Common symbiosis signaling pathway
The common symbiosis signaling pathway (CSSP) is a signaling cascade in plants that allows them to interact with symbiotic microbes. It corresponds to an ancestral pathway that plants use to interact with arbuscular mycorrhizal fungi (AMF). It is known as "common" because different evolutionary younger symbioses also use this pathway, notably the root nodule symbiosis with nitrogen-fixing rhizobia bacteria. The pathway is activated by both Nod-factor perception (for nodule forming rhizobia), as well as by Myc-factor perception that are released from AMF. The pathway is distinguished from the pathogen recognition pathways, but may have some common receptors involved in both pathogen recognition as well as CSSP. A recent work [1] by Kevin Cope and colleagues showed that ectomycorrhizae (a different type of mycorrhizae) also uses CSSP components such as Myc-factor recognition.
The AMF colonization requires the following chain[2] of events that can be roughly divided into the following steps:
1: Pre-Contact Signaling
2: The CSSP
2: A: Perception
2: B: Transmission
2: C: Transcription
3: The Accommodation program
Outline
[edit]To accurately recognize the infection thread of a different species of organism, and to establish a mutually beneficial association requires robust signaling.[3] AM fungi are also fatty acid auxotrophs;[4][2] therefore they depend on a plant for supply of fatty acids.[5]
At the pre-symbiotic signaling, plants and AMF release chemical factors in their surroundings so that the partners can recognise and find each other.[6]' Plant root exudates play roles in complex microbial interaction,[7] by releasing a variety of compounds,[7][8][9] among which strigolactone has been identified to facilitate both AMF colonisation and pathogen infection.[8]
Phosphate starvation in plant induces strigolactone production as well as AMF colonisation.[8] Plants release strigolactone, a class of caroteinoid-based plant hormone, which also attracts the fungal symbionts, and stimulate the fungal oxidative metabolism along with growth and branching of the fungal partner. [2] Strigolactone promotes hyphal branching in germinating AMF spores and facilitates colonisation. [9] [10]
The common symbiosis signalling pathway is called so because it has common components for fungal symbiosis as well as rhizobial symbiosis. The common signalling pathway probably evolved when the existing pathway for arbuscular mycorrhizae was exploited by rhizobia.[2][11]
The perception happens when fungal Myc factor is detected by the plant. Myc factors are comparable to rhizobial nod factors. The chemical nature of some Myc-factors has recently been revealed as lipo-chito-oligosaccharide (Myc-LCOs) and chito-oligosaccharides (Myc-COs) that work as symbiotic signal.[10][12][13]
The presence of Strigolactone enhances the production of Myc-CO production by AMF.[10]
Myc-factor receptor (MFR) is still putative. However, a protein called DMI2 (or SYMRK) has a prominent role in perception process and it is thought to be a co-receptor of MFR. Other plants such as rice may employ different mechanisms using OsCERK1 and OsCEBiP to detect chitin oligomers.[2][14][15] However, recent work has demonstrated that rice SYMRK is essential for AM symbiosis.[16]
The transmission happens when the signal is transmitted after detection to the plant nucleus. This process is mediated by two nucleoporins NUP85 and NUP133,[11] Alternatively, another hypothesis says HMG-CoA reductase is activated on perception, which then converts HMG-CoA into mevalonate. This mevalonate acts as a second messenger and activates a nuclear K+ cation channel (DMI-1 or Pollux).[2][17] The transmission stage ends by creating a ‘calcium spike’ in the nucleus. [18]
The transcription stage starts when a Calcium and Calmodulin dependent kinase (CCaMK) is activated.[2] This kinase stimulates a target protein CYCLOPS.[2] CCaMK and CYCLOPS probably forms a complex that along with DELLA protein, regulates the gene expression of RAM1 (Reduced Arbuscular Mycorrhyza1).[2]
The accommodation process involves the extensive remodelling of host cortical cells. This includes invagination of host plasmalemma, proliferation of endoplasmic reticulum, golgi apparatus, trans-golgi network and secretory vesicles. Plastids multiply and form “stromules”. Vacuoles also undergoe extensive reorganization.[11]
The Pre-Contact Signaling
[edit]Chemical signalling starts prior to the two symbionts coming into contact. From the host plant's side, it synthesizes and releases a range of caroteinoid based phytohormone, called strigolactones.[2] They have a conserved tricyclic lactone structure also known as ABC rings.[19] Strigolactone biosynthesis occurs mainly in plastid,[20] where D27 (Rice DWARF 27; Arabidopsis ortholog ATD27), an Iron binding beta-carotene isomerase works at upstream of strigolactone biosynthesis. [20] Then carotenoid cleavage dioxygenase enzyme CCD7 and CCD8 modifies the structure, which has following orthologs:
Gene name | Localization | function | Rice ortholog | Pea ortholog | Petunia ortholog | Arabidopsis ortholog |
---|---|---|---|---|---|---|
CCD7 | Plastid proteins | involved in strigolactone biosynthesis | D17/ HTD1 | RMS5 | DAD3 | MAX3 |
CCD8 | Plastid proteins | involved in strigolactone biosynthesis | D10 | RMS1 | DAD4 | MAX4 |
Alpha/Beta fold hydrolase | Nuclear proteins | involved in strigolactone perception | D14 | RMS3 | DAD2 | ? |
The alpha/beta fold hydrolase D3 and also D14L (D14-Like) (the later one has an Arabidopsis ortholog, KAI2, or KARRIKIN INSENSITIVE-2) is reported to have important roles in mycorrhizal symbiosis,[21] notably, D3, D14 and D14L are localised in the nucleus.[2]
NOPE1 or 'NO PERCEPTION 1', is a transporter protein in Rice (Oryza sativa) and Maize (Zea mays), also required for the priming stage for colonisation by the fungus. NOPE1 is a member of Major Facilitator Super family of transport proteins, capable of N-acetylglucosamine transport. Since nope1 mutants root exudates fail to elicited transcriptional responses in fungi, it strongly seems that NOPE1 secretes something (not yet characterised) that promotes fungal response.[22]
Perception
[edit]There are two main type of root symbiosis; one is root nodule symbiosis by Rhizobia (RN-type) and another is Arbuscular Mycorrhiza (AM-type). There are common genes involved in between these two pathways.[23] these key common components, form the Common Symbiosis pathway (CSP or CSSP).[23] It has been proposed that, RN symbiosis has originated from AM symbiosis.[11] The perception of the presence of the fungal symbiont takes place mainly through fungal chemical secretions generally termed as Myc-factors. Receptors for Myc-factors are yet to be identified. However, DMI2/SYMRK probably acts as a co-receptor of Myc factor receptor (MFR). The AM fungal secreted materials relevant to symbiosis are Myc-LCOs, Myc-COs, N-Acetylglucosamine [2][24]

---|---|
Myc-LCOs | LYS11 in Lotus japonicus |
Short chain chitin oligomers (COs) | OsCERK1 and OsCEBiP in rice |
N-acetylglucosamine | NOPE-1 in maize |
Fungal Molecules that triggers CSSP
[edit]Myc-LCOs (lipochitooligosaccharides)
[edit]Like Rhizobial LCOs (Nod factors); Myc-LCOs play important role in perception stage. They are a kind of secreted compounds from AM fungi, mainly mixtures of lipo-chito-oligosaccharides (Myc-LCOs). In Lotus japonicus, LYS11, a receptor for LCOs, was expressed in root cortex cells associated with intra-radical colonizing arbuscular mycorrhizal fungi [24]
Short chain chitin oligomers (Myc-COs)
[edit]AM host plants show symbiotic-activated calcium waves upon exposure to short chain chitin oligomers. It has been reported that production of these molecules by the AM fungus Rhizophagus irregularis, is strongly stimulated upon exposure to strigolactones. [2] This suggests that plants secrete strigolactones and in response, the fungus increases short chain chitin oligomers, which in turns elicits the plant response to accommodate the fungus. The lysine motif domain of OsCERK1 and OsCEBiP is thought to be involved in the perception of short chain chitin oligomers.[2]
NOPE-1 is transporter (described above). NOPE-1 also shows a strong N-acetylglucosamine uptake activity, and is thought to be associated with recognition of presence of fungal symbiont.[2]
Some plant proteins are suspected to recognise Myc-factors, and the rice OsCERK1 Lysin motif (LysM) receptor-like kinase, is one of them.[15]
Cell Surface Receptors
[edit]There are multiple families of pattern recognition receptors and co-receptors involved in recognition of microbial pathogens and symbionts. Some of the relevant families involved in CSSP, are Membrane bound LysMs (LYM), Soluble LysM Receptor like Protein, LYK (LysM receptors with active Kinase domain), LYR (LysM proteins with inactive kinase domain), etc.
Seemingly, different combinations of a LYK and LYR receptors perceive and generate differential signals, such as some combinations generate a pathogen recognition signal whereas some combinations generate symbiotic signals. [25][26][27][28]
Receptor-like Kinases (RLKs)
[edit]DMI2/ SYMRK is a receptor-like kinase, an important protein in endosymbiosis signal perception, reported in several plants (Mt-DMI2 or Mt-NORK in Medicago trancatula; Lj-SYMRK in Lotus japonicas; Ps-SYM19 in Pisum sativum; OsSYMRK in Rice). OsSYMRK lacks an N-terminal domain and exclusively regulate AM symbiosis (is not involved in the RN symbiosis).[29] Notably, it has been found that a Nod-factor inducible gene, MtENOD11, is activated in the presence of AMF exudates; little is known about this phenomenon.[30][31]
LysM receptor-like kinase
[edit]Lysin Motif (LysM) receptor-like kinase are a subfamily related to membrane bound Receptor-like kinase (RLKs) with an extracellular region consisting of 3 Lysine motifs. They have some important orthologs in different plants, that vary in their function. In some plant species they are involved in AM symbiosis, in others they are not. Tomato (Solanum lycopersicum), a non-legume eudicot, also have a similar LysM receptor, SlLYK10 that Promotes AM symbiosis. There are some co-receptors of Myc-factor receptor viz., OsCEBiP in Rice, a LysM membrane protein can function as a co-receptor of OsCERK1 but it participates in a different pathway.[32][33][34]
Most of these kinases are serine/threonine kinases, some are tyrosine kinases.[27] Also, they are type-1 transmembrane proteins, that indicates their N-terminal domain towards the outside of the cell, and the C-terminal domain is towards inside of the cell.[27]

Transmission
[edit]The transmission of signal cascades into the nucleus is not well understood. However, this transmission includes carrying the message up to the nuclear membrane and generation of a calcium wave.[35] Some elements involved in this process are:
Nucleoporins
[edit]Lotus japonicus Nucleoporins LjNUP85 and LjNUP133 has potential role in transmission of the signal.[36] Lj-NENA is another important nucleoporin that plays role in AM symbiosis.[29]
HMGR and Mevalonate.
[edit]It has been proposed that the enzyme 3-hydroxy-3-methylglutaryl-CoA reductase (HMG CoA reductase or HMGR) has potential role in the transmission stage. The enzyme is activated by SYMRK/DMI2, and forms mevalonate.[37][38] This mevalonate acts as a second messenger, and activates a nuclear potassium channel, DMI1 or POLLUX.[38]

Calmodulin is a widespread regulatory protein that functions along with Ca2+ in various biological processes. In AM symbiosis signalling, it modulates CCaMK.[37] CCaMK or DMI3 is a calcium-and-calmodulin-dependent kinase (CCaMK) thought to be a key decoder of Ca2+ oscillations and an important regulatory kinase protein. Nuclear Ca2+ spiking promotes binding of Ca2+ calmodulin with CCaMK.[37] Binding of Ca2+ calmodulin with CCaMK causes conformational change of CCaMK that stimulates a target protein, CYCLOPS, which has different orthologs.[37] CYCLOPS is a coiled coil domain containing protein [37] possibly form a complex with CCaMK[37] that works along with DELLA proteins. DELLA proteins are a kind of GRAS-domain protein originally identified as repressors of the Gibberellin signalling pathway, however now it is seen that DELLA participates in many signalling pathways.[40] There are two DELLA proteins in Medicago trancatula and Pisum sativum that play a role in symbiosis whereas in rice only one DELLA protein fulfils this task.[37] Reduced Arbuscular Mycorrhiza or RAM1[37] is a GRAS[41] protein whose gene is directly regulated by DELLA and CCaMK/ CYCLOPS.[37] By using chromatin immunoprecipitation assays, it has been shown that RAM1 binds to RAM2 gene promoter.[37] RAM1 also regulates many of the plant genes that participate in AMF accommodation.
Some GRAS proteins play a role in AM symbiosis but these roles are not yet fully understood. These include RAM1, RAD1 (REQUIRED FOR ARBUSCLE DEVELOPMENT 1), MIG1 (MYCORRHIZA INDUCED GRAS1), NSP1 and NSP2.[42] WRKY transcription factor genes are thought to play very important roles in establishment of mycorrhizal symbiosis and they perhaps work through regulating plant defense genes.[43]
The Accommodation program
[edit]Root cortex cells experience important changes in order to accommodate for the fungal endosymbiont. The pre-penetration apparatus (PPA) in outer cell layers and the peri-arbuscular membrane that surrounds arbuscules in inner cell layers need to be formed and the plant cell cytoplasm needs to rearrange,[36] the vacuole retracts in size, the nucleus and nucleolus enlarge in size and chromatin decondense indicating heightened transcriptional activity.[36] Plastids multiply and stay connected with “stromulus”.[36] Furthermore, it was suggested that the apoplastic longitudinal hyphal growth is probably regulated by plant genes such as taci1 and CDPK1.[44]
Genes and proteins playing a role in the accommodation programme
[edit]Although various proteins have been identified which may play role on how this accommodation process occurs, the detailed signalling cascade is not fully understood. Some of the proteins and mechanisms involved in the deposition on peri-arbuscular membrane are EXOCYST complex, EXO70 subunit, a symbiosis-specific splice variant of SYP132, VAPYRIN, and two variants of VAMP721.[37] Plant enzymes FatM and RAM2[45] and ABC transporter STR/STR2 are putatively involved in the synthesis and supplying of a lipid 16:0 β-monoacylglycerol to the AM fungi.[45][46] Recently discovered kinases that regulate the AMF accommodation programm include ADK1,[47] AMK8, AMK24,[48] ARK1[49] and ARK2.[50]
The protein composition of the peri-arbuscular membrane is very different from that of the plasma membrane. It includes some special transporters such as phosphate transporters (Mt-PT4, Os-PT11, Os-PT13) and ammonium transporters (Mt-AMT2 and 3). It also includes ABC transporters such as STR/STR2 putatively involved in lipid transport.[37][51]
Evolutionary significance
[edit]AM fungi and plants co-evolved and developed a very complex interaction that allow the plant accommodate the AM-fungal host.[52][53][54] It has been proposed that the RN symbiosis has originated from the AM symbiosis.[36][29]
