Ustilaginoidin D Induces Acute Toxicity and Hepatotoxicity in Mice. [PDF]

Toxins (Basel)
Ustilaginoidin D is a type of bis-naphtho-γ-pyrone mycotoxin produced by Ustilaginoidea virens, the causal agent of rice false smut. Although previous studies have demonstrated the inhibitory effect of ustilaginoidin D on ATP synthesis and cancer cell growth in mice, its specific health risks remain unclear.

An Ustilaginoidea virens glycoside hydrolase 42 protein is an essential virulence factor and elicits plant immunity as a PAMP

Molecular Plant Pathology, Volume 24, Issue 11, Page 1414-1429, November 2023., 2023
UvGHF1, as a GH42‐type glycosyl hydrolase secreted by Ustilaginoidea virens, contributes to U. virens virulence, whereas it is recognized by the rice surveillance system to trigger plant immunity. Abstract Rice false smut, caused by the ascomycete fungus Ustilaginoidea virens, which infects rice florets before heading, severely threatens rice grain ...

Recent advances of nanobody applications in diagnosis and detection

MedComm – Biomaterials and Applications, Volume 2, Issue 3, September 2023., 2023
Nanobodies (Nbs) are the variable domain of heavy‐chain antibodies derived from the blood of camelids or sharks. In this review, we summarize recent advances in the discovery and production of novel nanobodies, and their use in detection and diagnosis platforms.

A Common C2‐Symmetric 2,2’‐Biphenol Building Block and its Application in the Synthesis of (+)‐di‐epi‐Gonytolide A

Chemistry – A European Journal, Volume 29, Issue 34, June 19, 2023., 2023
An axially chiral biphenol with a common biaryl polyketide motif was investigated. The versatile building block was made accessible by a streamlined synthesis featuring an efficient coupling procedure as well as a DFT‐rationalized starting material bromination and thermodynamically controlled deracemization process. An application was demonstrated in a

The essential effector SCRE1 in Ustilaginoidea virens suppresses rice immunity via a small peptide region

Molecular Plant Pathology, Volume 21, Issue 4, Page 445-459, April 2020., 2020
The Ustilaginoidea virens effector SCRE1 can suppress plant immunity and promote disease development in rice and a novel small peptide region is identified to be essential for SCRE1 immunosuppressive ability. Summary The biotrophic fungal pathogen Ustilaginoidea virens causes rice false smut, a newly emerging plant disease that has become epidemic ...

The false smut pathogen Ustilaginoidea virens requires rice stamens for false smut ball formation

Environmental Microbiology, Volume 22, Issue 2, Page 646-659, February 2020., 2020
Summary Rice false smut has emerged as a serious grain disease in rice production worldwide. The disease is characterized by the transformation of individual rice florets into false smut balls, which is caused by the fungal pathogen Ustilaginoidea virens.
