“…This model may be ubiquitous because similar root interception of the salt ion has been reported in cucumber [147] and Arundo donax [166], where the NHX1 and VHA-A (encoding H + -ATPase in tonoplast) expressions were upregulated by ALA in cucumber roots under salinity [147]. Additionally, ALA-induced arsenic interception in the vacuoles of pepper roots is also reported [218], although whether any transcription factor is involved in regulation is not clear. Even though it should be an important mechanism for ALA to induce detoxication of harmful elements when plants encounter chemical stresses.…”

“…Arsenic (As), one of the dangerous metalloids, is regularly encountered by the environment due to human activity and environmental practices such as mining, widespread use of pesticides and fertilizers, burning fossil fuels, and increased deposition of municipal and industrial garbage. Recently, ALA was found to alleviate arsenic toxicity in pepper plants by modulating its sequestration and distribution within cell organelles of the roots [218]. Heme, converted from ALA, was considered an important regulator for the increase of antioxidant systems and cellular arsenic detoxification.…”

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.

“…[1][2][3] Arsenic in groundwater can exist in inorganic and organic forms, with the inorganic As showing higher toxicity. [4][5][6] Generally, inorganic As primarily exists as either As(III) or As(V), and As(III) is more toxic and mobile. 7 Under reducing groundwater conditions, arsenite or H 3 AsO 3 is the main form of As(III) when the pH is near-neutral.…”

Enhancing crop drought tolerance is crucial for food security amid climate change. This study examines how 5‐aminolevulinic acid (ALA) and hydrogen sulfide (H2S) can improve drought resilience in tomato plants, which are essential for sustainable food production. Drought stress was induced using 12% PEG‐6000. Plants were pre‐treated with 25 mg L−1 ALA and 0.1 mg L−1 hypotaurine (HT), followed by 0.2 mM sodium hydrosulfide (NaHS) treatment to assess the effects on plant physiological effects over 10 days. Drought stress reduced plant dry weight, chlorophylls (a and b), Fv/Fm, leaf water potential, and relative water content, while increasing glycine betaine (GB) and proline levels. Additionally, drought stress elevated NADPH oxidase (NOX) and glycolate oxidase (GOX) activities, inducing oxidative stress and membrane damage. ALA and NaHS enhanced plant growth, photosynthesis, proline, GB, ALA content, ATP synthase, and ATPase activities, while mitigating NOX and GOX activities, thereby reducing and H2O2 radicals. ALA alone boosted L‐DES activity, promoting H2S accumulation. However, ALA + HT reduced H2S levels, compromising ALA's efficacy. NaHS with ALA + HT reinstated positive effects by restoring H2S levels. Biochemical assays confirmed ALA and NaHS promoted H2S accumulation, bolstering antioxidants, mitigating lipid peroxidation, suggesting their drought resilience potential in tomatoes.
