“…Ethylene (400 µM) can enhance plant tolerance potential to Cu toxicity by alleviating Cu-induced poisonous effects [49]. Additionally, ethylene responsive factors (AP2/ERF) overexpression is reported for the activation of phytohormonal crosstalk by accumulation of JA, linolenic acid, ABA and their biosynthesis genes in rice [50]. Moreover, plasma membrane H + -ATPases are considered crucial for modulating abiotic stress including heavy metal responses in plants.…”

Rice (Oryza sativa) is a research model for monocotyledonous plants. Rice is also one of the major staple foods and the primary crop for more than half of the world’s population. Increasing industrial activities and the use of different fertilizers and pesticides containing heavy metals (HMs) contribute to the contamination of agriculture fields. HM contamination is among the leading causes that affect the health of rice plants by limiting their growth and causing plant death. Phytohormones have a crucial role in stress-coping mechanisms and in determining a range of plant development and growth aspects during heavy metal stress. This review summarizes the role of different exogenous applications of phytohormones including auxin, cytokinin, gibberellins, ethylene, abscisic acid, strigolactones, jasmonates, brassinosteroids, and salicylic acids in rice plants for mitigating heavy metal stress via manipulation of their stress-related physiological and biochemical processes, and alterations of signaling and biosynthesis of genes. Exogenous administration of phytohormones and regulation of endogenous levels by targeting their biosynthesis/signaling machineries is a potential strategy for protecting rice from HM stress. The current review primarily emphasizes the key mechanistic phytohormonal-mediated strategies for reducing the adverse effects of HM toxicity in rice. Herein, we have provided comprehensive evidence for the effective role of exogenous phytohormones in employing defense responses and tolerance in rice to the phytotoxic effects of HM toxicity along with endogenous hormonal crosstalk for modulation of subcellular mechanisms and modification of stress-related signaling pathways, and uptake and translocation of metals. Altogether, this information offers a systematic understanding of how phytohormones modulate a plant’s tolerance to heavy metals and may assist in directing the development of new approaches to strengthen rice plant resistance to HM toxicity.

“…Using the bioproducts that are safe for people and environment might solve numerous problems in the production of field crops. For example, it can facilitate the growth and development of plants, stimulate the formation of flowers and seeds, accelerate maturation, increase the yield and quality of agricultural produce, and enhance non-specific resistance to many diseases of various origin [7][8].…”

The paper presents the results of a study on the influence of bioproducts on soybean plants under the conditions of Primorsky kray. The research was carried out as a microplot experiment in 2020-2022. Bioproducts and soybean variety Primorskaya 86 served as the research object. The highest biological efficacy against Septoria blight (21.4%) was detected in the variant with a complex treatment with bioproduct Gamair. All of the studied bioproducts were equally effective against downy mildew (32 %). The bioproducts increased plant density and preservation until harvest. The highest plant density was observed in the variant with seed treatment and foliage spraying with Baktofit (60.3 plants/m2). The highest degree of preservation was detected after seed treatment with Biocomposite-correct (93.2 plants/m2). The plant height in the experimental variants exceeded the standard by 9.3-16.8 cm. A tendency for the growth of soybean herbage and roots was observed in the variant with a complex treament with Biocomposite-correct, which exceeded the control by 29.4 and 28.9%, respectively. The TKW increased by 10.1-26.0 % after treatment with the studied bioproducts. The seed weight per plant was by 10.5-51.1% higher in the experimental variants than in the control. Using the bioproducts allowed a significant gain in yield from 0.4 to 1.3 t/ha. The highest yield (3.8 t/ha) was observed in the variants with the treatment of seeds with Biocomposite-correct and the seed treatment with any bioproduct followed by subsequent spraying of foliage during the growing period with the same bioproduct.

“…Phytohormones are known as essential components of signaling cascades in plant growth and responses to various abiotic and biotic stresses (Kumar 2013). These compounds can be classified according to their chemical structure including auxin, gibberellin (GA), cytokinin, abscisic acid (ABA) and ethylene (ET) as "classic phytohormones", and a newly emerging family including brassinosteroid (BR), jasmonate (JA), salicylate (SA), strigolactone (SL), nitric oxide (NO), polyamine and peptide groups (Wang et al 2019). Basic developmental processes such as cell division, enlargement and differentiation, organ formation, seed dormancy and germination, leaf and organ senescence and abscission are triggered by minute quantities of plant hormones (Shan et al 2012).…”

Destruction caused by plant diseases is terrible. Mexican lime witches' broom (MLWB) is a phytoplasma disease, which has caused considerable damage in Mexican lime tree in southern parts of Iran. In order to protect the plant against this pathogen, it is required to apply an appropriate treatment to induce resistance. Moreover, for better comprehension of disease mechanism, the analysis of phytohormones as one of the most critical basic components in plant cells, probably involved in resistance mechanisms, is of great importance. In this work, Mexican lime trees infected with lime witches'-broom phytoplasma (LWBP) were treated with Previcur Energy Tm (31% fosetyl-Alluminum plus 53% propamocarb) 4/ 000 as the resistance inducer against phytoplasma. In the next step, phytohormone levels in healthy Mexican lime were compared with those of infected and treated lime trees. For analysis of phytohormones, one-step dispersive solid phase extraction (DSPE) combined with liquid chromatography-tandem mass spectrometry-multiple reaction monitoring (LC-MS/MS-MRM) mode was used. A total of 54 phytohormones including cytokinins, auxins, jasmonates, gibberellins, salicylic acid and abscisic acid groups were simultaneously analyzed for treated, infected, and healthy plants. Totally, 18 phytohormones from plant leave extract were detected, among which levels of 11 phytohormones including SA, JA, JA-Phe, JA-Ile, JA-Leu, OPDA, CZ, iP7G, cZ9G, TZr and 2MeStZR were significantly changed in both infected and treated plants. Result of the present study indicated that the applied treatment was able to reduce the severity score in plant. On the other hand, phytoplasma (as a biotic stress) and treatment with Previcur Energy Tm (as a resistance inducer) could affect fundamental processes in plant via regulation of phytohormone levels.
