The rice false smut disease, caused by Ustilaginoidea virens, has emerged as a significantglobal threat to rice production. The mechanism of carbon catabolite repression plays a crucial role in theeffic.ent utilization of carbon nutrients and enzyme regulation in the presence of complex nutritionalconditions. Although significant progress has been made in understanding carbon catabolite repression infungi such as Aspergillus nidulans and Magnaporthe oryzae, its role in U. virens remains unclear. Toaddress this knowledge gap, we identified UvcreA, a pivotal component of carbon catabolite repression,in U. virens. Our investigation revealed that UvcreA localized to the nucleus. Deletion of UvcreA resultedin decreased growth and pathogenicity in U. virens. Through RNA-seq analysis, it was found that theknockout of UvcreA led to the up-regulation of 514 genes and down-regulation of 640 genes. Moreover,UvcreA was found to be involved in the transcriptional regulation of pathogenic genes and genesassociated with carbon metabolism in U. virens. In summary, our findings indicated that UvcreA isimportant in fungal development, virulence, and the utilization of carbon sources through transcriptionalregulation, thus making it a critical element of carbon catabolite repression.

Photocatalytic conversion of cO_(2) into small-molecule chemical feedstocks can meet the growing demand for energy and alleviate the global warming. Herein, a p-n ZnO@cDs@co_(3)O_(4) heterojunction with sandwich structure was constructed by calcination method of self-assembled ZIF-8@cDs@ZIF-67. The ZnO@cDs@co_(3)O_(4) with well-defined interfacial structure exhibited the significantly enhanced photocatalytic cO_(2) reduction activity, and the optimal catalyst indicated the(cO + cH_(4)) evolution rate of 214.53μmol g^(-1)h^(-1) under simulated solar light, which was superior to ZnO, co_(3)O_(4) and binary ZnO@co_(3)O_(4).The internal cavity, exposed active sites, multiple interfaces and constructed p-n heterojunction can facilitate the light harvesting and photoexcited electron transfer. Besides, after introduction of cDs placed in the middle layer between ZnO and co_(3)O_(4), cDs with excellent photoelectric property further promoted charge separation and migration. This work represents an appealing strategy to construct well-defined photocatalysts for boosting cO_(2) photoreduction.
