I'm sorry, but as of my last knowledge update in January 2022, I don't have any information on "Dootsi" plant parts. It's possible that this term refers to a specific plant or concept that has emerged or become known after that date. If "Dootsi" is a term in a specific field or region, it may not be widely recognized in general sources.

If you have any additional details or if "Dootsi" refers to a particular plant or concept, please provide more information so I can better assist you. Otherwise, if it's a recent development or a term specific to a niche community, you might want to consult more recent sources or experts in that field for the latest information.
