Mitochondrial genes are involved in the fertility transformation of the thermosensitive male-sterile line YS3038 in wheat.

ABSTRACT: Heterosis can improve the stress resistance, quality, and yield of crops, and the male sterility of wheat can be utilized to accelerate the breeding process of hybrid. To determine whether mitochondrial genes are involved in the fertility of K-type cytoplasmic male-sterile (CMS) line and the YS-type thermosensitive male-sterile (TMS) line in wheat, we sequenced and assembled the mitochondrial genomes of K519A, 519B, and YS3038 by next-generation sequencing (NGS). The non-synonymous mutations were analyzed, and the first-generation sequencing was conducted to verify the non-synonymous mutation sites. Furthermore, the expression patterns of genes with non-synonymous mutations were analyzed. Finally, the candidate genes were silenced by barley stripe mosaic virus-induced gene silencing (BSMV-
