TYLCV is also challenging outside the United States. Results showed that mechanisms involving sugar-signaling (i.e., LIN6/HT1), water channels (i.e., TIP1;1), hormone homeostasis (i.e., ABA and SA) and urea accumulation were shared by S. habrochaites and R plants, but not by S. habrochaites and S tomatoes.

Because cultivated tomato is inherently susceptible to these viruses, breeders have incorporated several resistance alleles from wild tomato relatives. Two levels of resistance are defined. Not a very innovative name, the tomato yellow leaf curl virus (TYLCV) was identified in 2007 and there was an extensive program put out to educate farmers as its occurrence was common in greenhouses and not open gardens. There may be several spots on affected fruit and they may join up and cover the whole fruit. “However, the recent mild winters have been extremely conducive for the virus and haven’t been able to break the disease cycle.”, In addition to weather circumstances, Johnson notices that the virus is most destructive in regions with overlapping production windows.
