“…The PA spermidine has been reported to regulate mitochondrial reactive oxygen species (ROS) homeostasis in G. lucidum ( 3 ). PAs indirectly activate metabolite production by stimulating different signaling pathways as a part of the stress reversal process ( 4 ). In research on cucumber, foliar application of Put can alleviate the stomatal closure and photosynthesis decline caused by salt stress and promote cucumber growth ( 5 ).…”

“…Among the treatments, a concentration of 50 mg•L −1 PU individually or with 250 mg•L −1 BAP interactively would be recommended as the pre-eminent treatments. The renowned polyamines are PU, spermidine, and spermine (Nandy et al 2022). Among them, PU is plentiful in leaves and has unique functions in plant growth and development (González-Hernández et al 2022).…”

“…Among them, PU is plentiful in leaves and has unique functions in plant growth and development (González-Hernández et al 2022). Over the last decade, PUs have been introduced as a novel plant biostimulant (phytostimulator) due to having a group of low-molecular-weight, organic, aliphatic, polycationic, and amine molecules that are classified as PGRs (Nandy et al 2022). Polyamines are reported to have constructive contributions within gene expression, DNA replication, cell division and differentiation, protein synthesis, and enzyme activity (Mustafavi et al 2018).…”

Sternbergia clusiana (SC) is a bulbous plant having an alluring ornamental flower, medicinal properties, and an endangered status due to climate-change ecology. However, the methods of propagation for conserving this notable species have been neglected. The main aim of this study was to evaluate the influence of plant growth regulators (PGRs) on SC regeneration by virtue of an asexual propagation method, with the intention of preserving this endangered species from extinction. In this regard, having collected the bulbs from a wild habitat, bulbs were cut in accordance with the chipping technique. Thereafter, pieces were treated with 6-benzylaminopurine (BAP) at 250, 500, and 1000 mg L-1, 1-naphthaleneacetic acid (NAA), at 100, 250, and 500 mg L-1, putrescine (PU) at 50, 100, and 200 mg L-1, BAP and NAA combination, BAP and PU combination, and a control. Pieces were then transferred into primary and terminal growing media under laboratory and greenhouse conditions, respectively. Next, the number, length, width, and weight of bulbs were determined. The greatest bulb number (2.10 count), bulb length (26.75 mm), bulb width (16.25 mm), and bulb weight (3.13 g) were observed in the PU treatments. In addition, the results showed that even though the treated bulbs with BAP and PU combinations had preferable performance generally, the results were inconsistent. Taken together, this research indicates that utilizing asexual propagation along with PGRs, in the proper dosage, can serve as a mechanism to protect the endangered geophyte from extinction in nature.

“…Polyamines alleviate drought in plants by modulating the leaf water status and photosynthesis, as well as their polycationic nature allows them to stabilize their thylakoid membranes through chaperone activity [ 85 ]. During polyamine catabolism, large amounts of signaling molecules such as NO and H 2 O 2 are produced, which are pivotal in stomatal movement and closure, preventing water loss during drought and influencing redox balance and antioxidant system improvement [ 86 , 87 , 88 ].…”

The drought sensitivity of the pedunculate oak (Quercus robur L.) poses a threat to its survival in light of climate change. Mycorrhizal fungi, which orchestrate biogeochemical cycles and particularly have an impact on the plant’s defense mechanisms and metabolism of carbon, nitrogen, and phosphorus, are among the microbes that play a significant role in the mitigation of the effects of climate change on trees. The study’s main objectives were to determine whether ectomycorrhizal (ECM) fungi alleviate the effects of drought stress in pedunculate oak and to investigate their priming properties. The effects of two levels of drought (mild and severe, corresponding to 60% and 30% of field capacity, respectively) on the biochemical response of pedunculate oak were examined in the presence and absence of ectomycorrhizal fungi. To examine whether the ectomycorrhizal fungi modulate the drought tolerance of pedunculate oak, levels of plant hormones and polyamines were quantified using UPLC-TQS and HPLC-FD techniques in addition to gas exchange measurements and the main osmolyte amounts (glycine betaine-GB and proline-PRO) which were determined spectrophotometrically. Droughts increased the accumulation of osmolytes, such as proline and glycine betaine, as well as higher polyamines (spermidine and spermine) levels and decreased putrescine levels in both, mycorrhized and non-mycorrhized oak seedlings. In addition to amplifying the response of oak to severe drought in terms of inducible proline and abscisic acid (ABA) levels, inoculation with ECM fungi significantly increased the constitutive levels of glycine betaine, spermine, and spermidine regardless of drought stress. This study found that compared to non-mycorrhized oak seedlings, unstressed ECM-inoculated oak seedlings had higher levels of salicylic (SA) and abscisic acid (ABA) but not jasmonic acid (JA), indicating a priming mechanism of ECM is conveyed via these plant hormones. According to a PCA analysis, the effect of drought was linked to the variability of parameters along the PC1 axe, such as osmolytes PRO, GB, polyamines, and plant hormones such as JA, JA-Ile, SAG, and SGE, whereas mycorrhization was more closely associated with the parameters gathered around the PC2 axe (SA, ODPA, ABA, and E). These findings highlight the beneficial function of the ectomycorrhizal fungi, in particular Scleroderma citrinum, in reducing the effects of drought stress in pedunculate oak.
