Hello, PlantGENE forum,
I was wondering if anyone can point me toward sources for Rhizobium rhizogenes 
(Agrobacterium rhizogenes) for plant transformation? 
My location is at Cornell University in New York, USA, so an American source 
may be easiest.
Thank you,

P.S. This seems to be the first PlantGENE forum message, so fingers crossed 
that this goes well!
  

Re: Activate charcoal in plant tissue culture media

Hi Bill,

We have used activated when we had plant material that browned from phenolic 
type compounds that inhibited plant regeneration. We also used it for species 
that we had difficulty rooting. So, in these cases most likely an absorptive or 
neutralizing type of action.

I’m not familiar with the information you shared regarding its use to develop a 
desiccation medium.

Here is a link for a publication you might find helpful on the role of 
activated charcoal in plant tissue culture 
https://www.sciencedirect.com/science/article/pii/S0734975008000864?via%3Dihub

Best regards,

Subject: Activate charcoal in plant tissue culture media


Dear group,



What is the function of activated charcoal in plant tissue culture medium?

What is the mode of action?



Activated charcoal in medium puzzles me. Activated charcoal will chelate some 
elements in the medium.

Does this make the nutrients more easily available? Or bind them and prevent 
movement to the plant tissue?



In the paper Mukami et al. 2022 "Plant regeneration from leaf mesophyll derived 
protoplasts of cassava (Manihot esculenta Crantz)",

the authors describe a medium with the addition of 0.4 g/l activated charcoal 
as being a desiccation medium.

 Why might a small amount of activated charcoal added to a water-based medium 
be termed a desiccating medium?
