  • Title: Cell wall invertase as a regulator in determining sequential development of endosperm and embryo through glucose signaling early in seed development.
    Author: Wang L, Liao S, Ruan YL.
    Journal: Plant Signal Behav; 2013 Jan; 8(1):e22722. PubMed ID: 23221750.
    Abstract:
    Seed development depends on coordination among embryo, endosperm and seed coat. Endosperm undergoes nuclear division soon after fertilization, whereas embryo remains quiescent for a while. Such a developmental sequence is of great importance for proper seed development. However, the underlying mechanism remains unclear. Recent results on the cellular domain- and stage-specific expression of invertase genes in cotton and Arabidopsis revealed that cell wall invertase may positively and specifically regulate nuclear division of endosperm after fertilization, thereby playing a role in determining the sequential development of endosperm and embryo, probably through glucose signaling.
