WitrynaPlants being sessile can often be judged as passive acceptors of their environment. However, plants are actually even more active in responding to the factors WitrynaGravitropism. This process is the movement of the plant in response to the gravitational pull of the earth. Gravitropism is also known as geotropism. This phenomenon can also be achieved by artificial gravity. That is why the study of gravitropism also finds its application in growing plants in space. Role of Auxin in Gravitropism

Witryna17 gru 2003 · Given the variety of plant responses regulated by Ca 2+, it is not surprising that its role in gravitropism has been a favorite topic of research for many years. Although its involvement in gravitropism has not been defined clearly, there have been some interesting developments since the last Update (Chen et al., 1999), which we … WitrynaAbstract. The models explaining root gravitropism propose that the growth response of plants to gravity is regulated by asymmetric distribution of auxin (indole-3-acetic acid, IAA). Since cytokinin has a negative regulatory role in root growth, we suspected that it might function as an inhibitor of tropic root elongation during gravity response.
