متن کاملRotational Effects Of Legumes On Maize Yield
Application of inadequate quantities of fertilizers limits maize yield in Ghana. Experiments were conducted to determine the effect of Mucuna pruriens, Canavalia ensiformis, and soybean (Glycine max (L.) Merrill) on maize (Zea mays L.) grain yield under 4 mineral fertilizer N levels in a rotational system. The legumes were established in April of 1996 and 1997 at Ejura in the forest-savanna tra...
متن کاملUpdate on ureide degradation in legumes.
Warm season N2-fixing legumes move fixed N from the nodules to the aerial portions of the plant primarily in the form of ureides, allantoin and allantoate, oxidation products of purines synthesized de novo in the nodule. Ureides are also products of purine turnover in senescing tissues, such as seedling cotyledons. A combination of biochemical and molecular approaches in both crop and model spe...
متن کاملUpdate on Nematodes: Sophisticated Parasites of Legumes Nematodes. Sophisticated Parasites of Legumes
From an agronomic perspective, the interactions of phytoparasitic nematodes with leguminous crops can be devastating (Barker, 1998). On a cellular and molecular level, the complexities of the interactions of these microscopic worms with legumes are comparable to those of well-known symbionts (Mathesius, 2003). Because of their agricultural importance, the soybean cyst nematode Heterodera glycin...
متن کاملUpdate on Comparative Genomics of Legumes Bridging Model and Crop Legumes through Comparative Genomics
The Fabaceae, or legumes, constitute the third largest family of flowering plants, comprising more than 650 genera and 18,000 species (Polhill and Raven, 1981). Economically, legumes represent the second most important family of crop plants after Poaceae (grass family), accounting for approximately 27% of the world’s crop production (Graham and Vance, 2003). On a worldwide basis, legumes contri...
