“…However, we failed to detect any phylosymbiosis evidence between the sampled 15 bamboo species and their microbiota by comparing the phylogeny congruence based on both host's cpDNA matrix and endophytic 16S rRNA sequences (Mantel statistic r = −0.1809, P = 0.966). Similar result was detected between skin microbiome and host phylogeny in the case of carnivores (Ross et al, 2018). O'Brien et al (2020 proposed three main reasons why phylosymbiosis does not occur.…”

“…In this study, we found that host identity and their lifeforms didn't significantly influence the root and leaf microbiota. Patterns of phylosymbiosis may be dependent on a certain host taxonomic level (i.e., family), where bamboo identity effects are reduced and their physiological traits and phylogeny are congruent (O'Brien et al, 2020). The long evolutionary history of bamboos (28.26 Mya) (Zhang et al, 2016), as well as the extremely long intervals between flowering periods (7-120 years) (Kelchner and Bamboo, 2013) would have contributed to phylosymbiosis between host bamboos and microbiota.…”

“…Phylosymbiosis is a newly formulated concept referring to the process by which the phylogeny of host species parallels the ecological relatedness of corresponding microbial communities ( Brooks et al, 2016 ; Lim and Bordenstein, 2020 ; O’Brien et al, 2020 ). This relationship has been detected in a diverse range of taxa and environments, e.g., the gut microbiome of mammals and insects ( Kohl et al, 2018 ), the microbiome of coral reef invertebrates ( O’Brien et al, 2020 ), and the root microbiome of plants ( Yeoh et al, 2017 ). Phylosymbiosis is observed at one moment in time and space, which does not necessarily imply coevolution of hosts and their microbiota, but coevolution may be one mechanism contributing to observations of phylosymbiosis ( O’Brien et al, 2020 ).…”

Leaves and roots harbor taxonomically diverse bacterial assemblages which enhance plant growth and performance by increasing nutrient supply and resistance to stress. An extensive investigation of bacterial diversity and composition between leaf and root microbiota of 15 bamboo species differing in rhizome types, lifeforms and sampling sites were conducted by high-through sequencing. The alpha diversity between leaf and root microbiota was not significantly different, whereas, their beta diversity differed remarkably. Niche specialization mainly in species from Actinobacteria was detected which prefer to colonize in roots than leaves. Community structure of leaf microbiota was highly resembled, however, the phylogeny inferred by host's chloroplast data was incongruent with microbiota dendrogram, indicating that phylosymbiosis didn't occur in bamboos and their associated microbiota. Large overlap in functional profiling of leaf and root-associated microbiota was found. Accordingly, we proposed that environmental conditions, structural variation and physiological differences between leaves and roots worked collaboratively for divergence of bamboo microbiota. This study confers to a robust knowledge of bamboo-microbe interaction and provides a list of bacterial lineages for investigation into specific plant-microbe interaction information of which could be used to enhance agricultural and forest productivity.

Plant abundance, but not plant evolutionary history, shapes patterns of host specificity in foliar fungal endophytes

Understanding the origins and maintenance of host specificity, or why horizontally-acquired symbionts associate with some hosts but not others, remains elusive. In this study, we explored whether patterns of host specificity in foliar fungal endophytes, a guild of highly diverse fungi that occur within the photosynthetic tissues of all major plant lineages, were related to characteristics of the plant community. We comprehensively sampled all plant host species within a single community and tested the relationship between plant abundance or plant evolutionary relatedness and metrics of endophyte host specificity. We quantified host specificity with methods that considered the total endophyte community per plant host (i.e., multivariate methods) along with species-based methods (i.e., univariate metrics) that considered host specificity from the perspective of each endophyte. Univariate host specificity metrics quantified plant alpha-diversity (structural specificity), plant beta-diversity (beta-specificity), and plant phylogenetic diversity (phylogenetic specificity) per endophyte. We standardized the effect sizes of univariate host specificity metrics to randomized distributions to avoid spurious correlations between host specificity metrics and endophyte abundance. We found that more abundant plant species harbored endophytes that occupied fewer plant species (higher structural specificity) and were consistently found in the same plant species across the landscape (higher beta-specificity). There was no relationship between plant phylogenetic distance and endophyte community dissimilarity. We still found that endophyte community composition significantly varied among plant species, families, and major groups, supporting a plant identity effect. In particular, endophytes in angiosperm lineages associated with narrower phylogenetic breadths of plants (higher phylogenetic specificity) compared to endophytes within conifer and fern lineages. Overall, an effect of plant species abundance may help explain why horizontally-transmitted endophytes vary geographically within host species ranges.
