To investigate processes regulating the reinitiation of growth and differentiation during seed germination, we have studied the transcriptional activities of sets of genes that are expressed at specific stages of embryogeny and post-germination in the higher plant Brassica napus L. We show that transcripts from a subset of the genes are elongated in nuclei isolated from dry seeds, indicating that these genes are competent to be transcribed in desiccated and quiescent mature embryos. Analysis of… CONTINUE READING
