Open AccessTwo divergent haplotypes from a highly heterozygous lychee genome suggest independent domestication events for early and late-maturing cultivars
Lychee is an exotic tropical fruit with a distinct flavor. The genome of cultivar ‘Feizixiao’ was assembled into 15 pseudochromosomes, totaling ~470 Mb. High heterozygosity (2.27%) resulted in two complete hap...

Identification of SNP markers associated with soybean fatty acids contents by genome-wide association analyses
Composition of fatty acids (FAs) in soybean seed is important for the quality and uses of soybean oil. Using gas chromatography, we have measured soybean FAs profiles of 621 soybean accessions (maturity groups...

Testing methods and statistical models of genomic prediction for quantitative disease resistance to Phytophthora sojae in soybean [Glycine max (L.) Merr] germplasm collections
Genomic prediction of quantitative resistance toward Phytophthora sojae indicated that genomic selection may increase breeding efficiency. Statistical model and marker set had minimal effect on genomic prediction...

Use of genomic selection in breeding rice (Oryza sativa L.) for resistance to rice blast (Magnaporthe oryzae)
Rice blast (RB), caused by the fungal pathogen Magnaporthe oryzae, is a major disease in rice (Oryzae sativa L.) with resistance controlled by major and minor genes. Genomic selection (GS) is a breeding technolog...

Open AccessGenome-wide association study of seed protein, oil and amino acid contents in soybean from maturity groups I to IV
Genomic regions associated with seed protein, oil and amino acid contents were identified by genome-wide association analyses. Geographic distributions of haplotypes indicate scope of improvement of these traits.

Characterization of 40 soybean (Glycine max) promoters, isolated from across 5 thematic gene groups
Gene expression in plants is primarily modulated by the promoter region, which is located upstream of the gene coding region. Specific regulatory sequences within the promoter region contribute to the strength...

Open AccessGenome-wide association map** of partial resistance to Phytophthora sojae in soybean plant introductions from the Republic of Korea
Phytophthora root and stem rot is one of the most yield-limiting diseases of soybean [Glycine max (L.) Merr], caused by the oomycete Phytophthora sojae. Partial resistance is controlled by several genes and, comp...

Open AccessIdentification and map** of quantitative trait loci (QTL) conferring resistance to Fusarium graminearum from soybean PI 567301B
A major novel QTL was identified in a recombinant inbred line population derived from a cross of ‘Wyandot’ × PI 567301B for Fusarium graminearum, a seed and ...

Isolation and characterization of novel Agrobacterium strains for soybean and sunflower transformation
Although many laboratories routinely use Agrobacterium for the generation of transgenic plants, only a few bacterial strains are widely used. For this research, new Agrobacterium strains were isolated from galls ...

A high-resolution genetic linkage map of soybean based on 357 recombinant inbred lines genotyped with BARCSoySNP6K
The objective of this study was to construct a high-density genetic map of soybean (Glycine max L. Merr) using a high-throughput single nucleotide polymorphism (SNP) genoty** on 357 F7 recombinant inbred lines...

Article
Development and optimization of agroinfiltration for soybean
Agroinfiltration is an efficient method to study transgene expression in plant tissue. In this study, sonication followed by vacuum infiltration is shown to increase agroinfil...

Article
Joint linkage QTL analyses for partial resistance to Phytophthora sojae in soybean using six nested inbred populations with heterogeneous conditions
Partial resistance to Phytophthora sojae in soybean is controlled by multiple quantitative trait loci (QTL). With traditional QTL map** approaches, power to detect such QTL, frequently of small effect, can be l...

An intra-specific linkage map of lettuce (Lactuca sativa) and genetic analysis of postharvest discolouration traits
Minimally processed salad packs often suffer from discolouration on cut leaf edges within a few days after harvest. This limits shelf life of the product and results in high wastage. Recombinant inbred lines (...

Open AccessNovel quantitative trait loci for partial resistance to Phytophthora sojae in soybean PI 398841
Phytophthora root and stem rot caused by Phytophthora sojae Kaufmann and Gerdemann is one of the most severe soybean [Glycine max (L.) Merr] diseases in the USA. Partial resistance is as effective in managing thi...

Open AccessHybridization between crops and wild relatives: the contribution of cultivated lettuce to the vigour of crop–wild hybrids under drought, salinity and nutrient deficiency conditions
With the development of transgenic crop varieties, crop–wild hybridization has received considerable consideration with regard to the potential of transgenes to be transferred to wild species. Although many st...

Open AccessCrop to wild introgression in lettuce: following the fate of crop genome segments in backcross populations
After crop-wild hybridization, some of the crop genomic segments may become established in wild populations through selfing of the hybrids or through backcrosses to the wild parent. This constitutes a possible...

The inheritance of resistance to Verticillium wilt caused by race 1 isolates of Verticillium dahliae in the lettuce cultivar La Brillante
Verticillium wilt of lettuce caused by Verticillium dahliae can cause severe economic damage to lettuce producers. Complete resistance to race 1 isolates is available in Lactuca sativa cultivar (cv.) La Brillante...

Open AccessAssociation map** and marker-assisted selection of the lettuce dieback resistance gene Tvr1
Lettuce (Lactuca saliva L.) is susceptible to dieback, a soilborne disease caused by two viruses from the family Tombusviridae. Susceptibility to dieback is widespread in romaine and leaf-type lettuce, while mode...

The genomic architecture of disease resistance in lettuce
Genbank and The Compositae Genome Project database, containing over 42,000 lettuce unigenes from Lactuca sativa cv. Salinas and L. serriola accession UC96US23 were mined to identify 702 candidate genes involved i...
