Herbal medicinal plants constitute valuable resources of natural secondary active biomolecules that supplement human nourishment, support health care, and are the backbone of herbal industry. Plant breeders are faced with challenging task to realize qualitative and quantitative improvement in their secondary content using traditional breeding methods. Plant genomics research is fast progressing providing better understanding of the complex genetics and biological chemistry involved in the synthesis of natural secondary biomolecules, thus complementing valuable tools to facilitate genetic enhancement. The goal of the genomics study is to build high-throughput sequencing and genotyping technologies to generate huge genomic resources for gene/QTL mapping and marker-trait association for marker-assisted breeding. It also makes easier to find and isolate genes that are involved in various phases of several biosynthetic processes. Efforts are also being made to construct EST and microarray-based functional databases, which will open up the new possibilities for the rapid enrichment of herbal medicinal plants utilizing smart markers and genetic transformation. Metabolic engineering of endogenous and exotic genes based on genome editing could aid in the modification of biosynthetic pathways in these plants. The present review provides an overview of recent developments, limitations, and future possibilities in herbal medicinal plant molecular breeding, including marker-assisted selection and genetic engineering approaches for genetic improvement.
