ABSTRACT The study of the rules that govern relationship between phenotypic plasticity, genetic structure, and ecological success has traditionally focused on animals, plants, a few model microbial species, whereas non‐model microorganisms have received much less attention in this regard. floral nectar angiosperms is an ephemeral, island‐like habitat for different highly adapted yeasts bacteria. growth depends their ability to efficiently use available nutrients tolerate challenging physicochemical conditions, including high osmotic pressures, unbalanced carbon‐to‐nitrogen ratios, presence diverse defensive compounds plant origin. production alternative states response environmental cues (i.e., plasticity) or independently from these (within‐environment trait variability) might be particularly relevant nectar, which rapid needed population persistence improve chance animal‐mediated dispersal. In article, we microbiome as example encourage further research causes consequences plasticity within‐environment variability microbes. We review previous work mechanisms potential significance displayed by Additionally, provide overview some topics require attention, trade‐offs traits are adaptation dynamic environments direct indirect effects fitness flower‐visiting other conclude microbes essential get better understanding community assembly establishment interactions similar strongly selective habitats.

An emerging focus of research at the intersection botany, zoology, and microbiology is study floral nectar as a microbial habitat, referred to microbiome, which can alter plant-pollinator interactions. Studies on these communities have primarily focused yeasts, it was only about decade ago that bacteria began be studied widespread inhabitants nectar. This review aims give an overview current knowledge bacteria, with emphasis evolutionary origin, dispersal mode, effects chemistry plant-animal interactions, community assembly, agricultural applications, their use model systems in ecological research. We further outline gaps our understanding significance microorganisms, response environmental changes, potential cascading effects.
