Genetic Diversity and Pathogenicity Characterization of Tomato-Infecting Begomoviruses in Taiwan.

The tomato yellow leaf curl disease (TYLCD) caused by whitefly ()-transmitted begomoviruses () has constrained tomato production in Taiwan since 1981. Lisianthus enation leaf curl virus (LELCV), tomato leaf curl Taiwan virus (ToLCTV), and tomato yellow leaf curl Thailand virus (TYLCTHV) were the major viruses associated with TYLCD. In 2019 to 2020, we investigated TYLCD throughout Taiwan, with a 10 to 100% incidence on tomato fields.

Genetic Diversity and Geographic Distribution of Cucurbit-Infecting Begomoviruses in the Philippines.

Cucurbits are important economic crops worldwide. However, the cucurbit leaf curl disease (CuLCD), caused by whitefly-transmitted begomoviruses constrains their production. In Southeast Asia, three major begomoviruses, (ToLCNDV), (SLCCNV) and (SLCuPV) are associated with CuLCD.

Genetic Diversity, Pathogenicity and Pseudorecombination of Cucurbit-Infecting Begomoviruses in Malaysia.

Cucurbits are important crops in the world. However, leaf curl disease constrains their production. Here, begomovirus diversity and pathogenicity associated with the disease in Malaysia were studied based on 49 begomovirus-detected out of 69 symptomatic plants from seven cucurbit crops in 15 locations during 2016 and 2017.
