Instructions for building the latest Mini-NFT hydroponics system for Marchantia. USB powered pod with self-contained media circulation and LED lighting. Based on GN1/6 kitchen vessel. Larger scale DIY hydroponic systems on the way. https://marchantia.org/mini-nft-hydroponics

Happy to share some of the auxin Marchantia research we've been working on for a while with @fromani.bsky.social and @jimhaseloff.bsky.social. We confirm long standing suspicions that stem cells in Marchantia exist in an auxin concentration/signalling minimum, and potentially a cytokinin maximum.

Marchantia stem cell maintenance and re-establishment are controlled by MpPIN1-mediated auxin transport and ARF signalling

Meristem organization in land plants depends on coordinated auxin distribution, transport and response, yet how these processes are integrated during vegetative growth of the gametophyte of non-seed p...
