Black pepper (Piper nigrum L.), widely known as the "king of spices," is an economically significant crop belonging to the Piperaceae family. Beyond its culinary value, black pepper possesses diverse applications in fragrance, traditional medicine, and food preservation due to its bioactive alkaloid, piperine. Piperine exhibits anti-inflammatory, antioxidant, analgesic, antipyretic, antimicrobial, digestive, and cytotoxic properties, underscoring its global importance in food and pharmaceutical industries.
BpCNVDb is a dedicated database for exploring copy number variations (CNVs) in black pepper, derived from whole-genome resequencing (WGS) data of 39 genotypes collected across India. A total of 159,390 CNVs and 11,360 CNV regions (CNVRs) were identified by comparing these WGS datasets with the reference genome. This resource provides chromosome-wise visualization of CNVs and CNVRs, facilitating genotype-specific structural variation information with its functional implications.
BpCNVDb serves as a valuable platform for genetic studies, including genotype identification, genetic diversity assessment, and marker-trait association analysis. By integrating CNV data into breeding programs, researchers can use this database for the identification of genetic variations associated with agronomic traits, aiding in the development of improved black pepper cultivars. The database offers an intuitive interface to assist researchers in retrieving and analyzing CNV information, supporting studies in functional genomics, evolutionary biology, and plant breeding
