Rice blast is one of the most destructive diseases affecting rice production worldwide. The development and rational use resistant varieties has been effective economical measure to control blast. In this review, we summarized cloning utilization resistance genes, such as Pi1, Pi2, Pi9, Pi54, Pigm Piz-t. We concluded that three main problems in current breeding are: availability few R (resistance) genes confer both seedling panicle blast, effect pyramided lines not result a simple...
Summary Phytochrome‐interacting factors ( PIF s) play major roles in regulating plant growth and development, but their drought stress remain elusive. Here, we cloned characterized a maize Zea mays ) transcription factor, Zm 1 . The expression level of was significantly induced by independent abscisic acid ABA treatments. transgenic rice Arabidopsis displayed water saving resistance, which were associated with reduced stomatal aperture transpiration rate. Moreover, the hypersensitive to...
Abstract Background Balancing the yield, quality and resistance to disease is a daunting challenge in crop breeding due negative relationship among these traits. Large-scale genomic landscape analysis of germplasm resources considered be an efficient approach dissect genetic basis complex Central China one main regions where japonica rice produced. However, dozens high-yield varieties this region still exist with low or susceptibility blast disease, severely limiting their application...
The role of de novo evolved genes from non-coding sequences in regulating morphological differentiation between species/subspecies remains largely unknown. Here, we show that a rice gene GSE9 contributes to grain shape difference indica/xian and japonica/geng varieties. evolves previous region wild Oryza rufipogon through the acquisition start codon. This is inherited by most japonica varieties, while original sequence (absence codon, gse9) present majority indica Knockout varieties leads...
Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is a major constraint to rice production worldwide. In this study, we developed monogenic near-isogenic lines (NILs) NIL Pi9, Pizt , and Pi54 carrying genes Pizt, Pi54, respectively, marker assisted backcross breeding using 07GY31 as japonica genetic background with good agronomic traits. Polygene pyramid (PPLs) PPL Pi9+Pi54 combining Pi9 Pizt+Pi54 were then corresponding NILs recovery rates of more than 97%. Compared 07GY31,...
Cold stress is a major factor limiting rice (Oryza sativa) production worldwide, especially at the seedling and booting stages. The identification of genes associated with cold tolerance (CT) in important for sustainable food production. Here, we report results genome-wide association study to identify genetic loci CT by using 1,033-accession diversity panel. We identified five CT-related stage. Accessions carrying multiple cold-tolerant alleles displayed higher seed-setting rate than did...
Rice blast caused by Magnaporthe oryzae is the most devastating disease of rice and poses a serious threat to world food security. In this study, distribution effectiveness 18 R genes in 277 accessions were investigated based on pathogenicity assays molecular markers. The results showed that exhibited some degree resistance (resistance frequency, RF >50%). Accordingly, observed harbor two or more genes, number harbored was significantly positively correlated with RF. Some demonstrated be...
Broad-spectrum resistance gene pyramiding helps the development of varieties with broad-spectrum and durable to M. oryzae. However, detailed information about how these different sources genes act together or what are best combinations achieve is limited. Here a set fifteen polygene lines (PPLs) were constructed using marker-assisted selection (MAS). Using artificial inoculation assays at seedling heading stage, combined natural induction identification under multiple field environments, we...
Rice blast and bacterial blight are important diseases of rice (Oryza sativa) caused by the fungus Magnaporthe oryzae bacterium Xanthomonas pv. (Xoo), respectively. Breeding varieties for broad-spectrum resistance is considered most effective sustainable approach to controlling both diseases. Although dominant genes have been extensively used in breeding production, generating disease-resistant altering susceptibility (S) that facilitate pathogen compatibility remains unexplored. Here, using...
Abstract Stomata are crucial valves coordinating the fixation of carbon dioxide by photosynthesis and water loss through leaf transpiration. Phytochrome interacting factors (PIFs) negative regulators red light responses that belong to basic helix–loop–helix family transcription factors. Here, we show rice (Oryza sativa) PIF gene OsPIL15 acts as a regulator stomatal aperture control transpiration in rice. reduces activating ABSCISIC ACID INSENSITIVE 5 (OsABI5), which encodes critical positive...
Rice (Oryza sativa L.) bacterial leaf streak (BLS) caused by Xanthomonas oryzae pv. oryzicola (Xoc) seriously threatens rice production. This disease can be controlled cultivating lines with appropriate resistance genes. To discover new loci, a natural population of 246 sequenced backbone varieties indica was inoculated Xoc in the field, and their level evaluated. The structure, distribution phenotypes, effect combinations genes were analyzed genome-wide association study. On basis single...
Knocking out three susceptibility genes (Pi21, Bsr-d1, and Xa5) in a rice breeding line that contains the resistance Piz-t produced enhanced broad-spectrum against fungal pathogen Magnaporthe oryzae bacterial Xanthomonas pv. without obvious growth penalty.
Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is one of most important diseases rice. Utilization blast-resistance genes economical, effective, and environmentally friendly way to control disease. However, genetic resources with broad-spectrum resistance (BSR) that effective throughout rice growth period are rare. In this work, using a genome-wide association study, we identify new gene, Pijx, which encodes typical CC-NBS-LRR protein. Pijx derived from wild species confers...
Abstract Plants are unique with tremendous chemical diversity and metabolic complexity, which is highlighted by estimates that green plants collectively produce metabolites numbering in the millions. Plant play crucial roles all aspects of plant biology, like growth, development, stress responses, etc. However, lack a reference metabolome for plants, paucity high-quality standard compound spectral libraries related analytical tools, have hindered discovery functional study phytochemicals...
Cold stress causes various injuries to rice seedlings in low-temperature and high-altitude areas is therefore an important factor affecting production such areas. In this study, root conductivity (RC) was used as indicator map quantitative trait loci (QTLs) of cold tolerance Oryza rufipogon Griff., Dongxiang wild (DX), at its two-leaf stage. The correlation coefficients between RC the plant survival rate (PSR) seedling maturity stages were –0.85 –0.9 (P = 0.01), respectively, indicating that...
Plant polygalacturonase-inhibiting protein (PGIP) is a structural that can specifically recognize and bind to fungal polygalacturonase (PG). PGIP plays an important role in plant antifungal activity. In this study, maize gene, namely ZmPGIP3, was cloned characterized. Agarose diffusion assay suggested ZmPGIP3 could inhibit the activity of PG. expression significantly induced by wounding, Rhizoctonia solani infection, jasmonate, salicylic acid. might be related disease resistance. The gene...
