Summary The extent and type of chloroplast DNA restriction fragment length polymorphism was determined among individual tree samples of coast redwood, Douglas fir, incense-cedar, and loblolly pine. A total of 107 trees was surveyed for three restriction enzymes (BamHI, EcoRI, HindIII) and six chloroplast DNA probes from petunia (P3, P4, P6, P8, P10, S8). The probes comprise 64% of the petunia chloroplast genome. Polymorphisms were detected in all species but loblolly pine. Coast redwood and incense-cedar had a small number of rare variants, whereas Douglas fir had one highly polymorphic region of insertions/deletions in sequences revealed by the P6 probe from petunia. The mutation hotspot is currently being studied by DNA sequence analysis.
