Identification of single nucleotide polymorphisms (SNPs) at candidate genes involved in abiotic stress in two Prosopis species of hybrids

<p><em>Aim of the study</em>: Identify and compare SNPs on candidate genes related to abiotic stress in <em>Prosopis chilensis</em>, <em>Prosopis flexuosa</em> and interspecific hybrids</p><p><em>Area of the study: </em>Chaco árido, Argentina.</p><p><em> Material and Methods:</em> Fragments from 6 candidate genes were sequenced in 60 genotypes. DNA polymorphisms were analyzed.</p><p><em>Main Results</em>: The analysis revealed that the hybrids had the highest rate of polymorphism, followed by <em>P. flexuosa </em>and <em>P. chilensis</em>, the values found are comparable to other forest tree species.</p><p><em>Research highlights: </em>This approach will help to study genetic diversity variation on natural populations for assessing the effects of environmental changes.<em></em></p><p><strong>Keywords: </strong>SNPs; abiotic stress; interspecific variation; molecular markers.</p><p>
