Plant architecture attributes, such as plant height, ear and internode number, have played an important role in the historical increases grain yield, lodging resistance, biomass maize (Zea mays L.). Analyzing genetic basis of variation using high density QTL mapping will be benefit for breeding many traits. However, low molecular markers existing maps has limited efficiency accuracy mapping. Genotyping by sequencing (GBS) is improved strategy addressing a complex genome via next-generation...
Abstract Background Maize ( Zea mays L.) is one of the main agricultural crops with largest yield and acreage in world. However, maize germplasm very sensitive to low temperatures, mainly during germination, temperatures significantly affect plant growth crop yield. Therefore, identification genes capable increasing tolerance temperature has become necessary. Results In this study, fourteen phenotypic traits related seed germination were used assess genetic diversity through genome-wide...
Planting density is a major limiting factor for maize yield, and breeding tolerance has become an urgent issue. The leaf structure of the ear main that restricts planting yield composition. In this study, natural population 201 inbred lines was used genome-wide association analysis, which identified nine SNPs on chromosomes 2, 5, 8, 9, 10 were significantly associated with type structure. Further verification through qRT-PCR confirmed five candidate genes these SNPs, Zm00001d008651 gene...
<title>Abstract</title> Background Maize head smut, a severe fungal disease, poses significant threats to production, particularly in spring maize regions northern and eastern China. Mining smut resistant genes developing varieties are one of the most effective strategies for mitigating this disease. Results This study evaluated resistance 292 inbred lines through artificial inoculation over two years at same locations. Genome-wide association (GWAS) identified three consistent...
Rice black-streaked dwarf virus (RBSDV) causes maize rough disease (MRDD), which is a viral that significantly affects yields worldwide. Plants tolerate stress through transcriptional reprogramming at the alternative splicing (AS), transcriptional, and fusion gene (FG) levels. However, it unclear whether how AS FG interfere with in MRDD. In this study, we performed global profiling of on response to RBSDV compared changes. There are approximately 1.43 2.25 events per infected RBSDV....
The NAC gene family has transcription factors specific to plants, which are involved in development and stress response adaptation. In this study, ZmNAC89, an maize that plays a role saline-alkaline tolerance, was isolated characterized. ZmNAC89 localized the nucleus had transcriptional activation activity during vitro experiments. expression of strongly upregulated under saline-alkaline, drought ABA treatments. Overexpression transgenic Arabidopsis enhanced salt tolerance at seedling stage....
Abstract Good root growth in the early post-germination stages is an important trait for direct seeding rice, but its genetic control poorly understood. In this study, we examined architecture of variation primary length using a diverse panel 178 accessions. Four QTLs (qRL3, qRL6, qRL7, and qRL11) were identified genome-wide association studies. One candidate gene was validated major QTL qRL11, namely glucosyltransferase OsIAGLU. Disruption Osiaglu mutants reduced numbers lateral crown...
The environmental effects of genetically modified crops are now a global concern. It is important to monitor the potential impact transgenic corn after commercial release. In rhizosphere soil, plant roots interact with soil enzymes and microfauna, which can be affected by transgenes crops. To determine long-term cultivation, we conducted field study for 3 consecutive years (2018–2020) observed enzyme activities nematode populations in plots planted maize BQ-2, non-transgenic wild-type...
Soil salt-alkalization is a common yet critical environmental stress factor for plant growth and development. Discovering exploiting genes associated with alkaline tolerance in maize ( Zea mays L.) helpful improving resistance. Here, an association panel consisting of 200 lines was used to identify the genetic loci responsible tolerance-related traits seedlings. A total nine single-nucleotide polymorphisms (SNPs) their candidate were found be significantly using genome-wide study (GWAS). An...
Maize (Zea mays L.) is an important food crop planted across the world, and low-temperature stress can affect maize germination. Alternative splicing (AS) widely present in plants under abiotic stress; however, response of AS to remains unclear. In this study, a genome-wide analysis during low temperatures was performed. events were distributed on each chromosome, approximately 2.05-2.09 per gene. Seven genes only had low-temperature-resistant inbred lines. A total 278 KEGGs 46 GOs enriched...
Rice black-streaked dwarf virus (RBSDV), a Fijivirus, causes maize rough disease and rice in the summer maize-growing regions of Yellow Huai rivers, respectively, China. Nevertheless, diversification selection entire genome from S1 to S10 have not been illuminated. Molecular variation, evolution, conserved regions, other genomic properties were analyzed 21 RBSDV isolates (Zea mays L.) (Oryza sativa) hosts sampled nine geographic locations Low codon adaptation index values ranging 0.1878...
The development of salt-alkali tolerant genetically modified crops represents an important approach to increase grain production in saline-alkali soils. However, there is a paucity research on the impact such soil microbial diversity. This study aims investigate straw degradation betaine aldehyde dehydrogenase (BADH) transgenic maize BZ-136 and its effects chemical properties, fungal community composition, diversity ecological function compared non-transgenic Zheng58 straw. experiments were...
Rice black-streaked dwarf virus (RBSDV) and Southern rice (SRBSDV) cause maize rough disease (MRDD) (RBSDD) in China. RBSDV segment 8 (S8) contains the only deletion mutation genomes of these viruses, which are both members genus Fijivirus. To illuminate molecular differences between SRBSDV better understand evolution to determine is specifically associated with MRDD RBSDD each region, S8 was analyzed 66 isolates collected from 10 geographic locations China 14 sequences obtained National...
Rice black-streaked dwarf virus (RBSDV), a ds-RNA in Fijivirus genus with family Reoviridae, which is transmitted by the small brown planthopper, responsible for incidence of maize rough disease (MRDD) and rice (RBSDD). To understand variation evolution S5, unique fragment genome RBSDV encodes two partially overlapping ORFs (ORF5-1 ORF5-2), we analyzed 127 sequences from exhibiting symptoms dwarfism. The nucleotide diversity both ORF5-1 (π = 0.039) ORF5-2 0.027) was higher than that region...
