The pigment-protein network of a diatom photosystem II–light-harvesting antenna supercomplex

open access: yesScience, 2019
A light-harvesting array in diatoms Photosynthetic organisms use huge arrays of pigments to draw light energy into the core of photosystem II. The arrangement of these pigments influences how much energy reaches the reaction center. Pi et al.

Chytridiomycosis of marine diatoms : the role of stress physiology and resistance in parasite-host recognition and accumulation of defense molecules [PDF]

open access: yes, 2017
Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...

Associated bacteria affect sexual reproduction by altering gene expression and metabolic processes in a biofilm inhabiting diatom [PDF]

open access: yes, 2019
Diatoms are unicellular algae with a fundamental role in global biogeochemical cycles as major primary producers at the base of aquatic food webs. In recent years, chemical communication between diatoms and associated bacteria has emerged as a key factor

Application of a Diatom Transfer Function to Quantitative Paleoclimatic Reconstruction — A Case Study of Yunlong Lake, Southwest China

open access: yesFrontiers in Earth Science, 2021
Although diatom records from lake sediments have been used for quantitative paleoclimatic reconstruction, their validity and sensitivity have rarely been tested rigorously.

Evolution and regulation of nitrogen flux through compartmentalized metabolic networks in a marine diatom

open access: yesNature Communications, 2019
Diatoms outcompete other phytoplankton for nitrate, yet little is known about the mechanisms underpinning this ability. Genomes and genome-enabled studies have shown that diatoms possess unique features of nitrogen metabolism however, the implications ...

Climate variability in SE Europe since 1450 AD based on a varved sediment record from Etoliko Lagoon (Western Greece) [PDF]

open access: yes, 2017
To achieve deeper understanding of climate variability during the last millennium in SE Europe, we report new sedimentological and paleoecological data from Etoliko Lagoon, Western Greece.

Survival of fossils under extreme shocks induced by hypervelocity impacts [PDF]

open access: yes, 2014
Experimental data are shown for survival of fossilized diatoms undergoing shocks in the GPa range. The results were obtained from hypervelocity impact experiments which fired fossilized diatoms frozen in ice into water targets.

Diatom Molecular Research Comes of Age: Model Species for Studying Phytoplankton Biology and Diversity[OPEN]

open access: yesThe Plant Cell, 2019
Diatoms, the world’s most diverse group of algae, are emerging as important model systems for studying eukaryotic phytoplankton biology and evolution. Diatoms are the world’s most diverse group of algae, comprising at least 100,000 species. Contributing ∼

Benthic diatoms and some environmental conditions in three lowland streams [PDF]

open access: yes, 2002
This article reports on the ecological preferences of benthic diatoms in relation to pH, conductivity and organic pollution-eutrophication and their tolerance spectrums. Three Pampean streams subjected to different human impacts were studied.
