Green may have been the Pantone Color of the Year for 2013 (http://www.pantone. com/color-of-the-year-2013), but 2016was a great year for articles on chlorophyll research at The Plant Cell and beyond. In this year, we saw a pile of interesting articles examining chlorophyll degradation, including its regulatorymechanisms.Forexample, to identify transcription factors upstream of the key enzyme p...

Total nitrogen (TN) and total phosphorus (TP) measurements and contemporaneous measurements of chlorophyll a (Chl a) and phytoplankton nutrient deficiency have been made across a broad range of lakes and ocean sites using common methods. The ocean environment was nutrient rich in terms of TN and TP when compared with most lakes in the study, although Lake Victoria had the highest values of TN a...

Although picophytoplankton (PP) (0.2-2 µm) are ubiquitous in lakes and oceans, their importance in rivers has rarely been studied. We examined PP assemblages during the ice-free period in five rivers of a temperate region varying in trophic state (9-107 µg/L total phosphorus) and water discharge (1-87 m3/s). In these rivers, PP abundance reached concentrations as high as those observed in lakes...

Bacterioplankton numbers, biomasses, and productivities, as well as chlorophyll a concentrations and phytoplankton productivities, were assayed from 1 March 1984 to 12 August 1985 through a 250-m-deep seawater column in Howe Sound, a temperate fjord-sound on the southern coast of British Columbia, Canada. Primary production during this 18-month period was 845 g of C m. Bacterial production was ...

Impact of three different cyclones on the Bay of Bengal water and its surface chlorophyll concentration has been studied in three different zones during October-December 2000 using 24 scenes of IRS-P4 Ocean Color Monitor (OCM). The chlorophyll concentration found to be increasing up to 5.0 mg/m with effect of cyclones and hurricanes. The data has been correlated with Sea Surface Temperature (SS...
