Macroscopic AR-response with/without 0.01 μM MeJA in IBA + Kin-cultured TCLs from JA-mutants. (a-h) Images under the stereomicroscope of the WT Ws (a-b), opr3 (c-d), dde2–2 (e-f), coi1–16 (g-h) TCLs at the end of the in vitro culture (day 15) in the absence (a, c, e, g) or in the presence of 0.01 μM MeJA (b, d, f, h). (a) TCL with elongated ARs (arrows) and callus. (b) TCL with a production of ARs higher than in (a). (c) TCL with callus with ARPs (arrows) and elongating ARs. (d) Detail of a TCL portion showing numerous ARPs. (e) TCL producing fewer ARs than in (f). (g-h) Similar ARP/AR production in TCLs cultured either without (g) or with (h) MeJA. (Images from the first replicate). Bars = 1 mm
