“…The hyphopodium development is associated with the induction of lectin genes, which possibly identify the compatibility of mycorrhizal partners (Bapaume et al, 2012;Czaja et al, 2012;Garg et al, 2019). Russo et al (2019) observed the TPLATE promoter is activated in colonized cells of the root cortex where we also observed the appearance of cells that are half the size of the surrounding cells developing cell plates highlighted ectopic cell division events in the inner root cortex during early AM colonization.…”

“…The adhesion of hyphopodium to the root surface is regulated by ligands present in the cell wall (lectins), which signal internally and induce the formation of a penetration apparatus in the epidermal cell (Genre et al, 2005;Garg et al, 2019). The epidermal cell nucleus is moved by the cytoskeleton, directly positioning below the contact site of the hyphopodium in approximately 2 hours, from the fixation of the hypha to the complete migration of the nucleus (Genre et al, 2005).…”

“…The epidermal cell nucleus is moved by the cytoskeleton, directly positioning below the contact site of the hyphopodium in approximately 2 hours, from the fixation of the hypha to the complete migration of the nucleus (Genre et al, 2005). Microtubule aggregation and calcium concentration fluctuations, known as calcium spiking, are initially observed (Grunwald et al, 2014;Garg et al, 2019). Then, the nucleus is directed to the other end of the cell, and in this pathway, the microtubule aggregation accompanies the nucleus, forming a hollow column, which corresponds to the penetration apparatus, formed between 4 and 5 hours (Genre et al, 2005).…”

This review analyzes the physiological, biochemical and molecular implications related to the interaction between arbuscular mycorrhizal fungi (AMF) and plants in the pre-symbiotic and symbiotic stages. Factors involving spore germination, germ tube growth, signaling and recognition of mycorrhizal fungi are discussed from a macro context, in which the plant interacts with the environment, to a most intrinsic context, in which genes are involved in this interaction. The colonization stages, from the formation of hyphopodium to the differentiation of arbuscules, are described according to cellular changes and molecular mechanisms. The dynamics of nutrient exchanges are discussed bidirectionally, from the fungus to the plant and from the plant to the fungus.The regulation processes of absorption and transport of water, phosphorus, nitrogen and calcium, and carbohydrates via the periarbuscular membrane are described in cellular, functional and molecular terms. The most common changes in the secondary metabolism of plants associated to AMF are also presented, based on biochemical processes. The conjuncture analysis showed that in the last decade, studies made efforts to identify the mechanisms of communication and symbiosis functioning, differently from studies carried in the past decades, which extensively investigated the aspects related to the growth responses of symbionts, especially in plants.

“…trehalose 6phosphate gene) (Qin et al, 2018). Trehalose is an osmoprotectant, and its role in salt-stress tolerance has been well documented (Garg et al, 2019;Orozco-Mosqueda et al, 2019;Shim et al, 2019). Figueiredo et al (2008) reported that Rhizobium tropici and Paenibacillus polymyxa were modified to overexpress trehalose 6-phosphate gene and were co-inoculated in Phaseolus vulgaris plants resulting beneficial for plants grown under saline stress, with higher nodulation and N content.…”
