To explore poorly understood differences between primary and subsequent somatic embryogenic lines of plants, we induced secondary (2ry) and tertiary (3ry) lines from cotyledonary somatic embryos (SEs) of two Douglas-fir genotypes: SD4 and TD17. The 2ry lines exhibited significantly higher embryogenic potential (SE yields) than the 1ry lines initiated from zygotic embryos (SD4, 2155 vs 477, TD17, 240 vs 29 g(-1) f.w.). Moreover, we observed similar differences in yield between 2ry and 3ry lines of SD4 (2400 vs 3921 g(-1) f.w.). To elucidate reasons for differences in embryogenic potential induced by repetitive somatic embryogenesis we then compared 2ry vs 1ry and 2ry vs 3ry lines at histo-cytological (using LC-MS/MS) and proteomic levels.
