Identification and Analysis of Phosphatidylethanolamine-Binding Protein Family Genes in the Hangzhou White Chrysanthemum (Chrysanthemum morifolium Ramat)

The Hangzhou White Chrysanthemum (Chrysanthemum morifolium Ramat) is one of the “Zhejiang eight flavors” in traditional Chinese medicine. phosphatidylethanolamine-binding protein (PEBP) plays an important role flowering and floral organ development. Even so, biological PEBPs has not been studied, which attracted us. Here, nine CmPEBP genes that contain PF01161 domain were identified for first time, their was preliminarily studied. A phylogenetic analysis classified into three subfamilies: MFT-like, TFL-like, FT-like genes. differential expression performed under different tissues stressors using qRT-PCR. It showed each displayed tissue-specific patterns. Expression patterns response to temperatures hormone investigated. They finally demonstrated be differentially expressed. TFL-like gene expression, delayed reproductive growth, upregulated heat stress. Conversely, low temperatures. CmFT1 could inhibited by GA (gibberellin), 6-BA (benzylaminopurine), ET (ethylene), MeSA (methyl salicylate) but activated IAA (indole-3-aceticacid), ABA (abscisic acid), SA (salicylic acid) dark, whereas CmFT2 CmFT3 levels ET, MeJA jasmonate), downregulated 6-BA, SA, MeSA. GA, IAA, CmTFL light dark treatments. Further research on better determine roles development, especially prolonged spraying exogenous hormones.
