Special Issue Information

Dear Colleagues,

In natural environments, plants rely on microorganisms to deal with biotic and abiotic stresses, outsourcing to the microbial partner important functions like water and nutrient acquisition and defense against pathogens and pests. However, most plant breeding programs have ignored these beneficial interactions, shaping crops to rely on intensive applications of chemical fertilizers and defensives instead. Therefore, plant domestication has provoked significant changes in the plant microbiome and has caused the loss of plants’ ability to establish some beneficial interactions. The reinstatement of these beneficial interactions is essential for making crops more efficient and less dependent on agrochemicals. Many attempts at progress related to microorganisms have been made, with a long history of research on inoculants and biological control agents, and many of them have reached the market as biological formulations. However, we still exploit a small fraction of the available microbial diversity. At the same time, plant strategies are scarce, and this may be impairing the success of microbial applications due to plants’ inability to establish a relationship with applied microorganisms.

In this Special Issue, we seek to highlight integrative studies showing novel plant- or microorganism-based strategies to reinstate beneficial plant–microorganism interactions for resilient farming. We will also consider reviews that clearly systematize existing knowledge and point out research gaps and new perspectives.

Anthracocystis panici-leucophaei, causal agent of smut on Digitaria insularis (sourgrass), was evaluated as a biological control agent for this weed. Two types of inocula (teliospore and sporidia) were tested to assess its infectivity. The effects of teliospore and sporidia inoculations at different phenological stages of sourgrass were compared, as well as the potential of sporidia and teliospores in post-emergence sourgrass management. Virulence tests were conducted with the isolates obtained from D. insularis and evaluation of specificity of A. panici-leucophaei. Both teliospores and sporidia of A. panici-leucophaei are infective to D. insularis in three different phenological stages. Newly emerged plants with one pair of leaves are more sensitive to A. panici-leucophaei. Infection by A. panici-leucophaei inhibits the growth of sourgrass, decreasing several physiological parameters of D. insularis plants. The fungus produces systematic infection of sourgrass plants and may induce the formation of sori in a significant proportion of the plant panicles, partly castrating those plants. Among sixteen A. panici-peucophaei isolates tested, isolate 46 was the most virulent and inhibited the growth of sourgrass plants, and thus appears to have good potential as a biological control agent to be deployed against sourgrass. A. panici-leucophaei was demonstrated to be specific to D. insularis. Full article

In a long-term monoculture with fruit trees and tree nurseries, it is necessary to regenerate the soil due to the risk of apple replant disease (ARD). The occurrence of ARD is manifested in the structure of the mycobiome. The assumption of our experiment was that the use of oil radish (Raphanus sativus var. oleifera), white mustard (Sinapis alba), and marigold (Tagetes patula L.) as phytosanitary plants for biofumigation would provide crops with nutrients, improve soil physicochemical properties, and influence the diversity of microbiota, including fungal networks, towards a beneficial mycobiome. Metagenomic analysis of fungal populations based on the hypervariable ITS1 region was used for assessing changes in the soil mycobiome. It showed that biofumigation, mainly with a forecrop of marigold (Tagetes patula L.) (R3), caused an improvement in soil physicochemical properties (bulk density and humus) and the highest increase in the abundance of operational taxonomic units (OTUs) of the Fungi kingdom, which was similar to that of agriculturally undegraded soils, and amounted to 54.37%. In this variant of the experiment, the most OTUs were identified at the phylum level, for Ascomycota (39.82%) and Mortierellomycota beneficial fungi (7.73%). There were no such dependencies in the soils replanted with forecrops of oilseed radish (Raphanus sativus var. oleifera) and white mustard (Sinapis alba). Biofumigation with marigold and oil radish contributed to a reduction in the genus Fusarium, which contains several significant plant-pathogenic species. The percentages of operational taxonomic units (OTUs) of Fusarium spp. decreased from 1.57% to 0.17% and 0.47%, respectively. Full article
