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: The transmission capacity of TYLCV-viruliferous B. tabaci in tomato fields was studied. Results showed that carrying the virus or acquiring the virus during the trial did not influence whitefly dispersal compared to non-viruliferous B. tabaci. Viruliferous and non-viruliferous whiteflies were most abundant on the central plant, and the mortality rate was higher in viruliferous whiteflies. The study suggests that the virus itself does not seem to affect whitefly dispersal.

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: Transmission parameters of ToLCNDV-ES differ between zucchini and tomato plants, with significantly higher transmission efficiency in zucchini. This may explain the different incidences of ToLCNDV-ES in zucchini and tomato crops in Spain. The results are also important for virus management and the trade and transport of infected plant material.

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: 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: By experimentally profiling translation initiation sites, we have identified unannotated genes in tomato yellow leaf curl Thailand virus (TYLCTHV) and determined their association with transcriptional and/or translational start sites and flanking mRNA sequences. We have also discovered the importance of an unexplored gene, BV2, for pathogenicity. This study highlights the significance of coding complexity in plant viruses.

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: Begomoviruses, highly pathogenic plant viruses, are economically important and contribute significantly to global crop diseases. This study investigated the molecular mechanisms underlying the interactions between begomoviruses and their whitefly vector (Bemisia tabaci). The researchers found that a specific whitefly species efficiently transmitted the virus, while another species did not. They identified a protein in the whitefly that interacts with the virus and found that viral infection suppressed the transcription of an innate immunity-related gene in the whitefly, which enhanced virus accumulation. The study provides insights into the complex interactions between begomoviruses and their vector and highlights the importance of innate immunity in virus transmission.

Summary: The study showed that mixed infections of ToCV+TYLCV induced synergistic disease effects in tomato plants, resulting in severe disease symptoms and reduced plant growth. Virus accumulation in mixed infected plants was higher than in singly infected plants, but transmission by whiteflies was not affected.

Summary: The Xylella genus contains plant pathogens that are major threats to agriculture in America and Europe. Extensive research has been conducted on different subspecies of Xylella fastidiosa (Xf), but comparative analysis at above-species levels was lacking due to the unavailability of appropriate data sets. A new Xylella species causing pear leaf scorch in Taiwan was recently described, and the complete genome sequence of this species was reported in this study. The study contributed to understanding the phylogeny, genomic divergence, and gene content of various Xylella representatives.

Summary: AVPU1426, an inbred line developed at World Vegetable Center from a Bangladeshi landrace, showed resistance to Squash Leaf Curl China Virus and Tomato Leaf Curl New Delhi Virus in field tests. This resistance was found to be conferred by a single recessive gene and the fruit yield and quality of AVPU1426 were comparable to a recently released commercial F1 hybrid.

Summary: This study examines the direct and indirect effects of two prevalent begomoviruses, Tomato yellow leaf curl Thailand virus (TYLCTHV) and Tomato leaf curl Taiwan virus (ToLCTV), on the sweet potato whitefly (Bemisia tabaci). The results show that TYLCTHV has no effects on the whitefly, while ToLCTV negatively affects its fecundity and nymph developmental time, and alters its feeding preference. The different effects of virus infection may contribute to the lower prevalence of ToLCTV compared to TYLCTHV in fields in Taiwan.

Summary: Viral diseases pose significant constraints to tomato, cucumber, and mung bean production in Tajikistan. Cucumber mosaic virus (CMV) and viruses from the Potyvirus genus were found to be highly prevalent. These viruses, commonly transmitted by aphids, necessitate effective aphid management for sustainable production of these crops in Tajikistan.
