Current Challenges in Studying Alternative Splicing in Plants: The Case of Physcomitrella patens SR Proteins.

ABSTRACT: To colonize different terrestrial habitats, early land plants had to overcome the challenge of coping with harsh new environments. Alternative splicing - an RNA processing mechanism through which splice sites are differentially recognized, originating multiple transcripts and potentially different proteins from the same gene - can be key for plant stress tolerance. Serine/arginine-rich (SR) proteins constitute an evolutionarily conserved family of major alternative splicing regulators that in plants subdivides into six subfamilies. Despite being well studied in animals and a few plant species, such as the model angiosperm Arabidopsis thaliana and the crop Oryza sativa, little is known of these splicing factors in early land plants. Establishing the whole complement of SR prot
