Evolution and Expression Patterns of the Fructose 1,6-Bisphosptase Gene Family in a Miracle Tree ().

() is a fast-growing tree species with tremendous economic and ecological value; the study of the key genes regulating photosynthesis and sugar accumulation is very important for the breeding of . Fructose 1,6-bisphosptase () gene has been found to play a key role in plant photosynthesis, sugar accumulation and other growth processes. However, no systemic analysis of has been reported in . A total of six genes were identifed and cloned based on the genome, and these genes were sorted into four groups. The characteristics of the gene family were analyzed such as phylogenetic relationships, gene structures, conserved motifs, and expression patterns. A element related to circadian control was first found in the promoter region of gene. Phylogenetic and quantitative real-time PCR analyses showed that and may be chloroplast type 1 and cytoplasmic , respectively. FBP proteins from and 22 other plant species were used for phylogenetic analyses, indicating that family may have expanded during the evolution of algae to mosses and differentiated cpFBPase1 proteins in mosses. This work analyzes the internal relationship between the evolution and expression of the six , providing a scientific basis for the evolutionary pattern of plant , and promoting the functional studies of genes.
