Host-plant recognition by parasitic Scrophulariaceae.
Parasitic plants in the Scrophulariaceae invade the roots of neighboring plants in order to rob them of water and nutrients. A distinctive feature of these parasites is their ability to cue their development to small molecules released by host-plant roots. Evidence is continuing to emerge that parasite perception of host factors occurs via a redox-associated mechanism. Genes predicted to functi...
متن کاملMolecular Parasitic Plant–Host Interactions
Throughout evolution, a wide number of organisms specialized in parasitizing plants. Plants are not exceptions; certain plant species evolved as parasites of their own kind. Parasitic angiosperms evolved at least 12 times and show various lifestyles. For example, facultative parasitic plants can complete their life cycle and produce seeds without hosts, whereas obligate parasitic plants totally...
متن کاملHost plant finding by insects - undersowing crop plants with clover reveals the missing link
Characteristic volatile chemicals are credited with the major role of guiding herbivorous insects to their host plants. Studies comparing how insects find host plants growing in backgrounds of clover and bare soil indicated that it is not chemical, but visual stimuli that govern where the insects land. A mechanism of hostplant finding is proposed in which chemical cues start and end the process...
متن کاملSuppression of host photosynthesis by the parasitic plant Rhinanthus minor.
BACKGROUND AND AIMS Parasitism is well understood to have wide-ranging deleterious effects on host performance in species thus far characterized. Photosynthetic performance reductions have been noted in the Striga-Zea mays association; however, no such information exists for facultative hemiparasitic plants and their hosts, nor are the effects of host species understood. METHODS Chlorophyll f...
متن کاملCross-species translocation of mRNA from host plants into the parasitic plant dodder.
An intriguing new paradigm in plant biology is that systemically mobile mRNAs play a role in coordinating development. In this process, specific mRNAs are loaded into the phloem transport stream for translocation to distant tissues, where they may impact on developmental processes. However, despite its potential significance for plant growth regulation, mRNA trafficking remains poorly understoo...
