“…The regulatory role of CEP in root growth has been investigated in cucumber, Arabidopsis, Brassica rapa L., and other plants. For example, knocking out the CEP gene in Arabidopsis resulted in increased primary root length and number of lateral roots [55,56]. Similarly, peptides such as BrCEP3 and BrCEP26 have been demonstrated to significantly enhance primary root growth in moss [57].…”

Small peptides in plants are typically characterized as being shorter than 120 amino acids, with their biologically active variants comprising fewer than 20 amino acids. These peptides are instrumental in regulating plant growth, development, and physiological processes, even at minimal concentrations. They play a critical role in long-distance signal transduction within plants and act as primary responders to a range of stress conditions, including salinity, alkalinity, drought, high temperatures, and cold. This review highlights the crucial roles of various small peptides in plant growth and development, plant resistance to abiotic stress, and their involvement in long-distance transport. Furthermore, it elaborates their roles in the regulation of plant hormone biosynthesis. Special emphasis is given to the functions and mechanisms of small peptides in plants responding to abiotic stress conditions, aiming to provide valuable insights for researchers working on the comprehensive study and practical application of small peptides.

“…Mutants defective in the CEPR1 orthologue, COMPACT ROOT ARCHITECTURE 2 (CRA2) ( Huault et al , 2014 ; Mohd-Radzman et al , 2016 ), also have reduced root N uptake ( Bourion et al , 2014 ), and MtCEP1 peptide systemically promotes MtNRT2.1 expression and nitrate uptake in a CRA2-dependent manner ( Luo et al , 2023 ). The induction of CEP genes in response to environmental stresses, such as N limitation, is also a conserved feature of CEP signalling in other plant species, including apple ( Malus×domestica ) ( Li et al , 2018 ), cucumber ( Cucumis sativus ) ( Liu et al , 2021 ), and rice ( Oryza sativa ) ( Sui et al , 2016 ).…”

A growing understanding is emerging of the roles of peptide hormones in local- and long-distance signalling that coordinates plant growth and development as well as responses to the environment. C-TERMINALLY ENCODED PEPTIDE (CEP) signalling triggered by its interaction with CEP RECEPTOR 1 (CEPR1) is known to play roles in systemic nitrogen (N)-demand signalling, legume nodulation, and root system architecture. Recent research provides further insight into how CEP signalling operates, which involves diverse downstream targets and interactions with other hormone pathways. Additionally, there is emerging evidence of CEP signalling playing roles in N-allocation, root responses to carbon levels, the uptake of other soil nutrients such as phosphorus and sulphur, root responses to arbuscular mycorrhizal fungi, plant immunity, and reproductive development. These findings suggest CEP signalling more broadly coordinates growth across the whole plant in response to diverse environmental cues. Moreover, CEP signalling and function appears to be conserved in angiosperms. In this manuscript, we review the recent advances in CEP biology with a focus on soil nutrient uptake, root system architecture and organogenesis, and roles in plant-microbe interactions. Furthermore, we address knowledge gaps and future directions in this research field.

“…(2018) found that CsGPA1 controlled root growth by promoting the cell size and meristem of cucumber tip cells through the study of G protein. CsCEP4 peptide can promote the growth of cucumber primary roots by regulating reactive oxygen species ( Liu et al., 2021 ). The amino acid transporter CsAAP2 can mediate polar auxin transport in cucumber root tip to influence root development ( Yao et al., 2023 ).…”

BackgroundThe plant root system is critical for the absorption of water and nutrients, and have a direct influence on growth and yield. In cucumber, a globally consumed crop, the molecular mechanism of root development remains unclear, and this has implications for developing stress tolerant varieties. This study sought to determine the genetic patterns and related genes of cucumber root weight. A core cucumber germplasms population was used to do the GWAS analysis in three environments.ResultsHere, we investigated four root-weight related traits including root fresh weight (RFW), root dry weight (RDW), ratio of root dry weight to root fresh weight (RDFW) and the comprehensive evaluation index, D-value of root weight (DRW) deduced based on the above three traits for the core germplasm of the cucumber global repository. According to the D-value, we identified 21 and 16 accessions with light and heavy-root, respectively. We also found that the East Asian ecotype accessions had significantly heavier root than other three ecotypes. The genome-wide association study (GWAS) for these four traits reveals that 4 of 10 significant loci (gDRW3.1, gDRW3.2, gDRW4.1 and gDRW5.1) were repeatedly detected for at least two traits. Further haplotype and expression analysis for protein-coding genes positioned within these 4 loci between light and heavy-root accessions predicted five candidate genes (i.e., Csa3G132020 and Csa3G132520 both encoding F-box protein PP2-B1 for gDRW3.1, Csa3G629240 encoding a B-cell receptor-associated protein for gDRW3.2, Csa4G499330 encodes a GTP binding protein for gDRW4.1, and Csa5G286040 encodes a proteinase inhibitor for gDRW5.1).ConclusionsWe conducted a systematic analysis of the root genetic basis and characteristics of cucumber core germplasms population. We detected four novel loci, which regulate the root weight in cucumber. Our study provides valuable candidate genes and haplotypes for the improvement of root system in cucumber breeding.
