Main conclusion A gene-to-metabolite approach afforded new insights regarding defence mechanisms in oat plants that can be incorporated into plant breeding programmes for the selection of markers and genes related to disease resistance. Abstract Monitoring metabolite levels and changes therein can complement and corroborate transcriptome (mRNA) data on plant–pathogen interactions, thus revealing mechanisms involved in pathogen...
Pathogenicity of Puccinia porri on Allium in South AfricaNARA Subscribed
Allium crops are commonly grown in South Africa and harvested as either fresh produce for the domestic and export markets or as seed. Apart from occasional outbreaks on garlic, rust is problematic as a cosmetic disease with unappealing uredinia regularly observed on freshly packed produce of bunching onion and leek in supermarkets. Spore morphology and phylogenetic analysis of five rust samples collected from A. fistulosum (bu...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
