Title	Transcriptomic and proteomic analysis of alternative splicing in Physcomitrella patens moss
Description	Alternative splicing (AS) has a significant potential to impact on the eukaryotic cell transcriptome and proteome. However, the extent of this influence as well as mechanisms, providing the tissue-specific pattern of AS are poorly studied. Here, we analyzed the AS of two life forms, protonema and gametophores, as well as the protoplasts, of a model organism, the Physcomitrella patens moss, using the data of transcriptome and proteome profiling. Altogether, 12,043 genes subjected to alternative splicing were identified. The alternative splicing patterns of 302 genes involved in stress response, growth, and development are changed considerably in the process of the gametophore development, whereas AS of 276 genes involved in transcription regulation, development, cell interactions, and cell response to biotic and abiotic stresses altered upon protoplastitation. Using mass spectrometry analysis, we studied the extent to which AS contributes to proteome diversity and identified 117 isoform-specific peptides for 36 genes with AS events. Our results indicate that AS event have a little impact on the proteome diversity and mostly result in the addition of extra amino acids rather than editing of existing proteins sequences. Among differentially expressed and spliced genes we found serine/arginine-rich (SR) genes, which are known to regulate AS in cells. We identified new isoforms of these genes and data evidencing their translation were obtained at transcriptome and proteome level. We also found that treatment with abscisic and jasmonic acids led to the isoform-specific response in protonema. Besides, we revealed the potential lncRNA–mRNA and lncRNA–pre-mRNA interactions that can influence both the expression and alternative splicing of genes. It can point at an additional level of gene expression and AS regulation by non-coding transcripts in the Physcomitrella patens moss.
