Cloning and expression analysis of hemoglobin genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis).
With the exception of barley and rice, little is known about the existence of hemoglobins (Hbs) in cereals. This work reports the cloning and analysis of hb genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis). Coding sequences of maize and teosinte hb genes (hbm and hbt, respectively) are highly similar to each other and are interrupted by three introns located at ide...

متن کاملMajor regulatory genes in maize contribute to standing variation in teosinte (Zea mays ssp. parviglumis).
In plants, many major regulatory genes that control plant growth and development have been identified and characterized. Despite a detailed knowledge of the function of these genes little is known about how they contribute to the natural variation for complex traits. To determine whether major regulatory genes of maize contribute to standing variation in Balsas teosinte we conducted association...
متن کاملPopulation genetics of duplicated disease-defense genes, hm1 and hm2, in maize (Zea mays ssp. mays L.) and its wild ancestor (Zea mays ssp. parviglumis).
Plant defense genes are subject to nonneutral evolutionary dynamics. Here we investigate the evolutionary dynamics of the duplicated defense genes hm1 and hm2 in maize and its wild ancestor Zea mays ssp. parviglumis. Both genes have been shown to confer resistance to the fungal pathogen Cochliobolus carbonum race 1, but the effectiveness of resistance differs between loci. The genes also displa...
متن کاملPopulation structure and its effects on patterns of nucleotide polymorphism in teosinte (Zea mays ssp. parviglumis).
Surveys of nucleotide diversity in the wild ancestor of maize, Zea mays ssp. parviglumis, have revealed genomewide departures from the standard neutral equilibrium (NE) model. Here we investigate the degree to which population structure may account for the excess of rare polymorphisms frequently observed in species-wide samples. On the basis of sequence data from five nuclear and two chloroplas...
