“…Legume NOD FACTOR RECEPTOR 1 (NFR1) and rice CHITIN ELICITOR RECEPTOR KINASE 1 (CERK1) are homologous LysM RLKs on the cell membrane that act via association with other receptor‐like proteins (RLP, Kouzai et al ., ). In legumes, perception of both fungal and bacterial chitinaceous signals by nod‐factor receptors stimulates nuclear Ca 2+ ‐oscillations, and the activation of the Common Symbiosis Signalling Pathway (CSSP), a conserved signal transduction pathway which is necessary for root invasion by AMF and nitrogen‐fixing rhizobia (reviewed in Gobbato, ). The similar requirement for intact CSSP in rice indicated the taxonomically broad functional conservation (Gutjahr et al ., ).…”

Perception of arbuscular mycorrhizal fungi (AMF) triggers distinct plant signalling responses for parallel establishment of symbiosis and induction of lateral root formation. Rice receptor kinase CHITIN ELICITOR RECEPTOR KINASE 1 (CERK1) and α/β-fold hydrolase DWARF14-LIKE (D14L) are involved in pre-symbiotic fungal perception. After 6 wk post-inoculation with Rhizophagus irregularis, root developmental responses, fungal colonization and transcriptional responses were monitored in two independent cerk1 null mutants; a deletion mutant lacking D14L, and with D14L complemented as well as their respective wild-type cultivars (cv Nipponbare and Nihonmasari). Here we show that although essential for symbiosis, D14L is dispensable for AMF-induced root architectural modulation, which conversely relies on CERK1. Our results demonstrate uncoupling of symbiosis and the symbiotic root developmental signalling during pre-symbiosis with CERK1 required for AMF-induced root architectural changes.

“…These benefits result in a reduction of chemical inputs, environmental pollutants and production costs (Oliveira et al 2013, Zou et al 2013, Gobbato 2015, Pierart et al 2015. It has been particularly important in soils with low phosphorus levels, such as tropical soils and those under drought stress conditions (Yano & Takaki 2005, Osorio 2011, Ramirez et al 2013.…”

The cultivation of purple passion fruit plants has increased in Colombia, as a direct result of its well-accepted consumption. Therefore, there is a need for technological solutions aimed at the sustainable growth of its fruit, such as improving seed germination and decreasing phosphorus (P) deficiencies, given its low availability in tropical soils. This study aimed to evaluate pre-germination treatments (control, apical and basal seed cuts, alternation of temperature, photoperiod, application of gibberellic acid and immersion in 96 % of H2SO4) and mycorrhizal dependency of purple passion fruit plants, using three levels of P in the soil solution (0.002 mg L-1, 0.02 mg L-1 and 0.2 mg L-1), in 35 combinations with or without the inoculation of the Glomus fasciculatum mycorrhizal fungus. A completely randomized design with five replications per treatment was used. The treatment with the most significant effect for reducing the dormancy of the purple passion fruit seeds is the immersion in 96 % of H2SO4 for 20 minutes. This species shows a high mycorrhizal dependency, when coupled with 0.02 mg L-1 of P in the soil solution.

“…CCaMK is a central regulator of nodule organogenesis, rhizobia infection, and arbuscular mycorrhizal signaling (Gobbato, 2015;Miller et al, 2013;Shimoda et al, 2012). Recently, a growing body of evidence reveals additional functions of CCaMK, such as response to ABA signaling and stress tolerance in wheat, maize, and rice Shi et al, 2012;Yang et al, 2011a).…”

“…This model includes a two-step activation of CCaMK by Ca 2+ (Miller et al, 2013;Poovaiah et al, 2013). CCaMK is a central decoder of Ca 2+ -spiking in the common symbiosis pathway for regulating root nodules and arbuscular mycorrhizae (Gobbato, 2015;Miller et al, 2013;Shimoda et al, 2012). However, CCaMK is highly expressed outside of roots, indicating other roles besides the regulation of symbiosis.…”
