摘要：

The total complexity of one constituent soybean (Glycine max) genome is estimated to be 1.29 · 109 nucleotide pairs, as determined by analysis of the reassociation kinetics of sheared (0.47 kilobase) DNA. Single copy sequences are estimated to represent from 53 to 64% of the genome by analysis of hydroxyapatite binding of repetitive DNA as a function of fragment length. From 65 to 70% of these sungle copy sequences have a short period interspetion with 1.11-1.36 kilobase lengths alternating with 0.3-0.4 kilobase repetitive sequence elements. The repetitive sequences of soybean DNA are interspersed both among themselves and among single copy regions of the genome. © 1979.
