“…Similar results were observed by Fan [20], that zinc finger protein genes were also activated in the plants under reactive oxygen species and lipid peroxidation stress which causes decreased cell growth and biogenesis, including microtubule-based processes and nucleosome assembly. There was variation of the zinc finger protein gene expression under hypoxia stress in rice plants [15]. The results revealed that gene expression was lowered in combined treatments of bacteria and ZnO NPs (Figures 7 and 8).…”

“…Zinc oxide nanoparticles are used as non-fertilizers that act as important adsorbents for remediation, due to the fact that they carry various functional hydroxyl groups and protons on their surfaces [13]. Furthermore, zinc defends plant cell organelles from oxidative stress and functions as a participant in the plant's defense system [14,15]. Bio-primed seeds (seeds with bacterial inoculum) growing in ZnO NPs solution are a simple, and easily adaptable strategy to mitigate stress and improve the germination of seeds.…”

Heavy metal (HM) emissions have increased due to the impact of rising urbanization and anthropogenic activity, affecting different parts of the environment. The goal of this study is to investigate the combined effect of ZnO NPs and bacteria treatment on protein and gene expression profiles of rice plants that are grown in HMs-polluted water. Seeds were primed with Bacillus spp. (Bacillus cereus and Lysinibacillus macroides) before being cultured in Hoagland media containing ZnO NPs (5 and 10 mg/L) and HMs-contaminated water from the Hayatabad industrial estate (HIE), Peshawar, Pakistan. The results revealed that the maximum nitrogen and protein content was observed in the root, shoot, and leaf of the plant grown by combining bacteria-ZnO NPs treatment under HMs stress as compared with plant grown without or with individual treatments of ZnO NPs and bacteria. Furthermore, protein expression analysis by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) revealed that plants that were grown in HMs-polluted water were found to be affected in contaminated water, however the combined effect of bacteria-ZnO NPs reported the more dense protein profile as compared with their individual treatments. Subsequently, plants that were grown in HMs-polluted water have the highest expression levels of stress-induced genes such as myeloblastosis (Myb), zinc-finger protein (Zat-12), and ascorbate peroxidase (Apx) while the combined effect revealed minimum expression as compared with individual treatments. It is concluded that the combined effect of ZnO NPs and bacteria lowered the stress-induced gene expression while it increased the nitrogen-protein content and protein expression in plant grown under HMs stress.

“…have been employed in seed primings on crops (summarized in Table 1 and Figure 1). Seed priming of chilli with PGPFs T. harzianum, T. asperellum, and PGFR Paenibacillus dendritiformis triggers physiological, transcriptional, and metabolic changes such as ROS burst and induction of defense-related enzymes and phenolic compounds, as well as increased disease resistance against anthracnose disease (Mitra et al, 2021;Yadav et al, 2021). Sugar beet primed with the PGPF T. atroviride exhibited upregulation of defense gene BvPR3 and induced systemic resistance against Cercospora leaf spot (CLS) disease (Kappel et al, 2022).…”

Priming seeds for the future: Plant immune memory and application in crop protection

2022

Plants have evolved adaptive strategies to cope with pathogen infections that seriously threaten plant viability and crop productivity. Upon the perception of invading pathogens, the plant immune system is primed, establishing an immune memory that allows primed plants to respond more efficiently to the upcoming pathogen attacks. Physiological, transcriptional, metabolic, and epigenetic changes are induced during defense priming, which is essential to the establishment and maintenance of plant immune memory. As an environmental-friendly technique in crop protection, seed priming could effectively induce plant immune memory. In this review, we highlighted the recent advances in the establishment and maintenance mechanisms of plant defense priming and the immune memory associated, and discussed strategies and challenges in exploiting seed priming on crops to enhance disease resistance.

“…Cardarelli et al [ 8 ] reported that the application of beneficial microorganisms to the seeds of the major crops resulted in increased germination, seedling vigor, biomass, and the ability to overcome stress both during and after emergence. Generally, seed bio-priming with PGPR improves seed quality, plant growth and stress tolerance through production of regulatory substances, nutrient enhancement, and plant protection [ 38 ]. It initiates physiological processes linked to increased activity of hydrolytic and detoxifying enzymes, ROS, modifications of hormone levels, and gene expression in plants [ 39 ].…”

Bio-priming is a new technique of seed treatment that improves seed germination, vigor, crop growth and yield. The objective of this study was to evaluate the effectiveness of Bradyrhizobium japonicum (commercial strains) and Bacillus megaterium (newly isolated strains) as a single inoculant and co-inoculant during seed bio-priming to improve seed germination and initial seedling growth of two soybean cultivars. The treated seeds were subjected to germination test (GT), cold test (CT) and accelerated aging test (AAT). B. megaterium significantly improved all parameters in GT and CT; final germination, shoot length, root length, root dry weight, and seedling vigor index in AAT, as compared to control. In addition, co-inoculation significantly increased all parameters except shoot dry weight in GT; all parameters in CT; germination energy, shoot length, root length, and seedling vigor index in AAT, in comparison to the control. Moreover, Br. japonicum significantly improved the germination energy, shoot length, shoot dry weight, root dry weight, and seedling vigor index in GT; all parameters in CT; shoot length, root length, and seedling vigor index in AAT, compared with non-primed seeds. Thus, B. megaterium strains could be used in soybean bio-priming as a potential single inoculant and co-inoculant, following proper field evaluation.
