HDA19-mediated deacetylation of histone H3.3 lysine 27 and 36 regulates plant sensitivity to salt stress

This study identifies HDA19-mediated deacetylation of histone H3.3 lysine 27 and 36 as a regulator of plant salt stress tolerance through LEA protein accumulation.

A hidden T-DNA-linked inversion-duplication causes a pronounced light-dependent phenotype in Arabidopsis

The paper identifies a T-DNA-linked inversion-duplication in Arabidopsis that enhances gene expression and exacerbates a light-dependent phenotype in mdh1xme2 mutants.

Mitochondrial malate metabolism acts as a control hub for photosynthesis and carbon-nitrogen balance in Arabidopsis

This study shows that mitochondrial malate metabolism regulates photosynthesis and carbon-nitrogen balance in Arabidopsis under low-light conditions.

Arabidopsis root lipid droplets are hubs for membrane homeostasis under heat stress, and triterpenoid synthesis and storage.

This study investigates the role of lipid droplets in Arabidopsis root cells under heat stress, finding they act as hubs for membrane homeostasis, triterpenoid synthesis, and storage.

Immune priming in the insect gut: a dynamic response revealed by ultrastructural and transcriptomic changes

This paper investigates immune priming in the gut of Tribolium castaneum using RNA sequencing and transmission electron microscopy, showing that priming leads to gut damage, stress response, and gene upregulation that enhances protection against subsequent infection.

Copper resistance predicts heritable transgenerational fitness variation in the clonal duckweed Spirodela polyrhiza

The study shows that copper resistance predicts transgenerational fitness variation in Spirodela polyrhiza, with susceptible genotypes showing greater offspring stress response but increased resistance.

Advanced illumination-imaging reveals photosynthesis-triggered pH, ATP and NAD redox signatures across plant cell compartments

The paper uses advanced imaging to show photosynthesis affects pH, ATP, and NAD redox in plant cells beyond chloroplasts.

Regulation of Crassulacean Acid Metabolism at the protein level in the CAM plant Kalanchoë laxiflora

The paper shows CAM regulation in K. laxiflora involves more than transcript and protein abundance, including adaptive amino acid changes and phosphoproteome shifts between day and night.

Plant cells tolerate high rates of organellar mistranslation

This study shows plant cells tolerate high rates of organellar mistranslation, with plastids being more lenient than mitochondria, and reveals differences in stress responses.

DOG1 prevents AFPs activation by AHG1 to control dormancy separately from ABA core signaling

This study identifies DOG1's role in preventing AFPs activation by AHG1, controlling dormancy independently of ABA core signaling.

Plasma membrane H+-ATPase activation increases global transcript levels and promotes the shoot growth of light-grown Arabidopsis seedlings.

This study shows that PM H+-ATPase activation increases global transcript levels and promotes shoot growth in light-grown Arabidopsis by enhancing cell wall modification gene expression.

The major nucleoid-associated protein WHIRLY1 promotes chloroplast development in barley

This study characterizes the barley WHIRLY1 mutant, showing it promotes chloroplast development by remodeling nucleoids and coordinating protein expression, but is not essential for chloroplast biogenesis.
