Tropisms make up the abilities that are essential to plants and every living thing. Because plants are able to adjust to the conditions around them, a plant's actual configuration and growth can be altered by tropisms. A tropism is the response to an exter...
The meaning of TROPISM is involuntary orientation by an organism or one of its parts that involves turning or curving by movement or by differential growth and is a positive or negative response to a source of stimulation. How to use tropism in a sentenc
Mutants in three loci (, , and ) that are essential for the establishment of normal phototropic responses have been characterized in detail. Complete loss-of-function mutations in the locus eliminate the phototropic response to directional UV-A/blue/green light cues (1). Recent cloning of the...

Plants will be an important component in bioregenerative systems for long-term missions to the Moon and Mars. Since gravity is reduced both on the Moon and Mars, studies that identify the basic mechanisms of plant growth and development in altered gravity are required to ensure successful plant ...
From the very beginnings, attempts to identify mechanisms underlying polar auxin transport in higher plants have been intimately linked to studies on the regulation of plant tropisms. Already in the nineteenth century Charles Darwin came up with a concept, suggesting that a transmissible signal might ...
In contrast, in blue-light-based phototropism, DIS1 attenuated the response in hypocotyls of dark-grown seedlings and in red-light-based positive phototropism in roots. Taken together, these studies are the first to suggest that the ARP 2/3 complex, a major family of actin-binding proteins, ...
elegans to light is very quick and hydrogen peroxide is immediately generated upon illumination (see the Fig.5 in1). This finding provides important implication for researchers to be careful to consider light response of living organisms. In case of plants, root organs are growing under the ...
