Fig. 5. pgy1 enhances rev axillary meristem defects in Arabidopsis. (A) Wild-type flowering plant. (B) rev mutants lack axillary meristems at the base of some cauline leaves (arrows). (C) pgy1 rev plant with reduced stature compared with wild type and rev. Inflorescence forms few or no flowers. (D) SEM of pgy1 rev inflorescence. Most floral meristems either produce filamentous structures or fail to produce any organs. (E) rev phb phv/+ plant with reduced stature and inflorescence with few flowers. (F) SEM of rev phb phv/+ inflorescence. Most floral meristems produce filamentous structures similar to those in pgy1 rev. Scale bars: 200 µm in D,F.
