Draft genome assembly and sequencing dataset of the marine diatom Skeletonema cf. costatum RCC75

Data in Brief, 2022
Diatoms (Bacillariophyceae) are a major constituent of the phytoplankton and have a universally recognized ecological importance. Between 1,000 and 1,300 diatom genera have been described in the literature, but only 10 nuclear genomes have been published

High light stress under phosphorus limitation in summer may accelerate diatom shift from Skeletonema to Chaetoceros in an oligotrophic coastal area of Japan

Frontiers in Marine Science, 2023
In the Seto Inland Sea, the largest semi-enclosed sea in Japan, the most dominant diatom in the past, Skeletonema spp., has been replaced by another diatom Chaetoceros spp.

Nitrate Utilization by the Diatom Skeletonema costatum [PDF]

Plant Physiology, 1978
Nitrate uptake has been studied in nitrogen-deficient cells of the marine diatom Skeletonema costatum. When these cells are incubated in the presence of nitrate, this ion is quickly taken up from the medium, and nitrite is excreted by the cells.

Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling. [PDF]

Mol Ecol Resour
ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed biodiversity monitoring across taxa from bacteria to mammals, yet sample collection remains a major bottleneck. Passive sampling via adsorption and entrapment has emerged as a promising alternative to overcome the limitations of conventional active filtration.

Chlorophyll Turnover in Skeletonema costatum, a Marine Plankton Diatom [PDF]

Plant Physiology, 1979
[(3)H]- and delta-[(14)C]Aminolevulinic acids were incorporated into the chlorophylls of Skeletonema costatum, a marine plankton diatom. In the stationary phase of growth, the tetrapyrrole-based pigments reached steady-state labeling after 10 hours. Under conditions of exponential cell division and chlorophyll accumulation, (3)H was rapidly lost from ...

Shifts in Diatom Dominance Associated with Seasonal Changes in an Estuarine-Mangrove Phytoplankton Community

Journal of Marine Science and Engineering, 2020
A study on seasonal phytoplankton abundance and composition in a mangrove estuary, Matang Mangrove Forest Reserve (MMFR), Malaysia, was carried out to determine the phytoplankton structure in this ecosystem, and to identify potential indicators of ...

Chloroplast Genomes for Five Skeletonema Species: Comparative and Phylogenetic Analysis

Frontiers in Plant Science, 2021
Skeletonema species are cosmopolitan coastal diatoms that exhibit important roles in ecological system. The chloroplast genomes (cpDNAs) have been proven to be important in the study of molecular evolution and genetic diversity.

Morphological and Molecular Diversity of Phytoplankton in Beibu Gulf, Northern South China Sea. [PDF]

Ecol Evol
This study explored phytoplankton diversity and environmental drivers in Beibu Gulf based on morphology and metabarcoding. The findings reveal that morphology better reflected phytoplankton abundance while metabarcoding revealed the actual phytoplankton diversity.

Diatoms synthesize sterols by inclusion of animal and fungal genes in the plant pathway [PDF]

, 2020
Diatoms are ubiquitous microalgae that have developed remarkable metabolic plasticity and gene diversification. Here we report the first elucidation of the complete biosynthesis of sterols in the lineage.
