“…The plants are also vulnerable during periods of flowering, fruit setting, and ripening [ 30 ]. Strawberry seedling growth can be enhanced by applying amendments such as melatonin under Cd stress [ 32 ], auxin application (indole-3-acetic acid; IAA) in saline soils [ 33 ], CeO 2 nanoparticles [ 34 ], nutrients such as molybdenum [ 35 ], nano-zeolite [ 36 ], nano-calcium [ 37 ], and other nanofertilizers [ 38 ], organic fertilizer after soil fumigation [ 39 ], and 5-aminolevulinic acid under salt stress [ 40 ].…”

Strawberry production presents special challenges due the plants’ shallow roots. The rooting stage of strawberry is a crucial period in the production of this important crop. Several amendments have been applied to support the growth and production of strawberry, particularly fertilizers, to overcome rooting problems. Therefore, the current investigation was carried out to evaluate the application of biological nanofertilizers in promoting strawberry rooting. The treatments included applying two different nanofertilizers produced biologically, nano-selenium (i.e., 25, 50, 75, and 100 mg L−1) and nano-copper (i.e., 50 and 100 mg L−1), plus a control (untreated seedlings). The rooting of strawberry seedlings was investigated by measuring the vegetative growth parameters (root weight, seedling weight, seedling length, and number of leaves), plant enzymatic antioxidants (catalase, peroxidase, and polyphenol oxidase activity), and chlorophyll content and its fluorescence and by evaluating the nutritional status (content of nutrients in the fruit and their uptake). The results showed that the applied nanofertilizers improved the growth, photosynthetic pigments, antioxidant content, and nutritional status of the seedlings compared to the control. A high significant increase in nutrient contents reached to more than 14-fold, 6-fold, 5-folf, and 4-fold for Cu, Mn, N, and Se contents, respectively, due to the applied nanofertilizers compared with the control. The result was related to the biological roles of both Se and CuO in activating the many plant enzymes. Comparing the Se with the CuO nanofertilizer, Cu had the strongest effect, which was shown in the higher values in all studied properties. This study showed that nanofertilizers are useful to stimulate strawberry seedling growth and most likely would also be beneficial for other horticultural crops. In general, the applied 100 ppm of biological nano-Se or nano-CuO might achieve the best growth of strawberry seedlings under growth conditions in greenhouses compared to the control. Along with the economic dimension, the ecological dimension of biological nanofertilizers still needs more investigation.

“…In our study, the amount of NO stimulated by 5-ALA should have been at the range of nontoxic doses leading to nontoxic plant metabolic events in tomato seedlings. 5-ALA-generated NO synthesis enhancing tolerance has been reported under salinity stress for strawberry [ 22 ], and maize plants [ 59 ], but no data exist for Cr stress. 5-ALA enhances plant growth and yield, as well as abiotic stress tolerance, by regulating photosynthetic and antioxidant mechanisms and plant nutrient uptake [ 60 ].…”

“…Supplementation of 5-ALA has previously been shown to enhance the tolerance of cucumbers to salinity and low-temperature stress [ 19 , 20 ], and of strawberries to osmotic stress [ 21 ]. It has been suggested that 5-ALA improves plant abiotic stress tolerance by inducing hydrogen peroxide (H 2 O 2 ) and nitric oxide (NO) signalling [ 22 ]. Recently, foliar application of 5-ALA has been suggested as a feasible alternative approach to alleviate Cr-induced stress in crop plants, but reports on the beneficial effect of 5-ALA on Cr stress in plants are rare [ 23 ].…”

Chromium [Cr(VI)] pollution is a major environmental risk, reducing crop yields. 5-Aminolevunic acid (5-ALA) considerably improves plant abiotic stress tolerance by inducing hydrogen peroxide (H2O2) and nitric oxide (NO) signalling. Our investigation aimed to uncover the mechanism of tomato tolerance to Cr(VI) toxicity through the foliar application of 5-ALA for three days, fifteen days before Cr treatment. Chromium alone decreased plant biomass and photosynthetic pigments, but increased oxidative stress markers, i.e., H2O2 and lipid peroxidation (as MDA equivalent). Electrolyte leakage (EL), NO, nitrate reductase (NR), phytochelatins (PCs), glutathione (GSH), and enzymatic and non-enzymatic antioxidants were also increased. Foliar application of 5-ALA before Cr treatment improved plant growth and photosynthetic pigments, diminished H2O2, MDA content, and EL, and resulted in additional enhancements of enzymatic and non-enzymatic antioxidants, NR activity, and NO synthesis. In Cr-treated tomato seedlings, 5-ALA enhanced GSH and PCs, which modulated Cr sequestration to make it nontoxic. 5-ALA-induced Cr tolerance was further enhanced by sodium nitroprusside (SNP), a NO donor. When sodium tungstate (ST), a NR inhibitor, was supplied together with 5-ALA to Cr-treated plants, it eliminated the beneficial effects of 5-ALA by decreasing NR activity and NO synthesis, while the addition of SNP inverted the adverse effects of ST. We conclude that the mechanism by which 5-ALA induced Cr tolerance in tomato seedlings is mediated by NR-generated NO. Thus, NR and NO are twin players, reducing Cr toxicity in tomato plants via antioxidant signalling cascades.

“…It is a smart mechanism for ALA to enhance plant stress tolerance. Furthermore, the increase of H 2 O 2 in the roots is dependent on NO production [226]. Thus, ALA signaling may be mediated by NO and/or H 2 O 2 to upregulate salt ion transport gene expressions for ion homeostasis.…”

“…Furthermore, the tissue specificity of the biosynthesis and function of H 2 O 2 and NO cannot be ignored. When strawberries were stressed by PEG 6000 [200] or salinity [225,226], ALA-induced H 2 O 2 and NO were accumulated in the roots but depressed in the leaves. Similarly, the ABA content was improved in the roots but inhibited in the leaves by exogenous ALA.…”

The review briefly introduces the natural occurrence, physicochemical properties, and biosynthesis of 5-aminolevuinic acid (ALA) and highlights a variety of applications in the planting industry and its possible mechanisms. It has been known that ALA can be used as biological pesticides, fungicides, and herbicides when the concentrations are higher than 838 mg L−1 (about 5 mmol L−1). When ALA concentrations are 100–300 mg L−1, it can be used to thin surplus flowers in the spring of orchards and promote fruit coloration before maturation. When the concentrations are lower than 100 mg L−1, especially not higher than 10 mg L−1, ALA can be used as a new plant growth regulator to promote seed germination, plant (including root and shoot) growth, enhance stress tolerance, increase crop yield, and improve product quality. In photosynthesis, ALA is involved in the regulation of the whole process. In stress tolerance, ALA induces plant preventive and protective systems through the NO/H2O2 signaling network. In secondary metabolism, ALA regulates many gene expressions encoding transcription factors or function proteins to promote anthocyanin and flavonol biosynthesis and accumulation. In general, ALA promotes plant health and robustness, reduces the use of chemical fertilizers and pesticides—which is conducive to improving the ecological environment, human production, and living conditions—and has a broad application prospect in agroforestry production. As a new plant growth regulator with multiple and powerful functions, the underlying regulatory mechanisms need more study.
