Innovative fungal bioagents: producing siderophores, IAA, and HCN to support plants under salinity stress and combat microbial plant pathogens

mycolabadmin

Scientists discovered two beneficial fungi that help wheat plants survive in salty soil and resist diseases. These fungi work by producing growth-promoting substances and natural compounds that fight harmful plant pathogens. When used to treat wheat seeds, these fungi significantly improved plant growth even under high salt stress conditions, offering a natural alternative to chemical fertilizers and pesticides for farming in salt-affected areas.

Genome-wide identification of PSKR genes in wheat and differential expression under abiotic stress conditions

mycolabadmin

Scientists identified 149 genes related to phytosulfokine receptors (PSKR) in wheat that help plants respond to environmental stresses like drought, salt, cold, and heat. These genes are spread across wheat’s chromosomes and contain regulatory elements that control their expression in response to various stresses and plant hormones. The study provides important genetic resources for developing wheat varieties that are more resistant to environmental stress, which is crucial for maintaining crop productivity in changing climate conditions.

The Small Key to the Treasure Chest: Endogenous Plant Peptides Involved in Symbiotic Interactions

mycolabadmin

Plants use tiny signaling molecules called peptides to communicate with beneficial soil organisms like nitrogen-fixing bacteria and fungi. These peptides act like chemical messengers that help plants decide when to allow these microbes to enter their roots and form helpful relationships. The review identifies over a dozen peptide families that control nodule formation, nutrient uptake, and immune responses, revealing how plants have evolved sophisticated mechanisms to balance protection against harmful pathogens while welcoming beneficial partners.

Phytohormones and volatile organic compounds, like geosmin, in the ectomycorrhiza of Tricholoma vaccinum and Norway spruce (Picea abies)

mycolabadmin

This research examines how a fungus (Tricholoma vaccinum) and spruce tree communicate through chemical signals. The fungus produces unique compounds including geosmin (the earthy smell of soil after rain), limonene (lemon scent), and plant hormones. These chemicals help the fungus and tree establish their beneficial partnership by affecting how the fungus grows and branches around the tree roots. The findings show that these chemical signals are crucial for successful formation of the mycorrhizal relationship.

The Biocontrol and Growth-Promoting Potential of Penicillium spp. and Trichoderma spp. in Sustainable Agriculture

mycolabadmin

This review examines how two types of beneficial fungi, Penicillium and Trichoderma, can improve crop growth and protect plants from diseases without using chemical pesticides. These fungi work by colonizing plant roots, producing natural compounds that boost plant health, and fighting harmful pathogens. They are affordable, safe, and environmentally friendly alternatives for sustainable farming that can increase yields while reducing the need for synthetic fertilizers and fungicides.

Melatonin-Producing Microorganisms: A Rising Research Interest in Their Melatonin Biosynthesis and Effects on Crops

mycolabadmin

Scientists are discovering that certain microorganisms like yeast, algae, and bacteria naturally produce melatonin, the same molecule that helps humans sleep. These melatonin-producing microbes could help farmers grow healthier crops by sharing their melatonin with plants and protecting them from stress like drought and disease. This discovery offers an eco-friendly alternative to synthetic melatonin and could make agriculture more sustainable as climate change poses increasing challenges.

Alliance Between Conifer Trees and Endophytic Fungi Against Insect Defoliators

mycolabadmin

Researchers discovered that helpful fungi living inside white spruce needles protect the trees from damaging budworm insects. These fungi work in two ways: they directly poison the insects that try to eat the needles, and they also encourage the trees to produce more of their own chemical defenses. This partnership between fungi and trees demonstrates an important co-evolutionary relationship where all three organisms—fungi, trees, and insects—influence each other over time.

The Biocontrol and Growth-Promoting Potential of Penicillium spp. and Trichoderma spp. in Sustainable Agriculture

mycolabadmin

This review explores how two common fungi, Penicillium and Trichoderma, can help crops grow better and resist diseases naturally. These beneficial fungi live in plant roots and soil, providing nutrients, protecting against harmful pathogens, and helping plants cope with environmental stress. They offer an environmentally friendly alternative to chemical pesticides and fertilizers, making them valuable for sustainable agriculture.

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

mycolabadmin

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.
