Comparative Transcriptional Profiling and Physiological Responses of Two Contrasting Oat Genotypes under Salt Stress.

ABSTRACT: Salinity is one of the major abiotic factors that affect productivity in oat. Here, we report a comparison of the transcriptomes of two hexaploid oat cultivars, 'Hanyou-5' and 'Huazao-2', which differ with respect to salt tolerance, in seedlings exposed to salt stress. Analysis of the assembled unigenes from the osmotically stressed and control libraries of 'Hanyou-5' and 'Huazao-2' showed that the expression of 21.92% (36,462/166,326) of the assembled unigenes was differentially regulated in the two cultivars after different durations of salt stress. Bioinformatics analysis showed that the main functional categories enriched in these DEGs were "metabolic process", "response to stresses", "plant hormone signal transduction", "MAPK signalling", "oxidative phosphorylation", and the plant-pat
