Although steroid hormones are important for animal development, the physiological role of plant steroids is unknown. The Arabidopsis DET2 gene encodes a protein that shares significant sequence identity with mammalian 5α-reductases. A mutation glutamate 204, which absolutely required activity human reductase, abolishes in vivo and leads to defects light-regulated development can be ameliorated by application steroid, brassinolide. Thus, may encode reductase brassinolide biosynthetic pathway,...
Brassinosteroids (BRs) are a class of steroid hormones essential for normal growth and development in plants. BR signaling involves the cell-surface receptor BRI1, glycogen synthase kinase-3-like kinase BIN2 as negative regulator, nuclear proteins BZR1 BZR2/BES1 positive regulators. The interactions among these components remain unclear. Here we report that BRs induce dephosphorylation accumulation protein. Experiments using proteasome inhibitor, MG132, suggest phosphorylation increases its...
GSK3/SHAGGY is a highly conserved serine/threonine kinase implicated in many signaling pathways eukaryotes. Although GSK3/SHAGGY-like kinases have been identified plants, little known about their functions plant growth and development. Here we show that the Arabidopsis BRASSINOSTEROID-INSENSITIVE 2 (BIN2) gene encodes kinase. Gain-of-function mutations within its coding sequence or overexpression inhibit brassinosteroid (BR) signaling, resulting plants resemble BR-deficient BR-response...
Plant steroid hormones, brassinosteroids (BRs), are perceived by the plasma membrane-localized leucine-rich-repeat-receptor kinase BRI1. Based on sequence similarity, we have identified three members of BRI1 family, named BRL1, BRL2 and BRL3. BRL1 BRL3, but not BRL2, encode functional BR receptors that bind brassinolide, most active BR, with high affinity. In agreement, only BRL3 can rescue bri1 mutants when expressed under control promoter. While is ubiquitously in growing cells, expression...
Significance Seed dormancy is a critical step in the lifecycle of plants, and it crucial to survival plant species; this process also important for agricultural practice prevent preharvest sprouting when humid conditions persist before harvest. This study uncovers previously unrecognized action auxin maintaining seed through AUXIN RESPONSE FACTOR 10/16-mediated expression ABSCISIC ACID INSENSITIVE 3 , key regulator abscisic acid-mediated dormancy.
An assay was developed to study plant receptor kinase activation and signaling mechanisms. The extracellular leucine-rich repeat (LRR) transmembrane domains of the Arabidopsis BRI1, which is implicated in brassinosteroid signaling, were fused serine/threonine domain XA21, rice disease resistance receptor. chimeric initiates defense responses cells upon treatment with brassinosteroids. These results, indicate that BRI1 perceives brassinosteroids, suggest a general mechanism for LRR kinases...
Abstract Brassinosteroid (BR) mutants of Arabidopsis have pleiotropic phenotypes and provide evidence that BRs function throughout the life plant from seedling development to senescence. Screens for BR signaling identified one locus, BRI1, which encodes a protein with homology leucine-rich repeat receptor serine (Ser)/threonine (Thr) kinases. Twenty-seven alleles this putative been isolated date, we present here identification molecular lesions 14 recessive represent five new mutations....
Abstract Electrochemical water splitting for H 2 production is limited by the sluggish anode oxygen evolution reaction (OER), thus using hydrazine oxidation (HzOR) to replace OER has received great attention. Here we report hierarchical porous nanosheet arrays with abundant Ni 3 N‐Co N heterointerfaces on foam superior hydrogen (HER) and HzOR activity, realizing working potentials of −43 −88 mV 10 mA cm −2 , respectively, achieving an industry‐level 1000 at 200 HzOR. The two‐electrode...
Global warming has profound effects on plant growth and fitness. Plants have evolved sophisticated epigenetic machinery to respond quickly heat, exhibit transgenerational memory of the heat-induced release post-transcriptional gene silencing (PTGS). However, how thermomemory is transmitted progeny physiological relevance are elusive. Here we show that HEAT SHOCK TRANSCRIPTION FACTOR A2 (HSFA2) directly activates H3K27me3 demethylase RELATIVE OF EARLY FLOWERING 6 (REF6), which in turn...
Super hybrid rice varieties with ideal plant architecture (IPA) have been critical in enhancing food security worldwide. However, the molecular mechanisms underlying their improved yield remain unclear. Here, we report identification of a QTL, qWS8/ipa1-2D, super Yongyou12 (YY12) and related varieties. In-depth genetic characterization qWS8/ipa1-2D reveals that this newly identified QTL results from three distal naturally occurring tandem repeats upstream IPA1, key gene/locus previously...
Under the requirements of China's strategic goal "carbon peaking and carbon neutrality", as a renewable, clean efficient secondary energy source, hydrogen benefits from abundant resources, wide variety sources, high combustion calorific value, non-polluting, various forms utilization, storage mediums good security, etc. It will become realistic way to help energy, transportation, petrochemical other fields achieve deep decarbonization, turn into an important replacement source for China...
Abstract GSK3 is a highly conserved kinase that negatively regulates many cellular processes by phosphorylating variety of protein substrates. BIN2 GSK3-like in Arabidopsis functions as negative regulator brassinosteroid (BR) signaling. It was proposed BR signals, perceived membrane receptor complex contains the leucine (Leu)-rich repeat receptor-like BRI1, inactivate to relieve its inhibitory effect on unknown downstream BR-signaling components. Using yeast (Saccharomyces cerevisiae)...
Abstract GLYCOGEN SYNTHASE KINASE3 (GSK3) is a highly conserved serine/threonine kinase involved in variety of developmental signaling processes. The Arabidopsis (Arabidopsis thaliana) genome encodes 10 GSK3-like kinases that are clustered into four groups. Forward genetic screens have so far uncovered eight mutants, all which carry gain-of-function mutations BRASSINOSTEROID-INSENSITIVE2 (BIN2), one the three members group II. Genetic and biochemical studies implicated negative regulatory...
The CLAVATA1 (CLV1) receptor kinase controls stem cell number and differentiation at the Arabidopsis shoot flower meristems. Other components of CLV1 signaling pathway include secreted putative ligand CLV3 receptor-like protein CLV2. We report evidence indicating that all intermediate strong clv1 alleles are dominant negative likely interfere with activity unknown kinase(s) have functional overlap CLV1. dominant-negative show major differences from characterized to date in animal systems,...
Endoplasmic reticulum-mediated quality control (ERQC) is a well-studied process in yeast and mammals that retains disposes misfolded/unassembled polypeptides. By contrast, how plants exert over their secretory proteins less clear. Here, we report mutated brassinosteroid receptor, bri1-5, carries Cys69Tyr mutation, retained the ER by an overvigilant ERQC system involving three different retention mechanisms. We demonstrate bri1-5 interacts with two chaperones, calnexin binding protein (BiP),...
Basic helix-loop-helix (bHLH) proteins are highly conserved transcription factors critical for cell proliferation and differentiation. Recent studies have implicated bHLH in many plant signaling processes, including brassinosteroid (BR) signaling. Here, we report identification of two families atypical capable modulating BR We found that activation-tagged bri1 suppressor 1-Dominant (atbs1-D), previously identified as a dominant weak receptor mutant bri1-301, was caused by overexpression...
Owing to their sessile nature, plants have evolved sophisticated genetic and epigenetic regulatory systems respond quickly reversibly daily seasonal temperature changes. However, our knowledge of how sense warming ambient temperatures is rather limited. Here we show that an increase in growth from 22 °C 30 effectively inhibited transgene-induced posttranscriptional gene silencing (PTGS) Arabidopsis . Interestingly, warmth-induced PTGS release exhibited transgenerational inheritance. We...
