Basic Information
CGSNL Gene Symbol SUG
Gene Symbol Synonym sug(su), su, sug1, su1, su-1
CGSNL Gene Name SUGARY ENDOSPERM
Gene Name Synonym sugary endosperm, sugary endosperm-1, sugary-1, sugary
Protein Name
Allele sugary-1
Chromosome No. 8
Explanation Endosperm is wrinkled but translucent and hard [597]. The inner part of starch layer is not stained by I-KI solution, but the outer part is stained weakly [440]. PO:0009089; endosperm. GRO:0007045; 09-mature grain stage. sugary in Nakamura et al. 1992. The starch mutant sugary contains reduced activities of isoamylase1 (ISA1) (Kawagoe et al. 2005).
