High-light adaptation via ferredoxin-mediated tuning of the photosynthesis–photoprotection trade-off

Overexpression of Fd1 in tobacco plants adjusts the photosynthesis/photoprotection trade-off to enhance high-light adaptation.

Leaf variegation in a barley EMS mutant is controlled by two epistatic mutations

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

Inhibiting 2-oxoglutarate dehydrogenase reveals the mechanisms and limits of metabolic plasticity in developing maize kernels

This study investigates the role of 2-oxoglutarate dehydrogenase in maize kernels by knocking it down and analyzing metabolic changes and structural impacts.

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.

Single-nuclei sequencing of Moricandia arvensis reveals bundle sheath cell function in the photorespiratory shuttle of C3-C4 intermediate Brassicaceae

The paper uses single-nuclei RNA sequencing to study Moricandia arvensis, revealing bundle sheath cell-specific expression of photorespiration genes and associated pathways in a C3-C4 intermediate plant.

Kinetochore mutations and histone phosphorylation pattern changes preceded holo- and macro-monocentromere evolution

The paper compares centromere organization and (epi)genome features between two species with different centromere types, finding distinct histone phosphorylation patterns and kinetochore gene mutations.

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.

ATP-dependent Clp protease subunit C1, HvClpC1, is a strong candidate gene for barley variegation mutant luteostrians as revealed by genetic mapping and genomic re-sequencing

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

The paper identifies HvCMF3 as an essential gene for chloroplast development in barley through mutant analysis and phylogenetic studies.

Leaf Variegation and Impaired Chloroplast Development Caused by a Truncated CCT Domain gene in albostrians Barley

The paper identifies a mutation in the HvAST gene causing leaf variegation in barley by residual activity of a chloroplast-targeted CCT-domain protein.
