Abstract The colony-forming cyanobacteria Trichodesmium spp. are considered one of the most important nitrogen-fixing genera in the warm, low nutrient ocean. Despite this central biogeochemical role, many questions about their evolution, physiology,

Warming Iron-Limited Oceans Enhance Nitrogen Fixation and Drive Biogeographic Specialization of the Globally Important Cyanobacterium Crocosphaera

Autor: Nina Yang, Carlin A. Merkel, Yu-An Lin, Naomi M. Levine, Nicholas J. Hawco, Hai-Bo Jiang, Ping-Ping Qu, Michelle A. DeMers, Eric A. Webb, Fei-Xue Fu, David A. Hutchins

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

Primary productivity in the nutrient-poor subtropical ocean gyres depends on new nitrogen inputs from nitrogen fixers that convert inert dinitrogen gas into bioavailable forms. Temperature and iron (Fe) availability constrain marine nitrogen fixation

Mechanisms of increased Trichodesmium fitness under iron and phosphorus co-limitation in the present and future ocean

Autor: Nathan G. Walworth, Fei-Xue Fu, Eric A. Webb, Mak A. Saito, Dawn Moran, Matthew R. Mcllvin, Michael D. Lee, David A. Hutchins

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-11 (2016)

Cyanobacterial nitrogen fixation supplies bioavailable nitrogen to marine ecosystems, but the mechanisms governing iron and phosphorus co-limitation in elevated CO2remain unknown. Here, the authors show a complex cellular response to co-limitation ch

Functional Genomics and Phylogenetic Evidence Suggest Genus-Wide Cobalamin Production by the Globally Distributed Marine Nitrogen Fixer Trichodesmium

Autor: Nathan G. Walworth, Michael D. Lee, Christopher Suffridge, Pingping Qu, Fei-Xue Fu, Mak A. Saito, Eric A. Webb, Sergio A. Sañudo-Wilhelmy, David A. Hutchins

Publikováno v: Frontiers in Microbiology, Vol 9 (2018)

Only select prokaryotes can biosynthesize vitamin B12 (i.e., cobalamins), but these organic co-enzymes are required by all microbial life and can be vanishingly scarce across extensive ocean biomes. Although global ocean genome data suggest cyanobact
