Plantemitted

Plantemitted is a term used to describe compounds released by plants into the environment. These emissions are diverse and serve various functions, playing a crucial role in plant physiology and ecological interactions. The most significant class of plantemitted compounds are volatile organic compounds (VOCs). These are gaseous molecules that can be detected by their odor and are highly reactive.

Plants release VOCs for numerous reasons. Some VOCs act as attractants for pollinators, guiding insects to flowers to facilitate reproduction. Others serve as signals to attract natural enemies of herbivores, essentially calling for help when under attack. Conversely, some VOCs function as repellents, deterring herbivorous insects and other pests. Additionally, VOCs can play a role in plant-to-plant communication, warning neighboring plants of impending threats like insect infestations or drought.

Beyond VOCs, plants also emit other substances. Root exudates, released from plant roots into the soil, are a complex mixture of organic compounds including sugars, amino acids, and organic acids. These exudates can influence the soil microbial community, impacting nutrient availability and plant health. Furthermore, plants can release aerosols and particulate matter, particularly during processes like pollen dispersal or when damaged. The study of plantemitted compounds is an active area of research, contributing to our understanding of plant biology, ecology, and the intricate web of life within ecosystems.
