Brassica oleracea Genomics Project
is one of the most important vegetables in the world. As a member
of Brassica family, Brassica oleracea is the closest
crop relatives to Brassica nupas and Brassica juncea.
So, it's very meaningful to get genome of
Brassica oleracea for Brassica family. In this project,
whole-genome shotgun (WGS) sequencing strategy, based on paired
short reads generated by second-generation Illumina GA sequencing
technology, was used to assemble the draft genome of
Brassica oleracea. So far, 630Mb genome sequence was obtained,
with scaffold N50 size 1.457Mb and contig N50 size 26.828Kb.
Until now, the nine psuedochromosomes of genome assembly, gene prediction and function
annotation are already completed. The study of biological function
is under going. Via the genomic and genetic information of
Brassica oleracea, to study the genus Brassica becoming
very conveniently. Hence,
Brassica oleracea genetics project not only improve development
of genetics and molecular biology but also can accelerate process of
|Introduction to Bolbase
The Brassica oleracea Genome
was designed to provide users a useful and unique genome data
source in the field of studying Brassica oleracea. In
this database, it contained two important sections. First, it supplied genomic data and genomic components data, for genomic data, it mainly contains genome structure, scaffold sequences, and psuedochromosome
sequences; for genomic components data, it mainly includes putative protein-coding genes (gene location,
gene structure, protein feature, gene functional annotation, orthologs and syntenic regions), repeats elments (type, classification, location and sequences) and predicted non-coding RNAs (type, classification, location, description and sequences), and so
it provides thorough analysis on syntenic regions and triplicated
blocks for Brassica oleracea, Brassica rapa and
Arabidopsis thaliana. All of the data can be downloaded on line very
conveniently. This database also provided browse, search,
download, manual, sitemap, and manual of web server. All
of data information will update constantly. It's a useful database
for scientific research in the genetics and molecular
