The coi1 mutation defines an Arabidopsis gene required for response to jasmonates, which regulate defense against insects and pathogens, wound healing, pollen fertility. wild-type allele, COI1 , was mapped a 90-kilobase genomic fragment located by complementation of coi1-1 mutants. predicted amino acid sequence the protein contains 16 leucine-rich repeats F-box motif. It has similarity proteins TIR1, human Skp2, yeast Grr1, appear function targeting repressor removal ubiquitination.
Abstract Jasmonates (JAs) mediate plant responses to insect attack, wounding, pathogen infection, stress, and UV damage regulate fertility, anthocyanin accumulation, trichome formation, many other developmental processes. Arabidopsis thaliana Jasmonate ZIM-domain (JAZ) proteins, substrates of the CORONATINE INSENSITIVE1 (COI1)–based SCFCOI1 complex, negatively these responses. Little is known about molecular mechanism for JA regulation accumulation initiation. In this study, we revealed that...
Abstract Jasmonates play a number of diverse roles in plant defense and development. CORONATINE INSENSITIVE1 (COI1), an F-box protein essential for all the jasmonate responses, interacts with multiple proteins to form SCFCOI1 E3 ubiquitin ligase complex recruits ZIM-domain (JAZ) degradation by 26S proteasome. To determine which directly binds jasmonoyl-isoleucine (JA-Ile)/coronatine (COR) serves as receptor jasmonate, we built high-quality structural model COI1 performed molecular modeling...
Xie and colleagues previously isolated the Arabidopsis COI1 gene that is required for response to jasmonates (JAs), which regulate root growth, pollen fertility, wound healing, defense against insects pathogens. In this study, we demonstrate associates physically with AtCUL1, AtRbx1, either of Skp1-like proteins ASK1 or ASK2 assemble ubiquitin-ligase complexes, have designated SCFCOI1. COI1E22A, a single amino acid substitution in F-box motif COI1, abolishes formation SCFCOI1 complexes...
Abstract The Arabidopsis thaliana F-box protein CORONATINE INSENSITIVE1 (COI1) perceives jasmonate (JA) signals and subsequently targets the Jasmonate-ZIM domain proteins (JAZs) for degradation by SCFCOI1-26S proteasome pathway to mediate various jasmonate-regulated processes, including fertility, root growth, anthocyanin accumulation, senescence, defense. In this study, we screened JAZ-interacting from an cDNA library in yeast two-hybrid system. MYB21 MYB24, two R2R3-MYB transcription...
Summary Jasmonates (JAs) regulate Arabidopsis thaliana wound and defence responses, pollen development, stress‐related growth inhibition. Significantly, each of these responses requires COI1, an F‐box protein. Other proteins interact with SKP1 cullin to form SCF complexes that selectively recruit regulatory targeted for ubiquitination. To determine whether COI1 also functions in complex, we have characterized bind COI1. An cDNA expression library was screened yeast clones produce which can...
Precise coordination between stamen and pistil development is essential to make a fertile flower. Mutations impairing filament elongation, pollen maturation, or anther dehiscence will cause male sterility. Deficiency in plant hormone gibberellin (GA) causes sterility due accumulation of DELLA proteins, GA triggers degradation promote development. jasmonate (JA) also However, little known about the relationship JA controlling Here, we show that MYB21, MYB24, MYB57 are GA-dependent...
Abstract Plants have evolved sophisticated mechanisms for integration of endogenous and exogenous signals to adapt the changing environment. Both phytohormones jasmonate (JA) ethylene (ET) regulate plant growth, development, defense. In addition synergistic regulation root hair development resistance necrotrophic fungi, JA ET act antagonistically gene expression, apical hook curvature, defense against insect attack. However, molecular mechanism such antagonism between signaling remains...
Summary A critical step during rice ( Oryza sativa ) cultivation is dense planting: a wider tiller angle will increase leaf shade and decrease photosynthesis efficiency, whereas narrower makes for more efficient plant architecture. The molecular basis of remains unknown. This research demonstrates that controlled by major quantitative trait locus, TAC1 Tiller Angle Control 1 ). was mapped to 35‐kb region on chromosome 9 using large F 2 population from crosses between an indica rice, IR24,...
In plants, basic leucine zipper (bZIP) proteins regulate numerous biological processes such as seed maturation, flower and vascular development, stress signalling pathogen defence. We have carried out a genome-wide identification analysis of 125 bZIP genes that exist in the maize genome, encoding 170 distinct proteins. This family can be divided into 11 groups according to phylogenetic relationship among those Arabidopsis rice. Six kinds intron patterns (a–f) within hinge regions are...
Abstract Stamens are the plant male reproductive organs essential for fertility. Proper development of stamens is modulated by environmental cues and endogenous hormone signals. Deficiencies in biosynthesis or perception phytohormone jasmonate (JA) attenuate stamen development, disrupt fertility, abolish seed production Arabidopsis thaliana. This study revealed that JA-mediated regulated a bHLH-MYB complex. The IIIe basic helix-loop-helix (bHLH) transcription factor MYC5 acts as target JAZ...
Plants have evolved sophisticated systems for adaptation to their natural habitat. In response developmental and environmental cues, plants produce perceive jasmonate (JA) signals, which induce degradation of JASMONATE-ZIM-Domain (JAZ) proteins derepress the JAZ-repressed transcription factors regulate diverse aspects defense responses processes. Here, we identified bHLH subgroup IIId (bHLH3, bHLH13, bHLH14 bHLH17) as novel targets JAZs. These act repressors function redundantly negatively...
The WRKY transcription factors function in plant growth and development, response to the biotic abiotic stresses. Although many studies have focused on functional identification of factors, much less is known about molecular phylogenetic global expression analysis complete family maize. In this study, we identified 136 proteins coded by 119 genes B73 inbred line from genome named them an orderly manner. Then, a comprehensive five species was performed explore origin evolutionary patterns...
Plants initiate leaf senescence to relocate nutrients and energy from aging leaves developing tissues or storage organs for growth, reproduction, defense. Leaf senescence, the final stage of development, is regulated by various environmental stresses, developmental cues, endogenous hormone signals. Jasmonate (JA), a lipid-derived phytohormone essential plant defense serves as an important signal activate senescence-associated gene expression induce senescence. This study revealed one...
Abstract Integration of diverse environmental and endogenous signals to coordinately regulate growth, development, defense is essential for plants survive in their natural habitat. The hormonal gibberellin (GA) jasmonate (JA) antagonistically synergistically aspects plant defense. GA JA induce initiation trichomes, which assist seed dispersal act as barriers protect against insect attack, pathogen infection, excessive water loss, UV irradiation. However, the molecular mechanism underlying...
Paclitaxel is a well known anticancer compound. Its biosynthesis involves the formation of highly functionalized diterpenoid core skeleton (baccatin III) and subsequent assembly phenylisoserinoyl side chain. Despite intensive investigation for half century, complete biosynthetic pathway baccatin III remains unknown. In this work, we identified bifunctional cytochrome P450 enzyme [taxane oxetanase 1 (TOT1)] in
Abstract DELLA proteins restrain the cell proliferation and enlargement that characterizes growth of plant organs. Gibberellin stimulates via 26S proteasome–dependent destruction DELLAs, thus relieving DELLA-mediated restraint. Here, we show Arabidopsis thaliana sleepy1gar2-1 (sly1gar2-1) mutant allele encodes a subunit an SCFSLY1 E3 ubiquitin ligase complex. SLY1 (the wild-type form) sly1gar2-1 both confer substrate specificity on this complex specific binding to proteins. However,...
