Special Issue Information

Dear Colleagues,

Alternative RNA splicing is a crucial step for expressing information encoded in plant genomes, and regulates plant development and abiotic stress responses.

Abiotic stresses such as salt, drought, heat, cold and hypoxia markedly alter splicing patterns in plants. These alternative splicing events implement changes in gene expression for adaptive responses to adverse environments. In addition, alternative splicing regulates plant developmental processes by generating different alternative splice variants. However, the precise regulatory mechanism of alternative splicing in plant development and abiotic stress responses remains to be understood.

This Special Issue will focus on findings relating to the regulatory mechanisms underlying plant development and abiotic stress responses via alternative splicing. The submission of work reporting the molecular mechanisms of alternative splicing in plant development and abiotic stress signal transduction is especially encouraged. Notwithstanding, contributions on other related topics to understand the regulatory mechanisms of alternative splicing in plants are also welcomed, including reviews and original research articles.

Abstract
Anthocyanin synthetase (ANS), a key enzyme in the final step of the anthocyanin synthesis pathway, catalyzes the conversion of leucoanthocyanidins to anthocyanins. In this study, an ANS structural protein (TRINITY_DN18024_c0_g1) was found to be associated with anthocyanin accumulation in Acer pseudosieboldianum leaves, named [...] Read more.
Anthocyanin synthetase (ANS), a key enzyme in the final step of the anthocyanin synthesis pathway, catalyzes the conversion of leucoanthocyanidins to anthocyanins. In this study, an ANS structural protein (TRINITY_DN18024_c0_g1) was found to be associated with anthocyanin accumulation in Acer pseudosieboldianum leaves, named ApsANS. Real-time quantitative fluorescence PCR analysis revealed that the expression of ApsANS was significantly higher in red-leaved (variant) than green-leaved (wild-type) strains, which was consistent with the transcriptome data. The UPLC results showed that the cyanidin metabolites may be the key substance influencing the final color formation of Acer pseudosieboldianum. The ApsANS gene was cloned and analyzed through bioinformatics analysis. ApsANS has a total length of 1371 bp, and it encodes 360 amino acids. Analysis of the structural domain of the ApsANS protein revealed that ApsANS contains a PcbC functional domain. Protein secondary structure predictions indicate that α-helix, irregularly coiled, and extended chains are the major building blocks. Subcellular localization predicted that ApsANS might be localized in the nucleus. The phylogenetic tree revealed that ApsANS is relatively closely related to ApANS in Acer palmatum. The prediction of miRNA showed that the ApsANS gene is regulated by miR6200. This study provides a theoretical reference for further analyzing the regulatory mechanism of leaf color formation in Acer pseudosieboldianum. Full article

The alternative splicing of pre-mRNA generates distinct mRNA variants from a pre-mRNA, thereby modulating a gene’s function. The splicing of pre-mRNA depends on splice sites and regulatory elements in pre-mRNA, as well as the snRNA and proteins that recognize these sequences. Among these, RNA-binding proteins (RBPs) are the primary regulators of pre-mRNA splicing and play a critical role in the regulation of alternative splicing by recognizing the elements in pre-mRNA. However, little is known about the function of RBPs in stress response in plants. Here, we summarized the RBPs involved in the alternative splicing of pre-mRNA and their recognizing elements in pre-mRNA, and the recent advance in the role of RBP-mediated alternative splicing in response to abiotic stresses in plants. This review proposes that the regulation of pre-mRNA alternative splicing by RBPs is an important way for plants to adapt to abiotic stresses, and the regulation of alternative splicing by RBPs is a promising direction for crop breeding.
