Vector acquisition and co-inoculation of two plant viruses influences transmission, infection, and replication in new hosts.

This study investigated the role of vector acquisition and transmission on the propagation of single and co-infections of tomato yellow leaf curl virus (TYLCV,) and tomato mottle virus (ToMoV) (Family: Geminiviridae, Genus: Begomovirus) by the whitefly vector Bemisia tabaci MEAM1 (Gennadius) in tomato. The aim of this research was to determine if the manner in which viruses are co-acquired and co-transmitted changes the probability of acquisition, transmission and new host infections. Whiteflies acquired virus by feeding on singly infected plants, co-infected plants, or by sequential feeding on singly infected plants.

First Report of Tomato Yellow Leaf Curl Virus Infecting Upland Cotton (Gossypium hirsutum) in Alabama, USA.

Cotton (Gossypium hirsutum L.) is used as a non-host of tomato yellow leaf curl virus (TYLCV) (family Geminiviridae, genus Begomovirus) in many studies (Ghanim and Czosnek 2000; Legarrea et al. 2015; Zeidan and Czosnek 1991), but only one reports methods used to determine host-status (Sinisterra et al.
