Pest categorisation of Pulvinaria psidii

open access: yesEFSA Journal, Volume 20, Issue 8, August 2022., 2022
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Pulvinaria psidii (Hemiptera: Coccidae), the green shield scale, for the EU. P. psidii was originally described from Hawaii on Psidium sp. and it is now established in many countries in tropical and subtropical regions of the world. Within the EU, the pest has been reported from

Pest categorisation of Capsicum chlorosis virus

open access: yesEFSA Journal, Volume 20, Issue 6, June 2022., 2022
Abstract The EFSA Panel on Plant Health conducted a pest categorisation of Capsicum chlorosis virus (CaCV) for the EU territory. The identity of CaCV, a member of the genus Orthotospovirus (family Tospoviridae), is established and reliable detection and identification methods are available. The pathogen is not included in the EU Commission Implementing

Pseudomonas viridiflava: An internal outsider of the Pseudomonas syringae species complex

open access: yesMolecular Plant Pathology, Volume 23, Issue 1, Page 3-15, January 2022., 2022
Pseudomonas viridiflava is a generalist that is characterized by its phenotypic plasticity, intraspecies genetic diversity, utilization of pectate lyase, and pathogenicity island variation. Abstract Pseudomonas viridiflava is a gram‐negative pseudomonad that is phylogenetically placed within the Pseudomonas syringae species complex. P.

Pectobacterium atrosepticum KDPG aldolase, Eda, participates in the Entner–Doudoroff pathway and independently inhibits expression of virulence determinants

open access: yesMolecular Plant Pathology, Volume 22, Issue 2, Page 271-283, February 2021., 2021
A component of the Entner–Doudoroff pathway, 2‐keto‐3‐deoxy‐6‐phosphogluconate aldolase, plays a vital role in the virulence of Pectobacterium atrosepticum on potato by controlling expression of genes involved in pectin degradation. Abstract Pectobacterium carotovorum has an incomplete Entner–Doudoroff (ED) pathway, including enzyme 2‐keto‐3‐deoxy‐6 ...

A Review of Plant‐Based Therapies for the Treatment of Urinary Tract Infections in Traditional Southern African Medicine

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2021, Issue 1, 2021., 2021
Urinary tract infections (UTIs) are amongst the most common bacterial infections globally, with ∼11% of the world’s population contracting at least one infection annually. Several South African plants are used in traditional healing systems to treat UTIs, yet the therapeutic potential of these plants against bacteria that cause UTI remains poorly ...
