I tried to transform sweet potato with Agrobacterium rhizogenes almost
a month ago; still no hairy roots. Is there a "trick" to transforming spuds?
The agro was induced with coniferol, and the sterile potato pieces are on
B-5 medium plates.
p.s. no hairy roots from ginger either, inoculated
at the same time. Beets took ~2 weeks.
