MAX4 and RMS1 are orthologous dioxygenase-like genes that regulate shoot branching in Arabidopsis and pea (2003)

Sorefan, Karim, Booker, Jon, Haurogne, Karine, Goussot, Magali, Bainbridge, Katherine, Foo, Eloise, ...

Shoot branching is inhibited by auxin transported down the stem from the shoot apex. Auxin does not accumulate in inhibited buds and so must act indirectly. We show that mutations in the MAX4 gene of...

Oral Vaccination against Tetanus: Comparison of the Immunogenicities of Salmonella Strains Expressing Fragment C from the nirB and htrA Promoters

Roberts, Mark, Li, Jingli, Bacon, Andrew, Chatfield, Steven

Prior Immunity to Homologous and Heterologous Salmonella Serotypes Suppresses Local and Systemic Anti-Fragment C Antibody Responses and Protection from Tetanus Toxin in Mice Immunized with Salmonella Strains Expressing Fragment C

Roberts, Mark, Bacon, Andrew, Li, Jingli, Chatfield, Steven

We have investigated the effect of preexisting immunity to homologous (Salmonella typhimurium) or heterologous (S. dublin) serotypes of Salmonella on the ability of an attenuated S. typhimurium aroA...

Comparison of Abilities of Salmonella enterica Serovar Typhimurium aroA aroD and aroA htrA Mutants To Act as Live Vectors

Roberts, Mark, Chatfield, Steven, Pickard, Derek, Li, Jingli, Bacon, Andrew

We compared the ability of Salmonella enterica serovar Typhimurium SL1344 aroA aroD (BRD509) and aroA htrA (BRD807) mutants to act as live vectors for delivery of fragment C of tetanus toxin (FrgC)....

Oral Vaccination against Tetanus: Comparison of the Immunogenicities of Salmonella Strains Expressing Fragment C from the nirB and htrA Promoters

Roberts, Mark, Li, Jingli, Bacon, Andrew, Chatfield, Steven

We have found the in vivo-regulated nirB promoter (PnirB) to be effective for directing expression of a number of antigens in salmonella in vivo. We wished to determine if other in vivo-regulated...

Auxin Acts in Xylem-Associated or Medullary Cells to Mediate Apical Dominance

Booker, Jonathan, Chatfield, Steven, Leyser, Ottoline

A role for auxin in the regulation of shoot branching was described originally in the Thimann and Skoog model, which proposes that apically derived auxin is transported basipetally directly into the...
