striga/peroxidase

Parasitic strategies within the angiosperms generally succeed by tightly coupling developmental transitions with host recognition signals in a process referred to as xenognosis. Within the Scrophulariaceae, Striga asiatica is among the most studied and best understood parasitic member with respect

BACKGROUND The temporal and spatial control of the transition from vegetative to parasitic growth is critical to any parasite, but is essential to the sessile parasitic plants. It has been proposed that this transition in Striga spp. is controlled simply by an exuded oxidase that converts host

The parasitic witchweed Striga hermonthica causes devastating damage to crops in sub-Saharan Africa, yet the mechanism of its parasitism is not well understood. Parasitic plants form a special organ called a haustorium to obtain water and nutrients from host plants. The haustorium is induced

BACKGROUND In addition to their roles in eukaryotic defense and development, reactive oxygen species (ROS) have recently been identified as critical for host attachment by the parasitic angiosperms. In a process known as semagenesis, ROS generated at the root tip of Striga asiatica (L.) Kuntze
