A maize (Zea mays L. subsp. mays) diversity panel consisting of 26 maize lines exhibiting a wide range of cell-wall properties and responses to hydrolysis by cellulolytic enzymes was employed to investigate the relationship between cell-wall properties, cell-wall responses to mild NaOH pre-treatment, and enzymatic hydrolysis yields. Enzymatic hydrolysis of the cellulose in the untreated maize w...
Maize (Zea mays L. ssp. mays), one of the most important agricultural crops in the world, originated by hybridization of two closely related progenitors. To investigate the fate of its genes after tetraploidization, we analyzed the sequence of five duplicated regions from different chromosomal locations. We also compared corresponding regions from sorghum and rice, two important crops that have...
We measured sequence diversity in 21 loci distributed along chromosome 1 of maize (Zea mays ssp. mays L.). For each locus, we sequenced a common sample of 25 individuals representing 16 exotic landraces and nine U.S. inbred lines. The data indicated that maize has an average of one single nucleotide polymorphism (SNP) every 104 bp between two randomly sampled sequences, a level of diversity hig...
The phosphatidylethanolamine-binding proteins (PEBPs) represent an ancient protein family found across the biosphere. In animals they are known to act as kinase and serine protease inhibitors controlling cell growth and differentiation. In plants the most extensively studied PEBP genes, the Arabidopsis (Arabidopsis thaliana) FLOWERING LOCUS T (FT) and TERMINAL FLOWER1 (TFL1) genes, function, re...
AbstractThis essay explores the intersection of race science and plant taxonomy in creation evolutionary taxonomies (phylogenies) populations Zea mays, also known as maize or corn. Fol...
in order to study the intercropping effects of maize (zea mays l.) and bean (phaseolus vulgaris l.) and evaluating effect of intercropping on weed biomass, a field experiment was conducted at the agricultural research station, payamenoor university of nagadeh,west- azarbayjan, iran during growing season of 2009-2010. the experiment was laid out as randomized complete block design with three rep...
Submitted February 22, 1988 Accession no.X07041 Cytoplasmic male sterility (cms) in maize (Zea mays L.) is correlated with alterations in the mitochondrial genome. Four genetically distinct cytoplasms exist: N (normal) in which fertile pollen develops, and S, C and T in which pollen fails to develop [4,5]. Cms-S is characterized [4] by two ( free replicating elements, S-l (6.4 kb) and S-2 (5.2 ...
Maize (Zea mays L.)–legume intercropping is common cropping system among smallholder farmers in West Africa. However, little known about the income risk reduction associated with maize–legume strip A 3-yr study was conducted Upper and Northern regions of Ghana to determine effect on productivity, income, using a randomized complete block design five replications each region. Seven treatments we...
The transfer of mitochondrial DNA (mtDNA) into nuclear genomes is a regularly occurring process that has been observed in many species. Few studies, however, have focused on the variation of nuclear-mtDNA sequences (NUMTs) within a species. This study examined mtDNA insertions within chromosomes of a diverse set of Zea mays ssp. mays (maize) inbred lines by the use of fluorescence in situ hybri...
We investigate the interplay between genetic diversity and recombination in maize (Zea mays ssp. mays). Genetic diversity was measured in three types of markers: single-nucleotide polymorphisms, indels, and microsatellites. All three were examined in a sample of previously published DNA sequences from 21 loci on maize chromosome 1. Small indels (1-5 bp) were numerous and far more common than la...
