In the quest for sustainable agricultural practices, there arises an urgent need for alternative solutions to mineral fertilizers and pesticides, aiming to diminish the environmental footprint of farming. Arbuscular mycorrhizal fungi (AMF) emerge as a promising avenue, bestowing plants with heightened nutrient absorption capabilities while alleviating plant stress. Cereal and oilseed crops benefit from this association in a number of ways, including improved growth fitness, nutrient uptake, and tolerance to environmental stresses. Understanding the molecular mechanisms shaping the impact of AMF on these crops offers encouraging prospects for a more efficient use of these beneficial microorganisms to mitigate climate change-related stressors on plant functioning and productivity. An increased number of studies highlighted the boosting effect of AMF on grain and oil crops' tolerance to (a)biotic stresses while limited ones investigated the molecular aspects orchestrating the different involved mechanisms. This review gives an extensive overview of the different strategies initiated by mycorrhizal cereal and oilseed plants to manage the deleterious effects of environmental stress. We also discuss the molecular drivers and mechanistic concepts to unveil the molecular machinery triggered by AMF to alleviate the tolerance of these crops to stressors.

Cover crops can suppress the following crop diseases and alter soil microbial communities, but the mechanisms of such disease suppressive effects remain uncertain. Here, we studied the effects of brassica and cereal cover crops, along with decomposition solutions from these crop residues, on tomato growth and bacterial wilt. Moreover, tomato rhizosphere microorganisms were analyzed by qPCR and high-throughput sequencing.

Article Synopsis
- - Aspergillus species are known for producing polyketides that lead to aflatoxins, which are harmful mycotoxins found in grains, seeds, and nuts, affecting both the agricultural field and storage processes.
- - The key aflatoxin-producing species include A. flavus, A. parasiticus, and A. nomius, along with others, and their toxin production is influenced by specific genes, particularly the aflR gene, though its presence doesn't guarantee toxin production.
- - Evolutionary studies show that some non-aflatoxigenic species may have derived from aflatoxin-producing ancestors, and genetic analyses reveal differences in gene clusters responsible for aflatoxin production between species.

Proteins from plant sources including legumes, cereals and oilseeds are gaining attention due to their suitability for sustainable production, functionality, and positive consumer perception. On the other hand, polyphenols (PPs) are receiving considerable attention as natural ingredients in the human diet due to their potent antioxidant and anti-inflammatory properties. Recent studies indicate that the emulsifying properties of plant proteins (PLPs) can be improved after modification through covalent and/or non-covalent interactions with PPs due to the changes in the conformation and/or the surface chemistry of the proteins.

The context of the peer review was that required by Regulation (EC) No 1107/2009 of the European Parliament and of the Council. The conclusions were reached on the basis of the evaluation of the representative uses of bixlozone as an herbicide on winter cereals (wheat and barley), winter oilseed rape and maize via soil broadcast spray application in field.

studies of gas production (GP) using rumen fluid obtained from rumen-cannulated animals are common in feed evaluation for ruminants. The objective was to compare sheep faeces with rumen fluid from dairy cows as inocula in the Hohenheim gas test (HGT) using a large number of different-quality feeds. It then was evaluated whether GP obtained by using rumen inoculum (RI-GP) can be estimated from GP using faecal inoculum (FI-GP).
