Four terpene synthases contribute to the generation of chemotypes in tea tree (Melaleuca alternifolia)

Padovan A, Keszei A, Hassan Y, Krause ST, Köllner TG, Degenhardt J, Gershenzon J, Külheim C, Foley WJ BMC Plant Biology, 2017 BACKGROUND: Terpene rich leaves are a characteristic of Myrtaceae. There is significant qualitative variation in the terpene profile of plants within a single species, which is observable as “chemotypes”. Understanding the molecular basis… Read more »

Effect of various essential oils isolated from Douglas fir needles upon sheep and deer rumen microbial activity

Oh HK, Sakai T, Jones MB, Longhurst WM Applied microbiology, 1967 ABSTRACT: The effects of essential oils isolated from Douglas fir needles on sheep and deer rumen microbial activity were tested by use of an anaerobic manometric technique. Rumen microorganisms were obtained from a sheep which had been fed mainly on alfalfa hay and dried… Read more »

A review and synthesis of monoterpene speciation from forests in the United States

Gerona C, Rasmussenb R, Arntsc RR, Guentherd A Atmospheric Environment, 2000 ABSTRACT: The monoterpene composition (emission and tissue internal concentration) of major forest tree species in the United States is discussed. Of the 14 most commonly occurring compounds (α-pinene, β-pinene, Δ3-carene, d-limonene, camphene, myrcene, α-terpinene, β-phellandrene, sabinene, ρ-cymene, ocimene, α-thujene, terpinolene, and γ-terpinene), the first… Read more »
