经genbank同源性比较，在10个表达差异的基因中有3个未发现与之明显同源的已知基因，为未知基因，另7个为已知基因。
Differential screening for the library revealed that , 167 of 237 clones randomly selected from the library are positive and represent genes that were exclusively or intensively expressed in bract , which contain inserts ranging from 100 to 2000 bp in length . moreover , except a few clones were expressed predominantly in bract , absolute majority of subtraclive clones were expressed at low level in all checked organs , i . e . , bract , leaf and root
用地高辛标记的珙桐苞片、叶片和根的cdna做探针，与差减杂交所获得克隆的pcr产物的杂交结果表明，有少数基因在这些器官中都是大量表达，而大多数在这些器官里的表达量均很少，除苞片外，一般均检测不到，有部分基因在苞片中优势表达。
