Identification, isolation, expression analysis and molecular characterization of nine genes key to late embryogenesis in Loblolly pine

A basic understanding of the molecular events occurring during zygotic embryogenesis is required to fully understand how and why only a very small percentage of somatic embryos develop past the late embryogeny phase of embryogenesis. In this work, we have identified genes that have been demonstrate...
