“…Two papers identified seed endophytes from a range of species stored in seed banks. Of the peer reviewed papers surveying wild species, four investigated endophytes from Australian native plant species, namely, Glycine clandestine, a wild soybean relative, (Chandel et al 2022) and the aquatic seagrass Halophila ovalis (Tarquinio et al 2021), our own work on the Australian endemic genus Banksia (Mertin et al 2022) and the work of Aldous et al (1999) on a range of native Australian grasses. Our work on B. serrata and B. ericifolia, where seeds and maternal lines were kept separate, found that culturable fungi were present across all sites, individuals and species (van der Merwe 2021; Mertin et al 2022).…”

Integrating seed microbiome knowledge into restoration and ex situ conservation of native Australian plants

Context Seeds harbour a diversity of microbes, which in some plants aid with germination and establishment. Seeds form a critical part in the lifecycle of plants and a role in many conservation and restoration activities. Aims Because this is an emerging field in seed biology, we aim to highlight the key research gaps of interest to seed on the basis of restoration and ex situ conservation. Methods We identify knowledge gaps associated with the seed endophytic microbiome of native Australian plants through undertaking a literature review. Additionally, culturing methods were used to identify the fungal seed endophytes of five native Australian species. Key results We identified a diversity of taxa within the native seed and show three taxa that are common to all study hosts. Sampling seed from additional hosts at a site and additional sites of a host species showed new fungal diversity. Our literature review showed that little information is available on native seed microbiomes and we identified four key areas where research gaps exist, linking with seed-based restoration practices. Conclusions We provide evidence that there is a complex and diverse seed microbiome within some Australian native plants and suggest ways that it could be integrated into restoration and conservation practices. Implications We propose that by taking into consideration the presence of a seed microbiome and its potential impacts on plant health, seed microbiomes could be used as one method to restore microbial diversity into an ecosystem and to contribute to the seedling microbiome and plant health at restored sites.
