| Abstract |
During interspecific crosses between Chlamydomonas eugametos and Chlamydomonas moewusii, an optional group I intron of 955 base pairs (CeLSU.5) in the C. eugametos chloroplast large subunit rRNA gene undergoes a duplicative transposition event which is associated with frequent co-conversion of flanking cpDNA sequences. In the present study, we show that the basic protein of 218 amino acids encoded by CeLSU.5 could mediate the phenomenon of intron transposition, also called intron homing. We overexpressed the ORF specifying this protein in E. coli using expression vectors that contain a C. moewusii cpDNA sequence encompassing the intron homing site. The expression product was found to exhibit a double-strand DNA endonuclease activity that is specific for the homing site. This activity was detected in vivo by self-linearization of the expression plasmids. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. 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 15 April 2014.
All research outputs
#4,696,781
of 22,789,566 outputs
Outputs from Current Genetics
#121
of 1,203 outputs
Outputs of similar age
#4,404
of 59,442 outputs
Outputs of similar age from Current Genetics
#3
of 14 outputs
Altmetric has tracked 22,789,566 research outputs across all sources so far. Compared to these this one has done well and is in the 76th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,203 research outputs from this source. They receive a mean Attention Score of 3.3. This one has done well, scoring higher than 79% of its peers.
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 59,442 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 85% of its contemporaries.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
