The tms5 mutation exists in most current thermo-sensitive genic male sterility lines, which are essential in hybrid rice production. The Cao group has made an exciting new discovery: TMS5, as a phosphatase, removes 2′,3′-cyclic phosphate (cP) from cP-ΔCCA-tRNAs, enabling efficient tRNA repair.

tRNA 修复：水稻热敏雄性不育的关键

tms5突变存在于大多数当前热敏基因雄性不育品系中，这在杂交水稻生产中至关重要。Cao 小组取得了一项令人兴奋的新发现：TMS5 作为一种磷酸酶，可从 cP-ΔCCA-tRNA 中去除 2'，3'-环磷酸盐 （cP），从而实现高效的 tRNA 修复。
