Replication of Tomato Yellow Leaf Curl Virus in Its Whitefly Vector, Bemisia tabaci.
UNLABELLED Tomato yellow leaf curl virus (TYLCV) is a begomovirus transmitted exclusively by the whitefly Bemisia tabaci in a persistent, circulative manner. Replication of TYLCV in its vector remains controversial, and thus far, the virus has been considered to be nonpropagative. Following 8 h of acquisition on TYLCV-infected tomato plants or purified virions and then transfer to non-TYLCV-hos...
متن کاملTomato yellow leaf curl virus: No evidence for replication in the insect vector Bemisia tabaci
Begomovirus ssDNA plant virus (family Geminiviridae) replication within the Bemisia tabaci vector is controversial. Transovarial transmission, alteration to whitefly biology, or detection of viral transcripts in the vector are proposed as indirect evidence of replication of tomato yellow leaf curl virus (TYLCV). Recently, contrasting direct evidence has been reported regarding the capacity of T...
متن کاملRate of Tomato yellow leaf curl virus Translocation in the Circulative Transmission Pathway of its Vector, the Whitefly Bemisia tabaci.
ABSTRACT Whiteflies (Bemisia tabaci, biotype B) were able to transmit Tomato yellow leaf curl virus (TYLCV) 8 h after they were caged with infected tomato plants. The spread of TYLCV during this latent period was followed in organs thought to be involved in the translocation of the virus in B. tabaci. After increasing acquisition access periods (AAPs) on infected tomato plants, the stylets, the...
متن کاملTomato yellow leaf curl virus alters the host preferences of its vector Bemisia tabaci
Bemisia tabaci, the whitefly vector of Tomato yellow leaf curl virus (TYLCV), seriously reduces tomato production and quality. Here, we report the first evidence that infection by TYLCV alters the host preferences of invasive B. tabaci B (Middle East-Minor Asia 1) and Q (Mediterranean genetic group), in which TYLCV-free B. tabaci Q preferred to settle on TYLCV-infected tomato plants over health...
متن کاملEvidence for transovarial transmission of tomato yellow leaf curl virus by its vector, the whitefly Bemisia tabaci.
The whitefly Bemisia tabaci is the only vector of the tomato yellow leaf curl geminivirus (TYLCV). The insect transmits the virus in a persistent-circulative manner. TYLCV DNA was detected by polymerase chain reaction and by Southern blot hybridization in progeny (eggs, first and second instars, adults) of single viruliferous whiteflies that developed on eggplant or on cotton (two TYLCV nonhost...
