Fungal symbiont Mycena complements impaired nitrogen utilization in Gastrodia elata and supplies indole-3-acetic acid to facilitate its seed germination

A special type of orchid called Gastrodia elata cannot survive on its own because it has lost the ability to produce its own food and certain plant growth hormones. Instead, it relies completely on a fungal partner called Mycena to provide nitrogen nutrients and auxin (a growth hormone). This study reveals exactly how Mycena does this by analyzing their genes and how they communicate, showing that the fungus acts as a nutritional life-support system for the orchid seed’s germination.

Effects of Isaria cateniannulata on the colonization process and enzyme activity of Fagopyrum tataricum seeds during germination

Researchers discovered that a beneficial fungus called Isaria cateniannulata can colonize buckwheat seeds and improve their germination. When seeds are treated with this fungus, it enters the seed tissues and strengthens the plant’s natural defenses against stress. The treated plants are also more resistant to spider mites, reducing the number of eggs these pests lay. This offers a natural, chemical-free way to improve seed germination and protect crops from harmful insects.

Researchers discovered that a special fungus called Isaria cateniannulata can successfully colonize buckwheat seeds and promote their germination. When seeds are treated with this fungus, the resulting plants produce more protective enzymes that reduce damage from oxidative stress. Additionally, plants grown from fungus-treated seeds are more resistant to spider mites, laying fewer eggs and reducing pest populations. This discovery offers a natural, biotechnology-based approach to improve seed germination and pest control in buckwheat farming.

Gastrodia elata is a special orchid that cannot make its own food and must rely entirely on a fungal partner called Mycena. Scientists discovered that the orchid has lost genes needed to use nitrogen and make growth hormones, while the fungus Mycena has kept these genes. By providing nitrogen and a hormone called auxin, the fungus helps the orchid seeds germinate and grow.

Isolation and identification of antagonistic fungi for biocontrol of Impatiens hawkeri leaf spot disease and their growth-promoting potential

Researchers discovered a beneficial fungus called Fusarium solani that prevents leaf spot disease in ornamental Impatiens hawkeri plants. This fungus not only fights the disease-causing pathogen but also promotes seed germination and plant growth. The findings suggest this fungus could replace harmful chemical pesticides while simultaneously acting as a natural fertilizer, benefiting both plant health and the environment.
