Abstract: The protein components of seven embryogenic cultures were separated by SDS-PAGE during the early litchi somatic embryogenesis. The results showed that the protein components varied obviously during various stages of early somatic embryogenesis of litchi. Three low molecular weight proteins(6.13 kD、5.08 kD and 4.02 kD) emerged at the early developmental stages of somatic embryogenesis, which maybe played an important role in the process of the early somatic embryogenesis.
