It is prerequisite to extract Ribonucleic Acid (RNA) with high quality and integrity in order to carry out molecular biology studies in any plant species. Samples collected from remote fields require preservation before being processed for RNA extraction and downstream process like RT-PCR, real t...

Root necrosis similar to those of the cassava brown streak disease (CBSD) were observed on cassava in western provinces of the Democratic Republic of Congo (DR.Congo) in the early 2000’s. However molecular laboratory diagnosis were not able to detect any causative agent responsible for the attack...

Dasheen mosaic virus (DsMV) is member of the family Potyviridae, genus Potyvirus and infects taro and other aroids wherever they grow. DsMV infection results in characteristic feathery-mottle and mosaic symptoms on leaves and can cause up to 60% production losses on taro and other edible aroids (...
