Sorghum (Sorghum bicolor (L.) Moench) is an important crop originated in Africa that shows susceptibility to herbivores. In this study, we identified two sorghum genotypes with highly contrasting levels of stem damage caused by the caterpillars Asian borer (Ostrinia furnacalis Guenée). Recombinant inbred lines (RILs) from genetic cross between resistant (BTx623) and susceptible (NOG) were used ...

Dissipation of petroleum contaminants in the rhizosphere is likely the result of enhanced microbial degradation. Plant roots may encourage rhizosphere microbial activity through exudation of nutrients and by providing channels for increased water flow and gas diffusion. Phytoremediation of crude oil in soil was examined in this study using carefully selected plant species monitored over specifi...

The infrageneric phylogeny and temporal divergence of Sorghum were explored in the present study. Sequence data of two low-copy nuclear (LCN) genes, phosphoenolpyruvate carboxylase 4 (Pepc4) and granule-bound starch synthase I (GBSSI), from 79 accessions of Sorghum plus Cleistachne sorghoides together with those from outgroups were used for maximum likelihood (ML) and Bayesian inference (BI) an...

Germination and seedling growth of major cereals treated with Moringa oleifera leaf extracts was investigate at University of Zambia. Aqueous extract of Moringa oleifera at the ratio of 1:10 (w/v) were sprayed on seed of maize (Zea mays. L.), rice (Oryzae sativa.L.), sorghum (Sorghum bicolor. L.) and wheat (Triticum Aestivum. L.) in a growth room at 25C for 14 days. The data were subjected to a...

The Ma3 gene is one of six genes that regulate the photoperiodic sensitivity of flowering in sorghum (Sorghum bicolor [L.] Moench). The ma3R mutation of this gene causes a phenotype that is similar to plants that are known to lack phytochrome B, and ma3 sorghum lacks a 123-KD phytochrome that predominates in light-grown plants and that is present in non-ma3 plants. A population segregating for ...

Dhurrin, I ((S)-p-hydroxymandelonitrile-beta-D-glucopyranoside), and taxiphyllin, II (the (R) epimer), occur in the genera Sorghum and Taxus, respectively. Both derive biosynthetically from L-tyrosine via the hydroxylation of p-hydroxyphenylacetonitrile, III. (3R)- and (3S)-L-[3-3H1]tyrosine, prepared by enzymic hydroxylation of the corresponding phenylalanines, were fed separately to shoots fr...

The highly photosynthetic-efficient C4 grasses, such as switchgrass (Panicum virgatum), Miscanthus (Miscanthusxgiganteus), sorghum (Sorghum bicolor) and maize (Zea mays), are expected to provide abundant and sustainable resources of lignocellulosic biomass for the production of biofuels. A deeper understanding of the synthesis, deposition and hydrolysis of the distinctive cell walls of grasses ...

to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...
