چکیده
Protium subserratum (Burseraceae) is a neotropical tree species that is comprised of several habitat-specific ecotypes having distinct defense chemical profiles. A previously unknown triterpene, 25,30-dicarboxy-26,27,28,29-tetraacetoxy-10,11,14,15-tetrahydrosqualene, was isolated from P. subserratum young leaf tissue of one ecotype growing in Peru. The structure of 1 was determined by spectroscopic study, including 1 and 2D nuclear magnetic resonance experiments.

Ecological Divergence and Reproductive Isolation in an Amazonian Tropical Tree: Protium
Premise of the study: The first microsatellite primers were developed for Protium subserratum (Engl.) Engl., a widespread Amazonian tree, to investigate genetic differentiation between populations found on clay, brown-sand and white-sand soils. Methods and Results: Seventeen primer pairs were identified from two individuals of Protium subserratum, found on white-sand and brown-sand soil types. ...
متن کاملEvidence for ecological divergence across a mosaic of soil types in an Amazonian tropical tree: Protium subserratum (Burseraceae).
Soil heterogeneity is an important driver of divergent natural selection in plants. Neotropical forests have the highest tree diversity on earth, and frequently, soil specialist congeners are distributed parapatrically. While the role of edaphic heterogeneity in the origin and maintenance of tropical tree diversity is unknown, it has been posited that natural selection across the patchwork of s...
