(University of Pretoria, 2013)Pectobacterium carotovorum subsp. brasiliense (Pcb) is a plant pathogenic bacterium that causes blackleg and tuber soft rot disease of potato worldwide. Pectobacterium spp. are characterized by the secretion of large ...
-
(University of Pretoria, 2014)Pantoea ananatis is an important plant pathogen that causes disease symptoms in different plants worldwide. However, most of the virulence determinants of this pathogen have not been identified and functionally characterized. ...

Diversity of fumonisin-producing Aspergillus and Fusarium species in maize collected in South Africa (University of Pretoria, 2022)Maize(Zea mays L.) is a major crop grown all over the world, and it is a staple in the diets of millions of people, particularly in Africa. Fusarium and Aspergillus fungal species are reported to be associated with maize ...
-
(University of Pretoria, 2020)The trans-encoded small RNAs (sRNAs) are novel gene expression regulators in bacteria. In response to external stimuli, sRNAs rapidly modulate the expression of genes at the post-transcriptional level to allow bacteria to ...
-
(University of Pretoria, 2022)Phytophthora parasitica is one of the most destructive oomycetes. During its infection process, P. parasitica secretes hundreds of RxLR effector proteins (including the conserved RxLR effectors (CRE)) into the cytoplasmic ...
-
(University of Pretoria, 2022)The growing world population together with impacts of climate change place ever-greater demands on the world food supply. On the other hand, food security is threatened by various biotic threats, including filamentous ...
-
(University of Pretoria, 2020)Pectobacterium carotovorum subsp. brasiliense 1692 is an economically important pathogen as it causes soft rot and blackleg of numerous agricultural crops, especially potato, in South Africa and in other parts of the ...
-
(University of Pretoria, 2020)Two component systems (TCSs) are one of the predominant methods for bacteria to detect and respond to environmental change. A typical TCS consists of a histidine kinase (HK), responsible for sensing inter- and intracellular ...
-
(University of Pretoria, 2013)Meloiodgyne incognita, one of the most aggressive plant parasitic nematodes species on potato in South Africa, belongs to a group of plant parasitic nematodes commonly known as root knot nematodes (RKN). This group of ...
-
(University of Pretoria, 2012)Potato (Solanum tuberosum) is regarded as one of the single most important vegetable crops in South Africa, with an average annual production of 2 million metric tons. The potato industry contributes to an average of $ ...
-
(University of Pretoria, 2021)Under field conditions, drought and heat stress are more prevalent in combination than as isolated phenomena. Studies that were aimed at characterizing the consequences of both heat and drought stresses on plants reported ...
-
(University of Pretoria, 2022)Outer membrane vesicles (OMVs) are spherical nanoparticles formed from bulging and the subsequent fission of the outer membrane of Gram-negative bacteria. OMVs play a role in the secretion and transport of molecules in ...
-
(University of Pretoria, 2022-10-09)SUMMARY Soft Rot Pectobacteriaceae (SRP) is a family of Gram-negative bacteria (GNB) that causes damage to crop and ornamental plants. Pectobacterium brasiliense 1692 (Pbr1692) is among the most devastating Pectobacterium ...
-
(University of Pretoria, 2016)Pectobacterium carotovorum subsp. brasiliense, a necrotrophic phytopathogen belonging to the soft rot Enterobacteriaceae (SRE) family is responsible for causing tuber soft rot and blackleg diseases of stems in potato plants. ...
-
(University of Pretoria, 2020)Several members of the soft rot Pectobacteriaceae family such as Pectobacterium brasiliense 1692 (Pb1692) attack a wide range of crops worldwide. P. brasiliense is a major cause of black leg and soft rot disease in several ...
