Hi, Rosaceae community,

I have a question regarding to the fruit structure terminology which are used in GDR database "genebank apple cDNA library" (http:// www.bioinfo.wsu.edu/gdr/projects/malus/unigeneV3/ malus_librarySummary.shtml). Please help me to define or clarify the following terms, I will add them either as new ontology terms or synonyms to the existing plant ontology based on your answers

fruit cortex -> is it the same as flesh or mesocarp? are these three terms used interchangeable? fruit core -> is this the tissue in the center of the fruit as seen in http://www.uq.edu.au/_School_Science_Lessons/5.6FruitPome.GIF? does it include seeds? what's the definition? Currently Plant Ontology database has "fruit placenta: a more or less localized region within a fruit to which seeds are attached", can "fruit placenta" be a synonym to "fruit core"?

Your opinion and comments are sincerely appreciated!

Thank you,
