Hi Naveed,

The problem with non-model species or unannotated genomes is the difficulty to extract their exact location and hence predicting their exact structure, you can consider using genomic sequences of an established eudicot which is phylogenetically related to your species as reference genomic sequence for carrying out above said work.

You can try

I hope this helps.
