Abstract
In order to explore the effect of calcium on the SA-induced resistance to Botrytis cinerea in tomato(Solanum lycopersicum).Tomato Botrytis cinerea susceptible strain'L402'was pretreated with foliar spraying 8 mmol·L1 CaCl2 and 5 mmol·L-1EGTA,respectively.Then followed by application of exogenous 2 mmol·L-1 SA,3 d before B.cinerea infection.The disease index,ROS accumulation,variations of the activities of main resistance enzymes and their gene expression were analyzed.The results show that the disease index is significantly reduced by 37.27%compared to control in SA treatment 5 d after B.cinerea infection;While in Ca+SA treatment,the disease index reduced by 18%compared to SA treatment.Theproduction rate and H2O2 content reached the highest level at 1 d and 2 d,respectively,there is difference among treatments:production rate ofand H2O2 content in tomatoes treated by Ca+ SA are 33.05%and 29.31%higher than contro(lH2O),however,under EGTA+SA treatment significantly reduced by 32.62%and 46.34%,respectively.The peak of disease defense-related enzymes activity and gene expression also exist,difference obtained among treatments:PAL,chintase andβ-1,3-glucancse treated by Ca+SA are significantly higher than control,whereas EGTA and EGTA+SA significantly suppress PAL,chitinase,β-1,3-glucanase activity.These results indicate that Ca2 +plays a positive regulatory role in the SA-induced resistance to Botrytis cinerea in tomato,which is closely related to the PAL,chitinase,β-1,3-glucanase activity and gene expression.
