Special Issue Information

Dear Colleagues,

The upcoming Special Issue aims to delve into the diverse influence of beneficial plant-associated microbes on host plants, elucidating their pivotal roles in enhancing plant health, growth, and stress resilience. This issue seeks to highlight the multifaceted effects these symbiotic organisms exert on their hosts, including enhanced nutrient uptake, improved pathogen resistance, and mitigation of abiotic stressors such as drought and salinity.

Furthermore, research has revealed that these interactions extend to the modulation of plant hormone levels, positively influencing developmental processes and overall fitness. Additionally, these associations impact the host's immune system, contributing to improved defense mechanisms, while some microbes produce bioactive compounds with potential pharmaceutical and agricultural applications.

We invite contributions that delve into the intricate mechanisms by which beneficial plant-associated microbes affect host plants, whether related to the ecological dynamics underlying these interactions, the molecular basis of symbiosis, or the practical implications for sustainable agriculture. By fostering collaborative insights and advancements in this area, we aim to pave the way for innovative strategies harnessing the beneficial effects of plant-associated microbes, ultimately leading to enhanced plant health and agricultural sustainability.

Orchids are crucial for the horticulture industry. Mycorrhizal fungi benefit crops by improving nutrition, plant growth, and disease resistance. However, the mycorrhizal association of horticultural hybrid orchids is poorly understood. To address this, we investigated mycorrhizal colonization in the entire root system and assessed the mycorrhizal community using a Dendrobium cultivar, D. Stardust ‘Firebird’, obtained from three nurseries. Additionally, we isolated and tested mycorrhizal fungi in symbiotic culture to assess their role in the seed germination and growth of Dendrobium species. All plants were colonized by mycorrhizal fungi, with a higher colonization rate in mature than in juvenile plants. Molecular identification of mycorrhizal fungi by Sanger and high-throughput sequencing revealed that the cultivar was associated with a phylogenetically diverse group of fungi, including mycorrhizal fungi from Tulasnellaceae, and several wood-decaying fungi. The Tulasnellaceae isolates significantly enhanced the seed germination of three Dendrobium species and increased the survival rate and growth of asymbiotic seedlings of D. moniliforme. This study is the first comprehensive examination of mycorrhizal associations in horticultural orchid hybrids, providing valuable insights for commercial production. Full article

The use of endophytic microbes is increasing in commercial agriculture. This review will begin with a strain selection. Most strains will not function well, so only a few provide adequate performance. It will also describe the endophyte–plant relationship and the fungi and bacteria involved. Their abilities to alleviate biotic (diseases and pests) and abiotic stresses (drought, salt, and flooding) to remediate pollution and increase photosynthetic capabilities will be described. Their mechanisms of action will be elucidated. These frequently result in increased plant yields. Finally, methods and practices for formulation and commercial use will be described. Full article
