Six attenuated mutants, which combined 3′ NCR deletions and single or double REP substitution mutations were constructed to investigate cross protection effects on pepper plants.
Previous work on nondesensitizing AMPA receptor mutants, which combined crystallography, ultracentrifugation, and patch-clamp recording, showed that dimer formation by the ligand binding cores is required for activation of ion channel gating by agonists.
These were: mutant C+ targeting the clathrin-box motif site, mutant G targeting the "fourth site", and mutant C+G, which combined these two sets of mutations (Table 1).
Finally, high-throughput "next-generation sequencing" technologies are set to rapidly increase knowledge of the genome, epigenome, and transcriptome, which, combined with genetically engineered mouse mutants, will enhance insight into biological function.
The studio behind the latest revival of Teenage Mutant Ninja Turtles has apologised for a publicity poster which combined a picture of the heroes in a half shell hurtling from a burning building with the legend "September 11".
We are currently using this system in a 96-well format, which, combined with a commercial robotics preparation [ 19, 22], is capable of throughput levels required by a core feedstock testing facility for plant breeding and mutant screens.
From this screen we retrieved 20 unique gfp mutants, which were combined for further analysis with eight additional unique, uncharacterized gfp mutants recovered in a separate screen based on the same GFP reporter gene (Sasaki et al. 2012) (Table 1).
From a screen of approximately 280,000 M2 seedlings (approximately seven M2 progeny were tested from each M1 plant) (Haughn and Somerville 1990; Jander et al. 2003), we retrieved 20 unique gfp mutants, which were combined for further analysis with eight additional unique, uncharacterized gfp mutants identified in a separate screen based on the same GFP reporter gene (Sasaki et al. 2012).
Sickle hemoglobin (HgbS) occurs when a hydrophobic valine replaces a hydrophilic glutamic acid creating two mutant β-subunits which combine with two normal α-subunits.
Some combinations, such as the triple mutant I161V / F330Y / G368A which combines three mutations which decrease the catalytic efficiency of the enzyme, have a drastic effect on enzymatic activity (Fig. 1).
The set of offspring individuals Q g is generated by the following three different mutant strategies (i.e. DE/rand/best/1, DE/current-to-rand/1, and DE/rand/2) which combine the advantages of different mutant strategies to generate individuals in order to increase the maximum probability of generating better offspring into evolutionary population.
