Abstract The external application of nitrogen (N) fertilizers is an important practice for increasing crop production. However, the excessive use significantly increases production costs and causes environmental problems, making improvement N-use efficiency (NUE) crucial sustainable agriculture in future. Here we show that rice (Oryza sativa) NUE quantitative trait locus DULL NITROGEN RESPONSE1 (qDNR1), which involved auxin homeostasis, reflects differences nitrate (NO3−) uptake, N...
Rice (Oryza sativa L.) is a major dietary source of cadmium (Cd). Developing rice varieties with reduced Cd levels in the grain cost-effective and practical approach to enhance food safety, particularly regions high contamination. However, genetic mechanisms underlying accumulation grains are not fully understood. In this study, we identified eight quantitative trait loci (QTLs) associated through substitution mapping using single segment lines (SSSLs). These QTLs, named qCd‐2‐1, qCd‐3‐1,...
Summary Improving cold tolerance at the flowering stage (CTF) in rice is crucial for minimising yield loss, making identification and application of cold‐tolerant genes QTLs imperative effective molecular breeding. The long lead time, dependence on treatment conditions, inherent complexity trait make studying genetic basis CTF challenging. To date, fine‐mapping or cloning specific to has not yet been achieved. In this study, single segment substitution lines (SSSLs) were constructed using...
Abstract Background Grain chalkiness is one of important factors affected rice grain quality. It known that by the high temperature during seed filling period. Although a larger QTLs for were reported across all 12 chromosomes, only few fine mapped or cloned up to now. Here, we map two in single-segment substitution lines (SSSLs), 11–09 with segment from O. sativa and HP67–11 glaberrima. Results The SSSLs was significantly lower than recipient Huajingxian 74 (HJX74) consecutive 8 cropping...
Sleep apnea syndrome (SAS) is a common but underdiagnosed health problem related to impaired quality of life and increased cardiovascular risk. In order solve the complicated expensive operation procedures for clinical diagnosis sleep apnea, here we propose small low-cost wearable diagnostic system. The system uses photoplethysmography (PPG) optical sensor collect human pulse wave signals blood oxygen saturation synchronously. Then multiscale entropy random forest algorithms are used process...
Abstract Rice ( Oryza sativa L.) is an important staple crop. The exploitation of the great heterosis that exists in inter-subspecific crosses between indica and japonica rice has long been considered as a promising way to increase yield potential. However, male female sterility frequently occurred hybrids hampered utilization heterosis. Here we report hybrid mainly affected by genes at Sb , Sc Sd Se loci for F 1 gene S5 locus sterility. -compatible lines (ICJLs) developed pyramiding allele...
Abstract Background Stigma exsertion rate (SER) is a key determinant for the outcrossing ability of male sterility lines (MSLs) in hybrid rice seed production. In process domestication, cultivated varieties decreased, while that wild Oryza species kept strong. Here, we detected quantitative trait loci (QTLs) controlling SER using set single-segment substitution (SSSLs) derived from O. glumaepatula , species. Results Seven QTLs were located on 5 chromosomes. qSER-1a and qSER-1b chromosome 1....
Between the two major rice subspecies, indica varieties generally exhibit higher nitrate (NO3‒) uptake and nitrogen (N)-use efficiency (NUE) than japonica varieties. Introducing efficient NO3‒ utilization alleles from into could improve NUE, at same time uncover unknown regulators of metabolism. Here, we identify OsWRKY23 as a key regulator NUE differences between rice. The OsWRKY23indica allele exhibits reduced transcriptional activation negative auxin accumulation, DULL NITROGEN RESPONSE1...
Heading date is an important agronomic trait of rice, which directly determines adaptability and yield. Selection for natural variated alleles heading genes manifestation rice domestication that allows to spread more broad geographic areas. In this study, three the Hd17 gene were identified by sequence analysis 14 single-segment substitution lines, 6 wild species, 2524 accessions O. sativa. The Hd17-1 allele ancestral type with a middle date. Hd17-2 was caused functional nucleotide...
<title>Abstract</title> Intergeneric hybridization and domestication breeding is an efficient means for utilizing wild rice germplasm resources. In this study, we constructed gap-less genome assemblies two CC, BBCC one CCDD rices to explore the role of C subgenome in diversification. Furthermore, assembled a cultivated (AA) further developed A/C hybrids with enhanced resistance BPH using hybrid embryo rescue system. To facilitate tracking chromosomes backcross selfed progeny these hybrids,...
Heading date directly determines the planting districts and seasons, thus plays an important role for producing introducing of varieties. Limited to materials methodologies, analysis epistasis still presents obvious challenge. This thesis estimated effectively four types epistatic components among dual QTLs on heading based eight single segment substitution lines (SSSLs) in rice. The results confirmed that they carried truly with QTLs. Eleven pairs were 50.0% significant effects, which...
Abstract Background Drought stress is an adverse factor with deleterious effects on several aspects of rice growth. However, the mechanism underlying drought resistance in remains unclear. To understand molecular response rice, drought-sensitive CSSL (Chromosome Single-substitution Segment Line) PY6 was used to map QTLs sensitive phenotypes and reveal impact transcriptional profiling. Results The QTL dss-1 mapped onto short arm chromosome 1 rice. According transcriptomic analysis, identified...
Through substitution mapping strategy, two pairs of closely linked QTLs controlling stigma exsertion rate were dissected from chromosomes 2 and 3 the four fine mapped. Stigma (SER) is an important trait affecting outcrossing ability male sterility lines in hybrid rice. This complex was controlled by multiple affected environment condition. Here, we dissected, respectively, tightly for SER on mapping. On chromosome 2, linkage QTLs, qSER-2a qSER-2b, located region 1288.0 kb, were, delimited to...
Asian cultivated rice is a self-pollinating crop, which has already lost some traits of natural outcrossing in the process domestication. However, male sterility lines (MSLs) need to have strong ability produce hybrid seeds by with restorer parents seed production. Stigma exsertion rate (SER) trait related ability. Reconstruction high-SER essential MSL breeding rice. In previous studies, we detected eighteen quantitative loci (QTLs) for SER from Oryza sativa, glaberrima , and glumaepatula...
