One Gene, Many Proteins: Mapping Cell-Specific Alternative Splicing in Plants.

Pre-mRNA alternative splicing (AS) generates protein variants from a single gene that can create novel regulatory opportunities. In this issue of Developmental Cell , Li et al. (2016) present a high-resolution expression map of AS events in Arabidopsis root tissues, giving insight into cell-type- and stage-specific AS mechanisms in plants. [ABSTRACT FROM AUTHOR]
