Plant SYP12 syntaxins mediate an evolutionarily conserved general immunity to filamentous pathogens

Abstract: 27Many filamentous fungal and oomycete plant pathogens invade by direct penetration through 28 the leaf epidermal cell wall and cause devastating plant diseases. In response to attack, plants 29 form evolutionarily conserved cell autonomous defense structures, named papillae and 30 encasements, that are thought to block pathogen ingress. Previously, the syntaxin PEN1 in 31 Arabidopsis, like its orthologue ROR2 in barley, was found to mediate pre-invasive immunity 32 towards powdery mildew fungi, where it… Show more

“…Recently, Rubiato et al . (2021) provided evidence for an evolutionarily conserved role of SYP12 proteins in the formation of papillae and encasements at pathogen penetration sites, which are effective defence structures against a broad range of filamentous pathogens. Together, our data suggest a function of MpSYP12A in penetration resistance and responses to filamentous pathogens, such as SYP12 proteins in other plant species.…”

“…During land plant evolution, the expansion of SNARE proteins and their functional diversification was hypothesized to be linked to multicellularity and probably facilitated adaptation to a terrestrial lifestyle (Sanderfoot, 2007). Thus, land plant secretory pathways are highly sophisticated, dynamic and diversely regulated, being involved in a manifold of cellular processes ranging from polarized growth to defence responses (Batoko & Moore, 2001; Collins et al ., 2003; Catalano et al ., 2007; Enami et al ., 2009; Silva et al ., 2010; Reichardt et al ., 2011; Uemura et al ., 2012; Ichikawa et al ., 2014; Johansson et al ., 2014; Yun et al ., 2016; Xia et al ., 2019; Hirano et al ., 2020; Rubiato et al ., 2021). In M. polymorpha , the SYP1 protein family consists of four members: SYP12A, SYP12B, SYP13A and SYP13B.…”

“…It is becoming increasingly clear that immunity often is dependent on fundamental cellular processes such as membrane trafficking (e.g. Ortmannová et al ., 2022; Rubiato et al ., 2022), which therefore are potential effector targets. We also know that the NLR-based surveillance system monitors components targeted by pathogens and kills the cell when activated.…”

“…The syntaxin PEN1 (SYP121), as well as its barley orthologue ROR2, are required for timely papilla formation (Assaad et al ., 2004; Böhlenius et al ., 2010). Meanwhile, PEN1 and its closest homologue, SYP122, have a shared function in papilla and encasement formation per se (Rubiato et al ., 2022). These syntaxins are likely required for fusion of multivesicular bodies (MVBs) to the PM at the site of fungal attack to mediate papilla and encasement formation.…”

“…In addition to immunity, VAMP721/722 are also involved in growth, cell division and stress responses (Kwon et al ., 2008; El Kasmi et al ., 2013; Ichikawa et al ., 2014; Park et al ., 2018; Kim et al ., 2021; Rubiato et al ., 2022). This diverse biological functions of VAMP721/722 are attributed to their interaction with distinct PM Qa‐SNAREs (SYP111 (also called KNOLLE) and SYP132 for cell division, SYP123 and SYP132 for growth, and SYP121, SYP122 and SYP132 for immunity).…”
