Begomovirus quasispecies adapt to hosts by exploring different sequence space without changing their consensus sequences [PDF]

, 2014
Geminiviruses possess single-stranded circular DNA genomes that depend on cellular polymerases for replication in the host nucleus. In plant hosts, geminivirus populations behave as ensembles of mutant and recombinant genomes.

A novel synthetic quantification standard including virus and internal report targets : Application for the detection and quantification of emerging begomoviruses on tomato [PDF]

, 2011
Background: Begomovirus is a genus of phytopathogenic single-stranded DNA viruses, transmitted by the whitefly Bemisia tabaci. This genus includes emerging and economically significant viruses such as those associated with Tomato Yellow Leaf Curl Disease,

Cryptic species‐specific transmission of the invasive begomovirus tomato leaf curl New Delhi virus by the whitefly Bemisia tabaci

New Plant Protection, EarlyView.
ToLCNDV is typically transmitted by the whitefly Bemisia tabaci, but the efficiency of transmission varies among different cryptic species. The retention and circulation of viruses in insect vectors are crucial determinants of successful transmission to new plants.

Identification of Tomato yellow leaf curl virus-Is in The Bahamas

Plant Disease, 2000
In December 1996, symptoms of stunting, curling, and marginal chlorosis of leaves, reduced leaf size, and marked reduction in number of fruits were first seen in tomato (Lycopersicon esculentum) plants on the island of North Andros, The Bahamas. Similar symptoms were observed for the first time during fall 1997 in tomatoes on the island of Eleuthera ...

Plant defense strategies: The dual armor of disease resistance and tolerance

New Plant Protection, EarlyView.
Plants employ dual strategies against pathogens: Resistance limits invasion via immune responses, whereas tolerance mitigates damage to sustain growth—together enhancing survival under infections. Abstract Pathogen infections pose a significant threat to plant health, global food security, and ecosystems.

Fungal F8-Culture Filtrate Induces Tomato Resistance against Tomato Yellow Leaf Curl Thailand Virus

Viruses, 2021
Tomato (Solanum lycopersicum) is an important economic crop worldwide. However, tomato production is jeopardized by the devastating tomato yellow leaf curl disease caused by whitefly-transmitted begomoviruses (WTBs).

Emergence and reemergence of tomato begomoviruses in the North-East of Morocco [PDF]

, 2011
In Morocco, Tomato yellow leaf curl disease (Tylc) has emerged in 1997 [1]. Two begomovirus species causing Tylc were identified, Tomato yellow leaf curl virus (TYLCV) and Tomato yellow leaf curl Sardinia virus (TYLCSV) [2].

Tomato yellow leaf curl virus: Diagnosis and metabolites [PDF]

African Journal of Biotechnology, 2018
The existence of Tomato yellow leaf curl virus (TYLCV) was figured out in different locations in Al-Ahsaa of Saudi Arabia. Polymerase chain reaction (PCR) results of samples collected showed that TYLCV existed in all locations. Using AVcore and ACcore primers, begomoviruses family were detected in symptomatic tomato plants and by using TYv2664 and ...
