Abstract:
... Seed-vectored endophytes internally colonize plant seeds and remain without eliciting disease symptoms. Microbes are carried by seeds generation after generation to benefit the host during and following seed germination. Seed-vectored endophytes have been poorly investigated and research targeted at understanding their biology will have immense applications in agriculture and horticulture. Some re ...

Abstract:
... The development of canola cultivars with resistance to soil-borne diseases, such as clubroot and fusarium wilt, is important for successful production of this crop. A clubroot resistance gene on the A3 chromosome of the European winter Brassica napus L. cultivar ‘Mendel’ has been introgressed into Canadian spring canola for the development of clubroot resistant cultivars. However, the spring canol ...

Abstract:
... Grafting tomato (Solanum lycopersicum L.) onto disease resistant rootstocks has grown in use in North America over the past two decades. Rootstocks have traditionally been bred and used for their resistance packages to numerous soil-borne diseases but some rootstocks appear to improve scion yield and vigour in comparison to non-grafted plants in conditions lacking disease challenge. In this study, ...

Abstract:
... Eliminating negative plant-soil feedback (NPSF) in agricultural production systems is the key step in maintaining soil health and sustainable crop production. Sanqi (Panax notoginseng) has been severely hampered by NPSF due to the build-up of soilborne pathogens and the accumulation of autotoxic ginsenosides. Steaming on soil followed by adding biochar was investigated. Greenhouse experiments demo ...
