| Outline of Annual Research Achievements |
We are planning to investigate how methylation variation is distributed among individuals from different habitats in different level of stress, and how this variation is correlated with their morphological differences and gene expression.
In order to do this we first sequenced the genomes and transcriptomes of representative mangrove species using the combination of long read sequencing technology (pacbio) supplemented by the more conventional platforms (Illumina Hiseq and matepair) to correct for the error of long read sequencing. To produce a high-quality reference genome, we performed a de novo assembly using these sequencing data.
We have also started a de novo RNA seq analysis and complementary detailed de novo annotation of genes based on RNA sequencing data.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The genome assembly and annotation process has been completed as planned. We also completed gene expression analysis to identify genomic characteristics that are conserved within each group of plants but differ among them and now trying to reveal differences in the transcriptome profiles among populations that are growing under different level of stress.
|
| Strategy for Future Research Activity |
We will try to integrate epigenome data, and understand impact of environmental changes on epigenome dynamics in mangrove genome.
