Abstract

Two novel cell wall structural proteins of spring wheat (Triticum aestivum L. em Thell.), undergo rapid deposition in the cell wall matrix in a H2O2-dependent reaction after the elicitation of cultures with Fusarium graminearum (L.)-derived elicitor. The amino acid compositions of these proteins were remarkably similar and indicated that they were highly acidic (pl 3.8). These proteins contained 13-17% each of Gly, Glx and Ser with lesser amounts (6-8%) of Ala, Asx and Thr, and it has been suggested that they are known as glycine- and serine-rich proteins (GSRPs). SELDI-MS ionization spectra demonstrated that these proteins have low molecular masses of 8 590 and 4 292 Da. These results are discussed in relation to the possible role of these novel proteins in rapid, cell wall defensive reactions to pathogenic attack.
