Additional file 1:

Accession numbers of the sequences encoding proteins similar to ST proteins. Sequences were obtained after different searches in EMBL databases as indicated in Methods. Full-length ORFs of chickpea CarST1 and CarST2 nucleotides sequences were used as well as the nucleotide sequences of their conserved repeats.

ST deduced amino acid sequences organized by repeats and sorted by alphabetical order of the plant species. The signal peptide is highlighted in grey; the first repeat is highlighted in green (except when it was chosen for the alignment); in blue, the repeats used for the analysis of alignment; in yellow, the Tyr in the repeats; in dark green, the putative phase shift. Red letters indicated Tyr, Trp and Cys in the mature N-terminal end before the repeats; pink letters indicated undefined amino acids. The putative N-glycosilation sites appeared underlined. The number of amino acids in the repeats refers to the most frequent one.
