Dear Editor, Tomato yellow leaf curl virus (TYLCV) is a whitefly-transmitted geminivirus infecting tomato crops (Czosnek, 2007). TYLCV-resistant (R) and susceptible (S) lines with the same genetic background have been bred using Solanum habrochaites as the resistance source. The gene(s) conferring resistance are unknown. Previously, we demonstrated that the hexose transporter gene LeHT1 is up-r...

Bemisia tabaci (Gennadius) is one of the economically most damaging insects to crops in tropical and subtropical regions. Severe damage is caused by feeding and more seriously by transmitting viruses. Those of the genus begomovirus (Geminiviridae) cause the most significant crop diseases and are transmitted by B. tabaci in a persistent circulative mode, a process which is largely unknown. To an...
