Induced resistance and associated defence gene responses in Pinus patula
Background Plants are able to incite a type of broad spectrum resistance against pathogens upon pre-treatment with biological or chemical inducers. Systemic Acquired Resistance (SAR) and Induced Systemic Resistance (ISR) are two types of induced resistance which lead to the accumulation of specific pathogenesis-related (PR) proteins. Non-pathogenic rhizobacteria are inducing agents for ISR and ...
متن کاملAnaerobic Xylanolytic Bacterium from Decayed Pinus patula Wood Chips
An anaerobic, mesophilic, sporeforming, xylanolytic bacterium was isolated from decayed Pinus patula wood chips. The cells of this organism were gram-negative rods, had peritrichous flagella, and formed terminal round endospores which distended the cell wall. Xylan, cellobiose, fructose, glucose, maltose, mannose, melezitose, raffinose, rhamnose, salicin, sucrose, and xylose were utilized. The ...
متن کاملNovel taxa in the Fusarium fujikuroi species complex from Pinus spp.
The pitch canker pathogen Fusarium circinatum has caused devastation to Pinus spp. in natural forests and non-natives in commercially managed plantations. This has drawn attention to the potential importance of Fusarium species as pathogens of forest trees. In this study, we explored the diversity of Fusarium species associated with diseased Pinus patula, P. tecunumanii, P. kesiya and P. maximi...
متن کاملSources of Diplodia pinea endophytic infections in Pinus patula and P. radiata seedlings in South Africa
Diplodia pinea, an opportunistic and latent pathogen, can significantly affect Pinus productivity worldwide. Despite being studied in South Africa for almost 100 years, the source of D. pinea inoculum responsible for seedling infection is unknown. The aim of this study was to determine the role of seed in vertical transmission of D. pinea and to investigate sources of inoculum leading to horizo...
متن کاملEvaluation of the heat pulse velocity method for measuring sap flow in Pinus patula
Information on the water use of Pinus patula plantations is required to predict the impact of forest plantations on water resources in South Africa. The heat pulse velocity (HPV) method is a promising technique for measuring water use by trees, and has been shown to measure sap flows accurately in a variety of hardwood trees. This method has not been sufficiently verified for pine trees where t...
