Cytokinin regulates the gravitropic setpoint angle of seminal roots in barley and wheat

This study identifies cytokinin as a regulator of gravitropic setpoint angles in seminal roots of barley and wheat through transcriptomic and functional analyses.

BpLAZY1A Mediates Transcriptional Polarity and Drives Adaxial Tension Wood Like Tissue Formation in Silver Birch (Betula pendula) Branches

This paper identifies BpLAZY1A as a key gene regulating gravitropic signaling and tissue polarity in silver birch branches, linking gene expression asymmetry to biomechanical reinforcement and growth orientation.

Root growth promotion by Penicillium melinii: mechanistic insights and agricultural applications

This study shows Penicillium melinii promotes root growth and plant biomass across species and environments, enhancing yield in tomato field trials through auxin signaling and subtle molecular interactions.

Wild rice Oryza rufipogon outperforms cultivated rice in stimulating beneficial bacterial endophytes.

This study compares how root exudates from wild and cultivated rice affect bacterial endophytes, finding that wild rice promotes more beneficial microbial interactions.

Comprehensive characterisation of IAA inactivation pathways reveals the impact of glycosylation on auxin metabolism and plant development

The paper characterizes IAA inactivation pathways, showing glycosylation's role in modulating IAA levels and plant development through genetic and metabolic analyses.

The CYP71A, NIT, AMI, and IAMH gene families are dispensable for indole-3-acetaldoxime-mediated auxin biosynthesis in Arabidopsis

This study shows that gene families involved in the IAOx pathway are not essential for auxin biosynthesis in Arabidopsis, challenging the proposed linear pathway and suggesting an uncharacterized route.

Ca2+ signature gates early auxin signaling in Arabidopsis roots

The paper uses optogenetics to show that Ca2+ signals regulate early auxin signaling in Arabidopsis roots, affecting growth and transcriptional responses.

Enhanced auxin signaling hub triggers root hair growth at moderate low temperature in Arabidopsis thaliana

Integration of multi-omics and deep phenotyping provides novel insights into multiple abiotic stress responses in potato

The paper integrates multi-omics and phenotyping data to identify molecular signatures of potato responses to abiotic stresses.

Phenylacetic acid metabolism in land plants: novel pathways and metabolites

This study identifies four novel PAA metabolites in land plants and shows PAA and IAA share metabolic pathways, suggesting complex auxin regulation.

The Draparnaldia genome: alternative mechanisms for multicellularity and terrestrialization in green plants

This study sequenced the Draparnaldia genome and transcriptomes, revealing expanded gene families linked to multicellularity and terrestrial adaptations, and its ability to synthesize phytohormones used by land plants.
