1. A microdroplet-based method for sequencing large polynucleotide templates, comprisinga) providing a template droplet library, wherein each droplet in said library having a single template polynucleotide, polymerase enzyme and deoxynucleotides in a microdroplet, wherein the polynucleotide is 10 kb or larger;
- b) providing a primer droplet library, wherein each droplet in said library having a set of barcoded primers having a sequence comprising sequence shared by all primers at the 5′
-end, followed by a primer specific base barcode sequence in the middle, a random sequence at the 3′
-end and a label;
c) merging each template droplet with a primer droplet to form a merged droplet;
d) amplifying the large polynucleotide templates by multiple displacement amplification (MDA) in each of said merged droplets to form amplified large polynucleotides, wherein the 5′
-end of each amplified large polynucleotide is labeled by a bar-coded primer;
e) breaking emulsion of said merged droplets to recover the amplified large polynucleotides;
f) processing said amplified large polynucleotides by shearing, repairing ends and ligating linkers for sequencing of each amplified large polynucleotide;
g) sequencing of said amplified large polynucleotides labeled by said bar-coded primers.

Abstract
Methods for sequencing single large DNA molecules by clonal multiple displacement amplification using barcoded primers. Sequences are binned based on barcode sequences and sequenced using a microdroplet-based method for sequencing large polynucleotide templates to enable assembly of haplotype-resolved complex genomes and metagenomes.
