SSR marker analysis to determine the genetic variation in Solanum elaeagnifolium in Australia

Research output: Contribution to journalArticlepeer-review

Abstract

Silverleaf nightshade (Solanum elaeagnifolium Cav.) is a problematic summer-growing perennial weed in Australia. The genetic diversity of silverleaf nightshade is poorly understood. Nine silverleaf nightshade specific and 10 cross-species Simple Sequence Repeat (SSR) primer pairs were utilized to investigate the genetic variations among 94 silverleaf nightshade populations collected in Australia. High genetic diversity was found within silverleaf nightshade populations with an average genetic similarity at 0.43. The Unweighted Pair Group Method with Arithmetic mean based dendrogram indicated the presence of multiple genotypes of silverleaf nightshade in Australia and separated the 94 populations into two main groups. Our findings suggest the presence of genetically diverse silverleaf nightshade populations in Australia, which could contribute to the inconsistency in control efficacy between populations.
