“…An interesting avenue is to harness variations in exudation patterns to enhance the beneficial rhizosphere microbiome (Quiza et al, 2015). The microbiome can be engineered by traditionally amending soil with (in)organic supplementation and agricultural practices to promote microbial diversity, functions and interactions with the targeted host (Figure 2; Sankar Ganesh et al, 2017;Saeid and Chojnacka, 2019). Therefore, the living components of the rhizosphere can be engineered to promote plant health and growth, two features that strongly depend upon the interactions of living organisms with their environment (Dessaux et al, 2016).…”

Plant microbiome (or phytomicrobiome) engineering (PME) is an anticipated untapped alternative strategy that could be exploited for plant growth, health and productivity under different environmental conditions. It has been proven that the phytomicrobiome has crucial contributions to plant health, pathogen control and tolerance under drastic environmental (a)biotic constraints. Consistent with plant health and safety, in this article we address the fundamental role of plant microbiome and its insights in plant health and productivity. We also explore the potential of plant microbiome under environmental restrictions and the proposition of improving microbial functions that can be supportive for better plant growth and production. Understanding the crucial role of plant associated microbial communities, we propose how the associated microbial actions could be enhanced to improve plant growth-promoting mechanisms, with a particular emphasis on plant beneficial fungi. Additionally, we suggest the possible plant strategies to adapt to a harsh environment by manipulating plant microbiomes. However, our current understanding of the microbiome is still in its infancy, and the major perturbations, such as anthropocentric actions, are not fully understood. Therefore, this work highlights the importance of manipulating the beneficial plant microbiome to create more sustainable agriculture, particularly under different environmental stressors.

“…Arif et al (2020) consider the prospect of selecting the holonbiont component for varietal selection as promising to improve yields and resilience of agroecosystems. Indeed, beneficial microorganisms provide important ecosystem services (Sankar Ganesh et al, 2017;Syed Ab Rahman et al, 2018;Saied and Chojnacka, 2019). Sahu and Mishra (2021) refer to the holonbiont selection as an emerging discipline integrating the genome and the microbiome.…”

Given the limits of intensive agriculture (pollution, degradation of biodiversity, or soil desertification), it is necessary to develop sustainable alternatives to respond to future agricultural demand. Among these sustainable alternatives is the use of microbial biostimulants. Despite convincing scientific studies on them, their agricultural use remains minor. This can be explained by the lack of efficiency and reliability of their use. This review proposes to develop efficient microbial biostimulants based on the combination of two approaches, namely that of endophytic bacteria from seeds and the Back to the Future approach. Seed endophytic bacteria have a major agroindustrial potential insofar as they stand out from other microbial agents by their resistance, competitiveness, efficiency, and vertical transmission. Contrary to modern cultivars, non-domesticated plants harbor microbiomes which have not been impacted by the processes of domestication and agriculture intensification. The Back to the Future suggests therefore to use interesting microorganisms isolated from non-domesticated plants and to integrate them into modern cultivars. This could result in the rehabilitation of modern microbiomes and lead to make crop cultures more resistant and resilient. The idea consisting in the combination of both approaches aims at obtaining optimized microbiomes. Particular emphasis is placed on integrating these innovative microbiomes into variety breeding programs. Indeed, given the importance of plant-microorganism interactions, particularly from an agronomic point of view, taking the hologenome into account as a unit of selection in breeding programs is essential. This integrative and unprecedented approach to designing breeding programs is promising with a view to reconciling productivity and preservation of agroecosystems.

“…Of all nutrients, N is needed in the largest quantities since N is crucial for plant growth [6]. In organic fertilizers, the content of total-N and of mineral-N (NH ) are key factors determining the N availability, especially in the short term [2].…”

“…It is worth mentioning that in the case of feedstock with high N levels like animal slurry or manure, inhibition of the anaerobic digestion can occur, especially in thermophilic reactors due to overly free ammonia [4]. Besides, P and K are also essential macronutrients for the plants growth and function and these are required in relatively large quantities by plants [6]. P and K are usually preserved during the anaerobic digestion process [7] and actually, they might be concentrated in the digestate together with recalcitrant compounds [8].…”
