Figure 2

Multiple sequence alignment (MSA) of the N-terminal region of 30 representative LEA4 proteins showing the closest phylogenetical relation to AtLEA4-5 protein. Alignment visualization was performed by Jalview software. Residues were colored as follows: red: negatively charged residues; blue: positively charged residues; green: polar uncharged residues; pink; residues with hydrophobic side chain; magenta: glycine and proline; orange: tyrosine and phenylalanine, and yellow: cysteine. Colored asterisks represent the location of the amino acid residues modified in the mutants generated from AtLEA4-5. Black: LEA4-5-NT1; blue: LEA4-5-NT2; green: LEA4-5-NT3; yellow: LEA4-5-NT4; red: LEA4-5-NT9P. Motifs 1, 2 and 3 were considered according to Battaglia et al.4. The numbers in the upper part of the figure correspond to the AtLEA4-5 protein sequence. LEA4-5 protein from Arabidopsis is highlighted in a red box.
