Common wild rice (Oryza rufipogon), the relative of Asian cultivated sativa), flaunts long, barbed awns, which are necessary for efficient propagation and dissemination seeds. By contrast, O. sativa cultivars have been selected to be awnless or harbor short, barbless facilitate seed processing storage. The transition from awns was a crucial event in domestication. Here, we show that presence is controlled by major gene on chromosome 4, LONG AND BARBED AWN1 (LABA1), encodes...
Abstract Inflorescence architecture is a key agronomical factor determining grain yield, and thus has been major target of cereal crop domestication. Transition from spread panicle typical ancestral wild rice ( Oryza rufipogon Griff.) to the compact present cultivars O. sativa L.) was crucial event in Here we show that controlled by dominant gene, Os LG1, previously reported SBP-domain transcription controls ligule development. Association analysis indicates single-nucleotide polymorphism-6...
Cultivated rice (Oryza sativa) was domesticated from wild rufipogon), which typically displays fewer grains per panicle and longer than cultivated rice. In addition, has long awns, whereas short awns or lacks them altogether. These changes represent critical events in domestication. Here, we identified a major gene, GRAIN NUMBER, LENGTH AND AWN DEVELOPMENT1 (GAD1), that regulates those during GAD1 is located on chromosome 8 predicted to encode small secretary signal peptide belonging the...
During rice domestication and improvement, increasing grain yield to meet human needs was the primary objective. Rice is a quantitative trait determined by multiple genes, but molecular basis for increased still unclear. Here, we show that NUMBER OF GRAINS 1 (NOG1), which encodes an enoyl-CoA hydratase/isomerase, increases of enhancing number per panicle without negative effect on panicles plant or weight. NOG1 can significantly increase commercial high-yield varieties: introduction 25.8% in...
Summary Panicle architecture and seed size are important agronomic traits that directly determine grain yield in rice ( Oryza sativa L.). Although a number of key genes controlling panicle have been cloned characterized recent years, their genetic molecular mechanisms remain unclear. In this study, we identified mutant produced panicles with fascicled primary branching reduced seeds size. We isolated the underlying CLUSTERED PRIMARY BRANCH 1 CPB ) gene, new allele DWARF 11 D11 encoding...
The elimination of seed shattering was a crucial event during crop domestication. Improving and fine-tuning the regulation this process will further enhance grain yield by avoiding losses production. In work, we identified loss-of-shattering mutant suppression shattering1 (ssh1) through screen mutagenized wild rice (Oryza rufipogon) introgression lines with naturally high shattering. Using MutMap approach transformation experiments, isolated genetic factor for shattering, SSH1, which is an...
Grain size is an important yield-related trait in rice. Intensive artificial selection for grain during domestication evidenced by the larger grains of most today's cultivars compared with their wild relatives. However, molecular genetic control rice still not well characterized. Here, we report identification and cloning Size 6 (GS6), which plays role reducing A premature stop at +348 position coding sequence (CDS) GS6 increased width weight significantly. Alignment CDS regions 90 materials...
Summary Inflorescence branching is a key agronomic trait determining rice yield. The primary branch of the ancestral wild ( Oryza rufipogon Griff.) bears few grains, due to minimal secondary branching. By contrast, sativa cultivars have been selected produce large panicles with more branches. Here we showed that CONTROL OF SECONDARY BRANCH 1 COS ) gene, which identical FRIZZY PANICLE FZP ), plays an important role in transition from branches domesticated cultivars. A 4‐bp tandem repeat...
Abstract During the processes of rice domestication and improvement, a trade-off effect between grain number weight was major obstacle for increasing yield. Here, we identify critical gene COG1 , encoding transcription factor OsMADS17, with 65-bp deletion in 5′ untranslated region (5′ UTR) presented cultivated simultaneously through decreasing mRNA translation efficiency. OsMADS17 controls yield by regulating multiple genes that interaction one them, OsAP2-39 has been characterized. Besides,...
Summary Plant architecture is a key agronomical factor determining crop yield and has been major target of cereal domestication. The transition plant from the prostrate tiller typical African wild rice ( Oryza barthii ) to erect cultivated glaberrima was step during domestication rice. Here we show that PROG 7 PROSTRATE GROWTH 7), zinc‐finger transcription gene on chromosome 7, required for growth Mutations in promoter region prog7 reduced level expression base, leading Sequence comparison...
Abstract Oryza nivara , an annual wild AA-genome species of rice, is important gene pool for broadening the genetic diversity cultivated rice ( O. sativa L.). Towards identifying and utilizing favourable alleles from we developed a set introgression lines (ILs) by introducing segments into elite indica variety 93-11 background through advanced backcrossing repeated selfing. Using whole-genome resequencing, high-density map containing 1,070 bin-markers was constructed 131 ILs, with average...
Summary African cultivated rice ( Oryza glaberrima Steud.) was domesticated from its wild progenitor species barthii ) about 3000 years ago. Seed shattering is one of the main constraints on grain production in rice, which causes severe losses during harvest. By contrast, Asian sativa displays greater resistance to seed shattering, allowing higher production. A better understanding regulation would help improve harvesting efficiency rice. Here, we report map‐based cloning and...
The emergence of sterile individuals in the hybrid backcross progeny wild and cultivated rice limits use alleles for improving rice, but molecular mechanisms underlying this sterility remain unclear. Here, we identified semisterile introgression line YIL42, derived from a cross between indica variety Teqing (Oryza sativa) Oryza rufipogon accession YJCWR (Yuanjiang common rice), which exhibits semisterility. Using positional cloning, isolated EMBRYO SAC ABORTION 1 (ESA1), encodes...
To understand the genetic characteristics of traits related to differentiation between cultivated rice and its wild progenitor, factors controlling domestication- yield-related were identified using a BC 3 F 2 population derived from an accession common (donor, Oryza rufipogon Griff.) collected Yuanjiang, Yunnan province, China, indica cultivar, Teqing (recipient, sativa L.). A linkage map consisting 125 simple sequence repeat (SSR) markers was constructed. Based on phenotypes 383 families...
Time to maturity is a critical trait in sorghum (Sorghum bicolor) breeding, as it determines whether variety can be grown particular cropping system or ecosystem. Understanding the nucleotide variation and mechanisms of molecular evolution genes would helpful for breeding programs. In this study, we analyzed diversity Ma3, an important gene sorghum, using 252 cultivated wild materials from all over world. The were based both on race- usage-based groups. We also sequenced 12 around Ma3 185...
ABSTRACT Elevated non‐esterified fatty acids (NEFAs), particularly stearic acid (SA), have a deleterious effect on oocyte maturation, leading to developmental damage and reproductive issues. High SA levels disrupt metabolic processes, inducing lipotoxicity that impairs quality contributes failures through early embryonic losses. This research investigates the lipotoxic effects of assesses protective potential 6‐Gingerol (6‐G) Astaxanthin (AX) porcine oocytes during in vitro maturation (IVM)....
