“…Based on recent findings (Carella et al, 2018;Matei et al, 2018) there is evidence for a tissue or organ specificity of non-host resistance, in line with physiological peculiarities (Miyawaki et al, 2004;Bednarek et al, 2005;Toruño et al, 2016). Support for the hypothesised tissue specificity of non-host resistance comes from the fact that closely related pathogens on unrelated hosts often occur in similar tissues.…”

Summary Host jumping is a process by which pathogens settle in new host groups. It is a cornerstone in the evolution of pathogens, as it leads to pathogen diversification. It is unsurprising that host jumping is observed in facultative pathogens, as they can reproduce even if they kill their hosts. However, host jumps were thought to be rare in obligate biotrophic pathogens, but molecular phylogenetics has revealed that the opposite is true. Here, I review some concepts and recent findings and present several hypotheses on the matter. In short, pathogens evolve and diversify via host jumps, followed by radiation, specialisation and speciation. Host jumps are facilitated by, for example, effector innovations, stress, compatible pathogens and physiological similarities. Host jumping, subsequent establishment, and speciation takes place rapidly – within centuries and millennia rather than over millions of years. If pathogens are unable to evolve into neutral or mutualistic interactions with their hosts, they will eventually be removed from the host population, despite balancing trade‐offs. Thus, generally, plant pathogens only survive in the course of evolution if they jump hosts. This is also reflected by the diversity patterns observed in many genera of plant pathogens, where it leads to a mosaic pattern of host groups over time, in which the original host group becomes increasingly obscure.

“…Similarly, other mosses, including Funaria hygrometrica , also form papillae around fungal penetration sites to prohibit their entry [64,65]. Callose deposition was also observed in the interaction between the liverwort M. polymorpha and the oomycete Phytophthora palmivora [66]. …”

All land plants must cope with phytopathogens. Algae face pathogens, too, and it is reasonable to assume that some of the strategies for dealing with pathogens evolved prior to the origin of embryophytes – plant terrestrialization simply changed the nature of the plant-pathogen interactions. Here we highlight that many potential components of the angiosperm defense toolkit are i) found in streptophyte algae and non-flowering embryophytes and ii) might be used in non-flowering plant defense as inferred from published experimental data. Nonetheless, the common signaling networks governing these defense responses appear to have become more intricate during embryophyte evolution. This includes the evolution of the antagonistic signaling pathways of jasmonic and salicylic acid, multiple independent expansions of resistance genes, and the evolution of resistance gene-regulating microRNAs. Future comparative studies will illuminate which modules of the streptophyte defense signaling network constitute the core and which constitute lineage- and/or environment-specific (peripheral) signaling circuits.

“…Terrestrial plants are thought to have evolved as the result of an ancient symbiosis between a semi-aquatic green alga and an aquatic fungus, borne onto land over 450 millennia ago (Delaux et al 2015). In this model, the colonization of land by plants-and therefore their very evolution-was only possible through an intimate partnership with a filamentous microorganism (Ponce de León and Montesano 2017; Carella et al 2017;Wang et al 2012).…”

“…Interestingly, this foundational fungal symbiosis may have come at a cost, since some microbes appear to have co-opted plant's symbiont accommodation to establish pathogenic interactions early on during land plant evolution (Wang et al 2012). Indeed, some of the genes required for fungal symbiosis in plants are necessary for extensive colonization by biotrophic pathogens (Wang et al 2012;Carella et al 2017). However, the topic appears to be somewhat controversial (Huisman et al 2015).…”

Plant-microbe interactions are great model systems to study co-evolutionary dynamics across multiple timescales, ranging from multimillion year macroevolution to extremely rapid evolutionary adaptations. However, mechanistic research on plant-microbe interactions has often been conducted with little consideration of the insights that can be gained from evolutionary concepts and methods. Conversely, evolutionary research has rarely integrated the diverse range of molecular mechanisms and models that continue to emerge from the molecular plant-microbe interactions field. These trends are changing. In recent years, the incipient field of evolutionary molecular plant-microbe interactions (EvoMPMI) has emerged to bridge the gap between mechanistic molecular research and evolutionary approaches. Here, we report on recent advances in EvoMPMI. In particular, we highlight new systems to study microbe interactions with early diverging land plants, and new findings from studies of adaptive evolution in pathogens and plants. By linking mechanistic and evolutionary research, EvoMPMI promises to add a new dimension to our understanding of plant-microbe interactions.
