    Larger and more diverse SR protein families in the plant kingdom (e.g., 18 SR proteins in arabidopsis [75] versus only 12 in human [76]), resulting from genome amplification [77], could provide a plausible explanation for the occurrence of plant-specific functions, such as in the regulation of stress responses, for a subset of SR protein genes.
    • Alternative Splicing Control of Abiotic Stress Responses

      Alternative splicing, which generates multiple transcripts from the same gene, is an important modulator of gene expression that can increase proteome diversity and regulate mRNA levels. In plants, this post-transcriptional mechanism is markedly induced in response to environmental stress, and recent studies have identified alternative splicing events that allow rapid adjustment of the ...

    V stress cuja resposta é mediada pela hormona ABA. Este resultado preliminar sugere que o factor de splicing SR34 constitui um regulador negativo da resposta ao stress durante a germinação. Adicionalmente, por análise da localização subcelular das três isoformas de splicing da SR34, concluímos que o splicing alternativo deste gene não influencia a localização subcelular da proteína

    In fact, stress-associated genes are particularly prone to AS [32,33,34], which is markedly affected by abiotic stresses [32,35,36,37,38,39], and the expression/splicing pattern of several SR or SR-like proteins is stress-regulated [38,40,41,42], pointing to a crucial role for AS in plant responses to environmental stress.

    2.2. ABA Mediates Plant Development. The role of ABA in the growth and development of plants is also multi-faceted. ABA inhibits seed germination by promoting seed drying and dormancy [] and is involved in floral transition, lateral root formation, and seedling growth [].Studies have shown that at the seed maturity stage, the ABA content was higher in up-regulated ABA anabolic genes and at the ...

    Alternative splicing is the most significant mechanism responsible for the production of multiple protein isoforms from a single gene. The spliceosome, a large ribonucleoprotein complex, together … Modifications of the cellular proteome pool upon stress allow plants to tolerate environmental changes.

    Alternative splicing (AS) exists in eukaryotes to increase the complexity and adaptability of systems under biophysiological conditions by increasing transcriptional and protein diversity. As a classic hormone, abscisic acid (ABA) can effectively control plant growth, improve stress resistance, and …

    Notably, mounting evidence indicates that alternative splicing regulates stress responses largely by targeting the abscisic acid (ABA) pathway. We review here current understanding of post-transcriptional control of plant stress tolerance via alternative splicing and discuss research challenges for the near future.
  10. Serine/arginine-rich (SR) proteins are major modulators of alternative splicing, a key generator of proteomic diversity and flexible means of regulating gene expression likely to be crucial in plant environmental responses. Indeed, mounting evidence implicates splicing factors in signal transduction of the abscisic acid (ABA) phytohormone, which plays pivotal roles in the response to various ...
