 Secrets on the Surface
Unexplained fish kills in a variety of Texas lakes, rivers, and hatcheries have been occurring since the middle-1980sÂ…recently these dilemmas have been traced to golden alga, which is a nearly invisible floating plant that uses small levels of salinity and ammonia to live.
This alga poses no threats to humans, livestock, or wildlife (similar to recent statements made about snakeheads), but it destroys the gills of gill-breathing creatures like fish, mussels, and clamsÂ…the key fish at risk in Texas so far have been largemouth bass, striped bass, shad, and trout.
One of the ironies involved with this complex organism is that the toxin it excretes to destroy gill cells is triggered by the lack of phosphorus in the water.

From a phylogenetic perspective, and compared to fungi, animals and plants, protists are by far the most diverse eukaryotic group, and the least well characterized at the level of the mitochondrial genome.
To date, we have completely sequenced the mitochondrial genomes of Prototheca wickerhamii (green alga), Porphyra purpurea (red alga), Rhodomonas salina (cryptomonad alga), Ochromonas danica (chrysophyte alga), Cafeteria roenbergensis (bicosoecid zooflagellate), Acanthamoeba castellanii (rhizopod amoeba) and Tetrahymena pyriformis (ciliate protozoon).
The sequencing of other mitochondrial genomes is in progress, including those of Pedinomonas minor (green alga); Reclinomonas americana, Malawimonas jakobiformis and Jakoba libera (jakobid flagellates); Chrysodidymus synuroideus (golden alga); and Thraustochytrium aureum (stramenopile).
