Zucchini yellow mosaic virus (ZYMV; potyviridae) represents a major pathogen of Cucurbitaceae crops. ZYMV resistance in melon PI 414723 is conditioned by dominant allele at the Zym locus. This resistant accession restricts viral spread and does not develop symptoms, but necrosis sometimes develops response to inoculation. In previous studies, has been mapped linkage group II genetic map. presen...

Cassava is an important staple food in Africa and a major source of carbohydrates for 800 million people globally. However, cassava suffers severe yield losses caused by many factors including pests diseases. A devastating disease brown streak (CBSD) the ipomoviruses (CBSIs) (family Potyviridae ), virus (CBSV), Ugandan (UCBSV). Spread CBSD mainly through planting infected stem cuttings used pro...

bean yellow mosaic virus (bymv, potyvirus, potyviridae) causes serious disease in gladiolus spp. in this work, the possibility of obtaining bymv free plant material from virus infected gladiolus corms was studied. thermotherapy, meristem-tip culture and combination of both techniques on infected corms/meristem-tip explants (0.5–1 mm in length) resulted in bymv elimination up to 15.38, 78.04 and...
