Biochemical Characterization of Allene Oxide Synthases from the Liverwort Marchantia Polymorpha and Green Microalgae Klebsormidium Flaccidum Provides Insight into the Evolutionary Divergence of the Plant CYP74 Family
Koeduka, Takao; Ishizaki, Kimitsune; Mwenda, Cynthia Mugo; Hori, Koichi; Sasaki-Sekimoto, Yuko; Ohta, Hiroyuki; Kohchi, Takayuki; Matsui, Kenji (Springer Berlin Heidelberg, 2015)Allene oxide synthase (AOS) and hydroperoxide lyase (HPL) mediate the formation of precursors of jasmonates and carbon-six volatiles, respectively. AOS and HPL utilize fatty acid hydroperoxides and belong to the plant ... -
E-2-hexenal promotes susceptibility to Pseudomonas syringae by activating jasmonic acid pathways in Arabidopsis
Scala, Alessandra; Mirabella, Rossana; Mugo, Cynthia; Matsui, Kenji; Haring, Michel A; Schuurink, Robert C (Frontiers in Plant Science, 2013-04)Green leaf volatiles (GLVs) are C6-molecules – alcohols, aldehydes, and esters – produced by plants upon herbivory or during pathogen infection. Exposure to this blend of volatiles induces defense-related responses in ... -
Establishment of an efficient screening system to isolate rice mutants deficient in green leaf volatile formation
Mugo, Cynthia; Matsui, Kenji; Kumamaru, Toshihiro (Taylor & Francis, 2011)Green leaf volatiles (GLVs) are involved in defense responses of plants against wide range of stresses. In order to investigate the ecological significances of GLVs in rice plants, we started screening of rice mutants that ... -
Glutathionylation and Reduction of Methacrolein in Tomato Plants Account for Its Absorption from the Vapor Phase
Muramoto, Shoko; Matsubara, Yayoi; Mwenda, Cynthia Mugo; Koeduka, Takao; Sakami, Takuya; Tani, Akira; Matsui, Kenji (American Society of Plant Biologists, 2015)A large portion of the volatile organic compounds emitted by plants are oxygenated to yield reactive carbonyl species, which have a big impact on atmospheric chemistry. Deposition to vegetation driven by the absorption of ... -
The importance of lipoxygenase control in the production of green leaf volatiles by lipase-dependent and independent pathways
Mugo, Cynthia; Matsui, Kenji (Frontiers in Plant Science, 2014)Green leaf volatiles (GLVs) are six-carbon volatile compounds. They are formed from fatty acids by a dioxygenation reaction catalyzed by lipoxygenase and a subsequent cleavage reaction catalyzed by hydroperoxide lyase. GLVs ... -
Spatial expression of the Arabidopsis hydroperoxide lyase gene is controlled differently from that of the allene oxide synthase gene
Mugo, Cynthia; Matsuki, Atsushi; Nishimura, Kohji; Koeduka, Takao; Matsui, Kenji (Taylor & Francis, 2014-12-13)The hydroperoxide lyase (HPL) pathway for six carbon (C6) volatiles and the allene oxide synthase (AOS) pathway for jasmonates (JAs) share the first part of the pathway. To avoid competition, a separate localization of ...
