The chemical communication network among plants

Although the ability to communicate seems to be the exclusive domain of the animal world, plants have also developed a complex way of transmitting information.

💨 This communication addresses the synthesis and release of volatile organic compounds (VOCs), which are low molecular weight metabolites with high vapor pressure.

➡️ Two types of communication can be distinguished, including:

• intraspecific - between individuals of the same species,

• interspecific - between individuals of different species.

⚔️ The production of volatile organic compounds is intended to elicit desired responses from other plants.

🚨 The types of signals emitted vary depending on the circumstances, but most often they serve to:

• attract pollinators or seed dispersers,

• repel pests,

• engage in interspecific competition,

• and warn against herbivores.

🍃 Nearly all plant tissues release VOCs, but they are most commonly produced in the leaves and roots.

🐛 Leaves produce compounds such as terpenoids, methyl jasmonate, methyl salicylate, and others. Their function is to attract animals and repel pests.

🦌 In contrast, VOCs synthesized in the roots, namely sesquiterpenes, sulfur compounds, and ethylene, serve to compete with and warn neighboring plants.

🛡️ Understanding the chemical communication network of plants can help develop new, effective methods for plant protection and cultivation.
