Arabidopsis thaliana Ideal plant to study (like fruit flies for insects and mice for animals) Rapid reproduction takes 5- 6 weeks from seed germination to production of new crop of seeds Makes up to 10,00 seeds per plants Has one of smallest genomes Of 111,409, 949 DNA Base pairs very little of it is “junk”

Mechanosensitive Ion Channels Ion channels with gating altered by mechanical forces Ex. McSc opens “ in response to increased membrane tension” Basically opens up to let substances like salts out so cell doesn’t burst “Best understood” MS channels are in bacteria (like McSc)
