a
Notes Y32F6B.3 was omitted since its Rho membership is uncertain and is restricted to nematodes.
b
RhoL was omitted since it lacks the Rho-specific insert and is restricted to insects.
c
Members are considered as “absent” when missing in genomic data and only “not found”
when missing in EST database.
