Keeping roots water-tight The Casparian strip provides a waterproofing function to plant roots, protecting them against unregulated influxes of water and minerals. integrity the depends on receptor-like kinase. Doblas et al. Nakayama now identify peptide ligands in core root (the stele) that help regulate formation. receptor is expressed outward-facing surface endodermal cells surround stele. When layer sealed by strip, cannot reach their receptors. breached, whether damage or during...

Plants use leucine-rich repeat receptor kinases (LRR-RKs) to sense sequence diverse peptide hormones at the cell surface. A 3.0-Å crystal structure of LRR-RK GSO1/SGN3 regulating Casparian strip formation in endodermis reveals a large spiral-shaped ectodomain. The domain provides binding platform for 21 amino acid CIF ligands, which are tyrosine sulfated by tyrosylprotein sulfotransferase TPST/SGN2. harbors pocket sulfotyrosine and makes extended backbone interactions with CIF2. Quantitative...
The 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) enzyme catalyzes the major rate-limiting step of mevalonic acid (MVA) pathway from which sterols and other isoprenoids are synthesized. In contrast with our extensive knowledge regulation HMGR in yeast animals, little is known about this process plants. To identify regulatory components MVA plants, we performed a genetic screen for second-site suppressor mutations Arabidopsis thaliana highly drought-sensitive drought hypersensitive2 (dry2)...
TETRATRICOPEPTIDE THIOREDOXIN-LIKE (TTL) proteins are characterized by the presence of six tetratricopeptide repeats in conserved positions and a carboxyl-terminal region known as thioredoxin-like domain with homology to thioredoxins. In Arabidopsis (Arabidopsis thaliana), TTL gene family is composed four members, founder member, TTL1, required for osmotic stress tolerance. Analysis sequenced genomes indicates that genes specific land plants. this study, we report expression profiles using...
Summary Metallophytes constitute powerful models for the study of metal homeostasis, adaptation to extreme environments and evolution naturally selected traits. Arabidopsis halleri is a pseudometallophyte which shows constitutive zinc/cadmium (Zn/Cd) tolerance Zn hyperaccumulation but high intraspecific variability in Cd accumulation. To examine molecular basis variation accumulation, ionome, transcriptome cell wall glycan array profiles were compared two genetically close A. populations...
Increasing L-ascorbic acid (AsA, vitamin C) content in fruits is a common goal current breeding programs due to its beneficial effect on human health. Attempts increase AsA by genetic engineering have resulted variable success likely AsA's complex regulation. Here, we report the of ectopically expressing tomato D-galacturonate reductase (FaGalUR) gene from strawberry, involved biosynthesis, either under control constitutive 35S or fruit-specific polygalucturonase (PG) promoters. Although...

Abstract Production of reactive-oxygen species (ROS) by NADPH oxidases (NOXs) impacts many processes in animals and plants plant receptor pathways involve rapid, NOX-dependent increases ROS. Yet, their general reactivity has made it challenging to pinpoint the precise role direct cellular targets A well-understood ROS target are lignin peroxidases cell wall. Lignin can be deposited with exquisite spatial control, but underlying mechanisms have remained elusive. Here we establish a full...
Abstract In Arabidopsis (Arabidopsis thaliana (L.) Heynh), exposure to volatile compounds (VCs) emitted by Penicillium aurantiogriseum promotes root hair (RH) proliferation and hyper-elongation through mechanisms involving ethylene, auxin, photosynthesis signaling. addition, this treatment enhances the levels of small signaling peptide RAPID ALKALINIZATION FACTOR 22 (RALF22). Here, we used genetics address role RALF22 in fungal VC-promoted RH growth identify bioactive VC. We found that RHs...
Small signalling peptides (SSPs) play crucial roles in plant growth, development, and stress responses. However, accurately identifying characterising SSPs remains challenging due to their structural diversity the limitations of current prediction tools. Here, we introduce S 2 -PepAnalyst, a novel web tool designed enhance plants. By integrating comprehensive plant-specific datasets into machine learning model, -PepAnalyst offers versatility, improved accuracy 99.5% on average, reliability...
ABSTRACT RAPID ALKALINIZATION FACTOR (RALF) peptides are important players in regulating cell expansion. In Arabidopsis, volatile compounds (VCs) emitted by the fungal phytopathogen Penicillium aurantiogriseum promote root hair (RH) proliferation and hyper-elongation through ethylene enhanced photosynthesis signalling actions. A striking alteration proteome of VC-treated roots involves up-regulation RALF22. To test possible involvement RALF22 VC-promoted RH changes, we characterized density...
