plants produce an array of peptides as part of their innate defense mechanism against pathogens. the potential use of these peptides for various therapeutic purposes is increasing per diem. in order to excel in this research, the community requires web repositories that provide reliable and accurate information about these phyto-peptides. this work is an attempt to bridge the gaps in plant-based peptide research. PlantPepDB is a manually curated database that consists of 3848 plant-derived peptides among which 2821 are experimentally validated at the protein level, 458 have experimental evidence at the transcript level, 530 are predicted and only 39 peptides are inferred from homology. incorporation of physicochemical properties and tertiary structure into plantpepDB will help the users to study the therapeutic potential of a peptide, thus, debuts as a powerful resource for therapeutic research. Different options like Simple, Advanced, PhysicoChem and AA composition search along with browsing utilities are provided in the database for the users to execute dynamic search and retrieve the desired data. interestingly, many peptides that were considered to possess only a single property were found to exhibit multiple properties after careful curation and merging the duplicate data that was collected from published literature and already available databases. Overall, PlantPepDB is the first database comprising detailed analysis and comprehensive information of phyto-peptides from a broad functional range which will be useful for peptide-based applied research. plantpepDB is freely available at http://www.nipgr.ac.in/plantpepDB/.The past decade has seen exceptional growth in peptide-based therapeutic research. Currently, over 60 peptide drugs are approved in the market 1 and more than 200 peptide drugs are in different clinical trial phases 2 . These numbers clearly denote the applicability of peptide-based therapeutics in the field of drug discovery 3 . Higher as well as the lower group of plants possess a broad range of defense mechanisms to combat chemical, physical and biological stress conditions. Plant-derived peptides are one of their defensive approaches. Bioactive plant peptides are an underexplored domain in the field of proteomics and peptidomics 4 . Plenty of bioactive peptides, including toxins and venoms that act upon intriguing molecular targets, have been identified in all plant taxonomic groups. Plant-derived peptides possess numerous activities like antifungal, antibacterial, antiviral, anticancer, antihypertensive, immune system related, antiparasitic, antifeedant, insecticidal, etc., that can be utilized for many therapeutic and biological applications. Over the last few years, peptides emerged as an alternative for chemical drugs due to the change in drug development and treatment paradigms 1 . Therapeutic peptides are advantageous over proteins or antibodies as they have high target specificity and selectivity as well as easy to synthesize 5 , and are less toxic. Plant peptides may be a starting p...
