Isoforms of nonspecific lipid-transfer protein 1 (nsLTP1) and nonspecific lipid-transfer protein 2 (nsLTP2) were investigated in bran tissues isolated from caryopses of two cereal crops quite relevant for the Italian market, the cultivar Centauro of soft wheat (Triticum aestivum) and Italian emmer or farro (Triticum dicoccon Schrank). By sequential separation of the bran extracts on cation-exchange and gel filtration chromatographies, fractions containing only proteins belonging to the nsLTP1 and nsLTP2 classes were obtained. The proteins were roughly identified by SDS-PAGE and by immunoreactions in Western blotting experiments. By MALDI-MS and RP-HPLC/ESI-MS analyses we were able to show the presence of several LTP1 and LTP2 isoforms in the investigated species. Bioinformatic searches based on the determined Mr indicated that (i) two nsLTP1s already identified in T. aestivum have Mr and number of Cys residues identical to that of a 9.6 kDa protein present both in soft wheat cv. Centauro and in farro; (ii) two isoforms of nsLTP2 detected in T. aestivum have the same Mr and number of Cys residues of two 7 kDa proteins found in Centauro; and (iii) a nsLTP1 detected in Ambrosia artemisiifolia has Mr and number of Cys residues coincident to that of a 9.9 kDa protein found both in soft wheat cv. Centauro and in farro.
