“…TYLCKaV was detected in tomato and tobacco; however, the infection rate was highest in eggplant indicating that it is the primary host for TYLCKaV. This result is consistent with other studies that have reported that most TYLCKaV have been isolated from eggplants in Southeast Asia (Green et al, 2003;Ha et al, 2008;Tang et al, 2014;Bagewadi and Naidu, 2016;Zhang et al, 2018). Interestingly, PepYLCIV, PepYLCAV, and AYVV were undetected in eggplant, indicating that the primary hosts for these viruses are chili pepper, tomato, and tobacco.…”

Begomoviruses, transmitted by whiteflies (Bemisia tabaci), have emerged as serious constraints to the cultivation of a wide variety of vegetable crops worldwide. Leaf samples from Solanaceae (tomato, tobacco, and eggplant) and Cucurbitaceae (cucumber and squash) plants exhibiting typical begomoviral yellowing and/or curling symptoms were collected in Northern Sumatra, Aceh province, Indonesia. Rolling circle amplification was conducted using DNA isolated from cucumber, squash, eggplant, and tobacco, and the fulllength sequences of the begomoviruses were evaluated. The following viruses were isolated: bipartite begomoviruses Tomato leaf curl New Delhi virus (ToLCNDV), Squash leaf curl China virus (SLCCNV), Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV), and a monopartite begomovirus Ageratum yellow vein virus (AYVV). Begomovirus diagnosis was conducted by PCR using begomovirus species-specific primers for Pepper yellow leaf curl Indonesia virus (PepYLCIV), Pepper yellow leaf curl Aceh virus (PepYLCAV), ToLCNDV, SLCCNV, TYLCKaV, and AYVV, which are the predominant begomoviruses. The primary begomovirus species for each plant were as follows: PepYLCAV for tomato, AYVV for tobacco, TYLCKaV for eggplant, ToLCNDV for cucumber, and SLCCNV for squash. This study provides valuable information for breeding begomovirus-resistant cultivars as horticultural crops.

“…In Africa, no begomovirus was reported on eggplant (Brown et al, 2015). Only the two begomoviruses Tomato leaf curl New Dehli virus and Tomato yellow leaf curl Kanchanaburi virus initially reported on tomato crops were also ultimately found on eggplant in Asia (Pratap et al, 2011;Zhang et al, 2018;Lukman et al, 2019). In Africa, some begomoviruses were already reported on some Solanaceae such as pepper and tomato whereas neither on eggplant (Tiendrebeogo et al, 2011;Séka et al, 2017).…”

Objective: Eggplant (Solanum melongena) is one of the important vegetables in Africa and Asia. Begomoviruses are emerging plant viruses that cause significant losses. However, there is little research on begomoviruses infecting eggplant. Therefore, this study aimed at identifying begomoviruses infecting eggplant. Methodology and results: Six samples of virus-like infected eggplants were collected in Ferkessedougou in the North of Cote d'Ivoire. The molecular tests Polymerase Chain Reaction (PCR) and Rolling Circle Amplification (RCA) were performed on the samples. One sample tested positive by PCR and RCA while the five others were negative by PCR for begomoviruses. Products from both tests were sequenced to get partial sequence of begomovirus Pepper yellow vein Mali virus (PepYVMLV) from PCR and two full genome components DNA A and DNA B of PepYVMLV from RCA. The sequences were released in Genbank. Conclusion and application of findings:This study has done the molecular characterization of the complete two genome sequence components DNA A and DNA B of Pepper yellow vein Mali on eggplant. Agro-infection of eggplants with the two components could reveal actual specific symptoms which are caused by PepYVMLV on eggplant. This could help opens possibilities of engineering resistant eggplant to PepYMLV.

“…Our previous eld survey of begomoviruses infecting solanaceous and cucurbit crops cultivated in Aceh Province in Indonesia inferred that TYLCKaV is the predominant begomovirus that infects eggplant (Kesumawati et al 2020). Given that TYLCKaV has been isolated from solanaceous crops, including eggplant in Vietnam (Ha et al 2008), Laos (Tang et al 2014), Cambodia (Bagewadi and Naidu 2016), Indonesia (Koeda et al 2016), China (Zhang et al 2018), and Myanmar (Kwak et al 2022), this virus is indicated to pose a severe constraint to eggplant production in these areas.…”

Identification of natural sources of resistance to bipartite begomovirus TYLCKaV in Solanum melongena

Yellow leaf curl disease caused by begomoviruses has emerged as a major limitation to the production of eggplant (Solanum melongena) in several regions of the world. Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV) is a bipartite begomovirus isolated from diseased eggplant in the areas of the Indochinese peninsula, South China, and Maritime Southeast Asia. In this study, ve begomovirus species isolated in Indonesia, including TYLCKaV, were inoculated to eggplant using infectious clones. Among the inoculated begomoviruses, TYLCKaV alone induced typical yellowing and curling symptoms in eggplant.Inoculation of TYLCKaV to a panel of crop species (eggplant, tomato, pepper, tobacco, cucumber, melon, and squash) commonly grown in Indonesia clari ed that TYLCKaV infects and causes yellow leaf curl disease mainly in eggplant and tomato. Agroin ltration of TYLCKaV to 736 accessions of eggplant enabled selection of 33 resistant candidates. Further evaluation by TYLCKaV graft-inoculation of the resistant candidates clari ed that 10 accessions were classi able as moderately resistant and 23 accessions as highly resistant. Among the highly resistant accessions, 22 accessions restricted viral DNA accumulation to a signi cantly lower amount than the susceptible control. These 22 highly resistant accessions represent valuable genetic resources for breeding begomovirus resistance in eggplant.
