This study identifies genetic variation affecting tiller number and rate in barley, finding correlations with agronomic traits and QTL overlapping with days to heading and spike row-type.

The paper uses BSA-exome-seq to fine-map the ERA8 mutant in wheat to the TaMKK3-A locus, identifying a missense mutation linked to ABA hypersensitive germination.

This study uses RNA-seq to analyze allele-specific expression in barley hybrids, finding that cis-regulatory effects dominate over trans effects and are stable under cold stress.

The paper identifies a new leaf rust resistance gene, LrSyn137, in synthetic hexaploid wheat line Syn137 through cytogenetic and molecular mapping.

The paper shows that three yellow rust resistance genes in wheat are all encoded by the same locus Wtk1, but their resistance responses vary depending on genetic background.
