| Abstract: | "Plant glandular trichomes are able to secrete and store large amounts of volatile organic compounds (VOCs). VOCs typically accumulate in dedicated extracellular spaces, which can be either subcuticular, as in the Lamiaceae or Asteraceae, or intercellular, as in the Solanaceae. Volatiles are retained at high concentrations in these storage cavities with limited release into the atmosphere and without re-entering the secretory cells, where they would be toxic. This implies the existence of mechanisms allowing transport of VOCs to the cavity but preventing their diffusion out once they have been delivered. The cuticle and cell wall lining the cavity are likely to have key roles in retaining volatiles, but their exact composition and the potential molecular players involved are largely unknown" |
