Trypanocidal activity of oleoresin and terpenoids isolated from Pinus oocarpa.
Fractionation with n-hexane/ethyl acetate (1:1 v/v) by open column chromatography of the oleoresin from Pinus oocarpa Schiede yielded two diterpenes, pimaric acid (1) and dehydroabietic acid (5), the sesquiterpene longifolene (3) and a diterpenic mixture containing pimaric acid (1), isopimaric acid (4) and dehydroabietic acid (5). Subsequently, the isolated compounds, the mixture of 1, 4 and 5,...
متن کاملInduced 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 کاملInitiation of somatic embryogenesis from immature zygotic embryos of oocarpa pine (Pinus oocarpa Schiede ex Schlectendal).
The focus of the current project was to establish somatic embryogenesis protocols for the tropical pine species Pinus oocarpa using immature zygotic embryos (ZEs) as explants. Somatic embryogenesis is best supported by mimicking natural seed-embryo developmental conditions, through a tissue culture medium formulation based on the mineral content of the seed nutritive tissue [megagametophyte (MG...
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 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...
