High-throughput RNA sequencing in crown tissue of barley sdw1 near-isogenic lines

This study's objective was to elucidate plant modifications and crown-specific transcriptome re-modeling that takes place in gibberellin-deficient barley sdw1 NILs exposed to increased temperatures. Experiments were designed to determine whether the phenotypic expression of sdw1 mutants is influenced by the allele-specific expression of the HvGA20ox2 gene or by wider genetic background variance and environmental cues. To achieve this goal, plants were examined considering phenotypic properties, physiological responses, and genomic constitution using high-throughput genotyping and sdw1 gene sequencing. We also employed the mRNA-seq method to acquire transcriptome-wide characterization of the crown tissue and provide new insights into the expression profiles of heat- and gibberellin-related genes.
