Background:

• Short-read sequencing has limitations in resolving complex genomes with abundant repetitive regions.
• Third-generation sequencing technologies, like PacBio, provide longer reads, overcoming these limitations.
• Grapevine genomes present challenges due to extensive repetitive sequences.

Purpose of the Study:

• To describe sample and library preparation for PacBio long-read sequencing.
• To enable comprehensive genomic analysis of grapevine.
• To leverage long-read sequencing for higher organisms with complex genomes.

Main Methods:

• PacBio single molecule, real-time (SMRT) sequencing technology.
• Utilizing zero-mode waveguides (ZMWs) for real-time nucleotide detection.
• Detailed protocols for grapevine sample and library preparation.

Main Results:

• Generation of long reads (up to 20 kilobases).
• Successful application of PacBio sequencing to grapevine DNA.
• Demonstration of real-time nucleotide sequencing via fluorescence detection.

Conclusions:

• PacBio long-read sequencing is a powerful tool for grapevine genome analysis.
• This method is particularly beneficial for navigating repetitive genomic regions.
