| Abstract |
The sequence of a representative mitochondrial gene COXI, encoding cytochrome c oxidase subunit I, was determined in five species that cover all the orders of the Prymnesiophyta with the exception of the Pavlovales. Through this analysis, we noticed that the 'stop' codon UGA appears frequently and, specifically, at conserved tryptophan (Trp) sites of the gene. We showed these sites were not edited in the corresponding mRNA in one of these species, Isochrysis galbana. Therefore, it is most likely that the UGA codon is used for Trp, and not as a stop codon, in prymnesiophytes. All the analyzed prymnesiophytes made a tight cluster on the COXI phylogenetic tree which includes representative species of green-algae, land plants, yellow-green algae, eustigmatophytes and a red-alga. This suggests a monophyletic origin for the prymnesiophytes. The same deviant genetic code, i.e. UGA for Trp, has also been found in the red-alga, Chondrus crispus. In spite of the fact that this red-alga and the prymnesiophytes, share the same deviant genetic code for Trp, close affinity between the two groups was not statistically supported by the phylogenetic analysis of COXI sequences. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 October 2012.
All research outputs
#8,534,976
of 25,373,627 outputs
Outputs from Current Genetics
#345
of 1,232 outputs
Outputs of similar age
#9,366
of 28,974 outputs
Outputs of similar age from Current Genetics
#3
of 9 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,232 research outputs from this source. They receive a mean Attention Score of 3.3. This one is in the 38th percentile – i.e., 38% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 28,974 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 6 of them.
