Geminiviruses employ host DNA glycosylases to subvert DNA methylation-mediated defense

open access: yesNature Communications, 2022
Plants tightly regulate DNA methylation to regulate gene expression. Here, the authors show that the tomato yellow leaf curl China virus βC1 protein interacts with plant DNA glycosylases to promote demethylation of viral DNA and promote virulence.

Behavior of new entries and developed tomato hybrids carrying Ty-2 gene [PDF]

open access: yes, 2022
Tomato yellow leaf curl disease (TYLCD) is a serious problem hampering tomato production worldwide. In the Mediterranean Basin, disease incidence and severity are higher in the dry season increasing whitefly (Bemisia tabaci) populations. Effectiveness of

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

open access: yesAfrican 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 ...

Geminivirus C2 protein represses genes involved in sulphur assimilation and this effect can be counteracted by jasmonate treatment [PDF]

open access: yes, 2012
Geminiviruses are plant viruses that infect a broad range of crops and cause extensive losses worldwide, having an important economic impact. C2, a multifunctional pathogenicity factor encoded by geminiviruses, has been recently shown to suppress the ...

Emerging evidence of seed transmission of begomoviruses: implications in global circulation and disease outbreak

open access: yesFrontiers in Plant Science
Begomoviruses (family Geminiviridae) are known for causing devastating diseases in fruit, fibre, pulse, and vegetable crops throughout the world. Begomoviruses are transmitted in the field exclusively through insect vector whitefly (Bemisia tabaci), and ...

Identification of the determinant of tomato yellow leaf curl Kanchanaburi virus infectivity in tomato

open access: yesVirus Research, 2021
Geminiviruses cause devastating diseases in solanaceous crops, with the bipartite begomoviruses tomato yellow leaf curl Kanchanaburi virus (TYLCKaV) and pepper yellow leaf curl Thailand virus (PYLCThV) major threats in Southeast Asia. To determine the molecular mechanism of geminivirus infection, we constructed infectious clones of TYLCKaV and PYLCThV.
