This study identifies fss genes that regulate stalked cell morphogenesis and cell cycle progression independently of the flagellum in Caulobacter crescentus.

The paper investigates ALI colonization by freshwater Pararheinheimera bacteria, identifying diverse biofilm architectures including traditional pellicles and buoyant hydrogels.

This study identifies cmrA as a key regulator of hyperadhesion in C. crescentus chemotaxis mutants by recruiting it to the cell pole to activate PleD.

This study identifies the gacSA two-component system as a sensor integrating physical and chemical cues to promote root attachment in Pseudomonas protegens Pf-5.

This study isolates and characterizes Rheinheimera sp. T2C2, a non-pathogenic bacterium capable of effectively biosorbing cobalt, with potential for bioremediation and metal recycling.

This study identifies a deoxyguanosine triphosphate triphosphohydrolase (Dgt) that promotes the G1 to S phase transition by regulating dNTP levels in Caulobacter crescentus.

This paper identifies a flagellar accessory protein, FssF, that links chemotaxis to surface sensing in Caulobacter crescentus, showing it is required for chemotaxis but not swimming motility and contributes to hyperadhesion when chemotaxis is disrupted.

This paper identifies and characterizes a novel bacterial polysaccharide, promonan, and presents methods to manipulate its properties and shorten purification time.
