Genetic distances across the a1-sh2 interval varied threefold in three near-isogenic stocks that carry structurally distinct teosinte A1 Sh2 haplotypes (from Z. mays spp. mexicana Chalco, Z. mays spp. parviglumis, and Z. luxurians) and a common maize a1::rdt sh2 haplotype. In each haplotype >85% of recombination events resolved in the proximal 10% of the approximately 130-kb a1-sh2 interval. Ev...

We analyzed the genetic basis of morphological differences between two wild species of teosinte (Zea diploperennis and Z. mays ssp. parviglumis), which are relatives of maize. These two species differ in a number of taxonomically important traits including the structure of the tassel (male inflorescence), which is the focus of this report. To investigate the genetic inheritance of six tassel tr...

Polycomb group (PcG) proteins play an important role in developmental and epigenetic regulation of gene expression in fruit fly (Drosophila melanogaster) and mammals. Recent evidence has shown that Arabidopsis homologs of PcG proteins are also important for the regulation of plant development. The objective of this study was to characterize the PcG homologs in maize (Zea mays). The 11 cloned Pc...

In the Republic of Benin, several plants, including Zea mays Linn (Z. mays) are used for treatment diabetes without any scientific studies showing their effectiveness. The objective this study is to investigate effects Z. leaves’ extracts on hyperglycaemic rabbits using Oral Glucose Tolerance Test (OGTT), 2 g/kg (D) + glucose and hepatic liberation. Phytochemical screening revealed that plant l...

The 1-deoxy-D-xylulose 5-phosphate synthase (DXS) enzyme catalyses the first biosynthetic step of the 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway. In plants the MEP pathway is involved in the synthesis of the common precursors to the plastidic isoprenoids, isopentenyl diphosphate and dimethylallyl diphosphate, in plastids. DXS is recognized as limiting this pathway and is a potential targ...

In order to evaluate influential mechanisms for photosynthetic processes on the yields of an intercropping system composed maize (Zea mays), Lupinus sp. and Melilotus albus, three treatments were designed conducted in southern Moravia (Czech Republic) form agronomy trials. The included sole (SM), with (ML) field melilot (MM). Zea mays monitored using several chlorophyll fluorescence techniques ...

The karyotype is a basic concept regarding the genome, fundamentally described by the number and morphological features of all chromosomes. Chromosome class, centromeric index, intra- and interchromosomal asymmetry index, and constriction localization are important in clinical, systematic and evolutionary approaches. In spite of the advances in karyotype characterization made over the last year...

BACKGROUND The species Zea mays includes both domesticated maize (ssp. mays) and its closest wild relatives known as the teosintes. While genetic and archaeological studies have provided a well-established history of Z. mays evolution, there is currently minimal description of its current and past distribution. Here, we implemented species distribution modeling using paleoclimatic models of the...

Mesophilic biogas production and substrate decomposition is one of the significant limiting steps in generation. The rate generation quality often affect viability systems. This study assessed potential for process catalysis using powdered Sorghum bicolor L., Zea mays, Pennisetum glaucum. kinetics processes were studied. Experiments conducted 1 m3 tubular batch reactors, where batches dosed wit...

A wealth of information on the patterns human subsistence and plant domestication has been generated from studies maize (Zea mays) starch granules. However, very little work conducted how size morphology those granules might change as a function water stress during growing season. In arid Southwest, role irrigation in is an essential parameter many foraging models. Our study seeks to determine ...
