Additive effects of multiple photoprotective mechanisms drive efficient photosynthesis under variable light conditions To cope with changing external conditions, plants undergo dynamic acclimation processes that remodel their photosynthetic machinery, optimizing energy use while minimizing damage to photosystems (PS)....

Dear #Physcomitrium community, why would you use BCDAT as an all-purpose growth medium?

It’s a great option for promoting protonema growth ahead of protoplast production. However, it might not be ideal to provide plants with 5 mM ammonium tartrate (AT) for other research applications #plantscience

Thanks! It’s a great set of tools, and given that they work in #Physcomitrium too, many of them can probably be translated to other moss species as well

Happy to present our cooperation with our friends in Helsinki:
