MYB-type transcription factors (TFs) play essential roles in plant growth, development and respond to environmental stresses. Role of MYB-related TFs rice drought stress tolerance is not well documented. Here, we report the isolation characterization a novel TF, OsMYB48-1, rice. Expression OsMYB48-1 was strongly induced by polyethylene glycol (PEG), abscisic acid (ABA), H2O2, dehydration, while being slightly high salinity cold treatment. The protein localized nucleus with transactivation...
Drought is one of the major abiotic stresses that directly implicate plant growth and crop productivity. Although many genes in response to drought stress have been identified, genetic improvement resistance especially food crops showing relatively slow progress worldwide. Here, we reported isolation abscisic acid, ripening (ASR) from upland rice variety, IRAT109 (Oryza sativa L. ssp. japonica), demonstrated overexpression OsASR5 enhanced osmotic tolerance Escherichia coli Arabidopsis by...
Abstract Upland rice is a distinct ecotype that grows in aerobic environments and tolerates drought stress. However, the genetic basis of its resistance unclear. Here, using an integrative approach combining genome-wide association study with analyses introgression lines transcriptomic profiles, we identify gene, DROUGHT1 ( DROT1 ), encoding COBRA-like protein confers rice. specifically expressed vascular bundles directly repressed by ERF3 activated ERF71, both drought-responsive...
Grain size, one of the important components determining grain yield in rice, is controlled by multiple quantitative trait loci (QTLs). Intensive artificial selection for size during domestication evidenced modern cultivars compared to their wild relatives. Here, we report molecular cloning and characterization OsLG3b, a QTL length tropical japonica rice that encodes MADS-box transcription factor 1 (OsMADS1). Six SNPs OsLG3b region led alternative splicing, which were associated with an...
Improving the performance of rice (Oryza sativa) under drought stress has potential to significantly affect productivity. Here, we report that ERF family transcription factor OsLG3 positively regulates tolerance in rice. In our previous work, found a positive effect on grain length without affecting quality. this study, was more strongly expressed upland than lowland conditions. By performing candidate gene association analysis, natural variation promoter is associated with osmotic...
Most agronomic traits in rice are complex and polygenic. The identification of quantitative trait loci (QTL) for grain length is an important objective genetic research breeding programs. Herein, we identified 99 QTL by GWAS based on approximately 10 million single nucleotide polymorphisms from 504 cultivated accessions (Oryza sativa L.), 13 which were validated four linkage populations 92 new length. We scanned the Ho (observed heterozygosity per locus) index coupled-parents crosses mapping...
Low temperature affects the rice plants at all stages of growth. It can cause severe seedling injury and male sterility resulting in yield losses. Using a mini core collection 174 Chinese accessions 273 SSR markers we investigated cold tolerance germination booting stages, as well underlying genetic bases, by association mapping. Two distinct populations, corresponding to subspecies indica japonica showed evident differences its basis. Both were sensitive stress both growth stages. However,...
A robust (long and thick) root system is characteristic of upland japonica rice adapted to drought conditions. Using deep sequencing large scale phenotyping data 795 accessions an integrated strategy combining results from high resolution mapping by GWAS linkage mapping, comprehensive analyses genomic, transcriptomic haplotype data, we identified numbers QTLs affecting length thickness (RL RT) shortlisted relatively few candidate genes for many the small-effect QTLs. Forty four 97 QTL RL RT...
Significance The ability of plants to initiate systemic responses local biotic and abiotic stress is well known. One such example takes place after exposure high-light episodes involves an initial, accumulation reactive oxygen species (ROS) in the region exposed excessive light. Overexcitation photosynthetic apparatus has long been known lead ROS production, but whether this necessary sufficient not Here, we show that synthesis also requires NADPH oxidases located bundle-sheath strands...
Summary Leaves comprise multiple cell types but our knowledge of the patterns gene expression that underpin their functional specialization is fragmentary. Our understanding and ability to undertake rational redesign these cells therefore limited. We aimed identify genes associated with incompletely understood bundle sheath C 3 plants, which represents a key target engineering traits such as 4 photosynthesis into Oryza sativa (rice). To better understand veins, mesophyll rice, we used laser...
Summary Reactive oxygen species (ROS) and the photoreceptor protein phytochrome B (phyB) play a key role in plant acclimation to stress. However, how phyB that primarily functions nuclei impacts ROS signaling mediated by respiratory burst oxidase homolog (RBOH) proteins reside on plasma membrane, during stress, is unknown. Arabidopsis thaliana Oryza sativa mutants, RNA‐Seq, bioinformatics, biochemistry, molecular biology, whole‐plant imaging were used address this question. Here, we reveal...
In the mountainous, rural regions of eastern China, tuberculosis (TB) remains a formidable challenge; however, long-term molecular epidemiological surveillance in these is limited. This study aimed to investigate and spatial epidemiology TB two counties Zhejiang Province, from 2015 2021, elucidate recent transmission drug-resistance profiles. The predominant Lineage 2 (L2) Beijing family accounted for 80.1% total 532 sequenced Mycobacterium (Mtb) strains, showing consistent prevalence over...
Receptor-like kinases (RLKs) are crucial for plant stress responses. Cysteine-rich receptor-like (CRKs), a significant RLK subfamily, typically possess signal peptide, one to four extracellular DUF26 domains, transmembrane domain, and an intracellular serine/threonine kinase domain (Chen, 2001). CRKs land plant-specific, being present in vascular plants but absent bryophytes algae. They have expanded evolutionarily through tandem duplications (Vaattovaara et al., 2019). In Arabidopsis,...
Abstract Plants are essential for life on Earth converting light into chemical energy in the form of sugars. To adjust changes intensity and quality, to become as efficient possible harnessing light, plants utilize multiple receptors, signaling, acclimation mechanisms. In addition altering plant metabolism, development growth, cues sensed by some photoreceptors, such phytochromes, impact many responses biotic abiotic stresses. Central different stresses reactive oxygen species (ROS) that...
Abstract When exposed to high light plants produce reactive oxygen species (ROS). In Arabidopsis thaliana local accumulation of ROS preferentially takes place in bundle sheath strands, but little is known about how this response place. Using rice and the probes diaminobenzidine 2’,7’-dichlorodihydrofluorescein diacetate, we found that after exposure light, were produced more rapidly strands than mesophyll cells. This was not affected either by CO 2 supply or photorespiration. Consistent with...
Abstract Background Improving performance of rice under drought stress has potential to significant impact on productivity. Previously we reported that OsLG3 positively control grain length and yield. Results In this study, found was more strongly expressed in upland compared lowland condition. Candidate gene association analysis showed the natural variation associated with tolerance water deficit germinating seeds. Transgenic enhanced expression exhibited improved is most likely due ROS...
