The chloroplast genomes of green algae are highly variable in their architecture. In this article we summarize gene content across newly obtained and published chloroplast genomes in Chlorophyceae, including new data from nine of species in Sphaeropleales (Chlorophyceae, Chlorophyta). We present genome architecture information, including genome synteny analysis across two groups of species. Als...

BACKGROUND AND OBJECTIVES Chlorophyceae are important constituents of marine phytoplankton. The taxonomy of Chlorophyceae was traditionally based solely on morphological characteristics. In the present research project, genetic diversity was investigated to analyze five species of Chlorophyceae from waters of the Persian Gulf. MATERIALS AND METHODS A clone library of the ribosomal small subun...

Haematococcus pluvialis is a freshwater unicellular green microalga belonging to the class Chlorophyceae and is of commercial interest for its ability to accumulate massive amounts of the red ketocarotenoid astaxanthin (3,3'-dihydroxy-β,β-carotene-4,4'-dione). Using confocal Raman microscopy and multivariate analysis, we demonstrate the ability to spectrally resolve resonance-enhanced Raman sig...

A manometric method for measuring photosynthesis in marine algae is described. Photosynthesis in the red alga Gigartina harveyana is shown to be similar in all important respects to photosynthesis in Chlorella and other Chlorophyceae.

Toxoplasma gondii is a zoonotic protozoa of economic significance in livestock. Infected livestock meat and products act as a source of T. gondii infection in humans. Current drugs against T. gondii are limited by hypersensitivity and toxicity, and are not effective against the encysted bradyzoite stage of T. gondii. Thus, there is urgent need for safe and effective therapeutic agents against T...

The mitochondrial gene for COXII is typically encoded in the organelle genome, however in some members of two unrelated groups, Apicomplexa and Chlorophyceae, cox2 is split into two genes, and both are encoded in the nucleus. Rare genomic changes (RGCs) have acquired popularity as phylogenetic markers, and accordingly this rearrangement of cox2 has been used to infer a possible source of the ap...

A method has been developed whereby the magnitude of a transient in O(2) uptake attributable to photosystem (PS) I activity, following single-turnover laser flashes of varying energy, can be used to measure the optical cross section of PSI. As measurements are made under the identical physiological conditions for which the cross section of PSII has previously been determined (AC Ley, DC Mauzera...
