The Genome Atlas of Bamboo and Rattan (GABR) project has yielded a new chromosome-level genome assembly of moso bamboo (Phyllostachys edulis) and two representative rattan genomes—Calamus simplicifolius and Daemonorops jenkinsiana. The results are published in GigaScience.
Using Illumina, PacBio and Hi-C sequencing data, the researchers were able to generate a chromosome-level genome assembly of moso bamboo. The same technology was applied to obtain the first two representative rattan genomes for C. simplicifolius and D. jenkinsiana, which together represent more than 95 percent of the canes produced by the rattan industry.
In addition, researchers constructed a comprehensive alternative splicing atlas for bamboo species. Combing large-scale transcriptomic sequencing of 26 representative bamboo tissues, they identified 266,711 unique alternative splicing events in 25,225 genes. These genes were found to be conserved in related plant species, were more highly expressed and less tissue specific in their pattern of expression.
