Identification of the gene responsible for the excess boron tolerance in rice and its application to the breeding for excess boron tolerant rice

硼（B）是高等植物必需的微量营养元素，但过量的B会抑制作物的生长。在这项研究中，过量B耐性在水稻植物中进行了研究，我们确定了一个基因负责耐受B毒性，命名为BET 1。我们还培育了一个耐过量B的近等基因系的流行籼稻品种IR 64。

Boron(B) is an essential micronutrient for higher plants, but excess amounts of B inhibit growth of crops. In this study, excess B tolerance in rice plants was studied, and we identified a gene responsible for tolerance to B toxicity, named BET1. We also bred an excess B tolerant near-isogenic line of the popular indica cultivar IR64.
