• FLOURY SHRUNKEN ENDOSPERM1 connects phospholipid metabolism and amyloplast development in rice., 2018, Plant Physiol.

Genbank accession number

• Additionally, the total galactolipid content in developing fse1 endosperm was significantly reduced, which may cause abnormal amyloplast development
• Our results identify FSE1 as a phospholipase-like protein that controls the synthesis of galactolipids in rice endosperm, and provide a novel connection between lipid metabolism and starch synthesis in rice grains during endosperm development
• Map-based cloning showed that FSE1 encodes a phospholipase-like protein homologous to phosphatidic acid-preferring phospholipase A1

• FSE1, OsbZIP60, OsbZIP60-mediated unfolded protein response regulates grain chalkiness in rice., Furthermore, OsbZIP60 is found to activate the expression of key genes related to grain chalkiness, such as GPA3, FSE1, FLO7, Chalk5, OsNF-YB1, and OsPK2, whose expression is significantly suppressed in osbzip60 and overexpression lines of OsbZIP50, OsBiP1, OsBiP2, and OsBiP3
