Enzymatic Investigation of Zoospore Attachment to Roots of Potato Cultivars Resistant or Susceptible to Powdery Scab Disease.

For potato crops, host resistance is currently the most effective and sustainable tool to manage diseases caused by the plasmodiophorid . Arguably, zoospore root attachment is the most critical phase of infection; however, the underlying mechanisms remain unknown. This study investigated the potential role of root-surface cell-wall polysaccharides and proteins in cultivars resistant/susceptible to zoospore attachment.

Chemotaxis and Motility of Zoospores in Response to Potato Root Exudate Constituents and pH.

f. sp. is an important pathogen of potato responsible for major losses in most potato growing regions of the world.

Comparative Proteomic Analysis of Potato Roots from Resistant and Susceptible Cultivars to Zoospore Root Attachment In Vitro.

Potato ( L.) exhibits broad variations in cultivar resistance to tuber and root infections by the soilborne, obligate biotrophic pathogen . Host resistance has been recognised as an important approach in potato disease management, whereas zoospore root attachment has been identified as an effective indicator for the host resistance to root infection.

Abundance of Poleroviruses within Tasmanian Pea Crops and Surrounding Weeds, and the Genetic Diversity of TuYV Isolates Found.

The genus Polerovirus contains positive-sense, single-stranded RNA plant viruses that cause significant disease in many agricultural crops, including vegetable legumes. This study aimed to identify and determine the abundance of Polerovirus species present within Tasmanian pea crops and surrounding weeds that may act as virus reservoirs. We further sought to examine the genetic diversity of TuYV, the most commonly occurring polerovirus identified.

Multi-omics reveals mechanisms of resistance to potato root infection by Spongospora subterranea.

The pathogen Spongospora subterranea infects potato roots and developing tubers resulting in tuber yield and quality losses. Currently, there are no fully effective treatments for disease control. Host resistance is an important tool in disease management and understanding the molecular mechanisms of defence responses in roots of potato plants is required for the breeding of novel resistant cultivars.
