Suppression of growth in excised FUS3 phosphomutant embryos. (A) Representative images showing growth (fus3-3) or suppression of growth of embryos on 0.4% agar for 5 d. Arabidopsis plants were grown under long days at 21 °C/18 °C, and embryos at 7 DAP were dissected from four siliques (n=100–200). Scale bar=1 mm. (B) Quantification of excised embryo growth. (C) Distribution of total developing seeds excised from four siliques (7 DAP). (D) Transcript levels of GA3ox2 measured by qPCR. GA3ox2 expression was only detected in fus3-3. All plants were grown under long days at 21 °C/18 °C and siliques were collected at ~10 DAP (walking stick/bent cotyledon stages). (This figure is available in colour at JXB online.)
