Two LysM receptor molecules, CEBiP and OsCERK1, cooperatively regulate chitin elicitor signaling in rice

TL;DR: It is reported here that rice cells require a LysM receptor-like kinase, OsCERK1, in addition to CEBiP, for chitin signaling, and the results of a yeast two-hybrid assay indicated that both CE biP and OsCerK1 have the potential to form hetero- or homo-oligomers.
Journal ArticleDOI
Identification of a Biosynthetic Gene Cluster in Rice for Momilactones
Kazuhiro Shimura,Atsushi Okada,Kazunori Okada,Yusuke Jikumaru,Kwang-Wook Ko,Tomonobu Toyomasu,Takeshi Sassa,Morifumi Hasegawa,Osamu Kodama,Naoto Shibuya,Jinichiro Koga,Hideaki Nojiri,Hisakazu Yamane +12 more
TL;DR: Functional analysis by heterologous expression in Escherichia coli followed by enzyme assays demonstrated that the AK103462 protein catalyzes the conversion of 3β-hydroxy-9βH-pimara-7,15-dien-19,6β-olide into momilactone A, providing strong evidence for the presence on chromosome 4 of a gene cluster involved in momILactone biosynthesis.
Journal ArticleDOI
WRKY76 is a rice transcriptional repressor playing opposite roles in blast disease resistance and cold stress tolerance
Naoki Yokotani,Yuko Sato,Shigeru Tanabe,Tetsuya Chujo,Takafumi Shimizu,Kazunori Okada,Hisakazu Yamane,Masaki Shimono,Shoji Sugano,Hiroshi Takatsuji,Hisatoshi Kaku,Eiichi Minami,Yoko Nishizawa +12 more
TL;DR: It is suggested that OsWRKY76 plays dual and opposing roles in blast disease resistance and cold tolerance, as well as the increased expression of abiotic stress-associated genes such as peroxidase and lipid metabolism genes.
Journal ArticleDOI
Five geranylgeranyl diphosphate synthases expressed in different organs are localized into three subcellular compartments in Arabidopsis.
TL;DR: RNA-blot and promoter-beta-glucuronidase (GUS) analysis showed that these GGPP synthases genes are organ-specifically expressed in Arabidopsis, suggesting there will be specific pathways of GGPP production in each organelle.
Journal ArticleDOI
Biosynthesis, elicitation and roles of monocot terpenoid phytoalexins
Eric A. Schmelz,Alisa Huffaker,James Sims,Shawn A. Christensen,Xuan Lu,Kazunori Okada,Reuben J. Peters +6 more
TL;DR: Recent advances in the discovery, biosynthesis, elicitation and functional characterization of monocot terpenoid phytoalexins are discussed, including conclusive evidence now exists for multiple plant receptors of fungal-derived chitin elicitors, phosphorylation of membrane-associated signaling complexes, activation of mitogen-activated protein kinase, involvement of phytohormone signals, and the existence of transcription factors.
