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, ...

Differential performance and parasitism of caterpillars on maize inbred lines with distinctly different herbivore-induced volatile emissions
(Public Library of Science, 2012)
Plant volatiles induced by insect feeding are known to attract natural enemies of the herbivores. Six maize inbred lines that showed distinctly different patterns of volatile emission in laboratory assays were planted in ...

Cloning and characterization of maize miRNAs involved in responses to nitrogen deficiency
(Public Library of Science, 2012)
Although recent studies indicated that miRNAs regulate plant adaptive responses to nutrient deprivation, the functional significance of miRNAs in adaptive responses to nitrogen (N) limitation remains to be explored. To ...

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 ...

Joint QTL linkage mapping for multiple-cross mating design sharing one common parent
(Public Library of Science, 2011)
Nested association mapping (NAM) is a novel genetic mating design that combines the advantages of linkage analysis and association mapping. This design provides opportunities to study the inheritance of complex traits, but ...

Comparative SNP and haplotype analysis reveals a higher genetic diversity and rapider LD decay in tropical than temperate germplasm in maize
(Public Library of Science, 2011)
Understanding of genetic diversity and linkage disequilibrium (LD) decay in diverse maize germplasm is fundamentally important for maize improvement. A total of 287 tropical and 160 temperate inbred lines were genotyped ...

Strategies to subdivide a target population of environments: Results from the CIMMYT-led maize hybrid testing programs in Africa
(Crop Science Society of America (CSSA), 2012)
To develop stable and high-yielding maize (Zea mays L.) hybrids for a diverse target population of environments (TPE), breeders have to decide whether greater gains result from selection across the undivided TPE or within ...

Sources of resistance to the maize weevil Sitophilus Zeamais in tropical maize
(Canadian Center of Science and Education, 2012)
The maize weevil, Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae), is among the major storage pests that enhance food insecurity among maize farmers. New sources of resistance to the maize weevil are critical ...
Article
Crops that feed the world 6. Past successes and future challenges to the role played by maize in global food security
(Springer Verlag, 2011)
Maize is one of the most important food crops in the world and, together with rice and wheat, provides at least 30% of the food calories to more than 4.5 billion people in 94 developing countries. In parts of Africa and ...
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, ...
