摘　　要：Dear editor,In the 1960s,the use of semi-dwarf rice and wheat varieties ushered in the‘‘Green Revolution,’’leading to reduced lodging and increased harvest index.In rice,essentially all modern semidwarf varieties carry a specific null mutation or weak alleles of Semi-Dwarf1(SD1),which encodes a GA20-2 oxidase in the gibberellin biosynthetic pathway(Monna et al.,2002;Sasaki et al.,2002;Spielmeyer et al.,2002).In addition to gibberellins,other plant hormones such as brassinosteroids,strigolactones,and auxin also function in reducing rice height(Ferrero-Serrano et al.,2019).However,many dwarf or semi-dwarf mutants have not been widely used in rice-breeding programs because they adversely impact grain yield(Ferrero-Serrano et al.,2019).
