Plant proline-rich proteins(PRPs) are putative cell wall proteins,which are usually associated with different abiotic and biotic stress conditions.A soybean mRNA sequence encoding a proline-rich protein(PRP) was cloned and designated as GmPRP from Jilin 32 immature embryo gene expression profiles using RT-PCR.The GmPRP consisted of an ORF with a length of 396 bp,and encoded 131 amino acids(13.79 kD) with an isoelectric point of 8.96.There was no intron in the DNA sequence of GmPRP.Except a repetitive prolin...
