Biological activities of abscisic acid analogs in the morphological change of the green alga Haematococcus pluvialis
The plant hormone abscisic acid (ABA) induces a morphological change from green vegetative cells to red cyst cells, of Haematococcus pluvialis containing carotenoids, in plate culture. Long-lasting analogs of ABA, (+)-8′,8′,8′-trifluoro and (+)-8′,8′-difluoro-ABAs, which can resist metabolic inactivation, induce carotenoid production at 100-fold lower concentration than (+)-ABA. These analogs can be used as effective regulators to produce carotenoids in H. pluvialis cells.
