Effect of calcium soil amendments on phenolic compounds and soft rot resistance in potato tubers

Ngadze, Elizabeth; Coutinho, Teresa A.; Icishahayo, David; Van der Waals, Jacqueline Elise (Elsevier, 2014-08)

Nutrients such as boron, nitrogen and calcium stimulate the production of phenols. This research focuses on the role of calcium in increasing phenol metabolism in potato peels and the ensuing tuber resistance to soft rot ...
First Report of soft rot of potatoes caused by Dickeya dadantii in Zimbabwe

Ngadze, Elizabeth; Coutinho, Teresa A.; Van der Waals, Jacqueline Elise (American Phytopathological Society, 2010-10)

A survey was carried out in the potato- (Solarium tuberosum L.) growing regions of Zimbabwe in April 2009 to assess the prevalence of bacterial soft rot. A total of 125 tubers with soft rot symptoms were collected. The ...
Pectinolytic bacteria associated with potato soft rot and blackleg in South Africa and Zimbabwe

Ngadze, Elizabeth; Brady, Carrie Louise; Coutinho, Teresa A.; Van der Waals, Jacqueline Elise (Springer, 2012)

Soft rot and blackleg can cause severe economic losses in potato production in South Africa and Zimbabwe depending on climatic conditions. The aim of the study was to identify the predominant bacteria causing potato ...
The role of polyphenol oxidase, peroxidase, phenylalanine ammonia lyase, chlorogenic acid and total soluble phenols in the resistance of potatoes to soft rot

Ngadze, Elizabeth; Icishahayo, David; Coutinho, Teresa A.; Van der Waals, Jacqueline Elise (American Phytopathological Society, 2012)

Pectobacterium atrosepticum (Pa), P. carotovorum subsp. brasiliensis (Pcb) and Dickeya spp. cause soft rot of potato worldwide. Plants respond to bacterial invasion by activating defense responses associated with ...
