The entomopathogenic fungus Metarhizium anisopliae MA05-169 is a transformant strain that has been metabolically engineered to express dihydroxynaphthalene-melanin biosynthesis genes. In contrast to the wild type strain, the transformant displays a greater resistance to environmental stress and a higher virulence toward target insect host. However, the underlying mechanisms for these characteri...

Abstract Cowpea ( Vigna unguiculata ) is one of the most important crops in semiarid areas world, where it thrives hot, dry conditions. While cowpea able to withstand abiotic stresses, suffers serious losses from biotic antagonists, including infestation by aphid Aphis craccivora ). infestations are highly destructive, especially on young plants. However, unclear whether damage result aphids ha...
