“…In O. sativa , proteins that were significantly increased in abundance included three fasciclin-like arabinogalactan proteins (FLAs) (A2YWR4, A2XUI8 and A2YTW2) ( Fig. 5C ), a subclass of arabinogalactan proteins (AGPs), regulating functions linked to cell wall biosynthesis, cell adhesion and signaling ( Wu et al. 2020 ).…”

Symbiosis between cyanobacteria and plants is considered pivotal for biological nitrogen deposition in terrestrial ecosystems. Despite extensive knowledge of the ecology of plant-cyanobacterium symbioses, little is known about the molecular mechanisms involved in recognition between partners. Here, we conducted a quantitative sequential window acquisition of all theoretical fragment ion spectra mass spectrometry (SWATH-MS) pipeline to analyse protein changes in Oryza sativa and Nostoc punctiforme during early events of symbiosis. We found differentially expressed proteins in both organisms linked to several biological functions, including signal transduction, adhesion, defence-related proteins, and cell wall modification. In Nostoc punctiforme we found increased expression in 62 proteins that have been previously described in other Nostoc-plant symbioses, reinforcing the robustness of our study. Our findings reveal new proteins activated in the early stages of the Nostoc-Oryza symbiosis that might be important for the recognition between the plant and the host. Oryza mutants in genes in the common symbiosis signalling pathway (CSSP) show a reduced colonization efficiency providing first insights on the involvement of the CSSP for the accommodation of N. punctiforme inside the plant cells. This information may have long-term implications for a greater understanding of the symbiotic interaction between Nostoc and land plants.

“…In O. sativa –AM fungi symbiosis, the plant activates the expression of three FLAs ( Gutjahr et al. 2015 ), which are a subclass of AGPs important for plant development, cell adhesion and signaling ( Ma and Zhao 2010 , Seifert 2018 , Wu et al. 2020 ).…”
