Summary: Drought stress is a major factor affecting agricultural production by negatively impacting plant growth and metabolism. Previous research has shown that viruses, such as the tomato yellow leaf curl virus, can enhance a plant's ability to tolerate both drought and heat stress. However, the underlying mechanisms for this induced drought tolerance need further investigation.

Summary: Seed transmission is an important factor in the epidemiology of plant pathogens, but it was found that the begomovirus tomato yellow leaf curl Sardinia virus (TYLCSV) is not seed-transmissible for tomato. Despite detecting superficial contamination of TYLCSV DNA in embryos, whole genomic molecules were not detectable, explaining the lack of seed transmissibility observed in this host.

Summary: Powdery mildew (PM) is a major disease in tomatoes, and the role of tomato yellow leaf curl Sardinia virus (TYLCSV) in response to biotic stresses is still unclear. In this study, transgenic tomatoes expressing the TYLCSV C4 protein were exposed to the causal agent of PM. The expression of TYLCSV C4 increased tolerance to PM in the transgenic tomatoes through reduced symptom occurrence, conidia adhesion, and hyphae elongation, as well as induced higher expression of pathogenesis-related genes and salicylic acid production.

Summary: A study showed that the C4 protein of tomato yellow leaf curl virus (TYLCSV) can enhance drought tolerance in tomato plants by delaying the onset of stress-related features, improving water use efficiency, and facilitating rapid post-rehydration recovery. Specific anatomical and hydraulic traits play a key role in the stress resilience associated with the C4 protein. These findings provide new insights into the mechanism through which such proteins tune the plant-virus interaction.

Summary: Tomato yellow leaf curl virus (TYLCV) is a highly harmful disease that affects tomato growth and production worldwide. Six resistance genes have been transferred to commercial tomato cultivars from wild germplasms, providing protection against TYLCV. However, only three of these resistance genes have shown significant levels of resistance. Researchers have cloned these resistance genes and studied their antiviral mechanisms, aiming to maintain and spread resistance to TYLCV globally.

Summary: Tomato yellow leaf curl viruses are causing disease outbreaks in tomato crops in tropical and subtropical regions globally. Sweet potato whitefly is the vector of this group of viruses. This research focused on the transmission biology of tomato yellow leaf curl Thailand virus (TYLCTHV) by Bemisia tabaci, revealing the virus translocation within the whitefly without replication and lack of evidence for transovarial transmission.

Summary: Research indicates a positive interaction between viruses and plants, with Tomato yellow curl virus (TYLCV) enhancing tolerance to drought in tomato plants. TYLCV-resistant tomato plants infected with the virus can survive long periods without water and produce fruits similar to control plants after recovery.

Summary: The study evaluated the efficacy of fungal F8-culture filtrate on tomato plants to combat tomato yellow leaf curl Thailand virus. Results showed that treatment with F8-culture filtrate induced strong resistance against the virus without affecting tomato growth. The study provides an effective way to induce tomato resistance against the devastating tomato yellow leaf curl disease caused by whitefly-transmitted begomoviruses.

Summary: The study constructed infectious clones of TYLCKaV and PYLCThV, revealing the TYLCKaV-B genome segment as the determinant of its infectivity in tomato. Genome-swapping and construction of chimeric clones narrowed down the region determining TYLCKaV infectivity in tomato to the intergenic region (IR) of TYLCKaV-B. These findings provide a foundation for elucidating the molecular mechanism of geminivirus infection in plants.

Summary: Resistance to Tomato Yellow Leaf Curl Virus is a major objective in tomato breeding programs. Breeders are interested in introgressing multiple resistance genes to increase resistance levels and prolong the longevity of resistant cultivars. Evaluations of commercial F1 tomato hybrids revealed that most hybrids have multiple heterozygous resistance genes. Genetic variability in traits related to tolerance, yield, and fruit quality allowed for selection of the best genotypes. The use of specific resistance genes will be valuable in breeding programs using marker-assisted selection techniques.
