Hello,

Is there an implementation of a C4 photosynthesis model in the OpenAlea project similar to the “Farquhar Wheat” model ( [farquhar-wheat/farquharwheat at 62bd7bf117de613f25d1367a10ab528c46903f14 · openalea-incubator/farquhar-wheat · GitHub](https://github.com/openalea-incubator/farquhar-wheat/tree/62bd7bf117de613f25d1367a10ab528c46903f14/farquharwheat) )? I was looking around the Adel-maize code to see where photosynthesis was implemented and didn’t see it. I apologize if I am missing something obvious!

The Farquhar Wheat model is really fantastic, by the way!

Thank you very much for your help,

Mary
