Cover figure. Transformation of Pelargonium sidoides using Agrobacterium rhizogenes. (A) Induction of hairy roots on explants. Root initials (RI) appearing on an explant together with callus (C); (B) C58C1-transformed roots. Note the presence of residual agrobacterial growth (AR); (C) Transgenic plantlets with prolific hairy roots. Regeneration of transgenic shoots occurred spontaneously; (D) A4T-transformed hairy roots with a typical non-gravitropic character; (E) Lateral root (LR) formation on a primary root (PR) with numerous root hairs (RHs); (F) Liquid culture of transgenic roots after a month in culture; (G) Transgenic roots were extensively branched, a typical characteristic of hairy roots; (H) Untransformed roots (Untr’) grew slowly compared to transformed root cultures such as the A4T-A clone after one month in culture; (I) Transgenic roots extracted from liquid culture showing unusual black root tips and formation of tubers (T). Please see article by Colling et al. on pages 561–572 in this issue.
