Basic Information
CGSNL Gene Symbol DU1
Gene Symbol Synonym du1
Gene Name Synonym dull endosperm1, dull endosperm 1, dull endosperm-1
Protein Name
Allele du-1
Chromosome No. 10
Explanation Endosperm is inbetween waxy and translucent. Unlike the floury character, the dull character is expressed only when the grains are completely dry.[20356] Lowers the amylose content in endosperm. I-KI reaction is dark blue. low amylose content mutant. PO:0020104; leaf sheath ; PO:0009047; stem ; PO:0020039; leaf lamina ; PO:0009049; inflorescence ; PO:0009005; root ; PO:0009089; endosperm. GRO:0007151; 6.1-flowering stage ; GRO:0007045; 09-mature grain stage. a pre-mRNA processing (Prp1) family protein.
