“…İD İD Vijayakumari et al, 2016), chitosan (Rashidi et al, 2020), salicylic acid (Hayat et al, 2010) and many other known and newly identified compounds (Valluru et al, 2016;Ashour et al, 2021;Sheikhalipour et al, 2021;Ayed et al, 2022) are reported to enhance growth, development and stress tolerance levels in crops. Therefore, priming, foliar spraying, or other external field applications of these compounds are of great importance for agricultural sustainability (Singh et al, 2015;Pawar and Laware, 2018;Zulfiqar, 2021).…”

“…There have been several studies and applications to enhance salt stress tolerance in tomato (Cuartero and Fernandez-Munoz, 1999;Ashraf and Harris, 2004;Flowers, 2004;Foolad, 2004;Mayak et al, 2004;Munns, 2011;Shahbaz et al, 2012;Machado and Serralheiro, 2017), however, there is still a significant need for practical applications to reduce or eliminate the destructive effects of salt stress on tomato production. Foliar application of biostimulants would be an easy and cheap strategy to mitigate stress levels on crops (Ayed et al, 2022). Therefore, this study aimed to 1) evaluate the effect of chitosan foliar spraying on growth and development, and 2) the physiological parameters of tomato (S. lycopersicum L.) under salt-stressed conditions.…”

Environmental and climatic fluctuations as well as abiotic stress factors affect agricultural production and cause a loss in quality and yield. It is important to find alternative solutions for the sustainability of agricultural production to feed the increasing population. Salt stress is one of the most devastating abiotic stress factors and tomato production is also affected by salt stress since it needs extensive irrigation for high yield. The exogenous application of some plant inducers showed promising results in the induction and improvement of plant tolerance to stress factors. Chitosan (2-amino-2-deoxy-b-D-glucosamine), one of the organic compounds, is getting significant attention in agriculture with its potential. Here, we evaluated the potential of chitosan application for salt stress tolerance on tomato. 0.03% and 0.05% chitosan solutions were applied as a foliar spray to the plant and salt tolerance improvement were investigated under untreated (0 mM NaCl) and 100 mM NaCl conditions. The growth-related (root and shoot diameters, above and below-ground biomass, number of leaves and branches, and plant height), photosynthetic parameters (chlorophyll a, b, total carotenoid content), and ion leakage were investigated. According to the results, chitosan application improves plant development in both untreated and salt-stress conditions and improved plant growth. Also, photosynthetic parameters showed that the application of chitosan increased chlorophyll contents under untreated conditions. Our result suggests that the application of chitosan may have a promising effect on salt stress tolerance and further research may shed light on its molecular mechanisms.

“…Over the time, various researchers have classified biostimulants into nine broad categories including seaweeds and plant extracts, complex organic materials (obtained from sewage sludge extracts, composts, manure urban and agro-industrial waste products), humic substances, antitranspirants (kaolin and polyacrylamide), chitin and chitosan derivatives, elements (Al, Co, Se, Na, and Si), hydrolyzed proteins, nitrogen-containing compounds and microbial inoculants ( Colla and Rouphael, 2020 ; Teklić et al., 2021 ; Franzoni et al., 2022 ; Monteiro et al., 2022 ). Out of this wide category, microbial-based biostimulants including plant growth-promoting bacteria ( Bacillus, Serratia, Arthrobacter, Pseudomonas, Rhodococcus, Enterobacter, Ochrobactrum, Acinetobacter, Azospirillum, Rhizobium, Streptomyces and Stenotrophomonas ) have surfaced as highly valuable and inexpensive agricultural input for improving plant yield ( Orozco-Mosqueda et al., 2020 ; Baltazar et al., 2021 ; Miceli et al., 2021 ; Ayed et al., 2022 ; Fadiji et al., 2022 ). These microbiome based biostimulants trigger plant growth through solubilization of minerals (Zn, P and K), nitrogen fixation, production of phytohormones like indole-3-acetic acid (IAA), abscisic acid (ABA), ethylene (ET), cytokinin (CK), jasmonic acid (JA), secondary metabolites (siderophores, N-acyl homoserine lactone, lipopeptides, rhamnolipids, cyclic lipopeptides), enzymes (chitinases, cellulose, protease, glucanase etc.…”

Increased food production to cater the need of growing population is one of the major global challenges. Currently, agro-productivity is under threat due to shrinking arable land, increased anthropogenic activities and changes in the climate leading to frequent flash floods, prolonged droughts and sudden fluctuation of temperature. Further, warm climatic conditions increase disease and pest incidences, ultimately reducing crop yield. Hence, collaborated global efforts are required to adopt environmentally safe and sustainable agro practices to boost crop growth and productivity. Biostimulants appear as a promising means to improve growth of plants even under stressful conditions. Among various categories of biostimulants, microbial biostimulants are composed of microorganisms such as plant growth-promoting rhizobacteria (PGPR) and/or microbes which stimulate nutrient uptake, produce secondary metabolites, siderophores, hormones and organic acids, participate in nitrogen fixation, imparts stress tolerance, enhance crop quality and yield when applied to the plants. Though numerous studies convincingly elucidate the positive effects of PGPR-based biostimulants on plants, yet information is meagre regarding the mechanism of action and the key signaling pathways (plant hormone modulations, expression of pathogenesis-related proteins, antioxidants, osmolytes etc.) triggered by these biostimulants in plants. Hence, the present review focuses on the molecular pathways activated by PGPR based biostimulants in plants facing abiotic and biotic challenges. The review also analyses the common mechanisms modulated by these biostimulants in plants to combat abiotic and biotic stresses. Further, the review highlights the traits that have been modified through transgenic approach leading to physiological responses akin to the application of PGPR in the target plants.

“…Currently, Brazil is considered the largest producer of soybeans, with an estimated production for 2023 of 151. 5 Considering the signi cant representation of soybeans, phytotechnical studies are necessary to enhance its productivity, and seedling vigor is important characteristic in the formation for production stand. In this sense, seeds treatment with biostimulant or biofertilizer products is a promising practice, as it contributes to seed physiology, stimulating germination, emergence and vigor of seedlings (Silva et In Brazil, Ministry of Agriculture and Livestock published Decree No.…”

Seeds treatment with biostimulants for soybean is a promising practice, but there are little studies regarding protocols of bioinputs, such as Ascophyllum nodosum L. seaweed extract. We aimed to evaluate the effect of doses of A. nodosum on soybean seeds treatment, and its impact on germination and seedling vigor. Two tests were conducted, i) germination and seedlings vigor, and ii) emergence and photochemical processes in the field. Six doses of A. nodosum extract (ANE) were tested: 0, 1, 2, 3, 4, and 5 mL kg seeds−1, whose seeds were packed in plastic packaging, adding the corresponding dose and homogenizing, leaving them to rest for 15 minutes. ANE treatment did not influence the first count and seed germination. Soybean seedlings from seeds treated with 5 mL kg−1 ANE had greater growth and biomass of the shoot and root. We observed increase 18% for shoot dry matter with seeds treatment of 5 mL kg−1 ANE compared to untreated seeds. The responses were variable for the emergence speed index, and did not influence the photochemical processes in photosystem II in function at ANE, while the seeds treated with ANE had higher chlorophyll index. In cluster analysis seeds treatment with 5 mL kg−1 ANE was isolated from all doses. ANE presented a biostimulant effect on soybean seedlings, providing better growth and biomass characteristics, being promising in seeds treatment, but further studies are suggested in order to increase information regarding its use protocol for soybeans.
