Applications of Next-Generation Sequencing in Plants
Jingjing Jin, Limsoon Wong, Nam-Hai Chua
Plant metabolites are compounds synthesized by plants for essential functions,
such as growth and development (primary metabolites, such as lipid),
and specific functions, such as pollinator attraction and defense against
herbivores (secondary metabolites). Many of them are also used directly,
or as derivatives, to treat a wide range of diseases for humans.
There is thus much interest to study the biosynthesis of different
plant metabolites and improve their yield.
In this project, we apply next-generation sequencing techniques to
to investigate lipid and secondary metabolisms, as well as
to identify relevant DNA variations, in important crops.
- Reference-based genome assembly pipeline. The pipeline has good ability
to detect mis-assembled scaffolds, repeat scaffolds, etc. and properly
- Genome annotation pipeline. The pipeline has to annotate protein-coding
genes, small noncoding RNAs, long noncoding RNAs, etc.
- Comparative genome analysis pipeline. The pipeline has to identify
SNPs and other sites of variations in the input genomes.
- Gene expression analysis technique. The difficulties for this technique
include: 1/ It has to support wild-type vs mutant comparison. This extreme
small sample size renders most statistical approaches useless.
2/ It has to take into consideration tghe dependencies between
different metabolic pathways as metabolites are produced and
consumed in multiple pathways.
- Apply the above technologies to a few important crops.
