The AP2 transcription factor NtERF172 confers drought resistance by modifying NtCAT

Plant Biotechnology Journal, Volume 18, Issue 12, Page 2444-2455, December 2020., 2020
Summary Drought stress often limits plant growth and global crop yields. Catalase (CAT)‐mediated hydrogen peroxide (H2O2) scavenging plays an important role in the adaptation of plant stress responses, but the transcriptional regulation of the CAT gene in response to drought stress is not well understood.

Pest categorisation of tomato leaf curl New Delhi virus

EFSA Journal, Volume 18, Issue 7, July 2020., 2020
Abstract Following a request from the European Commission, the Panel on Plant Health performed a pest categorisation on tomato leaf curl New Delhi virus (ToLCNDV). ToLCNDV is a well‐defined bipartite Begomovirus species, sometimes associated with satellite molecules. It is transmitted by Bemisia tabaci to a wide range of hosts. ToLCNDV is reported from

Molecular diversity of Cotton leaf curl Gezira virus isolates and their satellite DNAs associated with okra leaf curl disease in Burkina Faso

Virology Journal, 2010
Okra leaf curl disease (OLCD) is a major constraint on okra (Abelmoschus esculentus) production and is widespread in Africa. Using a large number of samples representative of the major growing regions in Burkina Faso (BF), we show that the disease is ...

Aphid transmission of nanoviruses

Archives of Insect Biochemistry and Physiology, Volume 104, Issue 2, June 2020., 2020
Schematic diagram showing the translocation routes of circulative nonpropagative plant viruses within aphid vectors (not to scale). Abstract The genus Nanovirus consists of plant viruses that predominantly infect legumes leading to devastating crop losses. Nanoviruses are transmitted by various aphid species.
