Regeneration after injury induces accumulation of actin-1 mRNA at the apical wound site: the role of the nucleus. Basal cell fragments with or without rhizoid were generated and cultured (in the absence of inhibitor) for 3 d after amputation before processing occurred, as described schematically in Figure 7. Experimental conditions are similar to the one described in Figure 1; abbreviations as in Figure 7. The 700-bp RT-PCR product corresponds to actin-1 mRNA and the 250-bp product to rbcS mRNA.
