Impact of the facultative parasitic weed Rhamphicarpa fistulosa (Hochst.) Benth. on photosynthesis of its host Oryza sativa L.

In a new paper, published in Journal of Plant Physiology ( we show that leaf photosynthesis and a range of associated parameters is heavily impacted in rice plants when they are infected by the facultative parasitic weed Rhamphicarpa fistulosa. Previously we found that this parasite starts benefiting from its host at around 6 weeks after sowing. Here we show that the parasite effects on host plant physiology start about 2 weeks after this. With obligate parasitic plants, such as Striga spp. , these effects appear much earlier.
