(A) Northern blot analysis of total RNA (20 μg) from loblolly pine xylem, probed with 32P-labeled AEOMT cDNA. (B) Southern blot analysis of loblolly pine genomic DNA (50 μg per lane) digested with BamHI (lane B), HindIII (lane H), and SacI (lane S), probed with 32P-labeled AEOMT cDNA. One kb DNA ladder (GIBCO) was used as size markers, and values are given in kilobases.
