- Genbank accession number
- Key message
- Wild-type Pi21 appears to slow the plant’s defense responses, which may support optimization of defense mechanisms
- The resistant pi21 allele, which is found in some strains of japonica rice, could improve blast resistance of rice worldwide
- QTL analysis and mapping of pi21 , a recessive gene for field resistance to rice blast in Japanese upland rice
- Transcriptome Analysis Highlights Defense and Signaling Pathways Mediated by Rice pi21 Gene with Partial Resistance to Magnaporthe oryzae.
- The pi21 gene confers partial and durable resistance to Magnaporthe oryzae
- However, little is known regarding the molecular mechanisms of resistance mediated by the loss-of-function of Pi21
- This study highlights possible candidate genes that may serve a function in the partial rice blast resistance mediated by the loss-of-function of Pi21 and increase our understanding of the molecular mechanisms involved in partial resistance against M
- Connection
- OsHIPP28, Pi21, A small secreted protein, RsMf8HN, in Rhizoctonia solani triggers plant immune response, which interacts with rice OsHIPP28., We confirmed the occurrence of in vivo cross-interactions of RsMf8HN with a rice molecule, the heavy metal-associated isoprenylated plant protein OsHIPP28, which is a protein related to the disease susceptibility factor Pi21
