Abstract

Many plants respond to herbivory by releasing a complex blend of volatiles that may differ from that emitted by intact counterparts. These herbivore-induced plant volatiles (HIPV) mediate many interactions among plants and their community members, including alerting undamaged leaves of the attacked or neighbouring plants to impending danger. It has been postulated that HIPVs evolved for within-plant signalling and that other organisms subsequently evolved to use them. However, only seven studies have reported HIPV-mediated within-plant signalling, most conducted in the laboratory or greenhouse. This leaves open the ecological relevance and evolutionary underpinning of the phenomenon. We recently observed within-plant signalling in hybrid aspen under laboratory and field conditions. Greenhouse experiments showed that HIPVs mediated the process. While our study adds an aspen hybrid to the list of plants in which within-plant signalling has been demonstrated, we lack understanding of how common the process is and whether plants obtain fitness benefits.
