N Protein of Tomato Spotted Wilt Virus Proven to Be Antagonistic Against Tomato Yellow Leaf Curl Virus in Nicotiana benthamiana. [PDF]

Mol Plant Pathol
N protein of tomato spotted wilt virus reduces the expression of the key protein V1 of tomato yellow leaf curl virus in co‐transfected Nicotiana benthamiana, through affecting host energy metabolism‐related pathways. ABSTRACT Two phylogenetically unrelated viruses transmitted by different insect vectors, tomato spotted wilt virus (TSWV) and tomato ...

Varietal Response to Groundnut Rosette Disease and the First Report of Groundnut ringspot virus in Ghana [PDF]

Plant Disease, 2016
Twelve cultivars of groundnut were screened in field trials for resistance to groundnut rosette disease (GRD), caused by coinfection with Groundnut rosette assistor virus (GRAV), Groundnut rosette virus (GRV), and its satellite RNA in the coastal savannah of Ghana.

Commodity risk assessment of <i>Petunia</i> spp. and <i>Calibrachoa</i> spp. unrooted cuttings from Kenya. [PDF]

EFSA J
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Kenya. The relevance of any pest for

Intended and unintended consequences of genetically modified crops – myth, fact and/or manageable outcomes?

New Zealand Journal of Agricultural Research, Volume 66, Issue 6, Page 519-619, December 2023., 2023
ABSTRACT Food and feed has been produced from genetically modified (GM) crops for 25 years. It is timely to review whether this technology has globally delivered the expected benefits and whether the ongoing debate on risks is justified. Expected benefits associated with GM include increased crop yields, reduced pesticide and insecticide use, reduced ...

Tolerance of plant virus disease: Its genetic, physiological, and epidemiological significance

Food and Energy Security, Volume 12, Issue 6, November 2023., 2023
Plant viruses lead to biotic stress in plants, affecting growth, reproductive fitness and yield. Tolerance of viruses and virus disease may provide a host defence mechanism against deleterious effects, but further physiological and epidemiological studies are required to determine the circumstances in which it can be effectively used for crop ...

The role of ornamental plants as hosts of Tomato chlorotic spot virus and its vector thrips affecting tomato production

Entomologia Experimentalis et Applicata, Volume 171, Issue 5, Page 395-405, May 2023., 2023
Tomato chlorotic spot virus (TCSV), vectored by thrips, is an important disease of tomato in South Florida, USA. We investigated the presence of thrips and TCSV in 24 ornamental plant species. Thrips, mainly Frankliniella occidentalis and Frankliniella schultzei (Thysanoptera: Thripidae), were found in high abundance in ornamental flowering plants in a
