Ppomicsdb: A Multi-Omics Database for Genetic and Molecular Breeding Applications in Pigeonpea

Cajanus cajan, commonly known as Arhar or tur in India, is a highly treasured plant species belonging to the Fabaceae family. Pigeonpea is a drought-tolerant legume crop produced in the world's tropics and subtropics areas, rich source of protein, carbohydrates, fiber, and minerals. It is considered as "meat for vegetarian people" and addresses malnutrition issues globally. Despite its nutritional and economic importance, the lack of comprehensive knowledge about its genomic resources prevents it from being used wisely through molecular breeding programs and biotechnological intervention. Several genomic repositories on pigeonpea are available; however, there is no cohesive integrated multi-omics database available for C. cajan. Here, we present a first report on comprehensive pigeonpea omics database, named as Ppomics database (db) available at , which provides up-to-date various aspects of multi-omics information devoted to the catalogs phenomics (both qualitative and quantitative), genomics, transcriptomics, and proteomics data. Ppomics db is an integrated multi-omics platform for discovering important regulators of several qualitative and quantitative traits in pigeonpea, which can be utilized for superior breed development. Ppomics db has been made available to researchers to acquire the related omics information and perform multi-omics data analysis.
