    Origin of the proposal

    In 2010, the Chlorella genome was decoded and the presence of various classes of genes was discovered in this micro alga. An interesting class is the hormone biosynthesis and signaling genes. There was much speculation about the presence of active hormones in algae earlier. But the presence of hormones has been reported in algae in their bioactive form. It is known that hormones like auxin, cytokinin, GA, BR, ABA, JA and polyamines are present in Chlorella.

    Objective

    The question, we are addressing in this project is whether these hormone related genes can be utilized for generating Chlorella lines, which have high efficiency of photosynthesis, improved ability to absorb toxic metals and increased accumulation of biomass along with elucidating the nature of the hormones present in the lower plants. It will also give an answer to whether the phytohormones in algae and higher plants are analogous in their function. Hence manipulation of these genes may cause these lines to become more efficient phytoremediators. Further the potential to increase biomass of Chlorella in a shorter period by affecting genes related to hormones such as auxin and cytokinin is also a possibility as these are the hormones, which regulate cell division and cell differentiation which can be used to increase its prospects for biodiesel production.
