“…After seed germination, in roots CLE25 is expressed in the SPSC located adjacent to the QC and in descendent phloem lineage cells, and in stems CLE25 is expressed in developing SEs, and cambial cells adjacent to the SEs. The expression of CLE25 partially overlaps with its closest homolog, CLE26 , in the phloem lineage cells, although CLE26 is not expressed in the protophloem initiation zone (Czyzewicz et al 2015; Anne et al 2018). This expression pattern may need to be re‐examined, given that only the 5′ regulatory element was used in the pCLE26:NLS‐3xVENUS reporter construct (Czyzewicz et al 2015; Anne et al 2018).…”

“…CLE45 as a negative regulator suppresses phloem differentiation through BARELY ANY MERISTEM 3 (BAM3)‐CLV2/CRN‐mediated signaling pathway (Depyte et al 2013; Hazak et al 2017). CLE25 and CLE26 , two closely homologous CLE genes expressed in phloem (Czyzewicz et al 2015; Anne et al 2018), deliver a long‐distance drought signal from root to shoot (Takahashi et al 2018) and regulate lateral root formation (Czyzewicz et al 2015), respectively.…”

The phloem, located within the vascular system, is critical for delivery of nutrients and signaling molecules throughout the plant body. Although the morphological process and several factors regulating phloem differentiation have been reported, the molecular mechanism underlying its initiation remains largely unknown. Here, we report that the small peptide‐coding gene, CLAVATA 3 (CLV3)/EMBEYO SURROUNDING REGION 25 (CLE25), the expression of which begins in provascular initial cells of 64‐cell‐staged embryos, and continues in sieve element‐procambium stem cells and phloem lineage cells, during post‐embryonic root development, facilitates phloem initiation in Arabidopsis. Knockout of CLE25 led to delayed protophloem formation, and in situ expression of an antagonistic CLE25G6T peptide compromised the fate‐determining periclinal division of the sieve element precursor cell and the continuity of the phloem in roots. In stems of CLE25G6T plants the phloem formation was also compromised, and procambial cells were over‐accumulated. Genetic and biochemical analyses indicated that a complex, consisting of the CLE‐RESISTANT RECEPTOR KINASE (CLERK) leucine‐rich repeat (LRR) receptor kinase and the CLV2 LRR receptor‐like protein, is involved in perceiving the CLE25 peptide. Similar to CLE25, CLERK was also expressed during early embryogenesis. Taken together, our findings suggest that CLE25 regulates phloem initiation in Arabidopsis through a CLERK‐CLV2 receptor complex.

“…They are legume specific and appear to be most similar to CLE peptides of Arabidopsis thaliana that act in root or shoot development (Ito et al, ; Miyawaki, Tabata, & Sawa, ). CLE peptides also play key roles in nutrient responses (Czyzewicz et al, ; de Bang et al, ; Funayama‐Noguchi, Noguchi, Yoshida, & Kawaguchi, ; Handa et al, ), including a nitrogen‐responsive CLE peptide of legumes that acts to regulate nodule numbers in the nitrate regulation of nodulation pathway (outlined in detail below; Reid, Ferguson, & Gresshoff, ).…”

Global demand to increase food production and simultaneously reduce synthetic nitrogen fertilizer inputs in agriculture are underpinning the need to intensify the use of legume crops. The symbiotic relationship that legume plants establish with nitrogen-fixing rhizobia bacteria is central to their advantage. This plant-microbe interaction results in newly developed root organs, called nodules, where the rhizobia convert atmospheric nitrogen gas into forms of nitrogen the plant can use. However, the process of developing and maintaining nodules is resource intensive; hence, the plant tightly controls the number of nodules forming. A variety of molecular mechanisms are used to regulate nodule numbers under both favourable and stressful growing conditions, enabling the plant to conserve resources and optimize development in response to a range of circumstances. Using genetic and genomic approaches, many components acting in the regulation of nodulation have now been identified. Discovering and functionally characterizing these components can provide genetic targets and polymorphic markers that aid in the selection of superior legume cultivars and rhizobia strains that benefit agricultural sustainability and food security. This review addresses recent findings in nodulation control, presents detailed models of the molecular mechanisms driving these processes, and identifies gaps in these processes that are not yet fully explained.

“…Several peptide families are involved (directly or indirectly) in regulating aspects of root development, including members from CEP, RALF, RGF/GLV/CLEL, CLE, and IDL families (Figure 4). In addition to an important role in vascular development and in agreement with their presence in a wide range of plant species (see above), CLE peptides also regulate root development and rootassociated processes in various plant species (30,53,99,116,135,175). RGF/GLV/CLEL genes have key roles in root meristem maintenance (108,111) and were identified in several species with well-developed root systems (180,209).…”

“…(Changes may still occur before final publication.) peptide can result in phenotypes coming from unspecific signaling through nonnative receptors (19,30,177). Subsequently, forward or reverse genetic approaches can be employed to identify genes encoding candidate receptors (or other signaling components) for the peptide of interest, either through genetic interaction studies or insensitivity of the receptor mutant to the (synthetic) peptide (4,18,19,27,108,120,133,153,184,209) (Figure 2a) ( Table 1).…”

During the past decade, a flurry of research focusing on the role of peptides as short- and long-distance signaling molecules in plant cell communication has been undertaken. Here, we focus on peptides derived from nonfunctional precursors, and we address several key questions regarding peptide signaling. We provide an overview of the regulatory steps involved in producing a biologically active peptide ligand that can bind its corresponding receptor(s) and discuss how this binding and subsequent activation lead to specific cellular outputs. We discuss different experimental approaches that can be used to match peptide ligands with their receptors. Lastly, we explore how peptides evolved from basic signaling units regulating essential processes in plants to more complex signaling systems as new adaptive traits developed and how nonplant organisms exploit this signaling machinery by producing peptide mimics.
