I searche for information about possible mycorrhizal production of plant 
growth hormones  (auxins, gibberrelin, cytokins).

I am well awere of the role mycorrhiza play in suporting the trees (/plants) 
with mineral components from the soil. But someone once wrote about plant 
hormone production as well.  Do anyone have som information on this ??


Please give me info bye E.mail: Bjorn@ik.hist.no

Thank You!!

Most standard plant physiology texts will give you some basic information
on this- my dated copy of Salisbury & Ross, for example, explains that auxins,
as well as the cytokinins zeatin and zeatin riboside stimulate ectomycorrhizae
formation.  Plant hormone production by the fungal symbiont plays a role in
determining the degree of branching in a mycorrhizal root (increased branching
= more surface area for infection = greater transfer of nutrients, etc.)  If 
you need more info., there are many books on the general topic (and not a few
lurkers in this group that probably know a lot more about this).
