Isolation and Characterisation of Wheat cDNA Clones Encoding PR4 Proteins

Two cDNA clones encoding the previously characterised PR4 proteins wheatwin 1 and wheatwin2 from wheat (Triticum aestivum cv. S. Pastore) have been identified and named wPR4a and wPR4b, respectively. The clones have been isolated by screening a cDNA library with a specific cDNA probe obtained by RT-PCR. The wPR4a and wPR4b cDNAs contain open reading frames of 441 and 447 bp that encode for wheatwin1 and wheatwin2, respectively.
