Intra-specific analyses revealed that diverse plant genotypes growing in similar habitats interact with a common set of microbial groups but that some of these core groups are species- or environment-specific. Furthermore, interspecific meta-analysis demonstrates the conservation of seven bacterial orders across diverse photosynthetic organisms, including microalgae, suggesting a conserved capacity for interaction with these core microbes throughout evolutionary history. However, the specific functions of these core members and whether these functions are conserved across hosts remain largely unexplored. I therefore discuss the importance of understanding the roles of the core microbiota and propose future research directions, including the exploration of microbial interactions across different kingdoms. By investigating the core microbiota and its functions, it will be possible to leverage this knowledge for sustainable agricultural management and conservation goals.</p></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":null,"pages":null},"PeriodicalIF":9.5,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1369526623001528/pdfft?md5=509b8cb71221700c574b88497674ea67&pid=1-s2.0-S1369526623001528-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138498056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In land plants, meristem maintenance leads to indeterminate growth and the production of new meristems leads to branching or regeneration via reprogramming of wounded somatic cells. Emerging model systems in the haploid dominant and monophyletic bryophytes are allowing comparative analyses of meristem gene regulatory networks to address whether all plants use common or diverse programs to organise, maintain, and regenerate meristems.
