Salinity is a stressful environmental factor that limits the productivity of crop plants, and roots form major interface between plants various abiotic stresses. Rice salt-sensitive its polyploid shows advantages in terms stress resistance. The objective this study was to investigate effects genome duplication on rice root resistance salt stress.Both diploid (HN2026-2x Nipponbare-2x) their corresponding tetraploid (HN2026-4x Nipponbare-4x) were cultured half-strength Murashige Skoog medium...
Heterosis and polyploidy have an overwhelming influence on plant evolution. Recently, polyploid rice hybrids been used to breed new varieties because they combine the advantages of both heterosis polyploidy. In this study, we generated six lines: autotetraploid their parents, diploid donors, donors. To investigate molecular mechanism controlling effects hybridization polyploidization, performed bisulfite RNA sequencing young panicles at pollen meiosis stage compare DNA metabolomes...
Abstract Background Rice is not only an essential food but also a source of high quality protein. Polyploidy evolutionary trajectory in plants, and enhancing glutelin by polyploidization attractive strategy for improving the nutritional value rice seeds presents great potential commercial rice. Elucidating mechanisms underlying synthesis accumulation tetraploid significance. Results To enhance rice, we developed evaluated contents various nutrient elements mature seeds. The results revealed...
Male sterile lines play an important role in the utilization of heterosis. To explore and exploit heterosis polyploid hybrid rice, two photoperiod- thermo-sensitive genic male PS006 PS012, were bred via chromosome doubling, complex hybridization self-breeding. The characteristics these lines, including agronomic traits, growth, development, fertility transformation combining ability, investigated. Both had good flowering habits, a high outcrossing rate, obvious alterations abilities. Their...
The meiotic processes of most polyploid rice (Oryza sativa) are genetically abnormal, leading to low pollen fertility, which results in seed set rates. Some meiosis stability (PMeS) lines with high rates have been bred but their mechanisms remain unknown. In this study, we investigated the function OsMND1 regulated meiosis. localized nucleus, and its expression level panicles PMeS line HN2026-4x was higher than HN2026-2x other without background. OsMND1's overexpression improved fertility...
Plant polyploidization is frequently associated with changes in nutrient contents. However, the possible contribution of metabolites to this change has not been investigated by characterizing metabolite contents diploid and tetraploid forms rice (Oryza sativa L.). We compared a group diploid-tetraploid japonica brown indica based on liquid chromatography-tandem mass spectrometry. In total, 401 were identified; these, between two groups, 180 showed opposite expression trends, but 221 same...
Polyploidy is a major force in plant evolution and the domestication of cultivated crops. The study aimed to explore relationship underlying mechanism between three-dimensional (3D) chromatin organization gene transcription upon rice genome duplication. 3D structures diploid (2C) autotetraploid (4C) were compared using high-throughput chromosome conformation capture (Hi-C) analysis. combined genetics, transcriptomics, whole-genome bisulfite sequencing (WGBS-seq) genomics approaches uncover...
Abstract BACKGROUND Indole, an important type of N ‐heterocyclic aromatic compound, is considered a toxic and odorous pollutant in coking municipal wastewater. For efficient bioremediation indole‐containing wastewater, indole‐degrading bacterial strain JW was isolated from activated sludge this study. The indole biodegradation characteristics the whole‐genome sequence were also determined. RESULTS Strain JW, capable utilizing as sole carbon nitrogen source, identified Acinetobacter sp. based...
Allopolyploid breeding is an efficient technique for improving the low seed setting rate of autotetraploids in plant and one most promising methods. However, there have been few comprehensive studies posttranscriptional mechanism allopolyploids.By crossing cultivated rice (Oryza sativa, genome AA) with wild punctata, BB), we created hybrid lines different ploidy compositions [diploid F01 (AB), allotetraploid F02 (AABB) F03 (AAAB)]. The genetic differences hybrids allopolyploid dominance were...
Abstract Oryza punctata , a wild relative of cultivated rice, belongs to the BB genome . Interspecific hybrids (CW008, AB) between sativa (2 n = 24 AA) and O BB) were obtained using embryo rescue technique. Synthetic allopolyploid (DCW008, AABB) produced through chromosome doubling by colchicine. Hybrids overcame many traits except shattering awn. The synthetic amphiploid plants showed obvious superiority in growth production. CW008 completely infertile but DCW008 had better seed set after...
Grain size is a key factor in determining rice (Oryza sativa) yield, and exploring new pathways to regulate grain has immense potential improve yield. In this study, we report that OsCBL5 encodes calcineurin B subunit protein significantly promotes weight. oscbl5 plants produced obviously smaller lighter seeds. We further revealed by affecting cell expansion the spikelet hull. Biochemical analyses demonstrated CBL5 interacts with CIPK1 PP23. Furthermore, double triple mutations were induced...
Polyploid rice and its reverted diploid show rich phenotypic variation strong heterosis, showing great breeding value. However, the genomic differences among tetraploids, counterpart common diploids, tetraploid-revertant hybrid descendants are unclear. In this work, we bred a new excellent two-line variety,
Seed of rice is an important strategic resource for ensuring the security China's staple food. deterioration as a result senescence major problem during seed storage, which can cause economic losses. Screening among accessions in germplasm resources traits such slow and increased longevity storage is, therefore, great significance. However, studies on delayed have been based mostly diploid to date. Despite better tolerance verified by artificial aging treatment polyploid seed, properties...
Abstract BACKGROUND Quinoline is an ubiquitous pollutant widely spread in the environment, which can be eliminated efficiently by microbial degradation. In this study, two quinoline‐degrading Comamonas sp. strains Z1 and Z3 were isolated from activated sludge, degradation characteristics genome annotation investigated detail. RESULTS Strain exhibited a superior capacity for quinoline degradation, could completely degrade 50–300 mg L −1 within 8–24 h, whereas strain required 14–36 h to remove...
DCW008, a synthetic allopolyploid rice (2n = 4X 48, AABB), was obtained from chromosome doubling of interspecific hybrids between Oryza sativa 24, AA) and O. punctata BB). The F1 backcross (BC1) were produced by crossing DCW008 as female parent with high seed set tetraploid Sg99012 - AAAA). BC1F1 BC1F2 overcame many the wild-type traits DCW008; they had yellow-hulled grains, ranged 0% to 71.31% grain morphology similar that cultivated rice. Variable numbers chromosomes observed in pollen...
