abstract = {Pesticides are routinely used to prevent severe losses in
agriculture. This practice is under debate because of its
potential negative environmental impact and selection of
resistances in pathogens. Therefore, the development of
disease resistant plants is mandatory. It was shown that the
rice (Oryza sativa) protein OsJAC1 enhances resistance
against different bacterial and fungal plant pathogens in
rice, barley, and wheat. Recently we reported possible
carbohydrate interaction partners for both domains of OsJAC1
(a jacalin-related lectin (JRL) and a dirigent (DIR)
domain), however, a mechanistic understanding of its
function is still lacking. Here, we report crystal
structures for both individual domains and the complex of
galactobiose with the DIR domain, which revealed a new
carbohydrate binding motif for DIR proteins. Docking studies
of the two domains led to a model of the full-length
protein. Our findings offer insights into structure and
binding properties of OsJAC1 and its possible function in
pathogen resistance.},
