I hope this helps :-)

Thank you very much for your suggestion.

Kind regards

My colleague Oula Ghannoum has published extensively in this field

Yes. Those are definitely more tolerent to water deficit than many of the C3 plants

Thank you,

Maybe, C3-C4 intermediate plants can better adapt in semi-arid environment and achieve high yields than to C4 species.
