In this experiment, the LC2 embryonic cell line of the cultivar Honghezi of longan (Dimocarpus longan Lour.) was used as materials for obtianing the synchronized embryogenic cultures of somatic embryogenesis at different developmental stages and further researches were as follows: ① analysing the specific proteins expressed during longan somatic embryogenesis by 2-DE; ② separating the low-molecular-weight (LMW) peptide expressed at the late-stage of somatic embryogenesis; ③ identifying the peptide by Peptid...
