Predicted amino acid sequences of the seven cotton Sus genes GaSus1-7 (accession no. GaSus1 , JQ995522; GaSus2 , JQ995523; GaSus3 , JQ995524; GaSus4 , JQ995525; GaSus5 , JQ995526; GaSus6 , JQ995527; GaSus7 , JQ995528). Sequence alignment analysis was performed using Multiple alignment program wrapped within the DNAMAN 6.0 software (http://www.lynnon.com/). Identical amino acids are shaded and gaps are indicated by dots. The conserved serine residue for phosphorylation by Ser/Thr protein kinase is showed by an arrowhead. The characteristic sucrose synthase domain (broken underline) and a glycosyl transferases domain (single underline) were identified by the Interproscan algorithm (http://www.ebi.ac.uk/Tools/pfa/iprscan/). The extended C-terminal region of GaSus7 is shown by double underlines.
