chemotropism
noun
A tropism, especially of a plant, in response to a particular substance.Studies of chemotropism in yeast revealed important differences in the identity of the sensory pathways involved in gradient sensing in D. discoideum and Saccharomyces cerevisiae....
- But the notion of chemotropism came to fruition only a decade later in the context of nerve regeneration.
- Here a complicated set of tropisms is involved from thigmotropism, or response to touch when the insect lights on the leaf, to a chemotropism in the secreting of digestive juices.
Derivatives
chemotropic
- A computational account of these results is proposed, based on a unified model that combines chemotropic gradients and spike-time-dependent synaptic plasticity.
- Inhibition of this local protein synthesis blocks the turning responses of growth cones in a chemotropic gradient suggesting that local synthesis is involved in directional steering.
- Although they have been shown to function in nerve growth cones, the new studies [1,2] are the first to demonstrate that they have a role in chemotropic axon guidance.
chemotropically
- Hunger, for example, calls out motion through changes produced by katabolism in the organism, whereby it is attracted chemotropically to food.
- Upon germination, broomrape seeds develop a small radicle that grows chemotropically towards host roots and firmly connects to a host rootlet.
- If the axon reorients towards or away from the pipette it suggests that the molecule acts chemotropically to influence axon behavior.
