Parasitic plants pose a substantial threat to agriculture as they attack economically important crops. The stem parasitic plant Cuscuta campestris invades the host's stem with a specialized organ referred to as the haustorium, which absorbs nutrients and water from the host. Initiation of the parasitic process in C.

We analyze the proteome changes during the development of the carnauba palm (Copernicia prunifera) seedlings under skotomorphogenic conditions, by separating the embryo into its two components: haustorium (HA) and cotyledonary petiole (CP) and established the descriptive and quantitative proteomes of these tissues across four developmental stages. 5205 proteins were identified in HA and 6028 in CP. These proteomes are rich in proteins known to maintain the skotomorphogenic state, and in a complete set of proteins involved in cellular respiration and biosynthesis of secondary metabolites.

Sugarcane is a major industrial crop highly susceptible to parasitic weed (Striga spp.), causing a 38% reduction in cane yield due to a longer lag phase of 20-40 days, and wider spacing. Herbicides with a longer retention and slow-release nature could allow Striga seeds to germinate and be killed before attaching to the host.

The parasitic mechanism employed by the stem parasitic plant, Cuscuta campestris, involves degradation of the host epidermis and intrusion of the cortical tissue of the host stem by a specialized organ called the haustorium. In host plants, the mechanical stimuli associated with this degradation and intrusion of host tissues is considered to be comparable to wounding. However, it has not yet been clarified whether parasitic invasion and wounding induce equivalent responses in host plants.
