Messal, Mandy; Slippers, Bernard; Naidoo, Sanushka; Bezuidt, Keoagile Ignatius Oliver; Kemler, Martin (MDPI, 2019-10)Fungi represent a common and diverse part of the microbial communities that associate with plants. They also commonly colonise various plant parts asymptomatically. The molecular mechanisms of these interactions are, ...

McTaggart, Alistair R.; Duong, Tuan A.; Le, Vang Quy; Shuey, Louise S.; Smidt, Werner; Naidoo, Sanushka; Wingfield, Michael J.; Wingfield, Brenda D. (Future Medicine, 2018-11)It is challenging to sequence and assemble genomes of obligate plant pathogens and microorganisms because of limited amounts of DNA, comparatively large genomes and high numbers of repeat regions. We sequenced the 1.2 ...

Visser, Erik A.; Wegrzyn, Jill L.; Steenkamp, Emma Theodora; Myburg, Alexander Andrew; Naidoo, Sanushka (MDPI, 2019-09-04)Fusarium circinatum poses a serious threat to many pine species in both commercial and natural pine forests. Knowledge regarding the molecular basis of pine-F. circinatum host-pathogen interactions could assist efforts to ...

Meyer, Febe E.; Shuey, Louise S.; Naidoo, Sitha; Mamni, Thandekile B.; Berger, David Kenneth; Myburg, Alexander Andrew; Van den Berg, Noelani; Naidoo, Sanushka (Frontiers Research Foundation, 2016-03-02)Damage caused by Phytophthora cinnamomi Rands remains an important concern on forest tree species. The pathogen causes root and collar rot, stem cankers, and dieback of various economically important Eucalyptus spp. In ...

Du Toit, Yves; Coles, Donovin William; Mewalal, Ritesh; Christie, Nanette; Naidoo, Sanushka (Frontiers Media, 2020-02-17)Many pests and pathogens threaten Eucalyptus plantations. The study of defense responses in this economically important wood and fiber crop enables the discovery of novel pathways and genes, which may be adopted to improve ...

Backer, Robert; Naidoo, Sanushka; Van den Berg, Noelani (BMC, 2023-11-08)A plant’s defense against pathogens involves an extensive set of phytohormone regulated defense signaling pathways. The salicylic acid (SA)-signaling pathway is one of the most well-studied in plant defense. The bulk of ...

Lall, Namrita; Kishore, Navneet; Momtaz, Saeideh; Hussein, Ahmed A.; Naidoo, Sanushka; Nqephe, Mabatho; Crampton, Bridget Genevieve (Wiley, 2015-11)Skin hyper-pigmentation is a condition initiated by the overproduction of melanin existing in the melanocytes. Melanin pigment is responsible for the colour of skin in humans. It is formed through a series of oxidative ...

Visser, Erik A.; Mangwanda, Ronishree; Becker, John V.W.; Külheim, C.; Foley, William; Myburg, Alexander Andrew; Naidoo, Sanushka (Wiley, 2015-12)Induction of systemic defences to fungal pathogens is well described in model plant systems, but not extensively studied in large woody perennials. Systemic induced defences in long-lived tree species, such as Eucalyptus ...
