Comparative transcriptomic analysis reveals divergent photosynthetic gene regulation under salinity in contrasting barley varieties, highlighting target pathways for breeding resilient crops.
, were induced only in Boulifa. By contrast, several genes associated with photosystems I and II, and light receptor chlorophylls A and B, were more repressed in Testour. Co-expression network analysis identified specific gene modules correlating with differences in genotypes and morpho-physiological traits. Overall, salinity-induced differential transcript accumulation underlies the differential morpho-physiological response in both genotypes and could be important for breeding salt tolerance in barley.
