Success of modern agriculture relies heavily on breeding crops with maximal regional adaptability and yield potentials. A major limiting factor for crop cultivation is their flowering time, which strongly regulated by day length (photoperiod) temperature. Here we report identification characterization Days to heading 7 (DTH7), a genetic locus underlying photoperiod sensitivity grain in rice. Map-based cloning reveals that DTH7 encodes pseudo-response regulator protein its expression...
By using a whole-genome oligonucleotide microarray, designed based on known and predicted indica rice genes, we investigated transcriptome profiles in developing leaves panicles of superhybrid LYP9 its parental cultivars 93-11 PA64s. We detected 22,266 expressed genes out 36,926 total set collectively from 7 tissues, including at seedling tillering stages, flag booting, heading, flowering, filling stage. Clustering results showed that the F1 hybrid's expression resembled those lines more...
Abstract Traits such as grain shape, panicle length and seed shattering, play important roles in yield harvest. In this study, the cloning functional analysis of PANICLE TRAITS 2 ( PT2 ), a novel gene from Indica rice Chuandali (CDL), is reported. synonymous with Growth‐Regulating Factor 4 OsGRF4 which encodes growth‐regulating factor that positively regulates shape negatively shattering. Higher expression correlated larger grain, longer lower A unique mutation, occurs at OsmiRNA396 target...
Chilling stress is considered the major abiotic affecting growth, development, and yield of rice. To understand transcriptomic responses methylation regulation rice in response to chilling stress, we analyzed a cold-tolerant variety (Oryza sativa L. cv. P427). The physiological properties, transcriptome, P427 seedlings under low-temperature (2-3 °C) were investigated. We found that exhibited enhanced tolerance low temperature, likely via increasing antioxidant enzyme activity promoting...
Abstract Genes that provide resistance to fungi and/or bacteria usually reduce plant growth and ultimately affect grain yield. Thus, crop breeding programs need find genetic resources balance disease with growth. The receptor kinase FERONIA regulates cell survival in Arabidopsis. Here, we investigate, rice, the role of members FERONIA-like (FLR) gene family between response fungal pathogen Magnaporthe oryzae (Pyricularia oryzae), which causes most devastating rice. We carried out genome-wide...
Grain shape as a major determinant of rice yield and quality is widely believed to be controlled by quantitative trait loci (QTL). We have identified novel gene "GS2" largely regulate grain length width in rice. The GS2 allele the big-grain line 'CDL' functioned dominant manner. In present study, we employed chromosome walking strategy residual heterozygous lines from recombinant inbred population between cultivar "R1126" CDL, located an interval ~ 33.2 kb flanked marker GL2-35-1 GL2-12 long...
Abstract The influence of block forms on the shear behaviour soil–rock mixtures with soft blocks (soft S–RMs) can be efficiently investigated by discrete element method (DEM) basis accurate 3D models accounting for breakage. This paper proposes a novel modelling approach, based spherical harmonics series, generation geometries different but same convexity and angularity. An already existing non-overlapping approach was improved, characterized reduced computational cost, set-up DEM A number...
The Shenyu River, as the tributary of Jinsha River closest to Wudongde Hydropower Station, has had seven landslides developed on its right bank, forming an interconnected landslide group system. evolution and future development trends have a significant impact safe operation Station. Using geological field surveys exploration data, we studied analyzed formation mechanism bank in reservoir area main conclusions are follows: local structure study is mainly composed north–south faults folds,...
Low temperature is one of the major abiotic stresses that severely restrict development rice. It has been demonstrated previously OsGRF4 enhances cold tolerance in rice, molecular mechanism which remains unknown. This study employed a combination proteome and ubiquitylome approaches to analyze mediated chilling between overexpression line (OX) wild type (CK). Proteome results showed 6,157 proteins were identified 5,045 quantified after 24-h treatment. A total 59 upregulated 63 downregulated...
RNA metabolism regulation is crucial for the modulation of gene expression in plants subjected to external stresses. However, how transmit signals via membrane receptors drive has not been determined. In this study, we found that rice FERONIA-like receptor 2 (FLR2) modulates innate immunity by inducing translation immune regulator OsEIL1 promote resistance Magnaporthe oryzae. FLR2 interacts with and phosphorylates mRNA processing factor CONSTITUTIVE EXPRESSER OF PATHOGENESIS-RELATED GENES 5...
To clarify the microRNA (miRNA)-target gene axis is involved in response to pathogen-associated molecular pattern (PAMP)-induced oxidative stress shellfish, full-length cDNA of a novel mitogen-activated protein kinase-interacting kinase 1 ( MNK1 ) homolog from scallop Patinopecten yessoensis PyMNK1 was cloned and characterized. The interaction between miR-1985 verified, then responses possible function miR-1985, , miR-1985/ poly(I:C) (a classic virus-related PAMP) stimulation P. were...
Soil salinization is a threat to food security. China rich in saline land resources for potential and current utilization. The cultivation promotion of salt-tolerant rice varieties can greatly improve the utilization this land. super hybrid Chaoyouqianhao (CY1000) one most widely used, but molecular mechanism underlying its salt tolerance not clear.In study, characteristics CY1000 parents were evaluated field laboratory. results showed that aboveground parts barely influenced by stress,...
