From seed to storage: disease management in organic beetroot production to reduce food waste
Get PDFThe market for organic agriculture is rapidly growing. In Switzerland, the production of organic Beetroot is particularly renowned. However, their storage until spring has become increasingly difficult in recent years, and losses due to post-harvest rots can lead to over 50 % by March. Consequently, most organic beetroots sold in spring need to be imported if the previous season was poor. The causes of the various storage rots in beetroot are currently unclear, and therefore there are few measures to prevent them in organic production. Pathogen infections causing storage rots in beetroot, but also in other long-stored vegetables, can occur via the seed, in the field, or post-harvest. Understanding the process of infection is, therefore, critical to find preventive solutions. Here, we present the results of a three-year project aiming at reducing post-harvest losses in organic beetroot production. In a combination of on-farm field experiments and laboratory analyses, we aimed to elucidate the causes of storage rots in organic beetroot and develop measures to improve storability. Analysis of stored beetroot in 2021, 2022 and 2023 revealed Phoma betae, Fusarium sp. and Plectosphaerella sp. as predominant pathogens in Switzerland. Plectosphaerella sp. was never identified before on beetroot. Mortierella, Mucor and Alternaria were found to be additional causative agents of storage rots. Seeds analysis highlighted the same pathogen identified on the rotting tuber (Alternaria sp., Phoma betae and Fusarium sp.), suggesting that the possible cause may come directly from the seeds. Different measures, such as steam sterilization of the seed, the use of biocontrol products in the field and before storage, or processing and cooling methods after harvest, as well as cultivar differences were investigated. Various measures were found to affect seed health, seedling emergence, leaf health, and the quality of beetroot after storage

Holobiont-based genetic analysis reveals new plant and microbial markers for resistance against a root rot pathogen complex in pea
Get PDFBackground
The pea root rot complex is caused by various soil-borne pathogens that likely reinforce each other, influencing the composition of the root microbiome and leading to significant yield reductions. Previous studies have shown variations in the abundance of key microbial taxa and differences in disease susceptibility among plant genotypes. To better understand this relationship between plant genetics and microbiome dynamics, we conducted genetic analyses focusing on plant health and frequency of microbial taxa.
Results
Two hundred fifty-two diverse pea lines were grown in naturally infested soil under controlled conditions, genotyped, assessed for their disease symptoms at the seedling stage, and analyzed the associated root microbial communities using amplicon sequencing. Genome-wide association studies (GWAS) revealed genomic loci that influence the abundance of various fungal and bacterial operational taxonomic units (OTUs). We identified 54 independent quantitative trait loci (QTLs) significantly linked to the abundance of 98 out of 1227 detected OTUs, while an additional 20 QTLs were associated with more than one OTU. The most significant region was found on chromosome 6, influencing 50 OTUs across 10 distinct QTLs.
When comparing genomic markers and microbial OTUs as predictors in a genomic prediction model for root rot resistance and seedling emergence, we found that the abundance of specific microbial groups provided a significantly better predictive ability than QTLs. The abundance of Fusarium species was correlated with increased infection levels, while others, such as those linked to Dactylonectria and Chaetomiaceae, positively correlated with resistance to root rot. These findings were validated by specific QTLs and high genetic heritability for OTU abundance.
Conclusion
The results highlight two key points: (1) the presence and abundance of certain microbial groups in the pea root are influenced by distinct QTLs and, thus, determined by the plant genotype, and (2) these microbial communities show heritable correlations with the plant resistance to root rot. By combining plant and microbiome genetic markers—using a “holobiont” approach—we can improve predictions of root rot resistance compared to predictions based on plant genetics alone. These findings set a foundation for practical applications in breeding programs aimed at enhancing disease resistance through microbiome-assisted approaches
