Capsicum annuum basic transcription factor 3 (CaBtf3) regulates transcription of pathogenesis-related genes during hypersensitive response upon Tobacco mosaic virus infection

► CaBtf3 might regulate HR lesion formation. ► CaBtf3 could contribute to the HR cell death as a positive regulator. ► CaBtf3 could function as a transcription factor in the nucleus by transcriptional regulation of HR-related gene expression.
