Basic Information
CGSNL Gene Symbol RE1
Gene Symbol Synonym re1
Gene Name Synonym reduced embryo-1, REDUCED EMBRYO1
Protein Name
Allele re1, re1-1, re1-2
Chromosome No.
Explanation Significant development of endosperm results in the restriction of space for embryo development, embryo size being reduced to 35-45% of that of the wild type. Size of every organ in embryo is reduced. This gene controls the development of endosperm. [708] PO:0009009; embryo ; PO:0009089; endosperm. GRO:0007044; 06-heading stage ; GRO:0007042; 08-dough stage ; GRO:0007045; 09-mature grain stage ; GRO:0007046; 07-milk stage. GO:2000014: regulation of endosperm development. RE1 and RE2 act upstream of GE in embryo-facing endosperm and are epistatic to GE in endosperm, but non-epistatic in embryo. They have opposite roles to GE in embryo/endosperm size balance (Nagasawa et al. 2013).
