Description Accepted date: 27 August 2020
Background: Mitogen Activated Protein Kinase (MAPK) cascade is a fundamental pathway in organisms for signal
transduction. Though it is well characterized in various plants, there is no systematic study of this cascade in tea.
Result: In this study, 5 genes of Mitogen Activated Protein Kinase Kinase (MKK) and 16 genes of Mitogen Activated
Protein Kinase (MPK) in Camellia sinensis were found through a genome-wide search taking Arabidopsis thaliana as
the reference genome. Also, phylogenetic relationships along with structural analysis which includes gene structure,
location as well as protein conserved motifs and domains, were systematically examined and further, predictions
were validated by the results. The plant species taken for comparative study clearly displayed segmental
duplication, which was a significant candidate for MAPK cascade expansion. Also, functional interaction was carried
out in C. sinensis based on the orthologous genes in Arabidopsis. The expression profiles linked to various stress
treatments revealed wide involvement of MAPK and MAPKK genes from Tea in response to various abiotic factors.
In addition, the expression of these genes was analysed in various tissues.
Conclusion: This study provides the targets for further comprehensive identification, functional study, and also
contributed for a better understanding of the MAPK cascade regulatory network in C. sinensis.
