To elucidate the molecular mechanisms underlying grain size formation in barley, this study selected two distinct barley cultivars with significant differences in grain dimensions: the large-grained cultivar ‘jianglinhuang’ and the small-grained cultivar ‘heiseyeqingke’. We conducted a comprehensive comparative analysis by integrating phenotypic measurements with RNA-seq data to elucidate molecular-level differences between ba...

Compared with other transcription factors, much less studies have been performed on paclobutrazol-resistance (PRE), a subgroup of the extensive bHLH transcription factor gene family, and the research in cotton was also limited. By utilizing the PRE genes and their conserved domains identified in Arabidopsis, a total of 23, 22, 11, and 12 PRE genes were identified from two major cultivated cotton species and their two ancestors...
