What all analysis we can do after the Denovo assembly for Transcriptome sequencing data of a new species. As the transcriptome data is not published before. I can mention some such as..
1. Do a Pathway analysis using KEGG.
2. Do a GO Annotation.
3. Try OrthoVenn to plot graphs for protein orthologs.
4. Try a BGI-WEGO plot.
This might be a broad question. But your inputs can help lot of researchers who are new to the Genomics and can give some ideas. Even a small input from you can be helpful.
