Diatom blooms are important features of productive marine ecosystems and are known to support higher trophic levels. However, when stressed or wounded, diatoms can produce oxylipin molecules known to inhibit the reproduction and development of copepods and decrease microzooplankton growth rates. Using oxylipin chemical treatments, lipidomic analysis and functional genomic approaches, we provide evidence that nitric oxide (NO) and oxylipin signalling pathways in diatoms respond to protist…

A phenotype-genotype codon model for detecting adaptive evolution.
Related Articles A phenotype-genotype codon model for detecting adaptive evolution. Syst Biol. 2019 Nov 15;: Authors: Jones CT, Youssef N, Susko E, Bielawski JP Abstract A central objective in biology is to link adaptive evolution in a gene to structural and/or functional phenotypic novelties. Yet most analytic methods make inferences mainly from either phenotypic data …

Genome-wide Transcriptional Analysis of Tetrahymena thermophila Response to Exogenous Cholesterol
The ciliate Tetrahymena thermophila does not require sterols for growth and synthesizes pentacyclic triterpenoid alcohols, mainly tetrahymanol, as sterol surrogates. However, when sterols are present in the environment, T. thermophila efficiently incorporates and modifies them. These modifications consist of desaturation reactions at positions C5(6), C7(8), and C22(23), and de-ethylation at C24 of 29-carbon sterols (i.e. phytosterols). Three out of four of the enzymes involved in the sterol…
