Global Analysis of microRNA-like RNAs Reveals Differential Regulation of Pathogenicity and Development in Fusarium oxysporum HS2 Causing Apple Replant Disease

mycolabadmin

Apple replant disease is caused by a fungus that damages apple tree roots and reduces fruit production. Researchers discovered that this fungus uses special regulatory molecules called microRNA-like RNAs to control its growth and disease-causing abilities, especially during the spore stage. These findings could help scientists develop new ways to control the disease using RNA-based treatments.

Argonaute1-Dependent LtmilR2 Negatively Regulated Infection of Lasiodiplodia theobromae by Targeting a Guanine Nucleotide Exchange Factor in RAS Signalling

mycolabadmin

Scientists discovered a small RNA molecule called LtmilR2 in a fungus that causes grape canker disease. This molecule naturally suppresses the fungus’s ability to infect grapes. By delivering this molecule or similar RNA duplexes to the fungus, researchers were able to inhibit its growth and infection, suggesting a new type of biological fungicide that could protect vineyards without chemical pesticides.
