Mechanism of zju‐miR156c‐mediated network in regulating witches' broom symptom of Chinese jujube

Molecular Plant Pathology, Volume 25, Issue 11, November 2024.
The SJP1JWB‐ZjERF18‐zju‐miR156c‐ZjSPL3‐CTK regulatory pathway functions importantly in the formation of witches' broom. Abstract Jujube witches' broom, caused by phytoplasma, is a destructive disease of Chinese jujube. Studies have shown that zju‐miR156s play an important role in phytoplasma infection in jujube, but the regulatory mechanism between zju‐

Past, present and future of glycolipids from Ustilaginaceae – A review on cellobiose lipids and mannosylerythritol lipids

Journal of Surfactants and Detergents, Volume 27, Issue 5, Page 647-689, September 2024.
Abstract The glycolipids cellobiose lipids (CL) and mannosylerythritol lipids (MEL) are biosurfactants mainly synthesized by microorganisms of the Ustilaginaceae family. They have a large structural diversity, varying in their sugar moieties and the attached fatty acids, resulting in a prospectively broad range of applications.
