The Effects of Plant Growth-Promoting Bacteria with Biostimulant Features on the Growth of a Local Onion Cultivar and a Commercial Zucchini Variety

The reduction of chemical inputs due to fertilizer and pesticide applications is a target shared both by farmers and consumers in order to minimize the side effects for human and environmental health. Among the possible strategies, the use of biostimulants has become increasingly important as demonstrated by the fast growth of their global market and by the increased rate of registration of new products. In this work, we assessed the effects of five bacterial strains (Pseudomonas fluorescens Pf4, P. putida S1Pf1, P. protegens Pf7, P. migulae 8R6, and Pseudomonas sp. 5Vm1K), which were chosen according to their previously reported plant growth promotion traits and their positive effects on fruit/seed nutrient contents, on a local onion cultivar and on zucchini. The possible variations induced by the inoculation with the bacterial strains on the onion nutritional components were also evaluated. Inoculation resulted in significant growth stimulation and improvement of the mineral concentration of the onion bulb, induced particularly by 5Vm1K and S1Pf1, and in different effects on the flowering of the zucchini plants according to the bacterial strain. The present study provides new information regarding the activity of the five plant growth-promoting bacteria (PGPB) strains on onion and zucchini, two plant species rarely considered by the scientific literature despite their economic relevance.

“…Selenium plays a crucial role in the protection of plants from the toxic impacts of metals/metalloids (Feng et al, 2020;Riaz et al, 2021). It is a common phenomenon that plants under the exposure of metals/metalloids tend to reduce their growth.…”

Selenium Supplementation and Crop Plant Tolerance to Metal/Metalloid Toxicity

Selenium (Se) supplementation can restrict metal uptake by roots and translocation to shoots, which is one of the vital stress tolerance mechanisms. Selenium can also enhance cellular functions like membrane stability, mineral nutrition homeostasis, antioxidant response, photosynthesis, and thus improve plant growth and development under metal/metalloid stress. Metal/metalloid toxicity decreases crop productivity and uptake of metal/metalloid through food chain causes health hazards. Selenium has been recognized as an element essential for the functioning of the human physiology and is a beneficial element for plants. Low concentrations of Se can mitigate metal/metalloid toxicity in plants and improve tolerance in various ways. Selenium stimulates the biosynthesis of hormones for remodeling the root architecture that decreases metal uptake. Growth enhancing function of Se has been reported in a number of studies, which is the outcome of improvement of various physiological features. Photosynthesis has been improved by Se supplementation under metal/metalloid stress due to the prevention of pigment destruction, sustained enzymatic activity, improved stomatal function, and photosystem activity. By modulating the antioxidant defense system Se mitigates oxidative stress. Selenium improves the yield and quality of plants. However, excessive concentration of Se exerts toxic effects on plants. This review presents the role of Se for improving plant tolerance to metal/metalloid stress.

“…Exposure of plants to metal stress often lead to injurious effects on growth parameters, particularly plants biomass. Although the adverse effects of excessive metal ions vary in plant species, genotypes and even in plant tissues ( Riaz et al, 2021 ). Both fresh and dry biomass are considered as sensitive parameters and potential indicator that reflect cumulative expression to determine the plant’s response towards metals toxicity ( Alamri et al, 2018 ).…”

“…Pb has been widely reported to alter plant responses at different stages of development because it induces changes in metabolic pathways involved in the biosynthesis of all types of fundamental macromolecules (carbohydrates, lipids and proteins), activities of enzymes and stability of biological membranes ( Jian et al, 2020 , Gao et al, 2021 ). In some plant species, even minute quantity of Pb in the growth medium can cause cell death ( Riaz et al, 2021 ). Although, the responses of plant species at inter and intra-specific levels vary greatly for heavy metals ( Sofy et al, 2020 ).…”

Highlights The growth, biosynthesis of pigments and other macromolecules appeared to be strong predictors in appraisal of Pb tolerance/susceptibility in durum wheat. Germplasm of CBD59, CBD63 and CBD66 can be exploited for future selection and breeding programs. The bioaccumulation of metal in grains of some cultivars of durum wheat much below than permissible limits set by FAO/WHO is of great significance owing to its implications for food safety.
