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...
Maize rough dwarf disease (MRDD) is a viral infection that results in heavy yield losses maize worldwide, particularly the summer maize-growing regions of China. MRDD caused by Rice black-streaked virus (RBSDV). In present study, analyses microRNAs (miRNAs), degradome, and transcriptome sequences were used to elucidate RBSDV-responsive pathway(s) maize. Genomic analysis indicated expression three non-conserved 28 conserved miRNAs, representing 17 known miRNA families 14 novel significantly...
Drought stress is seriously affecting the growth and production of crops, especially when agricultural irrigation still remains quantitatively restricted in some arid semi-arid areas. The identification drought-tolerant genes important for improving adaptability maize under stress. Here, we found that a new member actin-depolymerizing factor (ADF) family; ZmADF5 gene was tightly linked with consensus quantitative trait locus, significantly associated signals were detected through genome wide...
Northeast China (NEC) is a major spring maize (Zea mays L.) growing belt, and the outputs substantially influence national grain production. However, yield per unit area has little changes in recent years, partially due to lack of elite germplasm resources innovation. Therefore, this study aimed determine performance diverse populations NEC propose appropriate strategies for utilization broaden genetic base Chinese germplasm. Fifteen from International Maize Wheat Improvement Center (CIMMYT)...
Maize plant height related traits including height, ear and internode number are tightly linked with biomass, planting density, grain yield in the field. Previous studies have focused on understanding genetic basis of architecture per se, but combining ability remains poorly understood. In this study, 328 recombinant inbred lines were inter-group crossed two testers to produce 656 hybrids using North Carolina II mating design. Both parental evaluated summer maize-growing regions China 2015...
Waxy maize is prevalently grown in China and other countries due to the excellent characters economic value. However, its low content of lysine can't meet nutritional requirements humans livestock. In present study, we introgressed opaque2 (o2) allele into waxy line Zhao OP-6/O2O2 by using marker-assisted selection (MAS) technique successfully improved quality maize. Transcript abundance analysis indicated that wx1 expression levels had no difference between OP-6/o2o2 OP-6/O2O2. was...
Abstract Background Natural variations derived from both evolutionary selection and genetic recombination, presume to have important functions respond various abiotic stresses, which could be used improve drought tolerance via genomic selection. Results In the present study, NAC-encoding gene of ZmNAC080308 was cloned sequenced in 199 inbred lines maize. Phylogenetic analysis showed that is closely clusteredinto same group with other well-known NAC genes responding tolerance. total, 86 SNPs...
Tassel, the male reproductive organs in maize, its development is adversely affected by drought during tasseling. To determine tolerance mechanisms of tassel differentiation at transcriptome level, RNA-Seq was performed using RNA early developing from 10 maize inbred lines under well-watered (control) and drought-stressed conditions, respectively. Results showed that most active pathway for stress were related to metabolic regulation level. And some genes, encoding enzymes involved...
Starch biosynthesis in endosperm is a key process influencing grain yield and quality maize. Although number of starch biosynthetic genes have been well characterized, the mechanisms by which expression these regulated, especially regard to microRNAs (miRNAs), remain largely unclear.Sequence data for small RNAs, degradome, transcriptome maize at 15 25 d after pollination (DAP) from inbred lines Mo17 Ji419, exhibit distinct content granule structure, revealed mediation pathways miRNAs....
ABSTRACT Introgression of elite exotic maize ( Zea mays L.) germplasm into breeding programs would increase genetic variation within heterotic groups and counter the narrowing Chinese base. This study measured performance populations in northern China to allow use broaden base germplasm. Fifteen International Maize Wheat Improvement Center (CIMMYT) U.S. were testcrossed with Csyn 5, Cpop.11, Cpop.12, which represent Sipingtou, Lancaster Sure crop, Reid Yellow Dent subgroups, respectively....
Genomic prediction (GP) in plant breeding has the potential to predict and identify best-performing hybrids based on genotypes of their parental lines. In a GP experiment, 34 elite inbred lines were selected make 285 single-cross partial-diallel cross design. These represented mini-core collection Chinese maize germplasm comprised 18 from Stiff Stalk heterotic group 16 Non-Stiff group. The parents genotyped by sequencing phenotyped for nine yield yield-related traits at two locations summer...
