A genome-wide survey of maize lipid-related genes: Candidate genes mining, digital gene expression profiling and co-location with QTL for maize kernel oil
Lipids play an important role in plants due to their abundance and their extensive participation in many metabolic processes. Genes involved in lipid metabolism have been extensively studied in Arabidopsis and other plant ...
Genetic association mapping identifies single nucleotide polymorphisms in genes that affect abscisic acid levels in maize floral tissues during drought
(Oxford University Press; Society for Experimental Biology, 2011)
In maize, water stress at flowering causes loss of kernel set and productivity. While changes in the levels of sugars and abscisic acid (ABA) are thought to play a role in this stress response, the mechanistic basis and ...
Genetic analysis of QTL affecting recombination frequency in whole genome of maize and rice
Objective: Recombination plays an important role in species evolution as well as plant and animal breeding. Here, the number of crossover breakpoints was used as a trait to map the QTL controlling recombination of genomes. ...
Identification and characterization of CACTA transposable elements capturing gene fragments in maize
Transposable elements (TEs)-mediated gene sequence movement is thought to play an important role in genome expansion and origin of genes with novel functions. In this study, a gene, HGGT, involved in vitamin E synthesis ...
Molecular characterization of global maize breeding germplasm based on genome-wide single nucleotide polymorphisms
Characterization of genetic diversity is of great value to assist breeders in parental line selection and breeding system design. We screened 770 maize inbred lines with 1,034 single nucleotide polymorphism (SNP) markers ...
Validation of the effects of molecular marker polymorphisms in LcyE and CrtRB1 on provitamin A concentrations for 26 tropical maize populations
(Springer Verlag, 2012)
Vitamin A deficiency (VAD) compromises immune function and is the leading cause of preventable blindness in children in many developing countries. Biofortification, or breeding staple food crops that are rich in micronutrients, ...
QTL mapping for milling, gluten quality, and flour pasting properties in a recombinant inbred line population derived from a Chinese soft x hard wheat cross
Improvement of processing quality is important for various wheat-based end products. A recombinant inbred line (RIL) population derived from a cross between the Chinese wheat cvv. PH82-2 (hard) and Neixiang 188 (soft) was ...
An 11-bp insertion in Zea mays fatb reduces the palmitic acid content of fatty acids in Maize grain
(Public Library of Science, 2011)
The ratio of saturated to unsaturated fatty acids in maize kernels strongly impacts human and livestock health, but is a complex trait that is difficult to select based on phenotype. Map-based cloning of quantitative trait ...
Genetic characterization of a core set of a tropical maize race Tuxpeño for further use in maize improvement
(Public Library of Science, 2012)
The tropical maize race Tuxpeño is a well-known race of Mexican dent germplasm which has greatly contributed to the development of tropical and subtropical maize gene pools. In order to investigate how it could be exploited ...
Genetic characterization and linkage disequilibrium estimation of a global maize collection using SNP markers
(Public Library of Science, 2009)
A newly developed maize Illumina GoldenGate Assay with 1536 SNPs from 582 loci was used to genotype a highly diverse global maize collection of 632 inbred lines from temperate, tropical, and subtropical public breeding ...
