Genome

A draft genome of P. dactylifera (Khalas variety) was published in 2011 followed by more complete genome assemblies in 2013 and 2019. The later study used long-read sequencing technology. With the release of this improved genome assembly, the researchers were able to map genes for fruit color and sugar content. The NYU Abu Dhabi researchers had also re-sequenced the genomes of several date varieties to develop the first single nucleotide polymorphism map of the date palm genome in 2015.
