Welcome to Prochlorococcus Portal

One of the goals of the Chisholm Lab is to develop Prochlorococcus, and its phage, as a model system for Integrative Systems Biology. Advances in sequencing and high-throughput technologies have begun to generate massive databases of microbial genes and transcriptomes in the oceans, and we are fortunate that Prochlorococcus genes are well represented in these data bases.

In addition, genomes of cultured isolates of Prochlorococcus, and the phage that infect them, are growing in number, as are microarray experiments to examine gene expression. The goal of this public website is to provide easy access to this growing database of Prochlorococcus.

Release Notes

The ProPortal database has been updated with new (Version 3) gene cluster definitions described in:

Kelly, L., Ding, H., Huang, K.H., Osburne, M.S., and Chisholm, S.W. (2013). Genetic diversity in cultured and wild marine cyanomyoviruses reveals phosphorus stress as a strong selective agent. The ISME Journal 7, 1827-1841.

Both the original (Version 1) and new (Version 3) clusters can be accessed via the "COG" menu in the upper right corner of the genome such as AS9601 and cluster pages such as CyCOG2345. Please take note that the desired version has been selected for your particular needs. The Version 3 cluster definitions can also be downloaded from here.
