Protease treatment of the plasma membranes could abolish the binding but NaIO_4 and glycosidase could not, indicating that nsLTP144 bound to plasma membranes protein without carbohydrate moiety. Using the homobifunctional cross-linking regent bissuberate (BS~3) and rice plasma membranes incubated with ~(125)I-Trx-nsLTP144, we identified, after SDS-polyacrylamide gel electrophoresis and autoradiography, a putative protein receptor on the rice plasma membranes with the molecular mass around 60 kDa. NsLTP144 can not trigger extracelluar alkalization in arabidopsis, but can abolish the extracellular alkalization effect of phytopathogen elicitor cryptogein, suggesting that cryptogein and nsLTP144 may bind to the same membrane protein. In vitro pull-down assay showed that nsLTP144 interacted with OsCaM1, a possible extracellular calmodulin, implying that nsLTP144 and OsCaM1 could function in the same signal transduction pathway. These results shed light on revealing the roles of nsLTP in vivo and make it promising to finally characterize the plasma membranes receptor of nsLTP.

Additionally, the growth of the pathogen was obviously affected by cultural media. The morphological characters such as colony color and diameter, and production of fruit body of the fungus growing on PDA, 10% V8, apple leaves dextrose agar and apple leaves extraction dextrose agar media were different. The fungus formed colonies of about 8mm in diameter and did not produce fruit bodies and aerial hyphae in 1 month incubation on PDA. However it formed the similar size colonies as on PDA and produced fruit bodies and aerial hyphae on 10% V8 and LDA media in the same incubation period. Very small colonies (2mm in diameter) and fruit bodies were found on LEDA media in the same incubation condition. These results indicated that successful isolation of M. coronaria from apple leaves depended on suitable isolation method and cultural media as well as fresh samples.
