Tobacco MAP Kinase: A Possible Mediator in Wound Signal Transduction Pathways
Results indicate that this MAP kinase is part of the initial response of higher plants to mechanical wounding, and the levels of salicylic acid and transcripts for pathogen-inducible, acidic pathogenesis-related proteins were increased upon wounding.
Induction of Hypersensitive Cell Death by Hydrogen Peroxide Produced through Polyamine Degradation in Tobacco Plants1
Results indicate that one of the biochemical events in the HR is production of polyamines, whose degradation induces hydrogen peroxide, eventually resulting in hypersensitive cell death.
Polyamine Oxidase Is One of the Key Elements for Oxidative Burst to Induce Programmed Cell Death in Tobacco Cultured Cells1
It is suggested that polyamine oxidase is a key element for the oxidative burst, which is essential for induction of programmed cell death, and that mitogen-activated protein kinase is one of the factors that mediate this pathway.
The Crystal Structure of the Novel Calcium-binding Protein AtCBL2 from Arabidopsis thaliana*
Both a possible site and a possible mechanism for the target binding to AtCBL2 are discussed based on the three-dimensional structure, similar in overall folding topology to the structures of calcineurin B and neuronal calcium sensor 1, but differs significantly in local conformation.
Molecular Cloning and Functional Characterization of Three Distinct N-Methyltransferases Involved in the Caffeine Biosynthetic Pathway in Coffee Plants1
The results suggest that the presently identified threeN-methyltransferases participate in caffeine biosynthesis in coffee plants and substantiate the proposed caffeine biosynthetic pathway.
Jasmonate-Based Wound Signal Transduction Requires Activation of WIPK, a Tobacco Mitogen-Activated Protein Kinase
It is demonstrated that activation of WIPK is required for triggering the jasmonate-mediated signal transduction cascade that occurs when wild-type tobacco plants are wounded and subsequently causes an increase in jasMonate synthesis.
Periodic DNA Methylation in Maize Nucleosomes and Demethylation by Environmental Stress*
When maize seedlings were exposed to cold stress, a genome-wide demethylation occurred in root tissues, and one particular fragment, designated ZmMI1, contained part of the coding region of a putative protein and part of a retrotransposon-like sequence.
Caffeine and related purine alkaloids: biosynthesis, catabolism, function and genetic engineering.
Information is presented on metabolic engineering that has produced coffee seedlings with reduced caffeine content, and transgenic caffeine-producing tobacco plants with enhanced disease resistance and evidence for the involvement of caffeine in chemical defense and allelopathy is discussed.
Rapid systemic accumulation of transcripts encoding a tobacco WRKY transcription factor upon wounding
The results indicate that WIZZ is a new transcription factor which participates in early stages of the wound response, and specifically binds to sequences containing two TTGAC core motifs that are separated by a spacer of appropriate length.
Identification of isoprenoid quinones by frit-FAB liquid chromatography–mass spectrometry for the chemotaxonomy of microorganisms.
Abstract An easy and highly sensitive analytical method for the identification of microbial isoprenoid quinones using Frit-FAB liquid chromatography–mass spectrometry was developed. The composition
