近期,美国萨克生物学院在植物激素发出的信号中发现了一个重要的遗传机制,其可以使作物免受外界的胁迫,从而有利于解决人类的饥饿问题。科学家们发现了植物控制其对天然植物激素乙烯气体反应的遗传开关。这种气体反应在胁迫条件下会使叶片枯萎、早衰以及过熟而腐败。此项发表在2012年八月的《SCIENCE》杂志上的研究使得掌握控制植物乙烯开关的主要机制变成可能,使人们能够让作物在抗旱与生长之间得到平衡,因此减少干旱时的作物损失。
Recently, the American Sac Academy of Biology found an important genetic mechanism in the signals emitted by plant hormones, which can protect crops from external threats and help solve the problem of hunger in human beings. Scientists have discovered the genetic switch that plants control their response to the natural plant hormone ethylene gas. This gas response under stress conditions leaves the leaves withered, premature aging and over-ripening. The research, published in the August 2012 issue of SCIENCE, makes it possible to master the main mechanisms that control plant ethylene switching so that crops can be balanced between drought and growth, thus reducing crop losses during drought .
