Potato yellow dwarf virus
Encyclopedia
Potato yellow dwarf virus (PYDV) is a plant
virus
of order Mononegavirales
, family Rhabdoviridae
and genus Nucleorhabdovirus. The virus was first identified in 1922 in the USA by Barrus and Chupp (1922) who reported it having an effect on the plant species Solanum tuberosum. The virus
is characterised for its various effects on the potato
including stunted growth, dwarfing and apical yellowing. The virus
also effects the tuber as it causes cracking and malformation. The virus is transmitted by the insect vector Agallia constricta. The insect becomes infected upon feeding on an infected plant and then plays host for the virus infecting every plant it feed upon after this event.
