Selected mutations for SSIIIa homoeologues.

Gene	Line	Codon	Protein coordinate and predicted effect	Chrom	Exon	Protein domain
SSIIIa-A	C2074	Cag → Tag	Q 531 (stop codon)	1A	3	Variable repeat region
SSIIIa-B	C0905	Caa → Taa	Q 1306 (stop codon)	1B	10	Catalytic domain
SSIIIa-D	C0291	Cga → Tga	R 435 (stop codon)	1D	3	Variable repeat region

Line is the mutant number in the TILLING population (e.g., C2074 = Cadenza 2074). Codon is the sequence of the control (left) and mutant (right) codons; the uppercase letter indicates which base was mutated. Protein coordinate includes the affected amino acid reside and the position based on deduced amino acid sequences from SSIIIa genomic DNA in the Cadenza cultivar. Chrom is the homoeologous chromosome. Protein domain is based on the defined proteins domains described in Li et al.⁸
