Haplotype-resolved gapless genome and chromosome segment substitution lines facilitate gene identification in wild rice
The abundant genetic variation harbored by wild rice ( Oryza rufipogon ) has provided a reservoir of useful genes for rice breeding. However, the...

The COG1-OsSERL2 complex senses cold to trigger signaling network for chilling tolerance in japonica rice
Improvement of chilling tolerance is a key strategy to face potential menace from abnormal temperature in rice production, which depends on the...

Identification of a novel QTL and candidate gene associated with grain size using chromosome segment substitution lines in rice
Rice is one of the staple crops in the world. Grain size is an important determinant of rice grain yield, but the genetic basis of the grain size...

Dysfunction of duplicated pair rice histone acetyltransferases causes segregation distortion and an interspecific reproductive barrier
Postzygotic reproductive isolation, which results in the irreversible divergence of species, is commonly accompanied by hybrid sterility,...

Localization of quantitative trait loci for cucumber fruit shape by a population of chromosome segment substitution lines
Cucumber fruit shape, a significant agronomic trait, is controlled by quantitative trait loci (QTLs). Feasibility of chromosome segment substitution...

Detecting CSSLs and yield QTLs with additive, epistatic and QTL×environment interaction effects from Oryza sativa × O. nivara IRGC81832 cross
Chromosome segment substitution lines (CSSLs) are useful tools for precise map** of quantitative trait loci (QTLs) and the evaluation of gene...

Heterotic loci identified for maize kernel traits in two chromosome segment substitution line test populations
Heterosis has been widely used to increase grain quality and yield, but its genetic mechanism remains unclear. In this study, the genetic basis of...

MYB61 is regulated by GRF4 and promotes nitrogen utilization and biomass production in rice
Nitrogen (N) is a macronutrient that boosts carbon (C) metabolism and plant growth leading to biomass accumulation. The molecular connection between...

Dissecting Heterosis During the Ear Inflorescence Development Stage in Maize via a Metabolomics-based Analysis
Heterosis can increase the yield of many crops and has been extensively applied in agriculture. In maize, female inflorescence architecture directly...

Maintaining higher leaf photosynthesis after heading stage could promote biomass accumulation in rice
Leaf photosynthetic rate changes across the growing season as crop plants age. Most studies of leaf photosynthesis focus on a specific growth stage,...

Direct identification of a mutation in OsSh1 causing non-shattering in a rice (Oryza sativa L.) mutant cultivar using whole-genome resequencing
Loss of seed shattering has been regarded as a key step during crop domestication. Mutagenesis contributes to the development of novel crop cultivars...

A transposon insertion in the promoter of OsUBC12 enhances cold tolerance during japonica rice germination
Low-temperature germination (LTG) is an important agronomic trait for rice ( Oryza sativa ). Japonica rice generally has greater capacity for...

qSE7 is a major quantitative trait locus (QTL) influencing stigma exsertion rate in rice (Oryza sativa L.)
Stigma exsertion is a key determinant to increase the efficiency of commercial hybrid rice seed production. The major quantitative trait locus (QTL) qSE7...

Natural variation in OsMYB8 confers diurnal floret opening time divergence between indica and japonica subspecies
The inter-subspecific indica - japonica hybrid rice confer potential higher yield than the widely used indica - indica intra-subspecific hybrid rice....

Characterization of a major QTL for manganese accumulation in rice grain
Some diets lack sufficient manganese (Mn), an essential mineral. Increasing Mn in grain by biofortification could prevent Mn deficiency, but may...
-
Natural variation of OsGluA2 is involved in grain protein content regulation in rice
Grain protein content (GPC) affects rice nutrition quality. Here, we identify two stable quantitative trait loci (QTLs), qGPC-1 and qGPC-10 ,...
-
A heading date QTL, qHD7.2, from wild rice (Oryza rufipogon) delays flowering and shortens panicle length under long-day conditions
Heading date (HD) and panicle length (PL) are important traits that affect rice breeding and are controlled by pleiotropic genes. Some alleles...
