A method of measuring the mechanical properties of cells in living plant tissues in the direction of growth while simultaneously gathering confocal images reveals spatial gradients in extensibility.

Coordinated genetic and epigenetic differentiation of duplicate genes in ancient polyploids is common in genomes with and without biased fractionation.

Arabidopsis ALKBH10B is a major m⁶A mRNA demethylase affecting floral transition and vegetative growth.

Transcription factors CITF1 and SPL7 regulate the delivery of a micronutrient copper to anthers, thereby influencing fertility, and link copper homeostasis and the jasmonic acid metabolic pathway.

The production of regulatory membrane phospholipids required for polar tip growth of pollen tubes is controlled by mitogen-activated protein kinases.

The EIN3-PIF3 pair functions as a central integrator of multiple signals for the concerted repression of chloroplast development in soil.

The metal transporter NRAMP2 controls photosynthesis and antioxidant defenses by releasing manganese from the trans-Golgi network, thus building up a cytosolic pool that feeds downstream organelles.

Genome-wide analysis sheds light on the dependence of plastid translation on interactions between Shine-Dalgarno-like sequences in mRNA and the anti-Shine-Dalgarno sequence in 16S ribosomal RNA.

Mutations in Ectocarpus DISTAG, which encodes a TBCCd1 protein, disrupt the subcellular architecture in the germinating initial cell leading to loss of all basal structures from the developing alga.

A novel microtubule-associated protein is required for the pitted secondary cell wall patterning in xylem vessels.

ANXUR receptor-like kinases regulate two-tiered plant immunity by association with pattern recognition receptor and NLR protein complexes.

The coiled-coil and nucleotide binding domains of BROWN PLANTHOPPER RESISTANCE14 interact with WRKY transcription factors to activate defense signaling and confer resistance to planthopper attack.

The tomato DELLA protein PROCERA, a negative regulator of gibberellin signaling, increases the sensitivity of guard cells to abscisic acid, leading to stomatal closure and increased drought tolerance.

Natural variation in 347 Arabidopsis accessions reveals differential root plasticity responses to salinity, associated with 100 genetic loci, and roles for HKT1 and CYP79B2 in lateral root development.

Salt stress and Pol II-CTD phosphorylation status affect switching between normal snRNA/imRNA production and biogenesis of stress-specific mRNAs derived from 3′-elongated snRNAs/ncRNAs.

Detoxification of reactive carbonyl species produced by enhanced cellular sugar levels involves at least three subcellular compartments and depends on a specific glyoxalase I isoform during germination.

The number of phosphorylated sites on transcription factor SOG1 affects the strength of various DNA damage responses including DNA repair, replication arrest, cell death, and cell differentiation.

The effects of a semidominant MED5b mutant on phenylpropanoid metabolism and/or growth are suppressed by mutation of MED2, MED16, or MED23.
