Special Issue Information

Dear Colleagues,

Plant–fungi interactions, a pivotal research area within ecology and environmental science, hold profound scientific significance and real-world importance. Over several decades, scientists have been delving into this domain, revealing the intricate relationships between plants and fungi, which profoundly influence ecosystems’ structure and functioning. From mutualistic associations, such as mycorrhizal symbiosis, to the decomposition of organic matter contributing to nutrient cycling, this field provides profound insights into how ecosystems operate. The importance of this research lies in unlocking the mysteries of the natural world and its practical applications for the health of ecosystems, the preservation of biodiversity, sustainable agriculture, climate change mitigation, and ecological restoration. In this Special Issue, we will delve deeper into this critical research area, aiming to offer fresh insights and perspectives on the significance and applied potential of plant-fungi interactions.

For this Special Issue, we encourage the submission of manuscripts on any aspects of plant–fungi interaction that provide valuable insight to the scientific community. We aim to bring together cutting-edge research, insights, and innovative approaches that shed light on the intricate relationships between plants and fungi and their far-reaching consequences for nutrient cycling and ecosystem functioning. We hope this collection of articles will contribute to the scientific knowledge base and offer practical applications and solutions for addressing ecological challenges in our rapidly changing world.

Paraphoma chrysanthemicola, an endophytic fungus isolated from the roots of Codonopsis pilosula, influences salicylic acid (SA) levels. The interaction mechanism between SA and P. chrysanthemicola within C. pilosula remains elusive. To elucidate this, an experiment was conducted with four treatments: sterile water (CK), P. chrysanthemicola (FG), SA, and a combination of P. chrysanthemicola with salicylic acid (FG+SA). Results indicated that P. chrysanthemicola enhanced plant growth and counteracted the growth inhibition caused by exogenous SA. Physiological analysis showed that P. chrysanthemicola reduced carbohydrate content and enzymatic activity in C. pilosula without affecting total chlorophyll concentration and attenuated the increase in these parameters induced by exogenous SA. Secondary metabolite profiling showed a decrease in soluble proteins and lobetyolin levels in the FG group, whereas SA treatment led to an increase. Both P. chrysanthemicola and SA treatments decreased antioxidase-like activity. Notably, the FG group exhibited higher nitric oxide (NO) levels, and the SA group exhibited higher hydrogen peroxide (H2O2) levels in the stems. This study elucidated the intricate context of the symbiotic dynamics between the plant species P. chrysanthemicola and C. pilosula, where an antagonistic interaction involving salicylic acid was prominently observed. This antagonism was observed in the equilibrium between carbohydrate metabolism and secondary metabolism. This equilibrium had the potential to engage reactive oxygen species (ROS) and nitric oxide (NO). Full article
