Sequestration of AUXIN RESPONSE FACTOR (ARF) transcription factors in cytoplasmic condensates represents a specialized mechanism for modulating cellular auxin responsiveness. In this issue of Developmental Cell, Xuan et al. show that MULTIPLE C2-DOMAIN AND TRANSMEMBRANE REGION PROTEIN (MCTP) proteins stimulate lateral root development by antagonizing ARF7 and ARF19 condensation.

Azospirillum argentinense Az19 is an osmotolerant plant growth-promoting bacterium that protects maize plants from drought. In this work, we explored the role of trehalose in the superior performance of Az19 under stress. The trehalase-coding gene treF was constitutively expressed in Az19 through a miniTn7 system.

Pre-harvest sprouting (PHS) in groundnut leads to substantial yield losses and reduced seed quality, resulting in reduced market value of groundnuts. Breeding cultivars with 14-21 days of fresh seed dormancy (FSD) holds promise for precisely mitigating the yield and quality deterioration. In view of this, six multi-locus genome-wide association study (ML-GWAS) models alongside a single-locus GWAS (SL-GWAS) model were employed on a groundnut mini-core collection using multi season phenotyping and 58 K "Axiom_Arachis" array genotyping data.

DNA methylation repatterning is an epigenomic component of plant stress response, but the extent that methylome data can elucidate changes in plant growth following stress onset is not known. We applied high-resolution DNA methylation analysis to decode plant responses to short- and long-term high light stress and, integrating with gene expression data, attempted to predict components of plant growth response. We identified 105 differentially methylated genes (DMGs) following 1 h of high light treatment and 193 DMGs following 1 week of intermittent high light treatment.

Lead (Pb) pollution in soil affects growth of plants. Plants' endogenous hormones play an important role in resistance to Pb of plant. In order to explore the hormone-based mechanisms of Pb accumulationin in hyperaccumulator , a pot experiment was conducted to analyze the contents of endogenous hormones (auxin, gibberellin, abscisic acid, and cytokinin) and related genes expressions, and Pb contents of , as well as the transporter (cation exchangers (CAX), heavy metal ATPases (HMA), and ATP-binding cassette (ABC)) concentrations under foliar spraying of indoleacetic acid (IAA).
