a
: The classification was based on the Rice Transcription Factor Database version 2.1 (http://ricetfdb.bio.uni-potsdam.de/v2.1/)
b
: The ratio was calculated as the number of CDS-AE loci/total number of loci.
c
: Significances of difference were examined between the CDS-AE proportion for each gene family and all CDS encoding TF by the chi-squared test. High (Low) represents the cloning efficiency of a TF family was significantly higher (lower) than the collection efficiency for the entire TF.
