Summary: In this study, the pathogenicity of two different strains of Tomato leaf curl New Delhi virus (ToLCNDV) in tomato plants was examined. It was found that the DNA-A segment of ToLCNDV is the main factor determining its infectivity, and the coat protein (CP) is essential for its pathogenicity in tomatoes. Furthermore, interactions between the CPs and a tomato gene were discovered through a yeast two-hybrid screen.

Summary: Understanding the seedborne nature of plant viruses is crucial for disease control strategies and seed market. This study revealed that ToLCNDV, ToLCTV, and TYLCTHV can be transmitted through seeds or pollens of cucumber and tomato plants.

Summary: TYLCV-IS76, a recombinant between TYLCV and TYLCSV, has replaced its parental viruses in southern Morocco. In laboratory conditions, TYLCV-IS76 accumulated significantly more than its parental viruses and displaced LSRec, another recombinant. However, TYLCV-IS76 did not show vector transmission advantage over LSRec and TYLCV. The recombination event that generated TYLCV-IS76 seems to induce competitive advantage only in the plant compartment.

Summary: Viruses undergo population bottlenecks in host cells, affecting the number of viral genomes and promoting evolutionary selection. This study shows that tomato yellow leaf curl virus (TYLCV) also experiences bottlenecking in host plant cells, which may serve as a mechanism for the timely selection of beneficial mutations.

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: The incidence and severity of begomovirus diseases have been increasing globally, and ridge gourd is the latest crop to be highly susceptible to the outbreak of tomato leaf curl New Delhi virus (ToLCNDV) in India. This study successfully produced polyclonal antibodies (ToLCNDV-Rg-CP-PAb) using the coat protein (CP) gene from a ToLCNDV-Rg isolate, which could detect the virus in symptomatic ridge gourd leaf samples through multiple assays. The antibodies also detected other commonly occurring begomoviruses in South India, providing a tool for monitoring disease outbreaks in multiple crops.

Summary: Potato apical leaf curl disease, caused by a global threat bipartite virus known as tomato leaf curl New Delhi virus (ToLCNDV), has rapidly spread in India with no known antiviral products or resistant cultivars yet. The disease can only be managed through planting healthy seed potatoes, but this measure may not be sustainable in meeting the increasing food demand of the population. Efforts to develop resistant varieties through conventional breeding or advanced techniques like genome editing may provide a potential solution in the future.

Summary: Tomato leaf curl New Delhi virus (ToLCNDV) is a newly emerging begomovirus that causes serious production losses in cucurbits. Grafting is a faster and more flexible solution compared to genetic resistance, as it induces tolerance against airborne virus infection. Through screening, potential rootstocks have been identified to achieve suitable levels of tolerance against the virus in commercial cucurbit varieties.

Summary: During the year 2020-2021, a disease syndrome commonly observed in railway creepers in Gorakhpur Province, India was studied. Whitefly was identified as the vector for the transmission of the disease. PCR analysis and sequence matching revealed that the disease was caused by a recombinant strain of ToLCNDV, with a high similarity to ToLCNDV from snake gourd.

Summary: This study found that the Tomato leaf curl New Delhi virus (ToLCNDV) was seedborne in melon plants, with the virus detectable in the floral parts and mature seeds. The virus could be reduced on the seed coat by chemical disinfection, but low levels of the virus were still present in the internal portion of the seed. However, grow-out studies showed that ToLCNDV was not transmitted from seeds to offspring.

Summary: The molecular characterization of a tomato leaf curl New Delhi virus isolate associated with severe and recurrent outbreaks in protected crops of zucchini squash in southern Italy is reported. The fully sequenced genome consists of two genomic components, DNA-A and DNA-B, and phylogenetic analysis showed its clustering with western Mediterranean Basin isolates. A recombinant isolate in the AC1-AC4 region, involving a putative minor parent from Pakistan and putative major parent from Bangladesh, was detected. This is the first report of a ToLCNDV-ES recombinant isolate in Italy.

Summary: Tomato leaf curl New Delhi virus (ToLCNDV) has caused significant damage to Cucurbitaceae cultivation in Europe from 2017 to 2020. This study identified a new isolate of ToLCNDV in Pakistan and analyzed its infectivity in different cucurbit crops. The results showed severe infection in most cucurbit crops, indicating the potential resistance of watermelon cultivars to ToLCNDV. These findings provide valuable information for breeding resistance to ToLCNDV in Southeast Asia and the Mediterranean region.
