Summary: Mycorrhizal associations play a crucial role in orchid germination and seedling establishment, potentially impacting the distribution and abundance of orchids in natural conditions. The mycoheterotrophic orchid Gastrodia confusoides displays random aboveground spatial patterns of distribution within bamboo forests, possibly due to the scattered distribution of litter-decaying fungi. Our study provides evidence that the abundance of litter-decaying fungi varies randomly within the bamboo forest and independently from G. confusoides adults.

Summary: This study elucidated the upregulation of lignin-modifying enzyme genes in Mycena, increased biological activity in G. elata seeds during symbiosis, and the reduction of ABA biosynthesis and signaling in G. elata. The findings suggest that Mycena hyphae enhance lignin degradation to facilitate germination, while G. elata reduces ABA levels to promote seed dormancy release.

Summary: A new Mycena subpiligera species was discovered in subtropical areas of China, which can greatly enhance the germination efficiency of Gastrodia elata seeds. Through morphological comparison and genetic analysis, this new taxon was distinguished from similar phenotypes and phylogenetically related species. Optimal cultural conditions were reported, and the germination rate was compared with another Mycena species.

Summary: Similar to other orchid species, Paphiopedilum hirsutissimum relies on mycorrhizal fungi for seed germination and seedling development. This study identified a specific strain of endophytic fungus that supports the advanced developmental stage of P. hirsutissimum seedlings. The findings have ecological value and may contribute to the protection and reintroduction of endangered orchid species.

Summary: This paper proposes an I-YOLOX object detection algorithm based on deep learning and computer vision to improve the efficiency and accuracy of identifying the grade of Gastrodia elata in the market. The improved model outperforms other target detection algorithms in terms of mean average precision, model size, computation amount, and frames per second, providing a theoretical basis for the development of online identification systems of different grades of Gastrodia elata in practical production.

Summary: The study found that arbuscular mycorrhizal fungi (AMF) can enhance maize defense response by increasing the expression of mpi and pr5, rather than solely increasing plant nitrogen and phosphorous content. Fertilization treatments did not alter the upregulation of induced defense genes, suggesting that the mechanism through which AMF upregulate defenses is not solely via increased plant nutrition.

Summary: This study investigated the growth and propagation of Gastrodia elata using tissue culture. It found that adding specific nutrients can accelerate seed germination and the growth of juvenile rhizomes. The in vitro propagation system can be an effective method for the cultivation of Gastrodia elata.

Summary: This study investigates the combined effects of arbuscular mycorrhizal fungi (AMF) and above- and belowground herbivory on plant productivity and subsequent herbivore performance. The results show that both AMF and tuber herbivory increase tuber biomass and primary metabolites. Tuber herbivory enhances the performance of subsequent conspecifics feeding on tubers, but only in plants inoculated with AMF.

Summary: This study reveals that the effects of arbuscular mycorrhizal fungi (AMF) on plant growth vary due to plant-AMF specificity. The native AMF from Poa annua shows broad-spectrum benefits on various plants, indicating its potential utilization in the restoration of desert vegetation.

Summary: Mycorrhiza is a symbiotic association between plant roots and fungi, with arbuscular mycorrhizal fungi (AMF) being the most prominent type. AMF rely on host plants for photosynthates and provide benefits in return. They help improve host plants' tolerance against various biotic stresses through mechanisms like nutrient competition and rhizosphere alteration. The effectiveness of AM associations in conferring biotic stress tolerance is influenced by various biotic and abiotic factors.

Summary: The plant symbiotic fungus Metarhizium robertsii can degrade and reduce methylmercury and divalent mercury, thereby decreasing mercury accumulation in plants and improving their growth in contaminated soils. This fungus achieves this through the action of methylmercury demethylase and mercury ion reductase. The mechanisms underlying mercury tolerance in fungi involve horizontal gene transfer from bacteria. Heterologous expression of methylmercury demethylase enables fungi lacking this gene to also demethylate methylmercury.

Summary: Compatible fungi can promote the germination and seedling formation of Dendrobium officinale seeds, while incompatible fungi cannot continuously colonize seeds and support seedling development. Seed pretreatment can improve seed germination, but cannot change the compatibility of a fungus with an orchid. Without a seed coat, the incompatible fungus is still unable to colonize in vitro-produced protocorms or support seedling development.
