Abstract The pathogen Moliniophthora perniciosa can cause losses in the cocoa crop of more than 90% when integrated disease management is not carried out crop. In present study, effect sucrose as a resistance inducer trees ( Theobroma cacao L.), was evaluated for “witches’ broom” caused by Moniliophthora . experiment developed municipality Chaparral, Tolima, Colombia (854 m.a.s.l.). treatments ...

Signal transduction ATPases with numerous domains (STAND) get activated through inducer-dependent assembly into multimeric platforms. This switch relies on the conversion of their nucleotide-binding oligomerization domain (NOD) from a closed, ADP-bound form to an open, ATP-bound form. The NOD closed form is stabilized by contacts with the arm, a domain that connects the NOD to the inducer-bindi...

Previous studies established the critical roles of AlcR and alcaligin inducer in positive regulation of alcaligin siderophore biosynthesis and transport genes in Bordetella pertussis and Bordetella bronchiseptica. Transcriptional analyses using plasmid-borne alcR genes of B. pertussis UT25 and B. bronchiseptica B013N to complement the alcR defect of B. bronchiseptica strain BRM13 (Delta alcR1 a...

BACKGROUND The E. coli lac operon and its components have been studied for decades, and lac-derived systems are widely used for recombinant protein production. However, lac operon dynamics and induction behavior remain the paradigm of gene regulation. Recently, an HPLC-MS-based method to quantify IPTG in the medium and inside the biomass has been established, and this tool may be useful to unco...
