论文题目：Genetic background effects on QTL andQTL × environment interaction for yield and its component traits as revealed by reciprocalintrogression lines in rice

全部作者： Xiaoqian Wang, Yunlong Pang, Jian Zhang, Qiang Zhang, Yonghong Tao, Bo Feng, Tianqing Zheng, Jianlong Xu?, Zhikang Li

期刊名称：作物学报(英文版) 2014年第6期

论文摘要：QTLs for quantitative traits are influenced by genetic background (GB) and environment. Identification of QTL with GB independency and environmental stability is prerequisite for effective marker-assisted selection (MAS). In this study, QTLs and QTL × environment interactions affecting grain...[查看全部]

论文摘要：QTLs for quantitative traits are influenced by genetic background (GB) and environment. Identification of QTL with GB independency and environmental stability is prerequisite for effective marker-assisted selection (MAS). In this study, QTLs and QTL × environment interactions affecting grain yield per plant (GY) and its component traits, filled grain number per panicle (FGN), panicle number per plant (PN) and 1000-grain weight (TGW) across six environments were dissected using two sets of reciprocal introgression lines (ILs) derived from the cross Lemont × Teqing and SNP genotypic data.

论文摘要：Salt is an abiotic stress factor that strongly affects soybean growth and production. A single dominant gene has been shown to confer salt tolerance in the soybean cultivar Tiefeng 8. The objective of the present study was to genetically map the salt-tolerance gene in an F2:3 population and a recombinant inbred line (RIL) population derived from a cross between two cultivated soybeans, Tiefeng 8 (tolerant) and 85-140 (sensitive). The F2:3 families and RILs were treated with 200 mmol L?1 NaCl to evaluate salt tolerance.[返回]

论文摘要：Soybean genotypes show diverse physiological responses to drought, but specific physiological traits that can be used to evaluate drought tolerance have not been identified. In the present study we investigated physiological traits of soybean genotypes under progressive soil drying and rewetting, using a treatment mimicking field conditions. After a preliminary study with eight soybean genotypes, two drought-tolerant genotypes and one susceptible genotype were grown in the greenhouse and subjected to water restriction. [返回]

论文摘要：Miniature inverted-repeat transposable elements (MITEs) are a type of DNA transposon frequently inserted into promoters, untranslated regions (UTR), introns, or coding sequences of genes. We found a 276-bp tourist-like MITE insertion in the 3′-UTR of a 16.9 kDa small heat shock protein gene...[查看全部]

论文摘要：Miniature inverted-repeat transposable elements (MITEs) are a type of DNA transposon frequently inserted into promoters, untranslated regions (UTR), introns, or coding sequences of genes. We found a 276-bp tourist-like MITE insertion in the 3′-UTR of a 16.9 kDa small heat shock protein gene (TaHSP16.9-3A) on chromosome 3A of common wheat. Haplotype analysis revealed two haplotypes, sHSP-W (wild type without MITE insertion) and sHSP-M (mutant with MITE insertion), present in wheat germplasm. Both semiquantitative PCR and quantitative real-time PCR analyses showed increased transcription levels of TaHSP16.9-3A in sHSP-M compared with those of sHSP-W after heat treatment at 42 °C.[返回]

论文摘要：A field experiment was conducted to study the impact of the exclusion of the solar UV components on growth, photosynthesis and nitrogen metabolism in soybean (Glycine max) varieties PK-472, Pusa-24, JS 71-05, JS-335, NRC-7 and Kalitur. The plants were grown in specially designed UV exclusion...[查看全部]

论文摘要：A field experiment was conducted to study the impact of the exclusion of the solar UV components on growth, photosynthesis and nitrogen metabolism in soybean (Glycine max) varieties PK-472, Pusa-24, JS 71-05, JS-335, NRC-7 and Kalitur. The plants were grown in specially designed UV exclusion chambers wrapped with filters to exclude UV-B or UV-A/B and transmitted all UV. Exclusion of UV significantly enhanced the growth of the aerial parts as well as the growth of the below ground parts in all of the six soybean varieties.[返回]

论文摘要：The polymerase chain reaction (PCR) is particularly useful for plant pathogen detection. In the present study, multiplex PCR and SYBR Green real-time PCR were developed to facilitate the simultaneous detection of three important rice pathogens, Xanthomonas oryzae pv. oryzae, X. oryzae pv. oryzicola, and Burkholderia glumae. The unique PCR primer sets were designed from portions of a putative glycosyltransferase gene of X. oryzae pv. oryzae, an AvrRxo gene of X. oryzae pv. oryzicola, and an internal transcribed spacer (ITS) sequence of B. glumae.

论文摘要：Breeding of forage maize should combine improvement achieved for grain with the specific needs of forage hybrids. Production stability is important when maize is used for silage if the planting area is not in the ideal agronomic environment. The objectives of the present research were: (i) to quantify environmental and genetic and their interaction effects on maize silage traits;(ii) to identify possible heterotic groups for forage aptitude and suggest the formation of potential heterotic patterns, and (iii) to identify suitable inbred line combinations for producing hybrids with forage aptitude.

论文摘要：High-density genetic markers are required for genotyping and linkage mapping in identifying genes from crops with complex genomes, such as barley. As the most common variation, single nucleotide polymorphisms (SNPs) are suitable for accurate genotyping by using the next-generation sequencing (NGS) technology. Reduced representation libraries (RRLs) of five barley accessions and one mutant were sequenced using NGS technology for SNP discovery. Twenty million short reads were generated and the proportion of repetitive sequences was reduced by more than 56%. [返回]
