Control of proliferation in the haploid meristem by CLE peptide signaling in Marchantia polymorpha
Fig 6
Genetic interaction of MpCLE1 and MpTDR. Mptdr knock-out mutant is insensitive to excess MpCLE1/TDIF.
(A and B) Overall morphology of 21-day-old plants grown from gemmae. (C) Area of thalli in 14-day-old plants (mean ± s.d.). No significant difference was found between Mptdr and Mptdr MpCLE1ox in Weltch’s t-test (p = 0.19, n = 17–18). (D-G) Overall morphology of 17-day-old plants grown from gemmae with or without 10 μM TDIF. (H-K) Archegonial receptacles. Mpcle1 and Mptdr indicate knock-out mutants. MpCLE1ox indicates MpEF1α promoter-driven overexpression. Note that MpCLE1 overexpression plants do not make gametangiophores (S3G Fig). Scale bars = 1 cm in (A,B,D-G) and 2 mm in (H-K).
