	1	Horizontal transfer and evolution of the biosynthetic gene cluster for benzoxazinoids in plants显示文摘Benzoxazinoids are a class of protective and allelopathic plant secondary metabolites that have been identified in multiple grass species and are encoded by the Bx biosynthetic gene cluster(BGC)in maize.Data mining of 41 high-quality grass genomes identified complete Bx clusters(containing genes Bx1–Bx5 and Bx8)in three genera(Zea,Echinochloa,and Dichanthelium)of Panicoideae and partial clusters in Triticeae.The Bx cluster probably originated from gene duplication and chromosomal translocation of native homologs of Bx genes.An ancient Bx cluster that included additional Bx genes(e.g.,Bx6)is presumed to have been present in ancestral Panicoideae.The ancient Bx cluster was putatively gained by the Triticeae ancestor via horizontal transfer(HT)from the ancestral Panicoideae and later separated into multiple segments on different chromosomes.Bx6 appears to have been under less constrained selection compared with the Bx cluster during the evolution of Panicoideae,as evidenced by the fact that it was translocated away from the Bx cluster in Zea mays,moved to other chromosomes in Echinochloa,and even lost in Dichanthelium.Further investigations indicate that purifying selection and polyploidization have shaped the evolutionary trajectory of Bx clusters in the grass family.This study provides the first candidate case of HT of a BGC between plants and sheds new light on the evolution of BGCs.
