Abstract The SNF1-related protein kinase 2 (SnRK2) family includes key regulators of osmostress and abscisic acid (ABA) responses in angiosperms can be classified into three subclasses. Subclass III SnRK2s act the ABA response while ABA-nonresponsive subclass I are regulated through osmostress. Here we report that an ancient SnRK2-based signalling module including upstream Raf-like (ARK) exclusively protects moss Physcomitrella patens from drought. both Arabidopsis semiterrestrial alga...
Given their sessile nature, land plants must use various mechanisms to manage dehydration under water-deficit conditions. Osmostress-induced activation of the SNF1-related protein kinase 2 (SnRK2) family elicits physiological responses such as stomatal closure protect during drought With plant hormone ABA receptors [PYR (pyrabactin resistance)/PYL resistance-like)/RCAR (regulatory component receptors) proteins] and group A phosphatases, subclass III SnRK2 also constitutes a core signaling...
Strigolactones (SLs) are a plant hormone inhibiting shoot branching/tillering and rhizospheric, chemical signal that triggers seed germination of the noxious root parasitic Striga mediates symbiosis with beneficial arbuscular mycorrhizal fungi. Identifying specific roles canonical noncanonical SLs, two SL subfamilies, is important for developing Striga-resistant cereals engineering architecture. Here, we report rice mutants lacking SLs do not show phenotypes known SL-deficient plants,...
Abscisic acid (ABA) controls seed dormancy and stomatal closure through binding to the intracellular receptor Pyrabactin resistance1 (Pyr1)/Pyr1-like/regulatory components of ABA receptors (PYR/PYL/RCAR) in angiosperms. Genes encoding PYR/PYL/RCAR are thought have arisen ancestor embryophytes, but roles genes nonvascular plants not been determined. In liverwort Marchantia polymorpha, reduces growth enhances desiccation tolerance increasing accumulation sugars various transcripts such as...
Abstract Bacterial phytopathogens, such as Pseudomonas syringae pv. tomato ( Pst ) DC3000, induce water-soaked lesions in the leaf apoplast under high humidity, facilitating infection. However, it remains largely unclear how plants regulate their resistance to restrict bacterial infection response humidity. Here, we demonstrate that abscisic acid (ABA)-catabolizing ABA 8’-hydroxylase, encoded by CYP707A3 , plays a critical role this Arabidopsis thaliana . Elevated humidity induces...
Summary Abscisic acid (ABA) and its signaling system are important for land plants to survive in terrestrial conditions. Here, we took a phosphoproteomic approach elucidate the ABA network Physcomitrella patens , model species of basal plants. Our analysis detected 4630 phosphopeptides from wild‐type P . two ABA‐responsive mutants, disruptant group‐A type‐2C protein phosphatase (PP2C; ppabi1a/b ) AR7, defective mutant ARK, identified as an upstream regulator SnRK2. Quantitative 143 The...
Abstract The plant hormones strigolactones (SLs) regulate shoot branching and mediate the communication with symbiotic mycorrhizal fungi, but also noxious root parasitic weeds, such as Striga spp. SLs derive from carlactone (CL) are divided structurally into canonical non-canonical SLs. However, questions about particular biological functions of two groups identification SL that inhibits still unanswered, hampering targeted modification pattern towards improving architecture resistance...
Moso bamboo (Phyllostachys edulis) is a typical East Asian that does not flower for > 60 years and propagates without seed reproduction. Thus, can be propagated vegetatively, possibly resulting in highly heterozygous genetic inheritance. Recently, draft genome of was reported, followed by whole single nucleotide polymorphisms (SNP) analysis, which showed the China has regional characteristics. Japan thought to have been introduced from over sea 1736. However, it unclear where how China....
Plants are often exposed not only to short-term (S) heat stress but also long-term (L) over several consecutive days. A few Arabidopsis mutants defective in L-heat tolerance have been identified, the molecular mechanisms involved less well understood than those S-heat tolerance. To elucidate mechanisms, we isolated new sensitive heat5 (sloh5) mutant from EMS-mutagenized seeds of L-heat-tolerant Col-0. The sloh5 was hypersensitive S-heat, osmo-shock, salt-shock or oxidative stress. causal...
Abstract Plants are often exposed not only to short-term (S-) heat stress but also diurnal long-term (L-) over several consecutive days. To reveal the mechanisms underlying L-heat tolerance, we here used a forward genetic screen for sensitive (sloh) mutants and isolated sloh4. The mutant was hypersensitive S-heat stress. causal gene of sloh4 identical MIP3 encoding member MAIGO2 (MAG2) tethering complex, which is composed MAG2, MIP1, MIP2 subunits localized at endoplasmic reticulum (ER)...
This study shows that ageing affects miRNA profiles in follicular fluid, and an is highly abundant the fluid of young cows supports growth oocytes derived from early antral follicles.We examined age-associated changes (FF) cows. The role miR-19b, which FF cows, vitro follicles (EAFs)-derived was assessed. collected (20-40 months) aged (>120 were similar between both age groups, whereas abundance some miRNAs differed these samples. granulosa cells (GCs) spent culture medium oocyte-GC...
Low-molecular-weight sugars serve as protectants for cellular membranes and macromolecules under the condition of dehydration caused by environmental stress such desiccation freezing. These also affect plant growth development provoking internal signaling pathways. We previously showed that both hormone abscisic acid (ABA) enhance tolerance gemma, a dormant propagule liverwort Marchantia polymorpha. To determine role ABA in sugar responses liverworts, we generated genome-editing lines M....
Phytohormone abscisic acid (ABA) plays a key role in stomata closure, osmostress acclimation, and vegetative embryonic dormancy. Group B3 Raf protein kinases (B3-Rafs) serve as positive regulators of ABA signaling the moss Physcomitrium patens angiosperm Arabidopsis thaliana . While P. has single B3-Raf called ARK, specific members B3-Rafs among six paralogs regulate A. , indicating functional diversification angiosperms. However, we found that liverwort Marchantia polymorpha belonging to...
SUMMARY The indole alkaloid gramine, 3‐(dimethylaminomethyl)indole, is a defensive specialized metabolite found in some barley cultivars. In its biosynthetic process, the tryptophan (Trp) side chain shortened by two carbon atoms to produce 3‐(aminomethyl)indole (AMI), which then methylated N ‐methyltransferase (HvNMT) gramine. Although shortening one of crucial scaffold formation steps alkaloids originating from aromatic amino acids, gene and enzyme involved Trp–AMI conversion reactions are...
Summary Only very limited information is available on why some nonsynonymous variants severely alter gene function while others have no effect. To identify the characteristic features of mutations that strongly influence function, this study focused SRK which encodes a highly polymorphic receptor kinase expressed in stigma papillary cells underlies female determinant self‐incompatibility Brassicaceae. A set 300 Arabidopsis thaliana transformants expressing mutated SRKb from A. lyrata was...
Abstract Locust bean (Ceratonia siliqua) accumulates the galactomannan (GM) locust gum (LBG) in its seeds. LBG is a major industrial raw material used as food thickener and gelling agent, whose unique properties mean that it cannot be readily replaced by other GMs. Whereas much known about GM accumulation genes associated with biosynthesis legumes, involved C. siliqua are largely unknown. Here, we present genome-wide list of predicted to pathway siliqua. We confirmed high endosperm using...
Although hormonal induction of parturition in cattle results the successful delivery healthy calves, risk retained fetal membrane is significantly increased. In a previous study, combination long-acting glucocorticoid, triamcinolone acetonide, with high dose betamethasone partially normalized placentomal gene expression during parturition; however, incidence remained high. This study further explored dysfunction and aimed to elucidate mechanism parturition-induced cows. this transcriptome...
