Unravelling the signaling pathways involved in the production of secondary metabolites that are responsible for stress tolerance in plants is the main aim of Dr. Rabia’s research group. Secondary metabolites are generally known as plant ‘natural products’ and represent a vital field of study. These secondary metabolites not only confer stress tolerance in plants but also impart medicinal properties to them. Plants often accumulate their natural products at relatively low levels, so there is a lot of interest in breeding or engineering plants that produce higher levels. It has been shown that the most effective way to increase the accumulation of secondary metabolites is to increase the activity of genes that regulate the activity of the biosynthetic pathways that make different natural products. Regulatory genes of this type encode proteins that are called transcription factors. The biggest bottleneck in using this strategy to develop plants that accumulate significantly higher levels of important natural products. Many transcription factors regulating secondary metabolism have yet to be identified at the molecular level. It is likely that several of the selected genes encode transcription factors that have the same regulatory activity. These genes will be identified because increasing their activity will result in the same changes in metabolites in plants.
