Plant physiology meets phytopathology: plant primary metabolism and plant-pathogen interactions.
A summary of recent advances in the mutual interrelation between primary metabolism and pathogen infection is given to indicate current developments in non-invasive techniques and important strategies of combining modern molecular and physiological techniques with phytopathology for future investigations.

Based on the observed co-ordinated regulation of source/sink relations and defence responses by sugars and stress-related stimuli, the identified activation of distinct subsets of MAP kinases provides a mechanism for signal integration and distribution within such complex networks.

Computational analysis of sequenced rice genome revealed that their transcripts were differentially regulated in various stress and tissue-specific libraries, and conserved motifs in the deduced amino acid sequences of rice MAPKKKs strongly supported their identity as members of Raf, ZIK and MEKK subfamilies.

The strong activation of MAPKs and the fast and transient induction of Lin6 expresssion by the fungal elicitor resembles the effect of turanose, palatinose, and fluoro-Suc and indicates that non-metabolizable sugars are sensed as stress-related stimuli.
Mitogen-activated protein kinase signaling in plants under abiotic stress
In plants, MAP kinases are represented by multigene families and are involved in efficient transmission of specific stimuli and also involved in the regulation of the antioxidant defense system in response to stress signaling.

A Mitogen-Activated Protein Kinase Cascade Module, MKK3-MPK6 and MYC2, Is Involved in Blue Light-Mediated Seedling Development in Arabidopsis[C][W]
This work shows that the MKK3-MPK6 is activated by blue light in a MYC2-dependent manner during Arabidopsis seedling development and provides a revised mechanistic view of photomorphogenesis.
ROS mediated MAPK signaling in abiotic and biotic stress- striking similarities and differences
This review mainly focuses on the aspect of specificity of ROS mediated MAPK activation and how it differentiates with that of biotic stress in plants.
CrMPK3, a mitogen activated protein kinase from Catharanthus roseus and its possible role in stress induced biosynthesis of monoterpenoid indole alkaloids
Results from this study suggest a possible involvement of CrMPK3 in abiotic stress signal transduction towards regulation of transcripts of key MIA biosynthetic pathway genes, regulators and accumulation of major MIAs.
Cloning, characterization and localization of a novel basic peroxidase gene from Catharanthus roseus
It is proposed that CrPrx is involved in cell wall synthesis, and also that the gene is induced under methyl jasmonate treatment, and its potential involvement in the terpenoid indole alkaloid biosynthetic pathway is discussed.
