Cytophysiological manifestations of wheat’s defense reactions against stem rust induced by the biofungicide Novochizol

mycolabadmin

Scientists studied how a new plant-based product called Novochizol helps wheat plants defend themselves against stem rust, a destructive fungal disease. When wheat seedlings were treated with Novochizol before being exposed to the rust fungus, the plants showed strong defensive reactions including increased production of protective hydrogen peroxide and phenolic compounds. The treatment significantly reduced the number and size of rust pustules (infection spots) on susceptible wheat plants, effectively converting them to a more resistant state without harming the plants.

Elucidation of Twig Canker and Shoot Blight (TCSB) in Peach Caused by Diaporthe amygdali in the North of Italy in Emilia-Romagna

mycolabadmin

Peach trees in northern Italy are suffering from a disease called twig canker and shoot blight caused by a fungus called Diaporthe amygdali. This research identified and characterized this fungus from affected orchards, studying how it grows at different temperatures to better understand and control the disease. The fungus grows best around 23-24°C and can survive extreme heat above 50°C. These findings will help fruit growers develop better strategies to protect their peach crops.

Biocontrol Potential of a Mango-Derived Weissella paramesenteroides and Its Application in Managing Strawberry Postharvest Disease

mycolabadmin

Researchers discovered a beneficial bacterium called Weissella paramesenteroides that naturally lives on mango fruit and can protect strawberries from fungal diseases during storage. The bacterium works by releasing special chemicals in the air called volatile organic compounds that prevent mold growth without direct contact. This provides a natural, food-safe alternative to synthetic fungicides for keeping fresh fruit fresher longer.

Identifying Key Pathogens and Effective Control Agents for Astragalus membranaceus var. mongholicus Root Rot

mycolabadmin

Astragalus root, a valued traditional Chinese medicine, suffers from a serious fungal disease caused primarily by two Fusarium species. Researchers tested eight fungicides and nine beneficial bacteria to find the most effective treatments. The chemical fungicide carbendazim and a beneficial bacterium called KRS006 proved most effective, offering promise for developing better disease management strategies that combine both chemical and biological approaches.

Biological and Genomic Insights into Fusarium acuminatum Causing Needle Blight in Pinus tabuliformis

mycolabadmin

Researchers identified a fungus called Fusarium acuminatum as the cause of needle blight disease affecting Chinese pine trees in northern China. They studied how this fungus grows and sequenced its entire genome to understand how it damages the trees. The findings help explain the disease and provide tools to develop better ways to protect and treat infected pine trees.

Thermotolerance and post-fire growth in Rhizina undulata is associated with the expansion of heat stress-related protein families

mycolabadmin

Rhizina undulata is a fungus that infects conifer trees and uniquely relies on the heat from forest fires to wake up and start growing. Scientists sequenced the fungus’s DNA and discovered it has extra copies of genes that help it survive extreme heat, deal with harmful molecules created by heat stress, and digest burned plant material. These genetic adaptations explain how this fungus has evolved to take advantage of fire events for its survival and spread.

Inhibition of RNase to Attenuate Fungal-Manipulated Rhizosphere Microbiome and Diseases

mycolabadmin

A fungal pathogen that causes root rot in soybeans and other crops uses a toxic protein called Fg12 to kill beneficial bacteria in the soil that would otherwise protect plants. Scientists discovered that guanosine monophosphate (GMP), a simple chemical compound, can block this toxic protein. When applied to soil, GMP protects plants by allowing beneficial bacteria to survive and fight the fungal infection.

Colletotrichum scovillei and Prospective Biocontrol Agents Isolated from Asymptomatic Olive Trees

mycolabadmin

Researchers discovered that olive trees in Greece naturally harbor several species of fungi, including a newly identified disease-causing fungus called Colletotrichum scovillei. More importantly, they found that other fungi living harmlessly inside the olive tissue can protect the plant by fighting against the harmful fungi. Two of these protective fungi, KORD1f and KORD4f, reduced olive anthracnose disease symptoms by 67-73%, suggesting they could be used as natural alternatives to chemical fungicides for olive disease management.

Inhibition of RNase to Attenuate Fungal-Manipulated Rhizosphere Microbiome and Diseases

mycolabadmin

Fusarium fungi cause devastating crop diseases by producing a protein called Fg12 that acts like a molecular weapon to kill beneficial bacteria in the soil around plant roots. Scientists discovered that a simple compound called GMP can block this fungal weapon, preventing the pathogen from suppressing protective bacteria. By treating seeds or soil with GMP, farmers can significantly reduce root rot in soybeans and alfalfa while promoting plant growth.

Genome sequencing and analysis of isolates of Cytospora sorbicola and Cytospora plurivora associated with almond and peach canker

mycolabadmin

Scientists have sequenced the complete genetic code of two fungal species that cause destructive canker diseases in almond and peach trees. These fungi are difficult to control once they infect trees, and developing disease-resistant plant varieties is the best approach to protect orchards. The genetic information from this study will help researchers understand how these fungi cause disease and develop better strategies to breed resistant fruit trees.
