Two transposable element insertions are causative mutations for the major domestication gene teosinte branched 1 in modern maize

摘要：

Dear Editor, Transposable elements (TEs) have long been regarded as genomic parasites and occupy a significant portion of eukaryotic genomes because of their massive replication in host genomes.However, at times, TEs can also be domesticated by genes and thereby contribute new regulatory functions to genes ”1, 2”.Here we show that two TE insertions in a distant upstream region of tbl are the causative mutations in the teosinte branched 1 (tb1)gene that account for the gene”s role in the domestication of modem com from its ancestor teosinte.
