The paper identifies two epistatic mutations causing leaf variegation in a barley mutant and proposes they impair chloroplast proteostasis.

This paper identifies Raw7 as a second gene controlling barley awn roughness, showing epistatic interaction with Raw1, and proposes a cytokinin signaling pathway mechanism.

The paper identifies CCR1 receptor-kinase as a negative regulator of cluster root and nodule development in white lupin, revealing a novel systemic pathway called AoDev that coordinates root organ development independently of symbiotic interactions.

This study presents a barley pangenome revealing structural variation linked to traits like disease resistance and plant architecture, highlighting its role in adaptive evolution.
