“…Moreover, both MtCLE13 and MtCEP7 were induced by cytokinin, and the effects of both peptides on nodulation were mediated by the cytokinin receptor gene MtCRE1 [ 45 ]. Studies on the crosstalk between peptide and classical hormones provide evidence that peptide signaling is interlinked with signaling through cytokinin, auxin, ethylene and strigolactones (for a recent review see [ 57 ]). The concurrent induction of the antagonistic CLE and CEP pathways may be part of a mechanism that enables the plant to flexibly adjust rhizobial infection events and the nodule numbers to its needs based on the endogenous supply status of various nutrients, photosynthetic capacity and environmental conditions.…”

“…Although CLE peptides may respond to diverse stimuli, the shoot-localized receptor Lj HAR1/ Mt SUNN/ Gm NARK/ Ps SYM29, may be a common component of the respective signaling mechanisms (discussed in [ 57 ]). In M. truncatula , downstream signaling of the AM-induced MtCLE53 , the rhizobium-induced MtCLE13 or the P-responsive MtCLE33 was dependent on SUNN in overexpression assays, implying SUNN as a common receptor for all three CLE peptides [ 45 , 46 ].…”

Plants engage in symbiotic relationships with soil microorganisms to overcome nutrient limitations in their environment. Among the best studied endosymbiotic interactions in plants are those with arbuscular mycorrhizal (AM) fungi and N-fixing bacteria called rhizobia. The mechanisms regulating plant nutrient homeostasis and acquisition involve small mobile molecules such as peptides and micro RNAs (miRNAs). A large number of CLE (CLAVATA3/EMBRYO SURROUNDING REGION-RELATED) and CEP (C-TERMINALLY ENCODED PEPTIDE) peptide hormones as well as certain miRNAs have been reported to differentially respond to the availability of essential nutrients such as nitrogen (N) and phosphorus (P). Interestingly, a partially overlapping pool of these molecules is involved in plant responses to root colonization by rhizobia and AM fungi, as well as mineral nutrition. The crosstalk between root endosymbiosis and nutrient availability has been subject of intense investigations, and new insights in locally or systemically mobile molecules in nutrient- as well as symbiosis-related signaling continue to arise. Focusing on the key roles of peptides and miRNAs, we review the mechanisms that shape plant responses to nutrient limitation and regulate the establishment of symbiotic associations with beneficial soil microorganisms.

“…Small molecules are ideal candidates for systemic signal propagation within the plant body and are potential targets for beneficial microbes. A recent review by Roy and Müller [ 88 ] summarized the importance of peptides under nutrient stress and plant-microbe interactions, and also described how a microbial peptide mimics or alters the host physiology to enhance colonization. The reannotation of bacterial genomes might help to identify new peptide candidates, connecting drought-tolerance responses in the host with symbiotic microbes.…”

In the wake of changing climatic conditions, plants are frequently exposed to a wide range of biotic and abiotic stresses at various stages of their development, all of which negatively affect their growth, development, and productivity. Drought is one of the most devastating abiotic stresses for most cultivated crops, particularly in arid and semiarid environments. Conventional breeding and biotechnological approaches are used to generate drought-tolerant crop plants. However, these techniques are costly and time-consuming. Plant-colonizing microbes, notably, endophytic fungi, have received increasing attention in recent years since they can boost plant growth and yield and can strengthen plant responses to abiotic stress. In this review, we describe these microorganisms and their relationship with host plants, summarize the current knowledge on how they “reprogram” the plants to promote their growth, productivity, and drought tolerance, and explain why they are promising agents in modern agriculture.

“…Plant hormones, including peptide hormones, are major determinants of root plasticity that bring about their effects by synergistic and antagonistic interaction between signaling networks (Matsuzaki, Yo et al ., 2010; Meng et al ., 2012; Whitford et al ., 2012; Leyser, 2018; Zhu et al ., 2020; Roy & Muller, 2022). Peptide hormones are short chains of amino acids that upon binding with their cognate cell surface receptors initiate a signal relay that ultimately controls physiological responses (Roy & Muller, 2022). The biological activity of chemically synthesized peptides predicted from genome sequences has revolutionized the field of chemical genomics.…”

SUMMARYGLV/RGF peptide encoding genes can be identified in genomes of all plants that can form roots or root-like structures suggesting they were essential for transition of plants to land.In Medicago truncatula, five of fifteen GOLVEN(GLV)/ROOT MERISTEM GROWTH FACTOR (RGF) peptide coding genes were induced during nodule organogenesis and to a varying extent under nitrogen deficiency and auxin treatment. Expression of MtGLV9 and MtGLV10 at nodule initiation sites was dependent on the transcription factor NODULE INCEPTION.Overexpression of all five nodule-induced GLV genes in M. truncatula hairy roots as well as application of the corresponding synthetic peptides resulted in a 25-50% reduction in nodule number indicating GOLVENs are negative regulators of nodule organogenesis.The peptide GOLVEN10 shifted the position of the first formed lateral root (rhizotaxis) as well as the first formed nodule along the longitudinal primary root axis, a phenomenon we term ‘nodulotaxis’, thereby reducing the absolute length of the zone of lateral organ formation on roots.Application of synthetic GOLVEN10 peptide caused an increase in cell number but not cell length in each root cortical cell layer causing an increase in root length and a consequent spatiotemporal delay in formation of the first lateral organ.Plain Language SummaryNodule positioning is an understudied trait, yet it determines the length of the root that can support nodule formation and consequently the total number of functional nodules formed. We identify for the first time, genetic factors called GOLVEN peptides that alter nodule and lateral root positioning on the primary root along with several other traits including nodule organ initiation and root architecture.
