Fig. 2. — Arabidopsis fruit inhibition regulates future flowering. (A) The presence of seed-containing fruit on an inflorescence inhibits the development of buds, which would form a higher-order inflorescence if allowed to develop. (B) Seed-containing fruit proximal to the bud cluster act to inhibit flower development, bringing about inflorescence arrest in Arabidopsis. (C) Removal of fruit proximal to the inflorescence meristem around the time of inflorescence arrest results in the extended opening of floral primordia present within the bud cluster, which would not otherwise develop.
