ICBO_2018_21: From PO to GO and back


Our recent goal for the Plant Ontology (PO) is to have it integrated with then Gene Ontology (GO). The simplest aspect of this is to link morphological and anatomical images of structures in for PO terms with GO terms. This, also, would include images of in situs. By using a process of reciprocal illumination, we will be able to clarify and/or redefine PO terms, in particular. An example of this is the integument in the seed plants. Gymnosperms have one integument; whereas, Angiosperms (flowering plants) have two integuments, i.e., an inner integument surrounded by an outer integument. The question that arises is which of the two integuments in the Angiosperms is the equivalent of the single integument in then Gymnosperms? In Angiosperms, KANADI 1, 2 and 3 genes are expressed in the outer integument but not in the inner integument and in knock out mutants there is no outer integument. KANADI 1, 2 and 3 are found only in the Angiosperm outer integument. Thus, it appears that the inner integument of the Angiosperms is equivalent homologous) to the single integument of the Gymnosperms and the PO terms can be revised accordingly.
