Numbers of genes studied in Arabidopsis included in this study and the numbers of their corresponding homologs in moss and wheat

Gene group	Arabidopsis	Wheat	Moss
PTS1	337 predicted as PTS1 3 non-canonical PTS1 (Catalase)†	185* (of 65 A. thaliana PTS1 genes)	108 (of 63 A. thaliana PTS1 genes)
Total number of homologs identified		1052 (of 85 A. thaliana PTS1 genes)	282 (of 146 A. thaliana PTS1 genes)
Number of homologs predicted to contain PTS1		228 (of 64 A. thaliana PTS1 genes)	100 (of 60 A. thaliana PTS1 genes)
		3 paralogs for 1 catalase	8 paralogs for 3 catalase
Antioxidant enzymes	51	94 (of 27 A. thaliana genes)	49 (of 26 A. thaliana genes)
PEX	22	46	27

*For 46 PTS1 proteins of Arabidopsis the corresponding homologs in wheat could not identified due to major differences in protein sequences in Gramene and phytozome databases as described in the Methods.

^†Catalase (CAT) genes are included in the antioxidant genes set but they also possess a non-canonical PTS1 which although functional deviates from the PTS1 consensus
