Description
Phytoplankton cells span a large size range, from picoplankton (<2µm), nanoplankton (2 to 20µm), microplankton (20 to 200µm) to macroplankton (200 to <2000µm). Cell size interacts with multiple selective pressures, including cellular metabolic rate, light absorption, nutrient uptake, cell nutrient quotas, trophic interactions and diffusional exchanges with the environment. Beyond simple size, cells of different shapes differ in surface area to volume ratio. For example, more elongated cells, such as pennate diatoms, have a larger surface area to volume ratio compared to more rounded cells, such as centric diatoms, of equivalent biovolume, which can in turn influence diffusional exchanges between cells and their environment. We assembled metadata on diverse marine phytoplankters, in parallel with genomic or transcriptomic data annotations to identify genes encoding enzymes, to facilitate analyses of genomic patterns of encoded enzymes across diverse taxa, sizes, growth forms and origins of strains.
Notes
In MetaData.csv, combinedHits.csv, MetaDataDictionary.csv and CombinedHitsDataDictionary.csv, missing values are left blank to facilitate direct import into a dataframe under 'R'.
.csv files are accessible through many software platforms including LibreOffice, but combinedHits.csv is large, so importing directly into 'R' is advisable.

contains the code used to generate:
Omar NM, Fleury K, Beardsall B, Prášil O, Campbell DA, 2022, Reactive Oxygen Species Production and Scavenging; Genomic Patterns Across Marine Phytoplankton, in review - `R/ROSDataImport.Rmd` imports data from the Snakemake pipeline, to generate CombinedHits.csv.
- `R/ROSModels.Rmd` imports CombinedHits.csv and MetaData.csv, and generates the Poisson and Quasi-Poisson models used in the manuscript.
- `R/ROSGenomicPatternsBySubstrate.Rmd` generates the manuscript.
