Transcriptional response of Arabidopsis sweet11/sweet12 double mutants upon Colletotrichum higginsianum infection

ABSTRACT: In compatible interactions, biotrophic microbial phytopathogens rely on the supply of carbon and nitrogen assimilates by the colonized host tissue. Successful biotrophs need to reprogram host metabolism, which also involves the stimulation of assimilate export from living host cells into the plant-pathogen interface at the infection site. In rice and cassava, SWEET sucrose transporters, are induced by bacterial TAL (transcriptional activator-like) effectors to establish compatibility. A pathogen-specific transcriptional induction of SWEET transporters has also been observed in Arabidopsis leaves upon microbial challenge. Here, we have assessed the question, whether the phloem localized AtSWEET11 and AtSWEET12 transporters represent susceptibility factors in the interaction of Arabidopsis w
