Upcoming webinars
The molecular dialogue between Eucalyptus grandis and the myrtle rust pathogen
Presenter: Shae Swanepoel, PhD candidate at the University of Pretoria, South Africa
Date and time: 13 November, 7:00pm NZST
Eucalyptus grandis is among the most important agricultural forestry species grown worldwide for their value in the paper, pulp and timber industries. As a myrtle, E. grandis is known to be susceptible to Austropuccinia psidii, the pathogen that causes myrtle rust. Little is known about the molecular dialogue that exists between this host and pathogen and understanding this complex interplay will facilitate the development of robust disease management strategies. In this webinar, Shae Swanepoel (PhD candidate at the University of Pretoria) will share the results of a study that investigated these molecular interactions in resistant and susceptible E. grandis and the pandemic biotype of A. psidii using a dual RNA-seq approach.
Seedlings from Australia were screened, and leaf samples were collected at 12 hours, 1, 2 and 5 days post inoculation (hpi/dpi). RNA-seq was performed at a read depth of 40 million that enabled dual mapping to the E. grandis and A. psidii reference genomes. Resistant seedlings showed up-regulation of genes involved in brassinosteroid signalling at 2-dpi, and genes associated with this pathway underlie two previously identified disease resistance loci. Numerous disease resistance genes were identified within these loci, showing extensive transcriptional reprogramming in the presence of the pathogen. A. psidii expressed a total of 890 genes during the interactions with E. grandis, and a rust transferred protein was identified as uniquely expressed in susceptible hosts at 5-dpi. These findings offer targets for improved disease control strategies against this devastating pathogen.
