Drought and salinity are major abiotic stresses to crop production. Here, we show that overexpression of stress responsive gene SNAC1 (STRESS-RESPONSIVE NAC 1) significantly enhances drought resistance in transgenic rice (22-34% higher seed setting than control) the field under severe conditions at reproductive stage while showing no phenotypic changes or yield penalty. The also shows improved salt tolerance vegetative stage. Compared with WT, more sensitive abscisic acid lose water slowly...
Grain yield in many cereal crops is largely determined by grain size. Here we report the genetic and molecular characterization of GS3 , a major quantitative trait locus for It functions as negative regulator size organ The wild-type isoform composed four putative domains: plant-specific regulation (OSR) domain N terminus, transmembrane domain, tumor necrosis factor receptor/nerve growth receptor (TNFR/NGFR) family cysteine-rich von Willebrand type C (VWFC) terminus. These domains function...
Hybrid rice has greatly contributed to the global increase of productivity. A major component that facilitated development hybrids was a mutant showing photoperiod-sensitive male sterility (PSMS) with its fertility regulated by day length. Transcriptome studies have shown large portions eukaryotic genomic sequences are transcribed long noncoding RNAs (lncRNAs). However, potential roles for only few lncRNAs been brought light at present. Thus, great efforts be invested understand biological...
Abstract New evidence suggests a role for the plant growth hormone auxin in pathogenesis and disease resistance. Bacterial infection induces accumulation of indole-3-acetic acid (IAA), major type auxin, rice (Oryza sativa). IAA expression expansins, proteins that loosen cell wall. Loosening wall is key but may also make vulnerable to biotic intruders. Here, we report GH3-8, an auxin-responsive gene functioning auxin-dependent development, activates resistance salicylic signaling– jasmonic...
Rice bacterial blight, caused by Xanthomonas oryzae pv. (Xoo), is one of the most serious rice diseases worldwide. A gene, Xa26, conferring resistance against Xoo at both seedling and adult stages was isolated map-based cloning strategies from cultivar Minghui 63. Xa26 belongs to a multigene family consisting four members. It encodes leucine-rich repeat (LRR) receptor kinase-like protein constitutively expressed. Sequence analysis revealed that IRBB3 Zhachanglong lines are resistant broad...
Disease resistance and sexual reproductive development are generally considered as separate biological processes, regulated by different sets of genes. Here we show that xa13 , a recessive allele conferring disease against bacterial blight, one the most devastating rice diseases worldwide, plays key role in both pollen development. The dominant allele, Xa13 is required for growth Promoter mutations cause down-regulation expression during host–pathogen interaction, resulting fully confers...
Although 109 WRKY genes have been identified in the rice genome, functions of most are unknown. Here, we show that OsWRKY13 plays a pivotal role disease resistance. Overexpression can enhance resistance to bacterial blight and fungal blast, two devastating diseases worldwide, at both seedling adult stages, shows no influence on fertility. This overexpression was accompanied by activation salicylic acid (SA) synthesis-related SA-responsive suppression jasmonic (JA) JA-responsive genes. bound...
Adverse environmental conditions such as high temperature and drought stress greatly limit the growth production of crops worldwide. Several NAC (NAM, ATAF1/2, CUC2) proteins have been documented important regulators in responses, but molecular mechanisms are largely unknown. Here, a stress-responsive gene, SNAC3 (ONAC003, LOC_Os01g09550), conferring heat tolerance rice is reported. was ubiquitously expressed its transcript level induced by drought, temperature, salinity stress, abscisic...
Abstract Mitogen-activated protein kinase (MAPK) cascades have been identified in various signaling pathways involved plant development and stress responses. We a drought-hypersensitive mutant (drought-hypersensitive mutant1 [dsm1]) of putative MAPK (MAPKKK) gene rice (Oryza sativa). Two allelic dsm1 mutants were more sensitive than wild-type plants to drought at both seedling panicle stages. The lost water rapidly under stress, which was agreement with the increased drought-sensitivity...
Abstract OsbZIP46 is one member of the third subfamily bZIP transcription factors in rice (Oryza sativa). It has high sequence similarity to ABA-responsive element binding factor (ABF/AREB) ABI5 and OsbZIP23, two transcriptional activators positively regulating stress tolerance Arabidopsis (Arabidopsis thaliana) rice, respectively. Expression was strongly induced by drought, heat, hydrogen peroxide, abscisic acid (ABA) treatment; however, it not salt cold stresses. Overexpression native gene...
Plant responses to abiotic stresses are coordinated by arrays of growth and developmental processes. Indole-3-acetic acid (IAA) abscisic (ABA) play critical roles in programmes environmental responses, respectively, through complex signalling metabolism networks. However, crosstalk between the two phytohormones stress remains largely unknown. Here, it is reported that a GH3 family gene, OsGH3-2, encoding an enzyme catalysing IAA conjugation amino acids, involved modulation ABA level...
Manipulating grain size is an effective strategy for increasing cereal yields. Here we identify a pathway composed of five subunits the heterotrimeric G proteins that regulate length in rice. The Gβ protein essential plant survival and growth. Gα provides foundation expansion. Three Gγ proteins, DEP1, GGC2 GS3, antagonistically size. DEP1 GGC2, individually or combination, increase when complex with Gβ. having no effect on by itself, reduces competitively interacting By combining different...
Abstract Drought is a major limiting factor for crop production. To identify critical genes drought resistance in rice (Oryza sativa), we screened T-DNA mutants and identified drought-hypersensitive mutant, dsm2. The mutant phenotype was caused by insertion gene encoding putative β-carotene hydroxylase (BCH). BCH predicted the biosynthesis of zeaxanthin, carotenoid precursor abscisic acid (ABA). amounts zeaxanthin ABA were significantly reduced two allelic dsm2 after stress compared with...
Hybrid sterility is a major form of postzygotic reproductive isolation. Although isolation has been key issue in evolutionary biology for many decades wide range organisms, only very recently few genes were identified. The Asian cultivated rice (Oryza sativa L.) divided into two subspecies, indica and japonica. Hybrids between japonica varieties are usually highly sterile. A special group germplasm, referred to as wide-compatibility varieties, able produce fertile hybrids when crossed both...
Abstract Although allelic diversity of genes has been reported to play important roles in different physiological processes, information on defense-responsive host-pathogen interactions is limited. Here, we report that a pair genes, OsWRKY45-1 and OsWRKY45-2, which encode proteins with 10-amino acid difference, opposite rice (Oryza sativa) resistance against bacterial pathogens. Bacterial blight caused by Xanthomonas oryzae pv (Xoo), streak oryzicola (Xoc), fungal blast Magnaporthe grisea...
Abstract Grains from cereals contribute an important source of protein to human food, and grain content (GPC) is determinant nutritional quality in cereals. Here we show that the quantitative trait locus (QTL) qPC1 rice controls GPC by regulating synthesis accumulation glutelins, prolamins, globulins, albumins starch. encodes a putative amino acid transporter OsAAP6 , which functions as positive regulator rice, such higher expression correlated with GPC. greatly enhances root absorption...
Abstract Breeding crops with the quality of broad-spectrum disease resistance using genetic resources is one principal goals crop improvement. However, molecular mechanism remains largely unknown. Here, we show that GH3-2, encoding an indole-3-acetic acid (IAA)-amido synthetase, mediates a to bacterial Xanthomonas oryzae pv and oryzicola fungal Magnaporthe grisea in rice (Oryza sativa). IAA, major form auxin rice, results more vulnerable invasion different types pathogens, which at least...
Conquering Rice Sterility The hybrid sterility occurring among rice species has long been a puzzle and hampers progress in breeding crops with improved performance yield characteristics. Yang et al. (p. 1336 ) have identified three linked genes encoding killer, partner, protector protein. killer partner work together to kill female gametes not carrying the functional protector, resulting preferential transmission of which also causes segregation distortion progeny. This explanation for how...
Huge efforts have been invested in the last two decades to dissect genetic bases of complex traits including yields many crop plants, through quantitative trait locus (QTL) analyses. However, almost all studies were based on linkage maps constructed using low-throughput molecular markers, e.g. restriction fragment length polymorphisms (RFLPs) and simple sequence repeats (SSRs), thus are mostly low density not able provide precise complete information about numbers locations genes or QTLs...
Significance New discoveries have been continuously made in recent years on the roles of noncoding RNAs regulating biological processes. Phased small-interfering (phasiRNAs) may be newest member discovered years. The photoperiod-sensitive male sterility (PSMS) rice is a very valuable germplasm that started era two-line hybrid rice. Here we show phasiRNAs generated by long-noncoding RNA PMS1T encoded Pms1 locus regulates PSMS This work provides case associating with trait, especially an...
