1.1.1.295 Oryza sativa Japonica Group early regulation of genes putatively related to rice root-knot nematode (RRKN) Meloidogyne graminicola damage-associated molecular pattern recognition (e.g. wall-associated receptor kinases), signalling (nucleotide-binding, leucine-rich repeat (NLRs)), pathogenesis-related (PR) genes (PR1, PR10a), defence-related genes (NB-ARC domain-containing genes), as well as a large number of genes involved in secondary metabolites including diterpenoid biosynthesis (CPS2, OsKSL4, OsKSL10, Oscyp71Z2, oryzalexin synthase, and momilactone A synthase) is observed in rice Meloidogyne graminicola-resistant mutant line-9. After the nematode juveniles penetrate the roots of line-9, early recognition of invading nematodes triggers plant immune responses mediated by phytoalexins, and other defence proteins such as PR proteins inhibit nematode growth and reproduction.

1.1.1.295 metabolism early regulation of genes putatively related to nematode damage-associated molecular pattern recognition (e.g. wall-associated receptor kinases), signalling (nucleotide-binding, leucine-rich repeat (NLRs)), pathogenesis-related (PR) genes (PR1, PR10a), defence-related genes (NB-ARC domain-containing genes), as well as a large number of genes involved in secondary metabolites including diterpenoid biosynthesis (CPS2, OsKSL4, OsKSL10, Oscyp71Z2, oryzalexin synthase, and momilactone A synthase) is observed in rice Meloidogyne graminicola-resistant mutant line-9. After the nematode juveniles penetrate the roots of line-9, early recognition of invading nematodes triggers plant immune responses mediated by phytoalexins, and other defence proteins such as PR proteins inhibit nematode growth and reproduction. Mechanisms underlying plant-nematode resistance in rice, overview. Momilactone A is one of several phytoalexins also such as oryzalexin D, oryzalexin E, and phytocassane being part of the secondary metabolite biosynthesis pathways activated in defense. The enzyme is involved in diterpenoid biosynthesis Oryza sativa Japonica Group
