Special Issue Information

Dear Colleagues,

In the past decades, the plant-fungus interactions, including mycorrhizal, parasitic or endophytic lifestyles, have been extensively studied at various aspects and have greatly improved our understanding. Among them, the symbiotic association of mycorrhiza is commonly found in most of vascular plants, mainly including arbuscular mycorrhiza, ectomycorrhiza, ericoid mycorrhiza and orchid mycorrhiza. Mycorrhizal fungi benefit most plants by enhancing their nutrient access and stress tolerance, and therefore strongly affect plant population and community biology by regulating seedling establishment and species coexistence. In this Topic, the interactions between plants and fungi will be considered. This includes but no limits, functional omics, molecular communication, coevolution, ecological adaption and nutrient modes of plant-fungi interactions, and applications of fungi for sustainable environmental management and plant conservation.

This Special Issue on “Advance Research in Plant-Fungi Interactions” is open to all researchers studying this interaction at any level, from both the plant and the fungi side. Papers are welcome as original research articles, as well as review papers dealing with the advancement and current understanding of various aspects of plant-fungus interactions.

Rhizosphere Microbe Affects Soil Available Nitrogen and Its Implication for the Ecological Adaptability and Rapid Growth of Dendrocalamus sinicus, the Strongest Bamboo in the World

and

Abstract

The interaction between soil microbes and plants has a significant effect on soil microbial structure and function, as well as plant adaptability. However, the effect of soil micro-organisms on ecological adaption and rapid growth of woody bamboos remains unclear. Here, 16S rRNA and ITS rRNA genes of rhizosphere micro-organisms were sequenced, and the soil properties of three different types of Dendrocalamus sinicus were determined at the dormancy and germination stages of rhizome buds. The result showed that each type of D. sinicus preferred to absorb ammonia nitrogen (NH₄⁺-N) rather than nitrate nitrogen (NO₃⁻-N) and required more NH₄⁺-N at germination or rapid growth period than during the dormancy period. In total, nitrogen fixation capacity of soil bacteria in the straight type was significantly higher than that in the introduced straight type, while the ureolysis capacity had an opposite trend. Saprophytic fungi were the dominant fungal functional taxa in habitat soils of both straight and introduced straight type. Our findings are of great significance in understanding how soil microbes affect growth and adaptation of woody bamboos, but also for soil management of bamboo forests in red soil. Full article

Effects of Arbuscular Mycorrhizal Fungus on Sodium and Chloride Ion Channels of Casuarina glauca under Salt Stress

Abstract

Casuarina glauca is an important coastal protection forest species, which is exposed to high salt stress all year round. Arbuscular mycorrhizal fungi (AMF) can promote the growth and salt tolerance of C. glauca under salt stress. However, the effects of AMF on the distribution of Na⁺ and Cl⁻ and the expression of related genes in C. glauca under salt stress need to be further explored. This study explored the effects of Rhizophagus irregularis on plant biomass, the distribution of Na⁺ and Cl⁻, and the expression of related genes in C. glauca under NaCl stress through pot simulation experiments. The results revealed that the mechanisms of Na⁺ and Cl⁻ transport of C. glauca under NaCl stress were different. C. glauca took a salt accumulation approach to Na⁺, transferring Na⁺ from roots to shoots. Salt accumulation of Na⁺ promoted by AMF was associated with CgNHX7. The transport mechanism of C. glauca to Cl⁻ might involve salt exclusion rather than salt accumulation, and Cl⁻ was no longer transferred to shoots in large quantities but started to accumulate in roots. However, AMF alleviated Na⁺ and Cl⁻ stress by similar mechanisms. AMF could promote salt dilution of C. glauca by increasing biomass and the content of K⁺, compartmentalizing Na⁺ and Cl⁻ in vacuoles. These processes were associated with the expression of CgNHX1, CgNHX2-1, CgCLCD, CgCLCF, and CgCLCG. Our study will provide a theoretical basis for the application of AMF to improve salt tolerance in plants. Full article

Low Specificity but Dissimilar Mycorrhizal Communities Associating with Roots May Contribute to the Spatial Pattern of Four Co-Occurring Habenaria (Orchidaceae) Species

Abstract

Fungi with orchid roots have been increasingly proven to play important roles in orchid growth, spatial distribution, and coexistence of natural communities. Here, we used 454 amplicon pyrosequencing with two different primer combinations to investigate the spatial variations in the community of OMF and endophytic fungi associates within the roots of four co-occurring Habenaria species. The results showed that all investigated Habenaria species were generalists and the different fungi communities may contribute to the spatial separation of the four Habenaria species. Firstly, the fungal OTUs identified in the roots of the four species overlapped but their presence differed amongst species and numerous distinct OMF families were unique to each species. Second, NMDS clustering showed samples clustered together based on associated species and PERMANOVA analyses indicated that fungi communities in the roots differed significantly between the Habenaria species, both for all endophytic fungi communities and for OMF communities. Third, the network structure of epiphytic fungi was highly specialized and modular but demonstrated lowly connected and anti-nested properties. However, it calls for more soil nutrition and soil fungal communities’ studies to elucidate the contribution of habitat-specific adaptations in general and mycorrhizal divergence. Full article
