Yet how such boundaries are formed, regulated and maintained and how these genes function in concert with additional floral-organ-specific genes to regulate flower development and growth remain largely unclear.Īlong with rapid improvements in sequencing technology, extensive molecular genetic analyses performed on a genome-wide scale have led to the identification of numerous key floral regulatory genes, suggesting that about one-quarter of the genes in the model plant Arabidopsis thaliana ( Arabidopsis) function in flower formation and development. Changing the boundaries of ABCDE gene expression usually leads to phenotypic variations in floral structures. The key feature of the ABCDE model is the boundaries or floral organ specificities of the floral organ identity genes (ABCDE-class genes), which specify the different floral organ types in a combinatorial manner. Based on their different homeotic functions in floral organogenesis, A class genes specify sepals identity, A + B + E genes specify petal identity, B + C + E genes specify stamen identity, C + E genes specify carpel identity and D genes specify ovule identity. According to this model, most genes involved in flower development belong to the MIKC C type of MADS-box gene family, with A, B, C/D, and E class genes corresponding to AP1 genes (derived from the AP1/ FUL clade), AP3/ PI genes (from the AP3/ PI clade), AG/ STK genes (from the AG clade), and SEP genes (from the SEP clade), respectively. The ABC model, latter updated as the ABCDE model or ‘quartet model’, defines the central features in the regulation of floral organogenesis and has provided guidance to studies of flower development and evolution for approximately 30 years. The flower, as a reproductive unit, represents a major innovation in plant development during angiosperm evolution, and playing a key role in Darwin's ‘abominable mystery’.
Finally, co-expression network analysis indicated that RcREM genes are co-expressed with a high proportion of key genes that regulate flowering time, floral organ development, and cell proliferation and expansion in R. Protein-protein interaction analysis indicated that RcREM14 interact with RcAP1 (one of the homology of A class genes in ABCDE model), highlighting the roles of RcREM genes in floral organ identity. Expression analysis revealed that most RcREM genes are specifically expressed in reproductive organs and that their specific expression patterns are dramatically altered in rose plants with mutations affecting floral organs. This family has been greatly expanded in rose ( Rosa chinensis) compared to other species, primarily through tandem duplication. Here, we performed genome-wide identification and evolutionary analysis of the REM gene family in Rosaceae. However, their evolution and their functional profiles in flower development remain poorly understood.
