Basic Information
CGSNL Gene Symbol SHL1
Gene Symbol Synonym shl1, sh1
Gene Name Synonym shootless 1, shootless-1
Protein Name
Allele shl1-1, shl1-2, shl1-3
Chromosome No. 12
Explanation In embryogenesis, shoot apical meristem is not differentiated. Coleoptile and epiblast are lost. Scutellum and radicle are normal. Modifies the expression domain of homeobox gene OSH1. Phenotypes of the two alleles are the same. PO:0009009; embryo ; PO:0020144; apical meristem. GRO:0007044; 06-heading stage ; GRO:0007042; 08-dough stage ; GRO:0007045; 09-mature grain stage ; GRO:0007046; 07-milk stage.
