Heavy metal such as copper acts as stress to plants if present in excess concentration in soil and thereby badly affects the plant physiology. In the present work, efforts has been made to study the role of major flowering time genes in tolerance of copper stress in mutants of Arabidopsis thaliana by sowing their seeds in soil and then exposing them to varying concentrations (0μM, 25µM, and 150µM) of copper sulfate solution after an adequate period of growth and development. Recent work has started to uncover molecular mechanisms that govern the process of photoperiodic flowering in Arabidopsis thaliana. The results obtained were compared to that of wild type (col-0). It facilitates the assessment of essential morphological features affected by copper stress such as bud development, flowering time, various symptoms associated with excess copper uptake and chlorophyll density in a single experiment. This study was quite useful in determining the potential of these mutants for use in phytoremediation. This can lead to decrease in the accumulation of heavy metals in the soil thereby enhancing the fertility of the soil and significant increase in the agricultural productivity.
