Oryza sativa Brittle Culm 1-like 6 modulates β-glucan levels in the endosperm cell wall.

ABSTRACT: The endosperm cell wall affects post-harvest grain quality by affecting the mechanical fragility and water absorption of the grain. Therefore, understanding the mechanism underlying endosperm cell wall synthesis is important for determining the growth and quality of cereals. However, the molecular machinery mediating endosperm cell wall biosynthesis is not well understood. In this study, we investigated the role of Oryza sativa Brittle Culm 1-like 6 (OsBC1L6), a member of the COBRA-like protein family, in cellulose synthesis in rice. OsBC1L6 mRNA was expressed in ripening seeds during endosperm enlargement. When OsBC1L6-RFP was expressed in Arabidopsis cell cultures, this fusion protein was transported to the plasma membrane. To investigate the target molecules of OsBC1L6, we analyzed the
