title: Biogenic volatile organic compounds and plant competition.
abstract: One of the most important factors to shape plant communities is competition between plants, which impacts on the availability of environmental factors such as light, nutrients and water. In response to these environmental parameters, plants adjust the emission of many different biogenic volatile organic compounds (BVOCs). BVOCs can also elicit responses in neighbouring plants, thus constituting a platform for plant-plant interactions. Here, we review the relationship between BVOC emissions and competition among neighbouring plants. Recent progress indicates that BVOCs can act both as allelochemicals and as neighbour detection signals. It is suggested that BVOCs provide information about neighbouring competitors, such as their identity or growth rate, that classic neighbour detection signals cannot provide.
