Pollen grains of Arabidopsis (Arabidopsis thaliana) contain two haploid sperm cells enclosed in a vegetative cell. Upon germination, the cell extrudes pollen tube that carries to an ovule for fertilization. Knowing identity, relative abundance, and splicing patterns transcripts will improve our understanding allow investigation tissue-specific plants. Most transcriptome studies have used ATH1 microarray, which does not assay splice variants lacks specific probe sets many genes. To...
Thiosulfate oxidation by microbes has a major impact on global sulfur cycling. Here, we provide evidence that bacteria within various Roseobacter lineages are important for thiosulfate in marine biofilms. We isolate and sequence the genomes of 54 biofilm-associated strains, finding conserved sox gene clusters plasmids, pointing to niche-specific lifestyle. Analysis ocean metagenomic data suggests strains abundant biofilms mats substrates, including stones, artificial surfaces, plant roots,...
Grain weight and grain number are two important traits directly determining yield in rice. To date, a lot of genes related to have been identified; however, the regulatory mechanism underlying these remains largely unknown. In this study, we studied biological function OsSPL18 during panicle development Knockout (KO) mutants exhibited reduced width thickness, length number, but increased tiller number. Cytological analysis showed that regulates spikelet hulls by affecting cell proliferation....
Summary Nitrogen (N) is one of the key essential macronutrients that affects rice growth and yield. Inorganic N fertilizers are excessively used to boost yield generate serious collateral environmental pollution. Therefore, improving crop use efficiency (NUE) highly desirable has been a major endeavour in improvement. However, only few regulators have identified can be improve NUE date. Here we show NIN‐like protein 4 (OsNLP4) significantly improves Field trials consistently showed loss‐of‐...
A leaf-to-caryopsis abscisic acid transport mechanism ensures normal seed development in response to variable temperatures.
Xiangling628S (XL628S), Longke638S (LK638S), and Jing4155S (J4155S) are excellent two-line sterile lines, Huazhan (HZ) Wu-Shan-Si-Miao (WSSM) both three-line restorers. LK638S J4155S derived from XL628S, belonging to the same pedigree, while WSSM is HZ, another pedigree. Between 2018 2020, planting area of JLYHZ, JLY534, LLYHZ ranked among top 3 China's hybrid rice (Figure 1a). In published genomes, 82 129 gaps remained for assemblies, respectively, no assemblies XL628S were observed (Qin et...
Tetraspanins are evolutionary conserved transmembrane proteins present in all multicellular organisms. In animals, they known to act as central organizers of membrane complexes and thought facilitate diverse biological processes, such cell proliferation, movement, adhesion, fusion. The genome Arabidopsis (Arabidopsis thaliana) encodes 17 members the tetraspanin family; however, little is about their functions plant development. Here, we analyzed phylogeny, protein topology, domain structure...
Both grain size and number are significant for rice yield. In the past decade, a of genes related to have been documented, however, regulatory mechanisms underlying them remains ambiguous. We identified small (sg2) mutant in an EMS library generated from indica variety, Shuhui498. Using MutMap gene mapping strategy, we two linkage regions on chromosome 7 8, respectively, consistent with segregation ratios F2 population. focused region named this locus as 08sg2. One three SNPs was located...
The successful application of heterosis in hybrid rice has dramatically improved productivity, but the genetic mechanism for remains unclear. In this study, we generated two populations F 1 hybrids with present-day commercial parents, genotyped parents 50k SNP chip and genome resequencing, recorded phenotype ∼2,000 at three field trials. By integrating these data collected genotypes ∼4,200 landraces varieties that were reported previously, found male female have different levels...
Significant achievements have been made in breeding programs for the heavy-panicle-type (HPT) rice (Oryza sativa) Southwest China. The HPT varieties now exhibit excellent lodging resistance, allowing them to overcome greater pressures caused by heavy panicles. However, genetic mechanism of this resistance remains elusive. Here, we isolated a major quantitative trait locus, Panicle Neck Diameter 1 (PND1), and identified causal gene as GRAIN NUMBER 1A/CYTOKININ OXIDASE 2 (Gn1A/OsCKX2). null...
Abstract Grain size is an important trait that directly affects grain yield in rice; however, the genetic and molecular mechanisms regulating remain unclear. In this study, we identified a mutant, length weight 10 (glw10), which exhibited significantly reduced weight. Histological analysis demonstrated GLW10 cell expansion, regulates size. MutMap-based gene mapping transgenic experiments encodes putative brassinosteroid (BR) signalling kinase, OsBSK2. OsBSK2 plasma membrane protein,...
Abstract Improving quality is an essential goal of rice breeding and production. However, not solely determined by genotype, but also influenced the environment. Phenotype plasticity refers to ability a given genotype produce different phenotypes under environmental conditions, which can be representation stability traits. Seven traits 141 hybrid combinations, deriving from test-crossing 7 thermosensitive genic male sterile (TGMS) 25 restorer lines, were evaluated at 5 trial sites with...
Summary Gibberellic acid (GA) plays a central role in many plant developmental processes and is crucial for crop improvement. DELLA proteins, the core suppressors GA signaling pathway, are degraded by via 26S proteasomal pathway to release response. However, little known about phosphorylation‐mediated regulation of proteins. In this study, we combined response assays with protein–protein interaction analysis infer connection between Arabidopsis thaliana DELLAs C‐TERMINAL DOMAIN...
The Ideal Plant Architecture 1 (IPA1) transcription factor promotes rice yield and immunity through phosphorylation at its amino acid residue Ser163 as a switch. Although phosphorylated IPA1 mimic, IPA1(S163D), directly targets the promoter of immune response gene WRKY45, it cannot activate expression. Here, we identified co-activator RING-finger E3 ligase interactor 7 (IPI7), which fine-tunes transcriptional activity to timely promote plant simultaneously maintain growth for yield. IPI7...
The pollen grain contains the male gametophyte that extends a tube grows through female tissues in order to deliver sperm embryo sac for double fertilization. Growing tubes form periodic callose plugs are thought block off older parts of and maintain cytoplasm near growing tip. morphology patterns their deposition were previously shown vary among species, but variation within species had not been examined. We therefore systematically examined plug Arabidopsis thaliana ecotypes, tested...
Quinoa, a cool-weather high-altitude crop, is susceptible to low-temperature stress throughout its reproductive phase. Herein, we performed broadly targeted metabolic profiling of quinoa seedlings explore the metabolites’ dynamics in response and transcriptome analysis determine underlying genetic mechanisms. Two variants, namely, Dian Quinoa 2324 281, were exposed temperatures −2, 5, 22 °C. A total 794 metabolites detected; 52,845 genes, including 6628 novel annotated using UPLC-MS/MS...
Heterosis is a phenomenon that hybrids show superior performance over their parents. The successful utilization of heterosis has greatly improved rice productivity, but the molecular basis remains largely unclear.Here, transcriptomes young panicles and leaves two widely grown two-line super hybrid varieties (Jing-Liang-You-Hua-Zhan (JLYHZ) Long-Liang-You-Hua-Zhan (LLYHZ)) parents were analyzed by RNA-seq. Transcriptome profiling revealed 1,778 ~ 9,404 differentially expressed genes (DEGs) in...
