“…(PKS1), Serratia proteamaculans (S1BD1) and Pseudomonas sp. (PFS1 and BSS3B2) (Xia et al 2020), on wheat and salt grass under the influence of salt-induced stress showed drastic reduction in the salt content of the soil. Nevertheless, there was also visible increase in osmolytes (sugar and proline) in the presence of AMF -Claroideoglomus claroideum (BEG210) and Pseudomonas libanensis (TR1) (Ma et al 2019) with phenotypic changes in shoot length, dry weight, and the yield of plants compared to their controls (Table 1).…”

One of the most serious threats facing agricultural productivity in the world is unfavourable soil conditions. Several studies have shown that almost half of the world’s land-mass is affected by either natural or human-induced pollution. This, therefore, poses a threat to agricultural improvement needed to tackle the problem of a continuous increase in the world population. The emergence of soil extremophiles with plant growth-promoting trait has proven to be a reliable means to quell the threat posed by some factors limiting soil potency. Adopting these organisms as bio-inoculants will easily proffer a solution to both biotic and abiotic soil stress. As such, the natural bio-fertilisers will help to improve the quality of the soil by making it healthy enough to sustain sufficient plant growth. This review gives an overview of the multifarious importance of extremophiles on plants grown under harsh soil conditions, with the multifaceted application of omics as a means to unveil these organisms and their benefits for environmentally sustainable agricultural systems and food safety.

“…The PGP microorganisms perform several functions, such as phosphate solubilisation, production of phytohormones (e.g., cytokinins CK, gibberellins GA, and indole-3acetic acid IAA) and siderophores, nitrogen fixation, and 1-aminocyclopropane-1carboxylic acid (ACC) deaminase synthesis (Płociniczak et al 2017). As a result, these microorganisms have been used as inocula to boost plant growth, reduce contaminant-induced stress, and stimulate degradation of TPH by rhizosphere microorganisms (Kuo et al 2014;Xia et al 2020;Xun et al 2015).…”

Highlights • Recalcitrant fractions of petroleum hydrocarbon (TPH) cometabolized for remediation • Biostimulation provides propitious environment for degraders in the rhizosphere • Bioaugmentation can supplement the catabolic activities of rhizosphere communities • Effective rhizoremediation requires the modulation of plant-microbial associations • Rhizoremediation of TPH-contaminated sites is a risk-based phytomanagement strategy

“…The stem leachate of Sonchus arvensis L. in the ratio of 1:20 (w/v) inhibits maize's seedling emergence and growth (Bashir et al, 2018). Besides, the saltgrass seed soaked with plant growth-promoting bacterial consortium for 2 hours had no signi cant effect on the germination performance (Xia et al, 2020). The slightly acidic electrolyzed water decontaminates the Enterobacteriaceae in alfalfa seeds growth (Zhang et al, 2021).…”

Basella rubra L. is a type of spinach, which is edible with high nutrient composition. It is also known to be an antioxidant. However, initial germination and root growth remain an issue due to hard exterior seed coating. Thus, some may germinate within 10 to 21 days, and some may not work at all. Inhibited growth may lead to vegetative propagation and micropropagation, which fundamentally reduce the growth and yield. Basella seed treated with Bokashi leachate was found to improve seed germination and root growth. A study was conducted using food waste EM Bokashi leachate (0:1, 1:1500, 1:1000, 1:500) with biopriming duration (6 and 12 hours). The experiment was conducted in a completely random design (CRD) with 3 replications of 100 seeds, with 24 experimental units. Based on the results, a short biopriming duration (6 hours) significantly enhanced the mean germination rate, germination speed accumulated, and coefficient of germination velocity. However, germination percentage had no significant improvement by leachate. Long priming duration significantly reduced the root development due to the seed may loss of desiccation tolerance. The concentration of leachate and priming duration had no significant interaction. In order to improve the germination and root growth performance, 6 hours of seeds priming duration or 1:500 (0.2%) of food waste Bokashi leachate was recommended to soak the Basella rubra seeds.
