Abstract Background Heterosis is a phenomenon in which hybrids exhibit superior performance relative to parental phenotypes. In addition the heterosis of above-ground agronomic traits on most existing studies have focused, root also an indispensable component entire plant and major importance breeding. Consequently, systematic investigations heterosis, particularly reproductive-stage rice, are needed. The recent advent RNA sequencing technology (RNA-Seq) provides opportunity conduct in-depth...
Premature leaf senescence in rice is one of the most common factors affecting plant's development and yield. Although methyltransferases are involved diverse biological functions, their roles have not been previously reported. In this study, we identified premature 3 (pls3) mutant rice, which led to early heading date. Further investigations revealed that was triggered by accumulation reactive oxygen species. Using physiological analysis, found chlorophyll content reduced pls3 leaves, while...
Circadian clocks coordinate internal physiology and external environmental factors to regulate cereals flowering, which is critical for reproductive growth optimal yield determination. In this study, we aimed confirm the role of OsLUX in flowering time regulation rice. Further research illustrates how OsELF4s–OsELF3-1–OsLUX complex directly regulates flowering-related genes mediate rice heading. We identified a circadian gene by MutMap method. The transcription levels were evaluated WT oslux...
A dynamic plant architecture is the basis of adaptation to changing environments. Although many genes regulating leaf rolling have been identified, directly associated with water homeostasis are largely unknown. Here, we isolated a rice mutant, 1 (dlr1), characterized by 'leaf unfolding in morning-leaf at noon-leaf evening' during sunny day. Water content was decreased rolled leaves and sprayed on caused reopening, indicating that vivo deficiency induced rolling. Map-based cloning expression...
Root system development is an important target for improving yield in rice. Active roots that can take up nutrients more efficiently are essential grain yield. In this study, we performed quantitative trait locus (QTL) analyses using 215 recombinant inbred lines derived from a cross between Xieqingzao B (XB), maintainer line with short and R9308, restorer long roots. Only QTLs associated root length were mapped on chromosomes 7. The QTL, named qRL7, was located markers RM3859 RM214...
Calcium-dependent protein kinases (CPKs), the best-characterized calcium sensors in plants, regulate many aspects of plant growth and development as well adaptation to biotic abiotic stresses. However, how CPKs antioxidant defense system remains largely unknown. We previously found that impaired function OsCPK12 leads oxidative stress rice, with more H
With 2 figures and 4 tables Abstract A recombinant inbred line (RIL) population, consisting of 238 F 12 lines derived from ‘R9308’/’Xieqingzao B’, the parents a super hybrid rice in China, was developed for mapping quantitative trait locus (QTL) nitrogen deficiency tolerance. genetic linkage map with 198 simple sequence repeat (SSR) markers constructed. Six traits shoot dry weight (SW), root (RW), plant (PW), maximum length (RL), chlorophyll content (Chl), height (PH) were used to assess...
Abnormally developed endosperm strongly affects rice (Oryza sativa) appearance quality and grain weight. Endosperm formation is a complex process, although many enzymes related regulators have been identified, other factors remain largely unknown. Here, we report the isolation characterization of recessive mutation White Belly 1 (WB1), which regulates development, using modified MutMap method in mutant wb1. The wb1 develops white-belly abnormal starch granules inner portion white grains....
ABSTRACT Unraveling the mechanisms behind plant growth and immunity contributes to effective crop improvement. Membrane attack complex/perforin (MACPF) domain proteins play vital roles in innate adaptive vertebrates; however, their molecular functions plants remain largely unexplored. Here, we isolated characterized a rice mutant, Oryza sativa constitutively activated cell death 1 ( oscad1 ), which exhibited lesion mimic phenotype inhibition with increased death, elevated ROS accumulation,...
Rice (Oryza sativa L.) is a staple crop for nearly half of the global population and one China’s most extensively cultivated cereals. Heading date, critical agronomic trait, determines regional seasonal adaptability rice varieties. In this study, series mutants (elh5 to elh12) exhibiting extremely late heading under both long-day (LD) short-day (SD) conditions were identified from an ethyl methanesulfonate (EMS) mutant library. Using MutMap map-based cloning, causative gene was as novel...
Source size, sink size and heading date (HD) are three important classes of traits that determine the productivity rice. In this study, a set recombinant inbred lines (RILs) derived from cross between an elite indica line Big Grain1 (BG1) japonica Xiaolijing (XLJ) were used to map quantitative trait loci (QTLs) for source–sink date. Totally, thirty-one QTLs source twenty-two four seven QTL clusters which included multiple identified in environmental trials. Thirty could be consistently...
Pyrimidine nucleotides are important metabolites that building blocks of nucleic acids, which participate in various aspects plant development. Only a few genes involved pyrimidine metabolism have been identified rice and the majority their functions remain unclear. In this study, we used map-based cloning strategy to isolate UMPK gene rice, encoding UMP kinase phosphorylates form UDP, from recessive mutant with pale-green leaves. mutant, UDP content always decreased, while UTP fluctuated...
Plant architecture is dynamic as plants develop. Although many genes associated with specific plant components have been identified in rice, related to underlying changes remain largely unknown. Here, we two highly similar recombinant inbred lines (RILs) different architecture: RIL-Dynamic (D) and RIL-Compact (C). The of RIL-D characterized by 'loosetiller angle (tillering stage)-compact (heading stage)-loosecurved stem (maturing stage)' under natural long-day (NLD) conditions, heading...
Hybridization, a common process in nature, can give rise to vast reservoir of allelic variants. Combination these variants may result novel patterns gene action and is thought contribute heterosis. In this study, we analyzed genome-wide allele-specific expression (ASGE) the super-hybrid rice variety Xieyou9308 using RNA sequencing technology (RNA-Seq). We identified 9325 reliable single nucleotide polymorphisms (SNPs) distributed throughout genome. Nearly 68% were CT GA SNPs between R9308...
