Alternative Splicing Control of Abiotic Stress Responses

Role of Aberrant Alternative Splicing in Cancer

Alternative splicing can alter genome sequence and as a consequence, many genes change to oncogenes. This event can also affect protein function and diversity. The growing number of study elucidate the pathological influence of impaired alternative splicing events on numerous disease including cancer. Here, we would like to highlight the significant role of alternative splicing in cancer biolog...

Abiotic Stress Signaling and Responses in Plants

As sessile organisms, plants must cope with abiotic stress such as soil salinity, drought, and extreme temperatures. Core stress-signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing. Stress signaling regulates proteins critical for ion and water transport and for metabolic and gene-express...

Abiotic Stress in Plants and Metabolic Responses

Differential regulation of transcript accumulation and alternative splicing of a DREB2 homolog under abiotic stress conditions in common wheat.

A number of cold responsive (Cor)/late embryogenesis abundant (Lea) genes are induced by both low temperature (LT) and dehydration. To understand the molecular basis of cold acclimation and its relationship with drought stress response in wheat seedlings, we isolated a DREB2 homolog Wdreb2, which is the candidate gene for a transcription factor of the Cor/Lea genes. The Wdreb2 expression was ac...

Alternative splicing at the intersection of biological timing, development, and stress responses.

High-throughput sequencing for transcript profiling in plants has revealed that alternative splicing (AS) affects a much higher proportion of the transcriptome than was previously assumed. AS is involved in most plant processes and is particularly prevalent in plants exposed to environmental stress. The identification of mutations in predicted splicing factors and spliceosomal proteins that aff...
