1. Advantages in Transcript Structure Resolution?
Compared to short-read sequencing, third-generation full-length transcriptomics offers distinct advantages in resolving transcript structures:
It enables the direct sequencing of complete mRNA molecules without the need for de novo assembly of short fragments. This capability allows for the precise identification of alternative splicing events, fusion genes, and novel transcripts, effectively circumventing common issues associated with second-generation sequencing, such as assembly artifacts and incomplete structural reconstruction. Furthermore, it accurately distinguishes between highly homologous isoforms, providing authentic and comprehensive sequence information essential for transcript annotation and regulatory analysis.
2. Role in Functional Genomics of Non-Model Species?
In the functional genomic study of non-model species, third-generation full-length transcriptomics plays a pivotal role:
For species lacking a high-quality reference genome, this technology facilitates the direct construction of a comprehensive full-length transcript catalog. It enables accurate Coding Sequence (CDS) prediction, gene functional annotation, and the identification of non-coding RNAs. By bridging the gap of fragmented transcript information in de novo (reference-free) studies, it provides high-quality data support for downstream applications, including gene family analysis, molecular marker development, and research into stress resistance mechanisms.
