“…Polyamines are small aliphatic amines found in all living cells. Put, Spd, and Spm are major components in plants and play vital roles in plant growth, development, and stress response ( Pál et al, 2015 ; Ghosh et al, 2021 ; Gonzalez et al, 2021 ). The levels of PAs increase considerably in response to cold stress ( Amini et al, 2021 ; Jiao et al, 2021 ; Wang et al, 2021 ), and a cold-tolerant rice cultivar showed a greater accumulation of PAs than the sensitive cultivars ( Sheteiwy et al, 2017 ).…”

Low temperature is a significant factor affecting field-grown pepper. The molecular mechanisms behind peppers’ response to cold stress remain unknown. Transcriptomic and metabolomic analyses were used to investigate the responses of two pepper cultivars, XS (cold-sensitive) and GZ (cold-resistant), to cold stress; these were screened from 45 pepper materials. In this study, compared with the control group (0 h), we identified 10,931 differentially expressed genes (DEGs) in XS and GZ, 657 differentially expressed metabolites (DEMs) in the positive ion mode, and 390 DEMs in the negative ion mode. Most DEGs were involved in amino acid biosynthesis, plant hormone signal transduction, and the mitogen-activated protein kinase (MAPK) signaling pathway. Furthermore, metabolomic analysis revealed that the content of free polyamines (PAs), plant hormones, and osmolytes, mainly contained increased putrescine, spermine, spermidine, abscisic acid (ABA), jasmonic acid (JA), raffinose, and proline, in response to cold stress. Importantly, the regulation of the ICE (inducer of CBF expression)-CBF (C repeat binding factors)-COR (cold regulated) pathway by Ca2+ signaling, MAPK signaling, and reactive oxygen species (ROS) signaling plays a key role in regulating responses of peppers to cold stress. Above all, the results of the present study provide important insights into the response of peppers to cold stress, which will reveal the potential molecular mechanisms and contribute to pepper screening and breeding in the future.

“…Biochemically, the synthesis and decomposition of PAs in cells are relatively well characterized [for good reviews, refer to Wang et al (2019) and Gonzalez et al (2021) ]. The biosynthesis of PAs can be divided into two major steps ( Figure 1 ).…”

“…Regarding cellular PA-homeostasis, besides free soluble and non-covalently conjugated forms, PAs may also bind to proteins and other molecules to protect the macromolecules, regulate transporter/channel activity and gene expression, or interact with some hormones. This metabolism presentation of PAs in the plant is partially adapted from the studies by Gonzalez et al (2021) and Spormann et al (2021) .…”

Polyamine(s) (PA, PAs), a sort of N-containing and polycationic compound synthesized in almost all organisms, has been recently paid considerable attention due to its multifarious actions in the potent modulation of plant growth, development, and response to abiotic/biotic stresses. PAs in cells/tissues occur mainly in free or (non- or) conjugated forms by binding to various molecules including DNA/RNA, proteins, and (membrane-)phospholipids, thus regulating diverse molecular and cellular processes as shown mostly in animals. Although many studies have reported that an increase in internal PA may be beneficial to plant growth under abiotic conditions, leading to a suggestion of improving plant stress adaption by the elevation of endogenous PA via supply or molecular engineering of its biosynthesis, such achievements focus mainly on PA homeostasis/metabolism rather than PA-mediated molecular/cellular signaling cascades. In this study, to advance our understanding of PA biological actions important for plant stress acclimation, we gathered some significant research data to succinctly describe and discuss, in general, PA synthesis/catabolism, as well as PA as an internal ameliorator to regulate stress adaptions. Particularly, for the recently uncovered phenomenon of urea-antagonized NH4+-stress, from a molecular and physiological perspective, we rationally proposed the possibility of the existence of PA-facilitated signal transduction pathways in plant tolerance to NH4+-stress. This may be a more interesting issue for in-depth understanding of PA-involved growth acclimation to miscellaneous stresses in future studies.

“…Polyamines are regulators of many physiological processes in plants, including cellular differentiation, embryogenesis, germination, organogenesis, flower development, pollen germination and growth, fruit maturation and delayed senescence (Anwar et al, 2019;Benkő et al, 2020;Mattoo and Sobieszczuk-Nowicka, 2018;Mustafavi et al, 2018;Pagano et al, 2019;Takahashi and Kakehi, 2010). In addition, PAs exert crucial roles in the abiotic and biotic stress responses that have been well documented in literature reviews (Alcázar et al, 2010;Chen et al, 2019;Gill and Tuteja, 2010;Gonzalez et al, 2021;Jiménez-Bremont et al, 2014;Minocha et al, 2014;Paschalidis et al, 2019;Tsaniklidis et al, 2020). Due to its biological implications, PA metabolism is subjected to a finetuned regulation.…”
