Marine phytoplanktons represent approximately 1% of the Earth's photosynthetic biomass but account for nearly 50% of the net primary productivity of the biosphere. These organisms occupy the euphotic zone of the ocean—the upper, illuminated zone of aquatic ecosystems where photosynthesis is possible. High light adapted species, such as Synechococcus species, occupy the nutrient-poor, light-rich upper 25 m of the zone where white/blue-green light is available. Low light adapted species are

Marine protist has acquired genes from several sources through lateral gene transfer

Was a poem written over a millennium ago the first written record of a plant virus?

Nitrogen starvation triggers signal transduction pathways that result in Chlamydomonas reinhardtii entering a cycle of sexual reproduction. A second signal cascade is triggered by blue light and results in the completion of gametogenesis. Two photoreceptors that respond to the blue region of the spectrum have been identified in C. reinhardtii and are encoded by the phototropin and cryptochrome genes Phot and CPH1, respectively.

Differences in the regulation of flowering between short- and long-day plants.

A complex amino acid cycle is essential for nitrogen fixation in pea nodules.

Plant roots support an array of microorganisms that can have either a deleterious or beneficial impact on plant health and growth. The use of beneficial microorganisms, called plant growth-promoting rhizobacteria (PGPR), increases plant growth and crop yield. In the March 31 Proceedings of the National Academy of Science, Choong-Min Ryu and colleagues from Auburn University, Alabama, US, show that some PGPRs release a blend of airborne chemicals — volatile organic compounds (VOCs) —
