A regeneration and transformation protocol for ramie (Boehmeria nivea
Gaud.) is presented. Regeneration was obtained from leaf discs placed
on solid B-5 medium (Gamborg et al.1968) containing adequate concentra
tions of auxin and cytokinin. Co-cultivation of leaf discs with Agroba
cterium tumefaciens and subsequent regeneration resulted in transgenic
plants as shown by Southern blot and analysis of expression of the GU
S-marker gene.
