Upregulation of the AT-hook DNA binding gene BoMF2 in OguCMS anthers of Brassica oleracea suggests that it encodes a transcriptional regulatory factor for anther development.

Abstract excerpt

Ogura cytoplasmic male sterility (OguCMS) is the most important CMS system used for F1 hybrid cabbage production worldwide. The anther abortion and defective pollen development exhibited in OguCMS are coordinately regulated by the mitochondrial male sterile gene orf138 and many nuclear transcriptional regulatory factors. AT-hook DNA binding proteins regulate cell-specific gene expression. In this study, we cloned...
