Aquatic Ecosystems, HIPM Processes (Growth)


An exudate is any fluid that filters from the circulatory system into lesions or areas of inflammation. It can apply to plants as well as animals. Its composition varies but generally includes water and the dissolved solutes of the main circulatory fluid such as sap or blood. In the case of blood it will contain some or all plasma proteins, white blood cells, platelets, and in the case of local vascular damage: red blood cells. In plants, it can be a healing and defensive response to repel insect attack, or it can be an offensive habit to repel other incompatible or competitive plants.

-- Exudate (WP)

Healthy phytoplankton cells exude dissolved organic matter (DOM). In a model, DOM exudation is demonstrated to be a cost-effective, indirect, means of reducing virus infection, which can be a major cause of phytoplankton mortality.
