Current sampling of genomic sequence data from eukaryotes is relatively poor, biased, and
inadequate to address important questions about their biology, evolution, and ecology; this …

Cell coloration changes from normal blue-green to yellow or yellow-green when the
cyanobacterium Synechococcus sp. strain PCC 7942 is deprived of an essential nutrient. We found …

Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide.
Despite considerable efforts, a comprehensive understanding of the factors that promote …

Phycobilisomes are the multiprotein complexes predominantly responsible for harvesting
light energy in cyanobacteria and some eukaryotic algae. When the cyanobacterium …

Amino acid sequence alignments and phylogenetic analyses have been used to examine the
relationships among 100 phycobiliprotein sequences. The alignments revealed a number …

Urea synthesized commercially and formed naturally as a by-product of cellular metabolism
is an important source of nitrogen (N) for primary producers in aquatic ecosystems. Although …

A modified nested reverse transcriptase PCR (RT-PCR) method was used to detect the
expression of nitrogenase genes in meso-oligotrophic Lake George, New York. Net (>20-μm …

Cyanobacteria are found in virtually all terrestrial niches and can be found in locations which
exhibit widely fluctuating chemical and physical parameters including nutrient availability, …

Diverse microbial ecosystems underpin life in the sea. Among these microbes are many
unicellular eukaryotes that span the diversity of the eukaryotic tree of life. However, genetic …

Flow cytometers measure light scattering and fluorescence characteristics from individual
particles in a fluid stream as they cross one or more light beams at rates of up to thousands of …
