Phylogenetic Analysis of Spliceosome SF3a2 in Different Plant Species.

The formation of mature mRNA requires cutting introns and splicing exons. The occurrence of splicing involves the participation of the spliceosome. Common spliceosomes mainly include five snRNPs: U1, U2, U4/U6, and U5. , an essential component of spliceosome U2 snRNP, participates in splicing a series of genes. There is no definition of in plants. The paper elaborated on from a series of plants through protein sequence similarity. We constructed the evolutionary relationship of in plants. Moreover, we analyzed the similarities and differences in gene structure, protein structure, the cis-element of the promoter, and expression pattern; we predicted their interacting proteins and constructed their collinearity. We have preliminarily analyzed in plants and clarified the evolutionary relationship between different species; these studies can better serve for in-depth research on the members of the spliceosome in plants.
