Diversity of the eight cysteine motif in rice, arabidopsis and wheat nsLTP types. The consensus motif of each nsLTP type was deduced from the analysis of the matures sequences of the 52 rice nsLTPs, the 49 arabidopsis nsLTPs and the 156 wheat nsLTPs presented in Table 1, Table 2, and Additional file 2, respectively. AtLTPII.8 that appears to be more distantly related to other type II sequences (see the phylogenetic analysis) was excluded. The values allowing direct identification of the nsLTP type are grey boxed. ^a cysteine residue number 6 is missing in AtLTPII.10. ^b cysteine residue number 7 is missing in TaLTPVIa.5. ^c cysteine residue number 8 is missing in AtLTPI.1. ^d AtLTPII.10, OsLTPVI.1, OsLTPVI.2, OsLTPVI.4, and TaLTPVIa subfamily members harbor an extra cysteine residue. All type VI contain a Val 4 aa before Cys7 and a Met 10 aa before Cys7 allowing a distinction between type IV and type VI. ^e AtLTPII.6 harbors an extra cysteine residue. ^f TaLTPIVc.1 and TaLTPIVa subfamily members harbor an extra cysteine residue. ^g 12 amino acid residues were counted for the TaLTPIVd.1 that displays no CXC motif. ^h OsLTPVII.1 and TaLTPVIIa.1 subfamily members harbor an extra cysteine residue.
