Hedyotis corymbosa
. (A) The complete sequence of EPSPS-S is shown. Differences
between the S type and R type are indicated below the S type sequence, and homological
regions are indicated by dots. (B) Comparison of the Pro178Ser sequence of EPSPS in three
grasses, showing conserved regions from
H. corymbosa
and Pro106Ser, Pro106Ala and/or
Pro106Thr of 3 grasses.
