| Abstract |
Agave L. is a genus of economic importance, and many of the 166 species in the American plant genus Agave L. inhabit high-stress environments, which makes the genus promising for facing global climate change. However, sustainable use of economically important species without interfering with their ecology and evolution requires generating knowledge about the factors responsible for their genetic variation and diversity and, on this basis, their adaptation and speciation. Few genetic studies exploring the evolutionary relationships, speciation processes, genetic variability and diversity within species of Agave are currently available. Analyses of rDNA loci have been performed with the purpose of determining the genetic variability and diversity of the genus Agave, and these loci have been used as genetic markers of ploidy. However, the factors involved in the diversity of 5S rDNA regions in Agave have not yet been studied in depth. Our study explored the possible mechanisms of genetic (retroelements) and epigenetic (DNA methylation) diversity in 5S rDNA regions in Agave. We characterized the 5S rDNA gene tandem in species of the genus with different ploidy numbers and determined the levels of methylation in 13 haplotypes of 5S rDNA and in four non-transcribed spacers (NTS). Our results showed highly dynamic methylation with a high percentage in haplotypes and NTS of 5S rDNA regions in Agave. The characterization of the 5S rDNA tandem array in Agave revealed vestigial remains of the Cassandra terminal-repeat retrotransposon in miniature (TRIM). Our analysis supported previous results suggesting that in species of Agave L., regulation and diversity of 5S rDNA regions are controlled by coordinated genetic and epigenetic events, which will vary according to the species and the level of ploidy. The artificial pressure to which some agave crops are subjected may affect the mechanisms of evolution of gene 5S rDNA. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 11 July 2018.
All research outputs
#17,982,872
of 23,094,276 outputs
Outputs from Journal of Molecular Evolution
#1,248
of 1,455 outputs
Outputs of similar age
#235,742
of 326,353 outputs
Outputs of similar age from Journal of Molecular Evolution
#10
of 12 outputs
Altmetric has tracked 23,094,276 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,455 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 12th percentile – i.e., 12% 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 326,353 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 12 others from the same source and published within six weeks on either side of this one. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
