The Global Dimension of Tomato Yellow Leaf Curl Disease: Current Status and Breeding Perspectives

Tomato yellow leaf curl disease (TYLCD) caused by tomato yellow leaf curl virus (TYLCV) and a group of related begomoviruses is an important disease which in recent years has caused serious economic problems in tomato (Solanum lycopersicum) production worldwide. Spreading of the vectors, whiteflies of the Bemisia tabaci complex, has been responsible for many TYLCD outbreaks. In this review, we summarize the current knowledge of TYLCV and TYLV-like begomoviruses and the driving forces of the increasing global significance through rapid evolution of begomovirus variants, mixed infection in the field, association with betasatellites and host range expansion. Breeding for host plant resistance is considered as one of the most promising and sustainable methods in controlling TYLCD. Resistance to TYLCD was found in several wild relatives of tomato from which six TYLCV resistance genes (Ty-1 to Ty-6) have been identified. Currently, Ty-1 and Ty-3 are the primary resistance genes widely used in tomato breeding programs. Ty-2 is also exploited commercially either alone or in combination with other Ty-genes (i.e., Ty-1, Ty-3 or ty-5). Additionally, screening of a large collection of wild tomato species has resulted in the identification of novel TYLCD resistance sources. In this review, we focus on genetic resources used to date in breeding for TYLCVD resistance. For future breeding strategies, we discuss several leads in order to make full use of the naturally occurring and engineered resistance to mount a broad-spectrum and sustainable begomovirus resistance.

“…Domesticated tomato is known to be vulnerable to TYLCV infection, but resistance exists in wild tomato species ( Ji et al, 2007b ). Accessions exhibiting no TYLCD symptoms upon infection have been reported in a number of species, including S. arcanum , S. cheesmaniae , S. chilense, S. chmielewskii , S. corneliomulleri , S. galapagense , S. habrochaites , S. neorickii , S. pennellii , S. peruvianum , and S. pimpinellifolium ( Ji et al, 2007b ; Vidavski et al, 2008 ; De la Peña et al, 2010 ; Pereira-Carvalho et al, 2010 ; Tomás et al, 2011 ). So far, three TYLCV resistance genes have been cloned.…”

Resistance to Tomato Yellow Leaf Curl Virus in Tomato Germplasm

Tomato yellow leaf curl virus (TYLCV) is a virus species causing epidemics in tomato (Solanum lycopersicum) worldwide. Many efforts have been focused on identification of resistance sources by screening wild tomato species. In many cases, the accession numbers were either not provided in publications or not provided in a consistent manner, which led to redundant screenings. In the current study, we summarized efforts on the screenings of wild tomato species for TYLCV resistance from various publications. In addition, we screened 708 accessions from 13 wild tomato species using different inoculation assays (i.e., whitefly natural infection and Agrobacterium-mediated inoculation) from which 138 accessions exhibited no tomato yellow leaf curl disease (TYLCD) symptoms. These symptomless accessions include 14 accessions from S. arcanum, 43 from S. chilense, 1 from S. chmielewskii, 28 from S. corneliomulleri, 5 from S. habrochaites, 4 from S. huaylasense, 2 from S. neorickii, 1 from S. pennellii, 39 from S. peruvianum, and 1 from S. pimpinellifolium. Most of the screened S. chilense accessions remained symptomless. Many symptomless accessions were also identified in S. arcanum, S. corneliomulleri, and S. peruvianum. A large number of S. pimpinellifolium accessions were screened. However, almost all of the tested accessions showed TYLCD symptoms. Further, we studied allelic variation of the Ty-1/Ty-3 gene in few S. chilense accessions by applying virus-induced gene silencing and allele mining, leading to identification of a number of allele-specific polymorphisms. Taken together, we present a comprehensive overview on TYLCV resistance and susceptibility in wild tomato germplasm, and demonstrate how to study allelic variants of the cloned Ty-genes in TYLCV-resistant accessions.

“…Indiscriminate pesticide use leads to insect resistance and loss of natural enemies (Schuster and Polston 1999;Salati et al 2002). Resistance genes against TYLCVD have been identified in wild tomato accessions and have been successfully introgressed into cultivated tomato (reviewed by de la Pen˜a et al 2010). The chromosome locations of several resistance genes have been determined, and molecular markers linked to three major resistance genes (Ty-1, Ty-2 and Ty-3) are extensively used for marker-assisted selection in breeding programs worldwide.…”

Transgenic tomato plants expressing full‐length (CPV1) and truncated coat protein (CP) gene (CPV2) of Tomato leaf curl Taiwan virus (ToLCTWV) were generated by Agrobacterium‐mediated transformation. Transgene integration and expression was confirmed by PCR and Southern blotting and Northern analysis, respectively. Resistance was evaluated both in plants of T0 and T1 progenies using viruliferous whiteflies under two different inoculum pressures (10–15 and 40–50 whiteflies/plant). Upon inoculation with ToLCTWV using viruliferous whiteflies, various levels of phenotypic reaction were observed. No complete resistance was observed in any of the plants tested. The reaction of the transgenic tomato lines carrying full‐length and truncated CP gene to ToLCTWV phenotype was (i) susceptible as non‐transgenic control, (ii) delayed symptom expression, (iii) complete susceptible (from delayed symptom expression phenotype) and (iv) recovered phenotype (either plants from symptom expression as non‐transgenic plants or delayed symptom expression phenotype). Dot blot quantification of the ToLCTWV using the replicase gene as a probe revealed that the recovered phenotypes accumulated a low level of ToLCTWV, and virus concentration was gradually reduced from 10 to 14 weeks postinoculation. The possible mechanisms of CP‐mediated resistance are discussed.
