From: Multiple morphogenic culture systems cause loss of resistance to cassava mosaic disease
Response of non-transgenic and transgenic cassava plants to inoculation with the infectious geminivirus clone EACMV-K201. Non-transgenic and transgenic plants of TMS 91/02324 and CMD3-type cultivar TMS 98/0505, respectively, were generated from FEC. a Percentage of cassava mosaic disease (CMD) symptomatic plants of FEC-derived and micropropagated TMS 91/02324. b Average CMD symptom severity scores (scale 0–5) on FEC-derived and micropropagated TMS 91/02324. c Percentage of CMD symptomatic plants of transgenic GFP expressing TMS 98/0505 and wild-type TMS 98/0505. d Average CMD symptom severity scores (scale 0–5) on GFP-expressing TMS 98/0505 and wild-type TMS 98/0505. Plant stems were cut back 48 days after biolistic inoculation and CMD assessed on new leaf growth. Breaks in the x axis indicate a lapse in shoot regrowth after stem cut-back
