Genome-wide identification and functional analysis of the splicing component SYF2/NTC31/p29 across different plant species.

This study systematically identifies plant SYF2/NTC31/p29 genes from 62 plant species by a combinatory bioinformatics approach, revealing the importance of this gene family in phylogenetics, duplication, transcriptional, and post-transcriptional regulation. Alternative splicing is a post-transcriptional regulatory mechanism, which is critical for plant development and stress responses. The entire process is strictly attenuated by a complex of splicing-related proteins, designated splicing factors.
