Piper nigrum L., black pepper is a perennial vine of the family piperaceae. Black pepper is grown for its fruit which is dried and as a spice for seasoning and also have medicinal uses. Native to Malabar coast in India, it is most traded spice in the. Black pepper have drupe type fruit called peppercorn which contains the chemical compound piperine responsible for its spiciness. Black pepper is a tropical plant requiring high humidity and rainfall and is ideally grown in temperature between 10 to 40 ^oC.

Circular RNAs (circRNAs) and Long non-coding RNAs (lncRNAs) are major classes of the non-coding RNAs found in the cell. while Long non-coding RNAs are linear transcripts longer than 200 nucleotides and have very less or no coding potential, circRNAs are ncRNAs which are circular in shape formed due to the formation covalent bond between the splice acceptor on one end and splice donor on other end called as back-splicing. These have been found to be involved in various regulatory mechanisms in response to stress conditions in plants and animals by affecting the expression of genes in its cis or trans. Both lncRNAs and circRNAs can act as competitive endogenous RNAs (ceRNAs) by interferring miRNA-mRNA interactions. The BPncDB can be used a resource of Black pepper’s ncRNAs specific to tissues viz. Flower, fruit, leaf, panicle, root and stem.
