Genomic architecture and functional relationships of intronless, constitutively- and alternatively-spliced genes in Brachypodium distachyon

What is it about?

In this study, we analyzed influence of genomic attributes on splicing incidence, frequency, as well as functional relationships among spliced and non-spliced genes on a genome-wide scale in Brachypodium.

Why is it important?

Our findings provided new insights into splicing regulation and its functional relevance to plant cellular processes. For example, we found that exon length negatively constrains splicing occurrence, suggesting that exon splicing signals are also important regulators of pre-mRNA splicing in plants.
