Base editing of EIF4E creates novel resistance alleles against bymoviruses in winter barley

This study uses base editing to create novel resistance alleles in barley against bymoviruses, showing two alleles confer resistance without yield loss.

Rate of meristem initiation driven by the MADS-WUS axis contributes to floral survival and inflorescence evolution in grasses

This study shows that the MADS-WUS axis regulates floral initiation rates in barley, influencing inflorescence architecture and reproductive strategies through allele selection and duplication.

Programmed chromosome elimination correlates with the overexpression of cohesin and additional B chromosome-encoded genes in Aegilops speltoides

The paper identifies genes and mechanisms involved in programmed chromosome elimination in Aegilops speltoides, focusing on B chromosome-encoded cohesin and centromere-related factors.

Generation and characterization of a barley strigolactone mutant collection: from plant architecture to drought stress response

This study characterizes barley strigolactone mutants to explore their roles in plant architecture and drought stress response, finding functional differences in biosynthesis and signaling pathways.

Epistatic interaction of the genes Raw1 and Raw7 controls barb size and frequency in barley awn roughness

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

Hypermorphic TaARF4 shapes wheat architecture by repressing SPL-mediated developmental timing

This study identifies a hypermorphic mutation in TaARF4-A2 that represses SPL-mediated developmental timing, leading to altered wheat architecture by promoting aerial branching and reducing reproductive development.

FLOWERING LOCUS T1 is a pleiotropic regulator of reproductive development, plant longevity, and source-sink relations in barley

This study shows FT1 regulates source-sink interactions, plant longevity, and reproductive development in barley by affecting meristem determinacy and metabolic pathways.

HvbZIP33 and HvbZIP76 have overlapping roles in foliar transpiration in drought-stressed barley

This study identifies HvbZIP33 and HvbZIP76 as key regulators of transpiration in drought-stressed barley, showing their role in maintaining water use efficiency.

Barley resistance and susceptibility to fungal cell entry involve the interplay of ROP signaling with phosphatidylinositol-monophosphates

This study identifies RACB interaction partners in barley-Bh pathosystem and shows their roles in disease resistance or susceptibility through lipid interactions.

Adaptive diversification through structural variation in barley

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

Mutation of the ALBOSTRIANS Ohnologous Gene HvCMF3 Impairs Chloroplast Development and Thylakoid Architecture in Barley due to Reduced Plastid Translation
