ABSTRACT
The application of molecular, biological and biotechnological approaches have considerable potential in photosynthetic research for a better understanding of the precise mechanisms involved. The physiological, biochemical and biophysical investigations have yielded substantial information on the responses of plants in photosynthetic performance related to environmental variables, including growth light intensity. Several studies involving molecular biology and transgenic technology are available in recent years that can be applied to environmental stresses (Raines and Lloyd, 1996) as also in the area of photosynthesis. In addition, the recently emergent genomic technologies are also being applied to the study of photosynthesis (Pesaresi et al., 2001; Dent et al., 2001). Particular stress is laid on the functional genomics also employing the reverse genetics approach in understanding the function of photosynthetic genes in Arabidopsis, a study that is being vigorously pursued currently (Pesaresi et a l , 2001; Dent et a l , 2001).
