Special Issue Information

Dear Colleagues,

Disease suppressive soil has been defined as the soil in which disease incidence or severity still persists at a low level, even in the presence of the pathogen, susceptible host crop, and climatic conditions conducive to disease occurrence. With the understanding of the necessity to reduce the application of chemical pesticides, suppressive soil has emerged as a research hotspot with important implications for developing more sustainable agriculture. Disease-suppressive soil could provide a basis for manipulating soil communities to generate sustainable alternate strategies for pathogen control, and soils suppressive to soil-borne pathogens have been discovered for a range of crops across many locations. However, it still remains largely unknown with respect to the role of the soil microbiome in supporting plant health.

This Special Issue aims at deciphering the key characteristics of the soil microbiome in disease suppression across different crop types. Furthermore, the exploration of ecological functions of key microbes regarding disease suppression is encouraged. Together, the final purpose of this Special Issue is to manage soil-borne disease by manipulating the soil microbiome by following green and sustainable methods.

Multi-omics studies, synthesized microbial consortia, soil legacy, and feedbacks between the soil microbiome and plant health are cutting-edge research methods for investigating the roles of soil microbiomes in determining soil suppressiveness against soil-borne disease.

This Special Issue hosts original research articles and reviews on the role of the soil microbiome in disease-suppressive soils and its potential in soil-borne diseases. Methodological contributions, case studies, and advances in modeling on both fundamental and applied studies are warmly welcomed, with emphasis on the composition and functionality of the soil microbiome in disease suppressive and critical microbes contributing to disease suppression in controlling soil-borne disease.

The large outbreak of banana Fusarium wilt has become a bottleneck limiting the industry’s development, and crop rotation is a cost-effective and essential measure to overcome the obstacles of banana crop monoculture. The present work was carried out to explore the mechanisms of how changes in soil chemical properties and the reestablishment of soil microorganisms in high-incidence soils are affected by crop rotation and plant residue. In this study, pineapple–banana crop rotation and pineapple residue amendment were carried out to alleviate banana Fusarium wilt, and their effects on bacterial and fungal communities were analyzed using the MiSeq Illumina sequencing platform. Both pineapple–banana rotation and residue addition significantly reduced disease incidence. Moreover, pineapple rotation and residue amendment altered the bacterial and fungal community composition. The taxonomic and phylogenetic alpha diversity of bacteria and fungi significantly increased against disease suppression and nutrition competition. The relative abundances of the Burkholderia, Pseudomonas, Elaphocordyceps, Penicillium, and Talaromyces genera were higher, and the number of Fusarium was significantly lower in rotational soil than in banana monoculture soil. Finally, linear models (LM) showed that the Burkholderia and Talaromyces in crop rotation, and Aspergillus in residue amendment had a significantly negative relationship to disease incidence, which plays a key role in Fusarium reduction. To consider the economic benefits and protect the vitality of the soil, this study suggested that pineapple–banana rotation and pineapple residue amendment both could be considered for the sustainable management of banana wilt.
