A major advantage of RILs is that the descendents of any one RIL are genetically identical, hence "immortal" (ignoring mutation accumulation), allowing RILs to be marker-genotyped once and phenotyped repeatedly in multiple labs and experiments.
Whole-genome sequencing of mutation accumulation lines allowed the comprehensive identification of mutations and revealed what factors of molecular and genomic architecture affect the mutational process.
If these mitigating processes are weak enough, an increase of mutagenic substances in the environment could easily lead to a rate of mutation accumulation that might allow extinction within time frames that are frequently of interest to conservation biologists.
This results in reduced membrane permeability that severely limits intracellular drug accumulation, allowing the evolution and/or the acquisition of other resistance mechanisms including target mutations, enzymatic production, etc [13].
These results suggest that Hsp90 may allow mutation accumulation in the secondary or further downstream interactors, instead of its primary targets.
Mutation accumulation followed by genome-wide sequencing allows for the determination of any potential insertion/deletion bias at mono-, di-, and tri- microsatellites without the use of reporter loci.
Freezing the strain, for long term storage, at three different time points, F170, F270 and F470, allowed us to compare and visualize mutation accumulation over the generations.
This rescaling allows us to predict the rate of mutation accumulation from Muller's ratchet in selfing organisms by using a methodology established for asexual systems [ 6].
Traditionally, these parameters are estimated in mutation accumulation experiments where replicate lines are propagated in conditions that allow mutations to randomly accumulate without the purging effect of natural selection.
The most accurate estimates of the mutation rate and spectrum come from mutation accumulation (MA) studies, whereby replicate lines are taken through single-cell bottlenecks, allowing for the accumulation of all but the most deleterious mutations (Mukai 1964; Kibota and Lynch 1996; Halligan and Keightley 2009).
