Tomato yellow leaf curl geminivirus
(TYLCV) is a whitefly-transmitted geminivirus
that causes serious economic
losses to tomato crops all over the world
(26). Outbreaks of diseases caused by
TYLCV and other closely related geminiviruses
are being reported in new areas
(6,9,18) and affecting new crops (30). In
Spain, TYLCV has mainly affected tomato
crops, but recently it has also been detected
in bean fields (22) and infecting new weed
hosts (3).
