In regard to the evolutionary rate of legume plants, Lavin reported that Phaseolus and closely related genera have the fastest substitution rates at the matK locus, within Leguminosae [ 21].
The mitogenome is highly reduced in size and genetic content and exhibits the highest guanine cytosine skew of any known genome and the fastest substitution rate among all red algae.
In conclusion, the overall evolutionary pattern of L2, K2, and K3 (fastest substitution rate, unusual distribution of the nucleotide substitution among the different stem/loop regions, and few compensatory substitution) does not support their role as tRNAs.
The fastest rate class is C-T rich (80%), just as C-T transitions are the fastest substitution class while slower rate classes are much less biased in terms of nucleotide composition (Table 1).

We hypothesized that the selection pressure during the acute inflammation would likely be higher than during chronic infection and result in a faster substitution rate.
Favorable characteristics for development of agricultural activities were crucial factors in the fast substitution of the physiognomy of the Cerrado by agricultural crops and pastures.
However, the BSP model gives a more recent tMRCA and faster substitution rates than the other demographic models.
The molecular clock analyses give broadly similar results regardless of clock model and tree prior, with the exception of the BSP tree prior, which gives an intriguingly recent tMRCA, and faster substitution rates than the other analyses.
The extent to which HEGs have not invaded other metazoans may either be a lack of opportunity, or that most metazoans have faster substitution rates, which mean the more rapid degeneration of HEGs.
This split easily indicates that the LTRs with the faster substitution rates are those of a more recent insertion time, namely the ERVK2, ERVK7 and ERVK9 along the Human-Chimp branch.
Studies of intraspecific data from birds have generally yielded faster substitution rate estimates [23], [47], peaking at a rate of 0.95 subs/site/Myr for the mitochondrial hypervariable region 1 in Adélie penguins [48].
Write better and faster with AI suggestions while staying true to your unique style.
Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
