Wheat is an important cereal crop species consumed globally. The growing global population demands a rapid and sustainable growth of agricultural systems. The development of genetically efficient wheat varieties has solved the global demand for wheat to a greater extent. The use of chemical substances for pathogen control and chemical fertilizers for enhanced agronomic traits also proved advantageous but at the cost of environmental health. An efficient alternative environment-friendly strategy would be the use of beneficial microorganisms growing on plants, which have the potential of controlling plant pathogens as well as enhancing the host plant’s water and mineral availability and absorption along with conferring tolerance to different stresses. Therefore, a thorough understanding of plant-microbe interaction, identification of beneficial microbes and their roles, and finally harnessing their beneficial functions to enhance sustainable agriculture without altering the environmental quality is appealing. The wheat microbiome shows prominent variations with the developmental stage, tissue type, environmental conditions, genotype, and age of the plant. A diverse array of bacterial and fungal classes, genera, and species was found to be associated with stems, leaves, roots, seeds, spikes, and rhizospheres, etc., which play a beneficial role in wheat. Harnessing the beneficial aspect of these microbes is a promising method for enhancing the performance of wheat under different environmental stresses. This review focuses on the microbiomes associated with wheat, their spatio-temporal dynamics, and their involvement in mitigating biotic and abiotic stresses.

Global warming influences environmental factors which directly and indirectly affects agricultural crop production by exposing to several new biotic and abiotic stresses. The abiotic stresses like heat, drought, moisture, salinity and pre harvest sprouting stresses are most common whose effect became more severe due to climate change. Globally wheat is the most widely cultivated and used crops due to its economic and social values. Its production and productivity are highly vulnerable to these abiotic stresses. The development of wheat varieties tolerant to these abiotic stresses is a very challenging assignment for wheat researchers. The conventional breeding program is being practiced for such objectives but it will not be sufficient to achieve the target production and more advanced research is needed for better understanding the mechanism of these stresses and how plants became more tolerant. The progress made in the understanding of these abiotic stress tolerances is due to advances in three main research areas: physiology, genetic, and breeding research. Identifying morphological traits, physiological and biochemical traits for précised phenotyping and associated genes contributing to particular stress tolerance is very important under mitigation strategy. Previous studies showed that some abiotic stress tolerance is controlled by a polygene and its genetic constitution will help to analyze the gene network(s) controlling stress tolerance. Furthermore, stress mitigation options particularly through the application of plant hormones, several agronomic interventions, genetic and biotechnological management strategy are convenient for improving plant performances under various abiotic stresses are also essential to stabilize the wheat productivity.

“…Novel approaches for sustainable and economical crop production under ever-changing climate conditions include microbiome-facilitated crop management strategies ( Liu et al., 2020 ; Trivedi et al., 2021 ). Beneficial plant-associated microbes include predominantly rhizobacteria and fungi as well as viruses, actinomycetes, cyanobacteria, archaea ( Mauch-Mani et al., 2017 ; Mahapatra et al., 2020 ). The barley-microbiome was reported to largely vary between the different plant organs, developmental stages, origin, as well as between genotypes ( Yang et al., 2017 ; Alegria Terrazas et al., 2020 ; Bziuk et al., 2021 ).…”

Leaf rust caused by Puccinia hordei is one of the major diseases of barley (Hordeum vulgare L.) leading to yield losses up to 60%. Even though, resistance genes Rph1 to Rph28 are known, most of these are already overcome. In this context, priming may promote enhanced resistance to P. hordei. Several bacterial communities such as the soil bacterium Ensifer (syn. Sinorhizobium) meliloti are reported to induce resistance by priming. During quorum sensing in populations of gram negative bacteria, they produce N-acyl homoserine-lactones (AHL), which induce resistance in plants in a species- and genotype-specific manner. Therefore, the present study aims to detect genotypic differences in the response of barley to AHL, followed by the identification of genomic regions involved in priming efficiency of barley. A diverse set of 198 spring barley accessions was treated with a repaired E. meliloti natural mutant strain expR+ch producing a substantial amount of AHL and a transformed E. meliloti strain carrying the lactonase gene attM from Agrobacterium tumefaciens. For P. hordei resistance the diseased leaf area and the infection type were scored 12 dpi (days post-inoculation), and the corresponding relative infection and priming efficiency were calculated. Results revealed significant effects (p<0.001) of the bacterial treatment indicating a positive effect of priming on resistance to P. hordei. In a genome‐wide association study (GWAS), based on the observed phenotypic differences and 493,846 filtered SNPs derived from the Illumina 9k iSelect chip, genotyping by sequencing (GBS), and exome capture data, 11 quantitative trait loci (QTL) were identified with a hot spot on the short arm of the barley chromosome 6H, associated to improved resistance to P. hordei after priming with E. meliloti expR+ch. Genes in these QTL regions represent promising candidates for future research on the mechanisms of plant-microbe interactions.
