Currently, majority of allelopathic studies focus on
negative effects exerted by one species on another,
however, understanding the stimulation effect of some
allelochemicals for the normal growth and development
of some groups would have great contribution in
developing mitigation mechanisms for harmful blooming
algae and invasive macrophytes. Also, elucidating the reciprocal or counter act mechanisms of target
phytoplankton to allelochemicals are still ill-defined and it
could be possible future research areas. Reciprocal
allelopathic responses between macrophytes and other
phytoplankton species would have implications for the
management of eutrophic waters. Majority of reports
have indicated that allelochemicals negatively influence
the growth and physiological processes such as enzyme
activities and photosynthesis. Therefore, understanding
the molecular mechanisms and the genetic bases of such
effect is important. In addition to these, the molecular and
genetics bases of allelopathy of invasive species of AMs
are not well studied and utilizing the outputs to develop
potential control is done through engineering.
