Genome

Brassica rapa (field mustard) Subspecies include several important vegetable crops like turnip and Chinese cabbage Lineage: Eukaryota[13303]; Viridiplantae[1443]; Streptophyta[1342]; Embryophyta[1333]; Tracheophyta[1315]; Spermatophyta[1299]; Magnoliopsida[1275]; eudicotyledons[1029]; Gunneridae[1029]; Pentapetalae[1029]; rosids[649]; malvids[260]; Brassicales[94]; Brassicaceae[90]; Brassiceae[22]; Brassica[9]; Brassica rapa[1]

The genus Brassica includes several economically important plants. They are used as vegetables, fodder, and as a source of vegetable oil and condiments. Several species are rich in vitamins and anti-carcinogenic compounds. There are six Brassica species growing throughout the world. Three of those are diploid - B. rapa (AA genome More...type, 2n=20), B. nigra (BB genome type, 2n=16), and B. oleracea (CC genome type, 2n=18) which have hybridized to give rise to three amphidiploids, B. napus (AACC, 2n=38), B. juncea (AABB, 2n=36), and B. carinata (BBCC, 2n=34). These different species exhibit different morphological characteristics. Many groups throughout the world have been working on various aspects of Brassica genome. In 2002 it was decided to integrate various Brassica projects under the Multinational Brassica Genome Project. B. rapa subsps pekinensis (Chinese cabbage) is a popular vegetable in East Asia and so commercially important. It is a diploid plant with a genome size of about 500 Mb. The Multinational Brassica Genome Project committee has decided to sequence the genome of B. rapa. It has a smaller genome compared to the genomes of B.oleracea or B. napus and BAC libraries providing greater than 20 fold coverage are available. Less...
