Elucidation of the genetic control rice architecture is crucial due to global demand for high crop yields. Rice a complex trait affected by plant height, tillering, and panicle morphology. In this study, principal component analysis (PCA) on 8 typical traits related revealed that first (PC), PC1, provided most information determine architecture. A genome-wide association study (GWAS) using PC1 as dependent variable was used isolate gene encoding rice, SPINDLY (OsSPY), activates gibberellin...
Abstract Soil salinization and ground water depletion are increasingly constraining crop production. Identifying useful mechanisms of salt tolerance is an important step towards development salt-tolerant crops. Of particular interest that present in wild relatives, as they may have greater stress than species. The coastal species Vigna marina one the promising plant resources for tolerance. V. luteola another with diverse habitats including seaside riverbank, hereafter, luteola-beach...
Abstract Environment is an important determinant of agricultural productivity; therefore, crops have been bred with traits adapted to their environment. It assumed that the physiology seed germination optimised for various climatic conditions. Here, understand genetic basis underlying germination, we conduct a genome-wide association study considering genotype-by-environment interactions on rate Japanese rice cultivars under different temperature We find 4 bp InDel in one 14-3-3 family...
Elucidation of the genetic control rice seedling vigour is now paramount with global shifts towards direct seeding and consequent demand for early traits in breeding programmes. In a genome-wide association study using an indica-predominant diversity panel, we identified quantitative trait loci (QTLs) root length number seedlings. Among QTLs, one QTL lateral on chromosome 11, qTIPS-11, was associated 32.4% increase number. The locus validated independent backgrounds, predicted glycosyl...
Breeding high-yield crop cultivars has improved agronomic performance for key grain crops (Hirano et al., 2017). However traditional breeding takes years. Molecular genetic studies have identified beneficial trait-associated alleles in elite providing a platform gene-editing techniques such as the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system (Rothan 2019). Most current 'super rice' varieties with high yields several traits. For example...
ABSTRACT Vigna marina (Barm.) Merr. is adapted to tropical marine beaches and has an outstanding tolerance salt stress. Given there are growing demands for cultivating crops in saline soil or with water, it important understand how halophytic species the environments. Here we revealed by positron‐emitting tracer imaging system (PETIS) that V. actively excretes sodium from root during light period but not dark period. The following whole genome sequencing accompanied forward genetic study...
Abstract Genome-wide association studies (GWASs) are used to detect quantitative trait loci (QTL) using genomic and phenotypic data as inputs. While obtained with high throughput low cost, obtaining requires a large amount of effort time. In past breeding programs, researchers breeders have conducted number surveys accumulated results legacy data. this study, we GWAS temperate japonica rice (Oryza sativa) varieties from public database. The the detected several known agriculturally important...
SUMMARY The morphology of rice ( Oryza sativa L.) panicles is an important determinant grain yield, and elucidation the genetic control panicle structure very for fulfilling demand high yield in breeding programs. In a quantitative trait locus (QTL) study using 82 backcross inbred lines (BILs) derived from Koshihikari Habataki, 68 QTLs 25 morphological traits were identified. Gene expression profiling inflorescence meristems BILs was obtained. A combination phenotypic QTL (pQTL) (eQTL)...

Summary Salt tolerance is important to tackle problems of soil salinization and ground water depletion. However, developing salt tolerant crops facing difficulties due limited potential in model plants crop species. Thus, it elucidate how coastal species, such as Vigna marina , adapt saline environments. By comparative transcriptome histological analyses, this study elucidated one aspect achieves exclusion extraordinary tolerance. Under stress, genes involved casparian strip formation were...
Agricultural usage of phosphorus (P) is largely driven by the amount P removed from fields in harvested plant matter as offtake needs to be balanced fertilizer application. Reducing concentration grains a way decrease and reduce requirements or soil mining where insufficient applied. Our objective was assesses genotypic variation for grain present within rice gene pool resolve what extent it affected environment (P supply) associated with genetic factors. About 2-fold concentrations were...
Abstract Some wild species in vigna genus are halophyte that have high potential salt tolerance. V. marina and one accession of luteola been previously identified as tolerant. However, the mechanisms remain elusive studies on phenotypic responses to can be a starting point for understanding tolerant mechanisms. Additional accumulation leaf chlorophyll fluorescence, this study evaluated root system architecture, including total length, surface area tip number, response salt. Results...
Hybrid rice proved to be high‐yielding and is of great importance food safety worldwide. By using gene editing techniques, we generated one‐line hybrid by preventing meiosis from occurring, which can largely contribute maintaining the dominance.
