾本科牧草是畜牧业重要的饲料来源,同时在生态保护方面发挥积极作用,而干旱是影响禾本科牧草产量的重要非生物胁迫因子。20世纪九十年代以后,禾本科牧草抗旱基因工程发展迅速。本综述总结了国内外禾本科牧草抗旱研究的相关报道,从抗旱相关基因的克隆,植株再生体系建立,遗传转化方法,转抗旱基因禾本科牧草四个方面对禾本科牧草抗旱基因工程进行了论述,总结了禾本科牧草抗旱基因工程的研究现状,并对提高禾本科牧草抗旱基因工程效率提出了建议。
Grasses are an important feed source for livestock husbandry and play an active role in ecological protection. Drought is an important abiotic stress factor that affects gramineous herbage production. Since the 1990s, gramineous grass drought-tolerant genetic engineering is developing rapidly. This review summarizes reports of grassland drought resistance research both at home and abroad. The drought resistance gene engineering of gramineous pasture has been discussed in four aspects: cloning of drought-related genes, establishment of plant regeneration system, genetic transformation methods and transgenic gramineous pasture , Summed up the grazing pasture drought resistance genetic engineering research status, and improve the gramineous pasture drought resistance gene engineering recommendations.
