The effects of the WOX13 OG mutations on Arabidopsis thaliana development. (A) Diagram of the AtWOX13 protein of the wox13 line 193G10 and the wild type plants (WT). (B) Diagram of the AtWOX14 protein of the wox14 line pst13645 and the wild type plants (WT). Legends: WOX13MOG (pink), HD (orange)(C and D) Comparative primary root growth of mutant and wild type seedlings during the first 6 days of development. In (C), wild type WS ecotype (grey bar) and wox13 line 193G10 (dot bar). In (D), wild type No ecotype (black bar) and wox14 line pst13645 (white bar). (E) Floral transition of wox13 and WS plants after a long day period of 4 weeks.(F) Floral transition of wox14 and Nossen plants after a long day period of 4 weeks. (G to K) Root development of the wild type plant (G and H) compared to the wox14 line pst13645 (I to K) that overproduces adventitious roots. (M to P) Flower development of wox14 line pst13645 inflorescences that show partial sterility (M). Wild type (upper silique in N and O) and wox14 semi-sterile silique (lower siliques in N and P). (N and P) Pictures obtained after clearing. (Q to S) Pollen viability tests with Alexander staining. (Q) Wild type, (R) wox14 pollen. (S) dmc1/RNAi sterile mutant. (T to V). Mature flower development in wild type plants (T) and the wox14 line (U and V). (V) Picture after clearing. Scale bars: Q, V (= 100 μm), R, S (= 50 μm) and T, U (= 500 μm).
