“…Plants make use of a signaling module for recognition and establishment of the symbiosis, the main factors of which have already been present before the water-to-land transition of plants ( Delaux et al, 2015 ). This might indicate that these factors are also important for microbial interactions in an aquatic environment, which are also common although so far less studied ( Hempel et al, 2008 ; Rodriguez et al, 2009 ; Wurzbacher et al, 2010 ; Kataržytė et al, 2017 ). This view is supported by the fact that root nodule symbioses also make use of the CSP to establish plant–bacterial symbiosis ( Oldroyd, 2013 ).…”

Evolution of the Symbiosis-Specific GRAS Regulatory Network in Bryophytes

Arbuscular mycorrhiza is one of the most common plant symbiotic interactions observed today. Due to their nearly ubiquitous occurrence and their beneficial impact on both partners it was suggested that this mutualistic interaction was crucial for plants to colonize the terrestrial habitat approximately 500 Ma ago. On the plant side the association is established via the common symbiotic pathway (CSP). This pathway allows the recognition of the fungal symbiotic partner, subsequent signaling to the nucleus, and initiation of the symbiotic program with respect to specific gene expression and cellular re-organization. The downstream part of the CSP is a regulatory network that coordinates the transcription of genes necessary to establish the symbiosis, comprising multiple GRAS transcription factors (TFs). These regulate their own expression as an intricate transcriptional network. Deduced from non-host genome data the loss of genes encoding CSP components coincides with the loss of the interaction itself. Here, we analyzed bryophyte species with special emphasis on the moss Physcomitrella patens, supposed to be a non-host, for the composition of the GRAS regulatory network components. We show lineage specific losses and expansions of several of these factors in bryophytes, potentially coinciding with the proposed host/non-host status of the lineages. We evaluate losses and expansions and infer clade-specific evolution of GRAS TFs.

“…Simultaneously, an increased occurrence of microorganisms (fungi), especially on female gametangia, was observable (Figure 7). Different associated fungi's have been identified as endo-and epiphytes (Katarzytėet al, 2017). Detailed interactions and effects on fructification as well as underling gene metabolisms have been proven in further studies.…”

For studying land plant evolution, the establishment and optimization of model organisms representing streptophytic algae, sister to land plants, is essential. Long-term cultivation experiments with Chara braunii S276 were performed over 8 years, since 4 years (Nov. 2018) under constant conditions. Additionally, short-term experiments for optimization of culture conditions were performed with three strains of C. braunii (S276, NIES-1604 and Lausiger Teiche, LaT-2708). Germination success after application of sterilization agents, addition of gibberellic acid and under different incubation conditions with respect to pre-treatment, irradiance regime and substrate was investigated in order to develop protocols for generative cultivation of at least unialgal cultures. The resulting cultivation protocols for C. braunii S276, allowing maintenance of vegetative as well as generative cultures are presented in detail, including protocols for germination induction and growth of sterilized and unsterilized oospores.

“…Beach wrack (that consists of organic material) and accumulates along the coast with significant amounts can also be a primary and significant source for higher fungal abundance. Rhodotorula, Alternaria and Aspergillus species, for example, are associated with live or decomposing aquatic or terrestrial plants or algae (Kataržytė et al, 2017;Ogaki et al, 2019).…”
