Relay intercropping systems with rice cultivars (WAB450-24-3-2-P18-HB (V4) and WAB56-50), the competitive Cajanus cajan and the weakly competitive Stylosanthes hamata were evaluated in the tropical savanna zone in Côte d’Ivoire. The INTERCOM model for competition served for data analysis and understanding of the system based on phenological, physiological and morphological characteristics of th...

Sickle cell disease (SCD) is a genetic blood disorder that affects the shape and transportation of red blood cells (RBCs) in blood vessels, leading to various clinical complications. Many drugs that are available for treating the disease are insufficiently effective, toxic, or too expensive. Therefore, there is a pressing need for safe, effective, and inexpensive therapeutic agents from indigen...

Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...

Genetic diversity among and between 16 cultivars of pigeonpea (Cajanus cajan (L) Millsp.) and its wild relatives (C. albicans and C. lineatus) analysed using RAPD. Twenty two random primers with an average of 71.2% polymorphism produced 151 polymorphic bands. Cluster analysis based on these 151 RAPD markers revealed relatively low level (0.434 0.714) of genetic diversity among cultivars and hig...

Studies were undertaken to identify pigeonpea, Cajanus cajan (L.) Millspaugh and the wild relative of pigeonpea, Cajanus scarabaeoides (L.) (accession ICPW 125,) genotypes that are hospitable to the pod borer, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) larval parasitoid, Campoletis chlorideae Uchida (Hymenoptera: Ichneumonidae) for the management of this pest in pigeonpea based crop...

Whole-genome duplication events (polyploidy events) and gene loss events have played important roles in the evolution of legumes. Here we show that the vast majority of Hsf gene duplications resulted from whole genome duplication events rather than tandem duplication, and significant differences in gene retention exist between species. By searching for intraspecies gene colinearity (microsynten...

A field plots experiment was carried to investigate the influence of soil applications of neem-based (Achook and Nimbidin) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living and plant-pathogenic nematode populations and crop productivity. Data regarding the results showed that all the treatments significantly decreased the number of plant-paras...

It has been difficult to extract a good quality total RNA from the plant parts (such as seeds) which contain high levels of phenolic compounds, carbohydrates and other compounds that bind and/or co-precipitate with RNA. A simple, rapid and efficient method for isolating total RNA from polyphenols and polysaccharide rich plant tissues has been developed. Seeds of leguminosae family were chosen f...

This review summarizes the studies carried on the development of potentiometric urea biosensor in laboratory using urease from Cajanus cajan (local Arhar). The enzyme used was free without any immobilisation over matrix. The electrode used egg membrane or cellophane paper making ionic diffusion possible across the two solutions. Underlying the importance of this study is the fact that urea is t...
