hello
to all or any practitioners of micropropagation:
How crucial is microprogation in gaining a production advantage over 'traditional' growers? I suppose this varies between different plant groups, so do you know of any particulars?
What micropropagation textbooks did you find most helpful? Do you know of any short courses on micropropagation in the UK or elsewhere (in case I must fulfil prerequisites - I'm a bio phd with extensive sterile culture experience)?
Are there any general use plant tissue culture media that can be formulated from easy-to-obtain ingredients? And to what extent are species-specific protocols openly published (e.g. in the Journal of MP) versus being kept closely guarded trade secrets?

hmm... I could keep typing questions on this newly engrossing subject all night... anyone want to be my micropropagation mentor?

any info greatly appreciated, thanks
