(a) white clover (T. repens); compared to (b) T. occidentale (c) prolific regeneration of shoots from an AZ4270 cotyledon following three weeks culture on 1C; (d) shoot regeneration under ammonium glufosinate selection following Agrobacterium-mediated transformation of cotyledon explants; (e) transient GUS expression on cotyledonary explants three days after inoculation with Agrobacterium broth; (f) GUS activity in a trifoliate leaf excised from stably transformed plants approximately eight weeks after transformation.
