Abstract– The nightshade family Solanaceae is a highly diverse family encompassing several major crop species like Solanum tuberosum, S. lycopersicum, S. melongena, Capsicum, Datura, Atropa, Withania, Nicotiana etc. that are essential for human nutrition, medicine and industry but these crop species are susceptible to pests, pathogens and abiotic stresses. And continued domestication of some crops often leads to decrease in crop yields due to loss of genetic diversity. For the improvement of these crops, molecular phylogenetic analysis act as a road map for finding the genes associated with the productivity, disease resistance and valuable traits. Our present study reviewed various research applications where phylogenetic analysis help in identifying beneficial genes from wild relatives of domesticated economically important Solanaceae species, in exploring the evolutionary origin of genes associated with the biosynthesis of secondary metabolites, in finding genes in the family with similar functions and in CRISPR-CAS genome editing techniques and molecular breeding. All these approaches ultimately enhance crop breeding strategies for the development of disease and pest resistant, stress resilient and high yielding solanaceae crops.
