| Abstract: | Soybean (Glycine max) alcohol dehydrogenase (ADH) cDNAs were amplified invitro from total RNA by the polymerase chain reaction (PCR). The amplification strategy involved first strand cDNA synthesis from anaerobic cotyledon total RNA using an 18- thymidine primer.The second strand cDNA primer was a conserved sequence near the 5' end of known plant ADH transcripts.The PCR products were ligated into a plasmid vector and unique clones were isolated on the basis of size and restriction pattern.Sequence analysis revealed three distinct classes of soybean ADH cDNAs, all of which showed high homology to Adh genes from maize and peas.RNA blot hybridization analyses showed differential expression patterns for these genes. One gene, expressed constitutively in all seedling organs, was inducible by anaerobiosis, one gene was expressed only in anaerobic organs, and the third gene was expressed predominantly in anaerobic roots. |
