Grain size is a key determinant of grain weight and trait having critical influence on quality in rice. While increasing evidences are shown for the importance minor-effect QTL controlling complex traits, attention has not been given to until recently. In previous studies, five small effects were resolved long arm chromosome 1 using populations derived from indica rice cross Zhenshan 97///Zhenshan 97//Zhenshan 97/Milyang 46. One them, qTGW1.2c that was located 2.1-Mb region, targeted...
SUMMARY Chromium (Cr) pollution threatens plant development and growth. Application of melatonin (Mel) is emerging as an effective ally to resist stress, but how Mel ameliorates seed germination upon exposure heavy metals poorly understood. Here, we found (i) that priming with considerably alleviated Cr stress during rice ( Oryza sativa ) (ii) performance was significantly improved in suppressor the G2 allele skp1 OsSGT1 overexpression lines, while mutations and/or abscisic acid‐insensitive...
Rice is highly sensitive to temperature fluctuations. Recently, the frequent occurrence of high stress has heavily influenced rice production. Proper heading date in specific environmental conditions could ensure grain yield. greatly depends on accurate measurement changes, particularly day length and temperature. In contrary detailed understanding photoperiod pathway, little been known about how regulates genetic control heading. Near isogenic lines that were segregated for qHd1, developed...
A porous silicon (pSi) particle-based courier could deliver melatonin (MT) into pregerminated seeds by seed priming, which serves as an environmentally-friendly and sustainable method to improve nickel stress tolerance.
A total of 32 rice genotypes carrying different dwarf or semi-dwarf genes were inoculated with the fungus Fusarium moniliforme Sheldon treated 50 mg l-1 GA3 in order to select resources resistant bakanae disease from materials. The length elongated seedlings was measured, and percentage death after transplanting field also counted. significant correlation found between seedling injury by fungus. Rice materials gene such as sd1 not only sensitivity but susceptive disease. Materials d1...
Abstract Uniformity of stem height in rice directly affects crop yield potential and appearance, has become a vital index for improvement. In the present study, doubled haploid (DH) population, derived from cross between japonica Chunjiang 06 indica TN1 was used to analyze quantitative trait locus (QTL) three related traits panicle‐layer‐uniformity; that is, tallest panicle height, lowest layer disuniformity two locations: Hangzhou (HZ) Hainan (HN). A total 16 QTLs distributed on eight...
In this study, a total of 1047 insertion-deletion (InDel) primer pairs distributed across the rice genome were developed and experimentally validated.The designed based on InDel length polymorphisms between 93-11 (Oryza sativa ssp indica cv.) Nipponbare japonica cv.), aiming for utilization rice, or other inter-subspecific cultivars.The dispersed all 12 chromosomes, with one marker found every 371.3 kb average.The markers varied from 3 to 39 bp: 88.2% contained 6 25 bp, only 6.2% ≤5 5.6% ≥26...
Two rice doubled haploid (DH) populations derived from the crosses of ZYQ8/JX17 and CJ06/TN1 were used to detect quantitative trait loci (QTLs) for flag leaf length (FLL), width (FLW), angle (FLA) under long-day conditions in Hangzhou (subtropical zone) short-day Hainan (tropical zone), China.The four parents differed significantly all 3 traits.FLL was found be positively correlated with FLW 2 populations.A total 30 QTLs identified traits, a contribution phenotypic variation each QTL 4.49...
Five physiological and eleven yield traits of two pairs sister lines generated from a high generation with similar genetic background (SLs) for purple pericarp were investigated to explore the reasons behind low-yield production colored rice. Of five examined, except grain anthocyanin content, there generally trends between P (purple-pericarp) corresponding W (white-pericarp) over seasons (in year 2009 2010 separately). The results demonstrated that chlorophyll content flag leaves, net...
The number of grains per panicle significantly contributes to rice yield, but the regulatory mechanism remains largely unknown. Here, we reported a loss-of-function mutant, apical abortion 7 (paa7), which exhibited and degeneration spikelets on panicles during late stage young development in rice. High accumulations H2O2 paa7 caused programmed cell death (PCD) accompanied by nuclear DNA fragmentation spikelets. Map-based cloning revealed that 3 bp “AGC” insertion 4 “TCTC” deletion mutation...
A rice lesion mimic mutant, lm3, was obtained by the mutagenesis of an indica cultivar, 93-11, using γ-ray radiation. Brownish lesions appeared on leaves lm3 at young seedling stage and persisted until ripening stage. The mutant characterised a shorter plant height delayed heading compared with wild-type 93-11. genetic analysis indicated that phenotype controlled single recessive gene. Using simple sequence repeat (SSR) markers, target gene LM3 first located between marker RM5748 RM14906...
Temperature is an important environmental factor affecting heading date of rice. Despite its importance, genes responsible for temperature-sensitive in rice have remained elusive. Our previous study identified a quantitative trait locus qHd1 which advances under high temperatures. A 9.5-kb insertion was found the first intron OsMADS51 indica variety Zhenshan 97 (ZS97). However, function this natural variant controlling temperature sensitivity has not been verified. In study, we used...
