Population genetics of Walp. (Malvaceae) in the Hawaiian Islands.

Introduction: (Malvaceae) is the most widespread and variable taxon of Malvaceae in the Hawaiian Islands, growing with a diversity of morphological forms in different habitats including Midway Atoll, Nihoa, and all the main islands. Morphological variation exists within and among populations. The study aimed to investigate the genetic variation within and among populations from various habitats and geographic locations throughout the Hawaiian range of .

Phytobiomes are compositionally nested from the ground up.

Plant-associated microbes are critical players in host health, fitness and productivity. Despite microbes' importance in plants, seeds are mostly sterile, and most plant microbes are recruited from an environmental pool. Surprisingly little is known about the processes that govern how environmental microbes assemble on plants in nature.
