Sterility mosaic disease (SMD) of pigeonpea (Cajanus cajan (L.) Millsp) first reported in 1931, is an economically most important viral disease, which is endemic to India, Nepal, Bangladesh and Myanmar. SMD was long suspected to be a viral disease, however its causal agent, pigeonpea sterility mo...

Yam (Dioscorea spp.) is an important vegetatively-propagated staple crop in West Africa. Viruses arepervasive in yam worldwide, decreasing growth and yield, as well as hindering the international move-ment of germplasm. Badnaviruses have been reported to be the most prevalent in yam, and genomeso...

Yam mosaic virus (YMV; genus Potyvirus ) is considered to cause the most economically important viral disease of yams ( Dioscorea spp.) in West Africa which is the dominant region for yam production globally. Yams are a vegetatively propagated crop and the use of virus-free planting material form...

Alleviation of poverty in developing countries continues to be the main target for scientists as well as administrators. Genetically engineered (GE) crops initially were developed to benefit large scale commercial outfits. They are currently grown on 175 million ha and more than 50% of this is co...

Maize (Zea mays L.) is a major food and fodder crop cultivated on 1.54 million ha in the Democratic Republic of the Congo (DRC). In December 2013, unusually severe chlorotic mottle symptoms and pale green streaks were observed in local varieties (Mudishi 1 and 2, Bambou, Kasayi, H614, H613, and M...

Potyviruses (genus Potyvirus; family Potyviridae) are widely distributed and represent one of the most economically important genera of plant viruses. Therefore, their accurate detection is a key factor in developing efficient control strategies. However, this can sometimes be problematic particu...

Biological control is a significant component of integrated pest management programs around the world. However, uncertainty about the risk of unanticipated effects on non-target organisms is one of the major concerns surrounding the release of biological control agents. This Brief has been prepar...

Pigeonpea sterility mosaic virus (PPSMV), a species of the genus Emaravirus, is the causal agent of sterility mosaic disease (SMD) of pigeonpea [Cajanus cajan (L.) Millsp]. This disease, dubbed the ‘green plague’, as the infected plants remain in the vegetative state without flower production, ha...
