“…Prior reports described antifungal activities of plants EOs and several of their individual components against some of the pathogens examined in our work and demonstrated that the mechanisms involved in control of these pathogens by plant EOs include restriction of their conidial germination and hyphal growth (Marei et al, 2012;Pérez-Alfonso et al, 2012;Regnier et al, 2014;Zhou et al, 2014;Tao et al, 2014). For example, Ameziane et al (2007) found that T. leptobotrys EO inhibited in vitro completely (100%) the mycelial growth of the three fungal pathogens.…”

“…The role of camphor (Kotan et al 2007;Marei et al 2012;Pragadheesh et al 2013;Ramsewak et al 2003) is ambiguous, being inhibitory for some fungi but not others, suggesting slight fungal toxicity. α-Terpineol, however, is a powerful fungal inhibitor ( Cakir et al 2004;Hammer et al 2003;Kossuth and Barnard 1983;Kotan et al 2007;Kusumoto et al 2014;Zhou et al 2014). Thymyl methyl ether is among the least inhibitive chemical structures of thymol to several fungi (Kumbhar and Dewang 2001).…”

Seiridium cardinale, the main fungal pathogen responsible for cypress bark canker, is the largest threat to cypresses worldwide. The terpene response of canker-resistant clones of Italian cypress, Cupressus sempervirens, to two differently aggressive isolates of S. cardinale was studied. Phloem terpene concentrations, foliar terpene concentrations, as well as foliar terpene emission rates were analyzed 1, 10, 30, and 90 days after artificial inoculation with fungal isolates. The phloem surrounding the inoculation point exhibited de novo production of four oxygenated monoterpenes and two unidentified terpenes. The concentrations of several constitutive mono-and diterpenes increased strongly (especially α-thujene, sabinene, terpinolene, terpinen-4-ol, oxygenated monoterpenes, manool, and two unidentified diterpenes) as the infection progressed. The proportion of minor terpenes in the infected cypresses increased markedly from the first day after inoculation (from 10 % in the control to 30-50 % in the infected treatments). Foliar concentrations showed no clear trend, but emission rates peaked at day 10 in infected trees, with higher δ-3-carene (15-fold) and total monoterpene (10-fold) emissions than the control. No substantial differences were found among cypresses infected by the two fungal isolates. These results suggest that cypresses activate several direct and indirect chemical defense mechanisms after infection by S. cardinale.

“…Several monoterpenes are known to inhibit root and shoot growth, respiration and photosynthesis, decrease cell wall permeability, or interfere with hormone activity (Abrahim et al 2000;Graña et al 2013a). Among monoterpenes, citral was found to inhibit seed germination (Dudai et al 2000), having herbicide potential for weeds (Graña et al 2013b), together with anti-fungal (Zhou et al 2014), antibacterial (Apol onio et al 2014) and nematocidal (Mukherjee & SinhaBabu 2014) activities. Monoterpenes also inhibit microtubule polymerisation in plant cells (Chaimovitsh et al 2010) through arresting cell division, causing root malformations mediated by an alteration in auxin and ethylene content in Arabidopsis thaliana ).…”

Terpenoid trans‐caryophyllene inhibits weed germination and induces plant water status alteration and oxidative damage in adult Arabidopsis

et al. 2016

trans-Caryophyllene (TC) is a sesquiterpene commonly found as volatile component in many different aromatic plants. Although the phytotoxic effects of trans-caryophyllene on seedling growth are relatively explored, not many information is available regarding the phytotoxicity of this sesquiterpenes on weed germination and on adult plants. The phytotoxic potential of TC was assayed in vitro on weed germination and seedling growth to validate its phytotoxic potential on weed species. Moreover, it was assayed on the metabolism of Arabidopsis thaliana adult plants, through two different application ways, spraying and watering, in order to establish the primary affected organ and to deal with the unknown mobility of the compound. The results clearly indicated that TC inhibited both seed germination and root growth, as demonstrated by comparison of the ED50 values. Moreover, although trans-caryophyllene-sprayed adult Arabidopsis plants did not show any effect, trans-caryophyllene-watered plants became strongly affected. The results suggested that root uptake was a key step for the effectiveness of this natural compound and its phytotoxicity on adult plants was mainly due to the alteration of plant water status accompanied by oxidative damage.
