Mapping QTLs for polyphenol oxidase activity in a DH population from common wheat
(Institute of Crop Sciences, 2005)
The polyphenol oxidase ( PPO) activity is a major factor to cause an undesirable brown discoloration of wheat based end products during processing or storage. A double haploid (DH) population with 71 lines derived from ...

Relationship, evolutionary fate and function of two maize co-orthologs of rice GW2 associated with kernel size and weight
(BioMed Central, 2010)
Background: In rice, the GW2 gene, found on chromosome 2, controls grain width and weight. Two homologs of this gene, ZmGW2-CHR4 and ZmGW2-CHR5, have been found in maize. In this study, we investigated the relationship, ...

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 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 ...

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 ...

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 ...

Metabolome-based genome-wide association study of maize kernel leads to novel biochemical insights
(Nature Research, 2014)
Plants produce a variety of metabolites that have a critical role in growth and development. Here we present a comprehensive study of maize metabolism, combining genetic, metabolite and expression profiling methodologies ...
Article
Validation of the effects of molecular marker polymorphisms in LcyE and CrtRB1 on provitamin A concentrations for 26 tropical maize populations
(Springer, 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, ...
Article
Advances in maize genomics and their value for enhancing genetic gains from breeding
(Hindawi Publishing Corporation, 2009)
Maize is an important crop for food, feed, forage, and fuel across tropical and temperate areas of the world. Diversity studies at genetic, molecular, and functional levels have revealed that, tropical maize germplasm, ...

Quantitative trait loci mapping for adult-plant resistance to powdery mildew in Chinese wheat cultivar Bainong 64
(American Phytopathological Society (APS), 2009)
Adult-plant resistance (APR) is an effective means of controlling powdery mildew in wheat. In the present study, 406 simple-sequence repeat markers were used to map quantitative trait loci (QTLs) for APR to powdery mildew ...
