Recently, it was shown that the distribution of phosphate acquisition genes did not match the 16S rRNA phylogeny among isolates from this group but rather appeared related to phosphate availability where the strains had been isolated. To further understand adaptation to phosphate limitation in Prochlorococcus, the distribution of phosphate acquisition genes was investigated in different ocean regions and related to local ortho-phosphate concentration. In regions characterized by less than 0.1 mu M phosphate, most Prochlorococcus cells contain genes involved in phosphate uptake, regulation and utilization of organic phosphates. In contrast, most of these genes are absent in regions with more than 0.1 mu M phosphate with the exception of genes involved in transport of phosphate (phoE and pstABCS) and three genes of unknown function. This pattern of phosphate acquisition genes showed no significant correspondence to the distribution of rRNA phylotypes. In addition, it was demonstrated that several genes in a separate genomic island were commonly present in low-P sites while absent in high-P sites. Overall, this study further demonstrates a linkage between environmental conditions in the ocean and genome content of Prochlorococcus.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">ISI:000266597200003</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;ISI Document Delivery No.: 453GATimes Cited: 8Cited Reference Count: 25Cited References:      BOYER TP, 2006, WORLD OCEAN DATABASE     COLEMAN ML, 2006, SCIENCE, V311, P1768, DOI 10.1126/science.1122050     FELSENSTEIN J, 1989, CLADISTICS, V5, P164     IKEYA T, 1997, MAR BIOL, V129, P195     JOHNSON ZI, 2006, SCIENCE, V311, P1737, DOI 10.1126/science.1118052     KARL DM, 1992, LIMNOL OCEANOGR, V37, P105     KETTLER GC, 2007, PLOS GENET, V3, P2515, ARTN e231     LI WZ, 2006, BIOINFORMATICS, V22, P1658, DOI     10.1093/bioinformatics/btl158     LUDWIG W, 2004, NUCLEIC ACIDS RES, V32, P1363, DOI 10.1093/nar/gkh293     MARTINY AC, 2006, P NATL ACAD SCI USA, V103, P12552, DOI     10.1073/pnas.0601301103     MARTINY AC, 2009, ENVIRON MICROBIOL, V11, P823, DOI     10.1111/j.1462-2920.2008.01803.x     MOORE JK, 2002, DEEP-SEA RES PT II, V49, P463     MOORE LR, 1998, NATURE, V393, P464     MOORE LR, 2002, LIMNOL OCEANOGR, V47, P989     MOORE LR, 2005, AQUAT MICROB ECOL, V39, P257     PALENIK B, 2006, P NATL ACAD SCI USA, V103, P13555, DOI     10.1073/pnas.0602963103     ROCAP G, 2003, NATURE, V424, P1042, DOI 10.1038/nature01947     RUSCH DB, 2007, PLOS BIOL, V5, P398, ARTN e77     SANUDOWILHELMY SA, 2001, NATURE, V411, P66     SHALAPYONOK A, 2001, DEEP-SEA RES PT II, V48, P1231     SULLIVAN MB, 2005, PLOS BIOL, V3, P790, ARTN e144     THINGSTAD TF, 2005, SCIENCE, V309, P1068, DOI 10.1126/science.1112632     TIMMERMANS KR, 2005, J SEA RES, V53, P109, DOI     10.1016/j.seares.2004.05.003     WEST NJ, 1999, APPL ENVIRON MICROB, V65, P2585     WU JF, 2000, SCIENCE, V289, P759Martiny, Adam C.
