Plants, like animals, are exposed to abiotic and biotic stresses which inhibit their growth and development. Alternative splicing plays a crucial role in plant response to biotic stress, although the exact mechanisms are still unclear. The importance of alternative splicing in plant immunity has been established.
Plants, like animals, are constantly exposed to abiotic and biotic stresses, which often inhibit plant growth and development, and cause tissue damage, disease, and even plant death. Efficient and timely response to stress requires appropriate co- and posttranscriptional reprogramming of gene expression. Alternative pre-mRNA splicing provides an important layer of this regulation by controlling the level of factors involved in stress response and generating additional protein isoforms with specific features. Recent high-throughput studies have revealed that several defence genes undergo alternative splicing that is often affected by pathogen infection. Despite extensive work, the exact mechanisms underlying these relationships are still unclear, but the contribution of alternative protein isoforms to the defence response and the role of regulatory factors, including components of the splicing machinery, have been established. Modulation of gene expression in response to stress includes alternative splicing, chromatin remodelling, histone modifications, and nucleosome occupancy. How these processes affect plant immunity is mostly unknown, but these facets open new regulatory possibilities. Here we provide an overview of the current state of knowledge and recent findings regarding the growing importance of alternative splicing in plant response to biotic stress.
