Splicing is important for regulation of gene expression programmes, including those involved in plant development or plant environmental responses. In our study, we report that GRP20 regulates Arabidopsis gene expression by ensuring the proper splicing of thousands of floral and leaf RNAs, including the retention of micro exons in conserved floral homeotic genes. GRP20 binds to RNAs and interacts with the spliceosome, and both events are required for normal splicing and flower development.
