Abstract

Abstract: To reveal the molecular mechanism of rice responding to lower phosphorus stress, the differential expression of proteins in the roots of allelopathic rice PI312777 was detected by the method of differential proteomics. Eleven proteins with obviously different abundance were producted by MALDI-TOF/MS. According to the function of proteins, those proteins were classified into three categories: In the first category, proteins were related to signal transduction-Cytochrome B5, Receptor-like kinase; In the second category, proteins were associated with plant growth-Putative chloroplast SPR receptor cpFtsY, Putative cdc2-like protein kinase cdc2MsC, Auxin transport protein, Proline-rich protein family-like; In the third category, proteins were related to allelochemical metabolism-Putative salicylic acid carboxyl methltransferase, Putative 4-coumarate-CoA ligase, Putative cytochrome P450, Phenylalanine ammonia-lyase, Putative squalene monooxygenase. In addition, the eleven proteins were all up-regulated with the exception of Cytochrome B5 and Putative squalene monooxygenase.
