Transcriptomic analyses reveal the effects of herbicides on the mycelium of Morchella sextelata

Project description:Morchella sextelata, recognized for its medicinal properties and distinctive taste, is a highly valued edible mushroom. Despite its commercial importance, the mushroom's susceptibility to environmental factors and its reactions to herbicides commonly used in cultivation have not been extensively studied. This research aimed to explore how four prevalent herbicides—Trifluralin, Pendimethalin, S-metolachlor, and Acetochlor—affect the mycelial growth of Morchella sextelata. The study involved cultivating the mycelium in a Potato Dextrose Agar (PDA) medium with concentrations of herbicides at ten times the standard application rate, followed by measuring the degree of mycelial growth inhibition. Employing transcriptomic analysis, RNA sequencing was conducted on the mycelium exposed to the herbicides. The subsequent transcriptome profiling indicated that the application of these herbicides impacted various biological pathways within Morchella sextelata, with a notable influence on glycolysis/gluconeogenesis and the glyoxylate cycle, which are crucial for energy production and metabolic processes. While Trifluralin and Pendimethalin demonstrated a less pronounced negative impact on mycelial growth, the study concluded that all tested herbicides were detrimental to Morchella sextelata. It is thus recommended that, in agricultural practice, the use of herbicides be approached with caution, and that application rates be strictly adhered to in order to ensure the healthy cultivation of Morchella sextelata and minimize potential pesticide residue issues.

Transcriptome and metabolome analyses reveal the regulatory network governing red fruitbody disease in Morchella

Project description:True morels (Morchella spp., Morchellaceae, Ascomycota), a delicious edible mushroom, has rapidly expanded in recent years, especially in China. However, a severe disease of morels, red fruitbody disease, led to very low production of fruiting bodies. The cause reason and the mechanisms under red fruitbody are unclear. Herein, we integrated the transcriptomics and metabolomics data of M. sextelata from red fruitbody group (R) and normal group (N), which was artificial cultivation in Fujian province, China. Transcriptome data revealed the differentially expressed genes (DEGs) between R group and N group were significantly enriched in the pathways of tyrosine metabolism, riboflavin metabolism, and glycerophospholipid metabolism. Similarly, the differential accumulated metabolites (DAMs) were mainly assigned to metabolism categories, including tyrosine metabolism, biosynthesis of plant secondary metabolites, biosynthesis of amino acids, and others. Then, combined analysis of the transcriptome data and metabolome traits revealed that the most enriched pathway was tyrosine metabolism, followed by ABC transporters, alanine, aspartate and glutamate metabolism, and others. In summary, this integration of transcriptomics and metabolomics data of M. sextelata during fruitbody redness implicated several key genes, metabolites, and pathways involved in this disease. We believe that these findings will help us understand the mechanisms under fruitbody redness of M. sextelata and provide new clues for optimizing the methods for its cultivation application.

Proteomics Analyses of Mycelium and Cysts of Phytophthora capsici

Project description:In this project, we have performed a comparative analysis of the proteomes of the mycelium and cysts of P. capsici. The identified proteins were functionally classified, which provides the basis for future research on these developmental stages of P. capsici and closely related species. Many of the proteins enriched in either the mycelium or cysts were found to contribute specific functions in these two life stages. Proteins enriched in mycelium were essentially associated with vegetative growth, whereas those enriched in cysts were primarily related to development-specific processes associated with the initiation of infection. The data provide a better understanding of the metabolic pathways underlying the mycelial and cyst developmental stages of P. capsici and point to potential targets of anti-oomycete compounds at each of these stages.
