“…However, CuLCD caused by whitefly ( Bemisia tabaci )-transmitted begomoviruses constrains cucurbit production and has resulted in significant yield losses up to 100% [ 9 , 10 , 11 ]. ToLCNDV, SLCCNV and SLCuPV are the predominant cucurbit-infecting begomoviruses in Southeast Asia [ 8 , 11 , 15 , 16 , 17 , 18 , 19 , 21 , 22 , 23 , 24 , 29 , 30 , 31 , 35 , 38 , 39 ]. Since CuLCD emerged in the Philippines as early as 1977 [ 20 ], SLCuPV and SLCCNV were identified in Luzon in 2003 and 2006, respectively [ 21 , 22 ].…”

“…Since CuLCD emerged in the Philippines as early as 1977 [ 20 ], SLCuPV and SLCCNV were identified in Luzon in 2003 and 2006, respectively [ 21 , 22 ]. SLCuPV was also identified in Taiwan in 2001 and then became an important cucurbit-infecting begomovirus [ 15 , 38 , 39 ]. Based on the samples collected during 2018–2019, SLCuPV and SLCCNV were confirmed as causes of CuLCD throughout the Philippines.…”

“…Furthermore, SLCCNV sequences were also obtained from wax gourd (MK064240) in Cambodia and pumpkin (KC857509) in Vietnam [ 24 ]. The squash disease associated virus, SLCuPV, was identified from diseased squash collected in 2001 and has become the predominant cucurbit-infecting begomovirus in Taiwan [ 15 , 38 , 39 ]. Afterwards, SLCuPV was reported in 2003 in the Philippines [ 21 ].…”

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, Tomato leaf curl New Delhi virus (ToLCNDV), Squash leaf curl China virus (SLCCNV) and Squash leaf curl Philippines virus (SLCuPV) are associated with CuLCD. SLCuPV and SLCCNV were identified in Luzon, the Philippines. Here, the genetic diversity and geographic distribution of CuLCD-associated begomoviruses in the Philippines were studied based on 103 begomovirus detected out of 249 cucurbit samples collected from 60 locations throughout the country in 2018 and 2019. The presence of SLCCNV and SLCuPV throughout the Philippines were confirmed by begomovirus PCR detection and viral DNA sequence analysis. SLCuPV was determined as a predominant CuLCD-associated begomovirus and grouped into two strains. Interestingly, SLCCNV was detected in pumpkin and bottle gourd without associated viral DNA-B and mixed-infected with SLCuPV. Furthermore, the pathogenicity of selected isolates of SLCCNV and SLCuPV was confirmed. The results provide virus genetic diversity associated with CuLCD for further disease management, especially in developing the disease-resistant cultivars in the Philippines as well as Southeast Asia.
