Nuclear microsatellite markers for population genetic studies in sugar maple (Acer saccharum Marsh.)
<p>A set of seven new nuclear microsatellite markers (nSSRs) was developed<br />for sugar maple (Acer saccharum Marsh.) using paired-end Illumina sequencing. Out of 96 primers screened in a panel of six unrelated individuals, seven markers amplified polymorphic products. The utility of t...
