Characterization of mitogen activated protein kinases (MAPKs) in the Curcuma longa expressed sequence tag database.

ABSTRACT: Mitogen activated protein kinase (MAPK) cascades are universal signal transduction modules that play crucial role in plant growth and development as well as biotic and abiotic stress responses. 20 and 17 MAPKs have been characterized in Arabidopsis and rice respectively, which are used for identification of the putative MAPKs in other higher plants. However, no MAPK gene sequences have yet been characterized for asexually reproducing plants. We describe the analysis of MAPK EST sequences from Curcuma longa (an asexually reproducible plant of great medicinal and economic significance). The four Curcuma MAPKs contains all 11 MAPK conserved domains and phosphorylation-activation motif, TEY. Phylogenetic analysis grouped them in the subgroup A and C as identified earlier for Arabidopsis. The C
