| Abstract |
The tobacco cultivar Nicotiana tabacum is a natural amphidiploid that is thought to be derived from ancestors of Nicotiana sylvestris and Nicotiana tomentosiformis. To compare these chloroplast genomes, DNA was prepared from isolated chloroplasts from green leaves of N. sylvestris and N. tomentosiformis, and subjected to whole-genome shotgun sequencing. The N. sylvestris chloroplast genome comprises of 155,941 bp and shows identical gene organization with that of N. tabacum, except one ORF. Detailed comparison revealed only seven different sites between N. tabacum and N. sylvestris; three in introns, two in spacer regions and two in coding regions. The chloroplast DNA of N. tomentosiformis is 155,745 bp long and possesses also identical gene organization with that of N. tabacum, except four ORFs and one pseudogene. However, 1,194 sites differ between these two species. Compared with N. tabacum, the nucleotide substitution in the inverted repeat was much lower than that in the single-copy region. The present work confirms that the chloroplast genome from N. tabacum was derived from an ancestor of N. sylvestris, and suggests that the rate of nucleotide substitution of the chloroplast genomes from N. tabacum and N. sylvestris is very low. |

Attention Score in Context
This research output has an Altmetric Attention Score of 9. 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 22 July 2021.
All research outputs
#3,873,876
of 25,837,817 outputs
Outputs from Molecular Genetics and Genomics
#120
of 3,366 outputs
Outputs of similar age
#13,228
of 174,011 outputs
Outputs of similar age from Molecular Genetics and Genomics
#2
of 7 outputs
Altmetric has tracked 25,837,817 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,366 research outputs from this source. They receive a mean Attention Score of 4.0. This one has done particularly well, scoring higher than 91% 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 174,011 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 89% of its contemporaries.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
