ZmVPS37A is a domestication gene involved in pathogen defense. (A) Fst (upper) and π (lower) values in teosinte and landrace across the 0.18-Mb genomic region surrounding the ZmVPS37A gene, which is indicated by the purple bar. (B) The stalk phenotypes of teosinte, 303WX, and B73 seedlings 7 days after inoculation by Fusarium graminearum PH-1. (C) Gene expression analysis of ZmVPS37A responding to F. graminearum PH-1 48 h after infection. Values are mean ± s.d. Significant differences are shown by different letters (p < 0.05).
