Chemical defense against insects in Heterotheca subaxillaris and three Orobanchaceae species using exudates from trichomes.
Morimoto M. Morimoto M. Pest Manag Sci. 2019 Sep;75(9):2474-2481. doi: 10.1002/ps.5395. Epub 2019 Apr 5. Pest Manag Sci. 2019. PMID: 30828973
They show antimicrobial and insecticidal activities, and they have also been isolated and identified from wild plants. RESULTS: The Asteraceae species Heterotheca subaxillaris has many glandular trichomes on the leaf surface, and these contain sesquiterpene c …

Trade-off between dispersal traits in a heterocarpic plant across its invasion route.
Robinson D, Bogdanova T, Cohen O, Gruntman M. Robinson D, et al. Am J Bot. 2023 Jul;110(7):e16192. doi: 10.1002/ajb2.16192. Epub 2023 Jun 27. Am J Bot. 2023. PMID: 37210746
METHODS: This study examined the interplay between dispersal ability and dispersal rate across the invasion route of the heterocarpic plant Heterotheca subaxillaris. Capitula of H. subaxillaris were collected from eight populations along its invasion route in …

Phytotoxicity of constituents of glandular trichomes and the leaf surface of camphorweed, Heterotheca subaxillaris.
Morimoto M, Cantrell CL, Libous-Bailey L, Duke SO. Morimoto M, et al. Phytochemistry. 2009 Jan;70(1):69-74. doi: 10.1016/j.phytochem.2008.09.026. Epub 2008 Dec 4. Phytochemistry. 2009. PMID: 19054533
Camphorweed, Heterotheca subaxillaris (Lam.) Britt. & Rusby, has a camphor-like odor, and its leaf surfaces contain glandular trichomes of the type shown to contain high levels of isoprenoids in other species. ...

Pollination effectiveness and pollinator importance in a population of Heterotheca subaxillaris (Asteraceae).
Olsen KM. Olsen KM. Oecologia. 1996 Dec;109(1):114-121. doi: 10.1007/PL00008811. Oecologia. 1996. PMID: 28307601
This study examined pollinator activity and seed set in a population of Heterotheca subaxillaris, a species that exhibits a floret dimorphism (heads bearing disk and ray florets), and that is visited by both generalist foragers and specialist bees. ...The single spe …

Growth pattern and carbon allocation to volatile leaf terpenes under nitrogen-limiting conditions in Heterotheca subaxillaris (Asteraceae).
Mihaliak CA, Lincoln DE. Mihaliak CA, et al. Oecologia. 1985 Jun;66(3):423-426. doi: 10.1007/BF00378309. Oecologia. 1985. PMID: 28310873
Rosettes of Heterotheca subaxillaris were grown at four levels of nitrate. Individual leaf volatile mono- and sesquiterpene content, leaf nitrogen content, and root and shoot dry weight were measured on individual leaves every two weeks for 18 weeks. ...
