Dear Jeff,

I cannot remember any specific info regarding the use of albinos as an
indicator of mutation frequency. However, you might want to check out the
following ref regarding the use of embryo lethals in Arabidopsis to estimate
the number of equivalent genomes required for EMS screens of embryonic
mutations.

Subject: Question about number of genes leading to albinism

We are trying to estimate chemically-induced mutation rates in a 
diploid wheat based on the frequency of albinos. Has anyone made an 
estimate of the number of genes which, if mutant, could produce this 
phenotype in Arabidopsis? Leads to likely people to talk to, 
references, and/or estimates all welcomed!

Thanks,
