Chromatin accessibility profile and the role of PeAtf1 transcription factor in the postharvest pathogen .

Gene transcription is governed by a complex regulatory system involving changes in chromatin structure, the action of transcription factors, and the activation of -regulatory elements. Postharvest fruits are threatened by , a leading causal agent of blue mold disease and one of the most economically significant postharvest pathogens worldwide. However, information on its transcription regulatory mechanism is lagging.

Nickel-Catalyzed Direct Fluorosulfonylation of Vinyl Bromides and Benzyl Bromides for Sulfonyl Fluorides.

An efficient nickel-catalyzed direct fluorosulfonylation of vinyl bromides and benzyl bromides under mild reaction conditions has been developed for sulfonyl fluorides utilizing NaSO and NFSI as the sulfur dioxide and fluorine sources, respectively. This reaction system tolerates organic bromide compounds, such as β-styryl bromides, alkyl vinyl bromides, and benzyl bromides, to achieve corresponding sulfonyl fluorides in moderate to good yields, with convenient operation, mild conditions, broad substrate scope, good functional group compatibility, and excellent retention of configuration to vinyl bromides.

Stereoselective Fluorosulfonylation of Vinylboronic Acids for ()-Vinyl Sulfonyl Fluorides with Copper Participation.

A practical synthetic method for the synthesis of vinyl sulfonyl fluorides through copper-promoted direct fluorosulfonylation has been developed. The reaction of the vinylboronic acids with DABSO and then NFSI is performed under mild reaction conditions. This transformation efficiently affords aryl or alkyl vinyl sulfonyl fluorides with good reaction yields, exclusive -configuration, broad substrate scope, excellent compatibility, and operational simplicity.

Study on the control effect and physiological mechanism of Wickerhamomyces anomalus on primary postharvest diseases of peach fruit.

Brown rot, aspergillosis and soft rot are the primary diseases of postharvest peach fruit. Our study aimed to investigate the biocontrol effect of Wickerhamomyces anomalus on the primary postharvest diseases of peach fruit and to explore its underlying physiological mechanism. The findings demonstrated that W.
