Capsicum, commonly referred to as pepper, is an economically important genus of the Solanaceae family which includes tomato and potato. The genus includes at least 32 species native to tropical America, of which C. annuum L., C. baccatum L., C. chinense Jacq., C. frutescens L., and C. pubescens (Ruiz & Pavon) were domesticated as far back as 6000 BC by Native Americans. Peppers have a wide diversity of fruit shape, size and color. Pungent peppers are used as spices and sweet peppers as vegetables. Following the return of Columbus from America in 1492 and subsequent voyages of exploration, peppers spread around the world because of their adaptation to different agroclimatic regions and food, medical and ornamental uses. Global production of pepper in 2010 reached 29.4 million tons of fresh fruit and 3.1 million tons of dried pods produced on 3.9 million hectares (http://www.fao.org). In spite of the growing commercial importance of pepper, the molecular mechanisms that modulate fruit size, shape and yield are mostly unknown.
We sequenced the complete genomes of wild Mexican pepper accession “Chiltepin” and a Chinese inbred derivative “Zunla-1” using the Illumina platform.
As one of the most important vegetable crops, pepper genome will provide an invaluable new resource for biological research and breeding of Capsicum. To better manage the pepper genome data and facilitate public academic users to access the genome data and related information, we developed the Pepper Genome Database.
