Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

Advanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

Magnetic Properties of Melanin Doped with Copper Oxide Nanoparticles

Engineering Proceedings
In this study, the analysis of XRD patterns reveals that both natural melanin and copper oxide-doped melanin exhibit amorphous structures. The absence of new peaks for Cu2O confirms that the copper oxide nanoparticles are effectively integrated into the ...

CsdA‐LaeB Regulatory Hub Contributes to Aspergillus fumigatus Virulence via Fumiquinazoline C Biosynthesis

Advanced Science, EarlyView.
This study identifies a conserved CsdA‐LaeB hub in Aspergillus fumigatus that regulates secondary metabolite fumiquinazoline C (FqC). Disrupting this hub enhances FqC production and virulence, shedding new light on the post‐transcriptional regulatory logic linking secondary metabolism to pathogenicity and offering alternative strategies for diagnostic ...

Bacterial melanin promotes recovery after sciatic nerve injury in rats

Neural Regeneration Research, 2015
Bacterial melanin, obtained from the mutant strain of Bacillus Thuringiensis, has been shown to promote recovery after central nervous system injury. It is hypothesized, in this study, that bacterial melanin can promote structural and functional recovery
