Exogenous NO and H2O2 Dependent Signal Molecule Ca2+/CaMto EnhanceAnthocyanin Accumulation of Potato Tuber
Taking different colors potatos(Solanum tuberosum L.) ‘ Longshu No.8',‘ LongshuNo.7',‘ LC310-2'and ‘Shandongcairou' as materials,this experiment studied on anthocyanin accumulation and related signal mater Ca2 +-ATPase and CaM of potato tuber after treatment of water (CK),NO,H2O2,NO + H2O2.The results showed that,the anthocyanin accumulated in 4 gene-types potatoes,Ca2+-ATPase activity increased,CaM content enhanced after exogenous NO and H2O2 treatments.The inductive effect was NO + H2O2 ＞ H2O2 ＞ NO ＞ CK.Moreover,anthocyanin accumulation was related with Ca2+-ATPase activity increasing and CaM content enhance,and its related index was 0.9194 and 0.8859.It indicated that NO and H2O2 had a certain role in promoting the potato anthocyanin synthesis,and intracellular Ca2+/CaM signal play signal transduction in NO and H2O2 inducing potato anthocyanin synthesis.
