About the Genome

Pea (Pisum sativum L., 2n = 14) is a valuable source of dietary proteins, mineral nutrients,which was domesticated ~10,000 years ago by Neolithic farmers of the Fertile Crescent. It has been studied as a genetic model since the discovery of Mendel's law of inheritance. Here, we de novo assembled a Chinese pea variety genome named ‘PeaZW6’ and the assembly spans 3.79 Gb representing ~ 88.55 % of the estimated pea genome size (~4.28 Gb) by Flow cytometer. Meanwhile, we integrated RNA-seq data of 8 different pea tissues, and predicted 47526 genes. This high-quality pea genome will greatly promote molecular genetics research and breeding improvement of pea.
