    Some Plants May Depend More On Friendly Fungi Than Own Leaves: Study

    Researchers have found that plants need the help of friendly fungi to thrive more than it depends on the quality of its own leaves, and on bacteria that adds nitrogen nutrients to the soil.

    The researchers, including those from the University of Tennessee in the US, found that certain root-associated, or mycorrhizal, fungi that associate firmly with the cells in plant roots are one of the largest influences on plant tissue nutrient concentrations.

    The study, published in the journal PNAS, noted that there are two main types of mycorrhizal fungi—arbuscular and ectomycorrhizal.

    An arbuscular mycorrhiza, the researchers said, penetrates the cells in the outer layer of the roots of a plant.

    Ectomycorrhizal fungi, they said, do not penetrate the plant’s cell walls, instead forming a netlike structure around the plant root.

    According to the researchers, arbuscular mycorrhizal fungi increased plant nutrient concentrations in plant leaves, litter, and roots more than the non-penetrating counterparts, and has more influence on a plant’s nutrient levels than plant leaf traits, or plant associations with nitrogen-fixing bacteria.

    The researchers said that plants live in symbiosis with the root associated fungi which provide up to 80 per cent of the nutrients and water a plant needs to grow.

    They added that up to 30 per cent of the food substance the plants make through photosynthesis is needed by the fungi.

    “To optimize plant nutrition, we need to incorporate mycorrhizal associations into our agricultural and management frameworks,” said study co-author Stephanie Kivlin from the University of Tennessee.

    Demand for mushrooms skyrockets as the West catches up on the rest of the world: Nammex president

    With sales of mushroom containing dietary supplements growing year-on-year by as much as 40%, and food and beverage companies getting in on the act, demand for the fungi has been “unreal”, says Jeff Chilton, President of Nammex Organic Mushroom Extracts.

    France: “It is as if the boletus of the past few years all grew in just one year”

    It is an exceptional campaign for the wild mushroom in terms of volumes in France, according to William Trapon of Trapon Champignons. Especially when it comes to the boletus, which came out of the ground in large numbers. “The last three or four years were difficult because volumes were small. This year, it is as if the boletus of the past few years all grew in just one year.”

    Trapon Champignons commercialized boletus mushrooms non-stop for nearly three months. “It is nice to see this French product again in such large numbers. Besides, the quality is also there.” “Unlike in France, volumes are low in Eastern Europe for this campaign.

    With the arrival of the cold, the boletus slowly comes to an end and Trapon Champignons starts marketing winter products, such as the grey and yellow chanterelles, or the sweet tooth mushroom. “With the rains of the past three weeks, we hope to have an interesting campaign until the end of the year.” Trapon Champignons completes the French production with golden chanterelles from the United States and Canada.

    William claims that there are still a lot of mushrooms in the forests. “When there are a lot of mushrooms in the forests, there is enough for everyone. Many places are inaccessible in the large forests, and I believe that we don’t even pick one tenth of what is out there.”

    Italy’s white truffle hunters worry about climate change

    Rising global temperatures are worrying truffle hunters around in the Italian town of Alba, where the most prized specimens can fetch twice the price of gold.

    The longer-term impact of rising temperatures on the highly prized white truffles is still being studied, but they, like other fungi, grow best in cool, rainy conditions. Climate change has in effect delayed peak production from October into November.

    “It has been a few years that we have been worrying about truffle production,” said Antonio Degiacomi, president of Italy’s national center for truffle studies. “We have had over the last three seasons one terrible year, one excellent season and one that is decent.”

    To stave off the longer-term climate change impact on the production of the highly prized white truffle, experts have launched initiatives to better preserve the territory where they grow. The goal is to safeguard the symbiosis between the truffle and the host plant by encouraging symbiosis between the truffle hunter and the land owner — whose interests often conflict.
