| Abstract | ||
| Diatoms considered as are a phytoplankton main group of in aquatic ecosystems abundance, diversity, and productivity. Allelopathic infractions, are an important part of phytoplankton competition, allelopathy may be one of the factors affecting the structure of phytoplankton. Diatoms are known to produce a number of allelopathic compounds, such as polyunsaturated fatty acids (PUFAs), polyunsaturated aldehydes (PUAs) and polyphenolic and halogenated compounds. However, Allelochemicals (AC) are chemical substances produced by diatoms and release which affecting microorganisms in their neighborhood. These chemicals are able to prevent or encourage the co-occurring phytoplankton species growth along other organisms. Such sintering behavior affecting not just each species that replying to or making a definite chemical, but as well functioning of communities, populations, and ecosystems including defense, reproduction, competition, and predator avoidance. The current review demonstrates work of Allelopathy in diatoms and stimulated or excreted chemicals via diatom direct or indirect way to environment for maintaining their domination. | ||
