Basic Information
CGSNL Gene Symbol TGW6
Gene Symbol Synonym tgw6, OsSTRL7, STRL7
Gene Name Synonym total grain weight6, THOUSAND-GRAIN WEIGHT 6, STR-like 7
Allele TGW6(Kasalath), tgw6(Nipponbare), TGW6-Kasalath
Chromosome No. 6
Explanation TGW6 encodes a novel protein with indole-3-acetic acid (IAA)-glucose hydrolase activity. AB513135. The Kasalath allele contained six nucleotide substitutions and a 1-bp deletion at nucleotide 313 compared to the Nipponbare allele. Nipponbare TGW6 protein hydrolyzed IAA-glucose into IAA and glucose, but Kasalath TGW6 did not. (Ishimaru et al.)
