Plants synthesize a diversity of low molecular weight, structurally complex chemical compounds, commonly known as secondary metabolites (Moore, Andrew, Kulheim, & Foley, 2014) These are present mainly under stress conditions, but their absence does not cause harmful effects to the plants (Edreva, 2005; Edreva et al., 2008; Khan, Aliabbas, Kumar, & Rajkumar, 2009).
Many factors including stresses like drought, nutrient deficiency and diseases ultimately down regulate the accumulation of secondary metabolites in plants.
