Identification of CmbHLH Transcription Factor Family and Excavation of CmbHLHs Resistant to Necrotrophic Fungus Alternaria in Chrysanthemum.

ABSTRACT: Chrysanthemum morifolium Ramat. 'Huaihuang' is a traditional Chinese medicinal plant. However, a black spot disease caused by Alternaria sp., a typical necrotrophic fungus, has a serious damaging influence on the field growth, yield, and quality of the plant. 'Huaiju 2^#' being bred from 'Huaihuang', shows resistance to Alternaria sp. bHLH transcription factor has been widely studied because of their functions in growth development, signal transduction, and abiotic stress. However, the function of bHLH in biotic stress has rarely been studied. To characterize the resistance genes, the CmbHLH family was surveyed in 'Huaiju 2^#'. On the basis of the transcriptome database of 'Huaiju 2^#' after Alternaria sp. inoculation, with the aid
