“…Plant peptides can be mainly divided into the precursor-derived and nonprecursor-derived peptides (Tavormina et al, 2015). Most of the plant peptides already studied are derived from precursor proteins (Brito et al, 2018). Similarly, we observed that the most of peptides were derived from the precursor proteins in tobacco in this study.…”

Seed vigor of tobacco (Nicotiana tabacum L.) is established during seed development stage, while its regulators remain largely unknown. Here, a comparative peptidomics analysis of the developing seeds was conducted to reveal the regulators involving the establishment of tobacco seed vigor. The most significant difference of seed vigor was observed between seeds harvested at 20 and 30 days after pollination (DAP), and then the corresponding seeds were collected separately for peptidomics analysis. A total of 2932 and 2812 nonredundant peptides were identified in seeds harvested at 20 and 30 DAP, respectively. In which, 349 differentially expressed peptides (DEPs) were characterized. To explore the potential functions of these DEPs, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were further analyzed according to their precursor proteins. Most DEP precursor proteins were involved in response to abiotic stimulus, response to water, and protein processing in endoplasmic reticulum. Further, the peptides derived from the precursor proteins, such as late embryogenesis abundant (LEA) protein, heat shock protein, peroxiredoxin, and globulin proteins, may regulates the establishment of seed vigor by influencing reactive oxygen species. The results provide a foundation for further exploration of the peptides functions on the establishment of seed vigor in tobacco.

“…Interestingly, homologues of AtZSP1 have been found in soybean, maize, Setaria italica (Foxtail millet), and Brassica rapa (Chinese cabbage), indicating a conserved function for this small peptide in plants (Orr et al 2020 ). In contrast, the nonsecreted small peptide SPICE negatively affects pistil size by mediating cell expansion in tobacco (Brito et al 2018 ).…”

Small peptides represent a subset of dark matter in plant proteomes. Through differential expression patterns and modes of action, small peptides act as important regulators of plant growth and development. Over the past 20 years, many small peptides have been identified due to technical advances in genome sequencing, bioinformatics, and chemical biology. In this article, we summarize the classification of plant small peptides and experimental strategies used to identify them as well as their potential use in agronomic breeding. We review the biological functions and molecular mechanisms of small peptides in plants, discuss current problems in small peptide research and highlight future research directions in this field. Our review provides crucial insight into small peptides in plants and will contribute to a better understanding of their potential roles in biotechnology and agriculture.

“…Unlike for animals, only a few examples of functional SEPs have been described in plants. They have been shown to regulate plant programmed cell death (Blanvillain et al, 2011), root growth and development (Casson et al, 2002; Chen et al, 2020), cell proliferation and expansion (Brito et al, 2018; Ikeuchi et al, 2011), nodule formation (Rohrig et al, 2002), and pollen germination (Dong et al, 2013).…”

Recent evidence shows that small open reading frame (smORF; <100 codons)-encoded peptides (SEPs) containing transmembrane domains are preadapted to be progenitors of novel functional genes. A dozen of such SEPs translated from long non-coding RNAs (lncRNAs) are already functionally characterised in animals. However, functional plant lncRNA-smORF-coded peptides are not yet described. Here, we report detailed functional characterization of a 41-aa peptide encoded by lncRNA-smORFs in the moss Physcomitrium patens, which was named “FAst-growing MOSS” (FAMOSS). We found that the FAMOSS interacts with the Rab-type small GTPase proteins and its overexpression leads to faster moss growth rate and more intensive vesicular transport in apical cells, while its knockout results in the opposite effect. The FAMOSS contains a predicted transmembrane domain and possible orthologs from streptophyta algae to flowering plants have a very conserved structure. Thus, the FAMOSS peptide is a previously unknown conserved player of Rab-mediated processes in plants. Our findings are in line with functional studies of transmembrane SEPs in animals and prove the principles of SEPs evolution. This study provides new insights into functions of plant lncRNA-smORFs.
