“…Endophytic fungi are a diverse group, inhabiting and degrading terrestrial ( Arnold, 2007 ; Kusari et al, 2012 ; Rana et al, 2019 ; Yan et al, 2019 ; Manganyi and Ateba, 2020 ) and marine vegetation ( Hamzah et al, 2018 ; Noorjahan et al, 2019 ; Teixeira et al, 2019 ; Parthasarathy et al, 2020 ; Calado et al, 2021 ), linking ecology to plant pathology ( Shipunov et al, 2008 ; Behie and Bidochka, 2014 ; Leach et al, 2017 ; Latz et al, 2018 ; Poveda et al, 2020 ), and evolution ( Miyauchi et al, 2020 ; Tiwari and Bae, 2020 ), as well as plant communication and nutrient distribution ( Kothe and Turnau, 2018 ; Sharifi and Ryu, 2021 ). Endophytic fungi live in symbiosis within the macroalgae, as in terrestrial vegetation ( Jia et al, 2016 ), or in marine vegetation ( Hamzah et al, 2018 ; Noorjahan et al, 2019 ; Calado et al, 2021 ) and are likely to regulate many biochemical pathways through their life cycle ( Navarro-Meléndez and Heil, 2014 ; Latz et al, 2018 ). Clearly, endophytic fungi are likely of considerable importance, potentially for OM degradation (macrophytes, or other vegetation sources) and C cycling in terrestrial and marine environments.…”
