Aposematic (Warning) Coloration in Plants
Aposematic (warning) coloration is a common defense in plants, although it was largely ignored before 2001. The fact that many aposematic animals use both plant-based pigments and sequestered poisonous molecules to become aposematic emphasizes the absurdity of neglecting the aposematic nature of so many plants. Similar to the situation in animals, aposematic coloration in plants is commonly yel...
متن کاملAposematic (warning) coloration associated with thorns in higher plants.
Aposematic coloration, a well-known phenomenon in animals, has been given little attention in plants. Here I discuss two types of conspicuousness of thorns which are typical of many plant species: (1) colorful thorns, and (2) white spots, or white and colorful stripes, associated with thorns in leaves and stems. Both types of aposematic coloration predominate the spine system of taxa rich with ...
متن کاملParasitic plants of the genus Cuscuta and their interaction with susceptible and resistant host plants
By comparison with plant-microbe interaction, little is known about the interaction of parasitic plants with their hosts. Plants of the genus Cuscuta belong to the family of Cuscutaceae and comprise about 200 species, all of which live as stem holoparasites on other plants. Cuscuta spp. possess no roots nor fully expanded leaves and the vegetative portion appears to be a stem only. The parasite...
متن کاملTrans-specific gene silencing between host and parasitic plants.
Species of Orobanchaceae parasitize the roots of nearby host plants to rob them of water and other nutrients. Parasitism can be debilitating to the host plant, and some of the world's most pernicious agricultural pests are parasitic weeds. We demonstrate here that interfering hairpin constructs transformed into host plants can silence expression of the targeted genes in the parasite. Transgenic...
متن کاملVolatile chemical cues guide host location and host selection by parasitic plants.
The importance of plant volatiles in mediating interactions between plant species is much debated. Here, we demonstrate that the parasitic plant Cuscuta pentagona (dodder) uses volatile cues for host location. Cuscuta pentagona seedlings exhibit directed growth toward nearby tomato plants (Lycopersicon esculentum) and toward extracted tomato-plant volatiles presented in the absence of other cue...
