Abstract
The scutellum is the single cotyledon of grass embryos. The cells in direct contact with the endosperm form the scutellar epithelium which plays a major role in controlling the mobilization of the endosperm nutrient reserves. After imbibition, the epithelial cells elongate which leads to an increase in the contact area between the endosperm and the scutellum. We studied which factors regulate epithelial cell elongation. Elongation was inhibited by ABA and salicylic acid, basic and acid pH and high concentrations of sorbitol. Exogenous gibberellins stimulated elongation, but a reduction in gibberellin synthesis or perception did not inhibit it. Elongation was increased by sucrose, but not glucose. The application of transcription and translation inhibitors reduced elongation.
