Abstract:

The studies on leave protein of Betula platyphylla seedlings by the methods of SDS-PAGE electrophoresis and dimensional gel electrophoresis was concerned. The result indicated that some new proteins such as 29kD pI4.3, 29kD pI4.2, 14kD pI5.3 and 11.5kD pI5.16 protein point were induced by soil drought stress, and some protein disappeared, for instance four protein between 12.4~11.5kD pI5.8~6.44 in seedlings leaves of B. platyphylla during soil drought stress.

Key words: Betula platyphylla seedlings, Drought stress, Protein component, SDS-PAGE electrophoresis, Two-dimensional gel electrophoresis
