“…The role of biostimulants, specifically in regard to growth promotion and nutrient availability, has been reviewed (du Jardin [1,[4][5][6]). In addition to numerous general reviews, many categories of specific biostimulants have been extensively reviewed such as protein hydrolysates [7], seaweed extracts [8], silicon [9], chitosan [10], humic and fulvic acids [11], the role of phosphite [12], arbuscular mycorrhizal fungi [13], trichoderma [14], plant growth-promoting rhizobacteria [15]. These reviews have focused on plant growth promotion and biotic stress but our intent with this review is to comprehensively address what is known about biostimulants ameliorating the effects of abiotic stress ( Table 1).…”

The use of bioeffectors, formally known as plant biostimulants, has become common practice in agriculture and provides a number of benefits in stimulating growth and protecting against stress. A biostimulant is loosely defined as an organic material and/or microorganism that is applied to enhance nutrient uptake, stimulate growth, enhance stress tolerance or crop quality. This review is intended to provide a broad overview of known effects of biostimulants and their ability to improve tolerance to abiotic stresses. Inoculation or application of extracts from algae or other plants have beneficial effects on growth and stress adaptation. Algal extracts, protein hydrolysates, humic and fulvic acids, and other compounded mixtures have properties beyond basic nutrition, often enhancing growth and stress tolerance. Non-pathogenic bacteria capable of colonizing roots and the rhizosphere also have a number of positive effects. These effects include higher yield, enhanced nutrient uptake and utilization, increased photosynthetic activity, and resistance to both biotic and abiotic stresses. While most biostimulants have numerous and diverse effects on plant growth, this review focuses on the bioprotective effects against abiotic stress. Agricultural biostimulants may contribute to make agriculture more sustainable and resilient and offer an alternative to synthetic protectants which have increasingly falling out of favour with consumers. An extensive review of the literature shows a clear role for a diverse number of biostimulants that have protective effects against abiotic stress but also reveals the urgent need to address the underlying mechanisms responsible for these effects.

“…There has been increasing interest and awareness across society of the benefits of mycorrhizal colonization of plants, be that in natural ecosystems (Read, 1991;van der Heijden & Horton, 2009), horticulture (Azcón-Aguilar & Barea, 1997;Rouphael et al, 2015), or in the agricultural industry (Gianinazzi & Vosátka, 2004;Thirkell et al, 2017). This growing awareness has resulted in an increase in the manufacture and marketing of mycorrhizal fungal inoculum to commercial and home growers (Vosátka, Látr, Gianinazzi, & Albrechtová, 2012) and rising urgency to develop a deeper understanding about how the way in which land is managed by farmers, foresters, or recreational gardeners may affect the functioning of the wider mycorrhizal network.…”

Societal Impact Statement Mycorrhizal fungi are of huge significance for plants, people, and the planet. In addition to the fruiting bodies of many mycorrhizal fungi having great culinary, medical, and sometimes religious significance, by forming partnerships with the vast majority of land plants, mycorrhizal fungi are essential in the formation and functioning of global ecosystems. As such, mycorrhizas have great potential for future exploitation and management to facilitate a variety of sustainability programs in agriculture, conservation, and restoration, considerations that are particularly relevant during this time of global change and widespread depletion of natural resources. Summary Mycorrhizal fungi, of all types, hold huge significance for our planet and society. By forming mutualistic symbioses with the vast majority of land plants, mycorrhizas play an essential role in the formation and maintenance of global ecosystems. They also have great potential for exploitation to facilitate a variety of sustainability programs in agriculture, conservation, and restoration, particularly relevant in the context of global climate change and depletion of natural resources. As such, in addition to the fruiting bodies of many mycorrhiza‐forming fungal species being delicious, mycorrhizal symbioses are of critical and increasingly appreciated importance to human society. This editorial provides an overview of the relevance and potential roles of mycorrhizal fungi toward achieving global goals in sustainability, conservation and their significance within society, and highlights key directions for future research.

“…Different strategies may be applied for enhancing the nutritional quality of food crops by using beneficial rhizospheric microorganisms: the manipulation of the crop microbiome in situ (Singh and Trivedi, 2017) and the external application of commercial inocula containing beneficial microorganisms in soils (Vos atka et al, 2012;Rouphael et al, 2015). The first approach requires the integration of emerging technologies (omics, for example) with traditional approaches of microbial ecology and plant ecophysiology.…”

“…While the extraradical hyphae that extend from the root into the soil increase the uptake of water and minerals, the establishment of the intraradical fungal structures involves a continuous cellular and molecular dialogue between AMF and plants that includes the activation of the antioxidant, phenylpropanoid or carotenoid metabolic pathways. The recent review by Rouphael et al (2015) summarizes the effects of AMF on crop tolerance to abiotic stresses, such as drought, salinity, nutrient deficiency, heavy metals and adverse soil pH, and also the role of AMF as enhancers of the nutraceutical value of horticultural products. However, the production of compounds beneficial for human health in the edible parts of crops has been investigated only in a limited number of plant species.…”

SummaryModern agriculture and horticulture must combine two objectives that seem to be almost mutually exclusive: to satisfy the nutritional needs of an increasing human population and to minimize the negative impact on the environment. These two objectives are included in the Goal 2 of the 2030 Agenda for Sustainable Development of the United Nations: ‘End hunger, achieve food security and improved nutrition and promote sustainable agriculture'. Enhancing the nutritional levels of vegetables would improve nutrient intake without requiring an increase in consumption. In this context, the use of beneficial rhizospheric microorganisms for improving, not only growth and yield, but also the nutrient quality of crops represents a promising tool that may respond to the challenges for modern agriculture and horticulture and represents an alternative to the genetic engineering of crops. This paper summarizes the state of the art, the current difficulties associated to the use of rhizospheric microorganisms as enhancers of the nutritional quality of food crops as well as the future prospects.
