Drug and chemical toxicology (New York, N.Y. 1978), 2020
The venom of Crotalus ornatus (vCo) poses a threat to human health, as it contains a mixture of toxins that can cause cytotoxic, necrotic, and hemolytic effects. The present study assessed methanolic and acetone extracts from leaves and flowers of Larrea

Ultrastructure and Development of the Trichomes of Larrea (Creosote Bush)
Botanical Gazette, 1979Ultrastructural observations indicate that, during development, the single-celled trichomes on the young leaves, petioles, and stipules become isolated from symplastic and apoplastic continuity with other leaf cells. This occurs with the development of a suberin layer internal to the primary wall of the trichome.

Spatial distribution of creosote bush and burrobush in the Mojave and Sonoran Deserts
, 2013 Background/Question/Methods The vegetation of the Sonoran and Mojave deserts is characterized by widespread shrublands dominated by Larrea tridentata (creosote bush) and Ambrosia dumosa (burrobush). These shrub species create fertility islands that influence the distribution of native and invasive annual plants.

Contact dermatitis from Larrea (creosote bush)
Journal of the American Academy of Dermatology, 1986Six men suffering from acute dermatitis had positive patch tests to Larrea (creosote bush). The lesions preferentially involved sun-exposed sites, simulating a photodermatitis, but also were on the legs and scrotum. Our findings were more consistent with contact allergy than with a primary irritant or a phototoxic response.

FUNGICIDAL COMPONENTS OF CREOSOTE BUSH RESIN
1979Abstract Resins obtained by solvent extraction (chloroform and ethanol) of creosotebush, Larrea tridentata , were shown to have anti-fungal action in four different fungi: Rhizoctonia solani, Fusarium oxisporum, Phytium spp ., and Rhizopus nigricans .

Detoxification in Relation to Toxin Tolerance in Desert Woodrats Eating Creosote Bush
Journal of Chemical Ecology, 2001We studied the relationship between the use of three detoxification pathways and urine pH and the tolerance of desert woodrats from two populations to a mixture of naturally occurring plant secondary metabolites (mostly phenolics) in resin from creosote bush (Larrea tridentata). The two populations of desert woodrats came from the Mojave desert (Mojave

Livestock Effects on Genetic Variation of Creosote Bushes in Patagonian Rangelands
Environmental Conservation, 2018SummaryGenetic diversity is the raw material for species’ persistence over time, providing the potential to survive stochastic events, as well as climate and/or human-induced environmental changes. Biodiversity in dry rangelands is decreasing due to intensification of livestock production, but its effects on the genetic diversity of the consumed biota ...

Creosote Bush and the Lower Sonoran Zone of the Southwest
American Midland Naturalist, 1938Creosote Bush (Larrea divaricata Cav.)I is among the most reliable of "indicators" of natural biologic areas in the Southwest, delimiting the Lower Sonoran Zone fairly sharply. The recent articles2 on the effect of sustained subzero weather upon Larrea in the Virgin River Valley of Utah suggest certain earlier studies made upon this shrub.

Lignans from Larrea tridentate (creosote bush) as fungal β-1,3-glucanase inhibitors
Pesticide Biochemistry and Physiology, 2009The enzyme β-1,3-glucanase has a physiological role in morphogenetic-morpholytic processes during fungal development and differentiation. This fungal enzyme has been demonstrated to be involved in fungal pathogen-plant interactions during pathogen attack; therefore fungal β-1,3-glucanase is a biological target for the development of new target-oriented
