Abstract:3-nucletide sequence modes were extracted from the mRNA sequences of glycerol-3-phosphate acyltransferases(GPAT)from different chill-resistance plants,squash(Cucurbita moschata),pea(Pisum sativum),cucumber(Cucumis sativus),Arabidopsis thaliana,redflow(Carthamus tinctorius),spinach(Spinacia oleracea)and figleaf gourd(Cucurbita ficifolia).The mRNA secondary structures of translation domains in the reported sequences were predicted using Zuker‘s prediction,respectively.
