AI Article Synopsis
- The study investigates the effects of ectomycorrhizal fungi on the growth of hazelnut roots and the associated gene expression changes.
- Results showed that hazelnut plants inoculated with the fungus exhibited significantly better growth, with increased weights and root characteristics compared to control plants.
- Analyses revealed notable gene expression changes, particularly in genes related to auxin transport and signaling, suggesting that these may play a role in promoting root development when mycorrhiza is formed.
Article Abstract
Introduction: can form symbiotic ectomycorrhizal fungi with hazel roots. The mechanism through which promotes hazelnut growth remains unclear.
Methods: This study aimed to evaluate the effect of ectomycorrhizal fungus on the growth and development of hazel roots and gene expression changes through comparative transcriptome analysis.
Results: After inoculation with , the fungus symbiotically formed ectomycorrhiza with hazel roots. The fresh weights of the aboveground and underground parts of My treatment (inoculated with S. bovista and formed mycorrhiza) were much higher than those of the control, respectively. The length, project area, surface area, volume, forks, and diameter of the inoculated seedlings root were 1.13 to 2.48 times higher than those of the control. In the paired comparison, 3,265 upregulated and 1,916 downregulated genes were identified. The most significantly enriched Gene Ontology term for the upregulated Differentially Expressed Genes was GO:0005215 (transporter activity). Immunohistochemical analysis suggested that the expression levels of auxin and Auxin Response Factor9 were significantly increased by after the formation of mycorrhizal fungi in hazelnut root tips.
Discussion: These results indicate that genes related to auxin biosynthesis, transport and signaling, and transport of nutrients may contribute to root development regulation in hazel ectomycorrhiza.

Physiological and molecular mechanisms underpinning plant water stress responses still need deeper investigation. Particularly, the analysis of rootstock-mediated signals represents a complex research field, offering potential applicative perspectives for improving the adaptation of fruit crops to environmental stresses. Nonetheless, fundamental knowledge on this subject needs to be widened, especially in some woody species, including European hazelnut (Corylus avellana L).

Introduction: Over the course of four consecutive years, a comparative study, for the first time, was carried out to assess their growth characteristics, vegetative and productive performances.
Material: Micropropagated, grafted on not suckering rootstock and own-rooted plants by layering from three Italian hazelnut ( L.) cultivars were established in the same orchard and environmental condition.

Tuber borchii forms ectomycorrhiza with oaks, hazel, and pines, including Pinus sylvestris. However, its ectomycorrhiza morphotype with P. sylvestris was not comprehensively described so far, and molecular analyses are missing despite a high danger of misidentification of T.
