In natural environments, the development of plants depends on interactions they maintain with their environment, in particular soil microorganisms such as arbuscular mycorrhizal fungi, especially since used inputs is scarce by majority farmers Côte d’Ivoire. The present study was carried out to endomycorrhizogenic potential soils which tomato, cashew and banana are grown. Place Duration Study: ...

Cowpea is an important grain legume crop of Africa, Latin America, and Southeast Asia. Leaf curl and golden mosaic diseases caused by Mungbean yellow mosaic India virus (MYMIV) have emerged as most devastating viral diseases of cowpea in Southeast Asia. In this study, we employed RNA interference (RNAi) strategy to control cowpea-infecting MYMIV. For this, we generated transgenic cowpea plants ...

Cowpea (V. unguiculata L. Walp) is a climate resilient legume crop important for food security. Cultivated cowpea (V. unguiculata L) generally comprises the bushy, short-podded grain cowpea dominant in Africa and the climbing, long-podded vegetable cowpea popular in Asia. How selection has contributed to the diversification of the two types of cowpea remains largely unknown. In the current stud...

Previous genetic studies in cowpea [Vigna unguiculata (L.) Walp] have shown that an active bipartite transposable element (TE) is responsible for a range of mutant phenotypes of its leaf, stem and flower. Since type II TEs have not been characterized at the molecular level in cowpea, this study was initiated to survey the presence of type II TEs in the cowpea genome. Type II TEs: Enhancer/Suppr...

In the cotton-production zone of Burkina Faso, poor soil fertility and limited access to appropriate fertilizers call for alternative approaches sustain productivity, such as introduction more legumes into agroecosystem. Legumes have nearly disappeared from local cropping systems under pressure cotton monocropping model. To develop new legume-based using a bottom-up approach, this study was bas...

Cowpea ( Vigna unguiculata (L.) Walp) is an important legume crop for food security in areas of low-input and smallholder farming throughout Africa and Asia. Genetic improvements are required to increase yield and resilience to biotic and abiotic stress and to enhance cowpea crop performance. An integrated cowpea genomic and gene expression data resource has the potential to greatly accelerate ...

Liriomyza sativae and L. trifolii are highly invasive leafminer pests of vegetable crops that have invaded southern China in recent years. Liriomyza sativae was the first of these species to invade China, but it is now being displaced by L. trifolii. The rate and extent of this displacement vary across southern China. In Hainan, monocultures of highly valuable cowpea are planted and treated ext...

The homeologous Orp1 and Orp2 regions of maize and the orthologous regions in sorghum and rice were compared by generating sequence data for >486 kb of genomic DNA. At least three genic rearrangements differentiate the maize Orp1 and Orp2 segments, including an insertion of a single gene and two deletions that removed one gene each, while no genic rearrangements were detected in the maize Orp2 ...
