WebJul 22, 2024 · GTRC encodes a processive minus-end-directed KCHb kinesin, and its N-terminal, C-terminal and motor domains are all essential for transducing the gravity signal. Chimeric analysis between GTRC/KCHb and KCHa reveal a unique role for the N-terminus of GTRC in gravitropism. Further study shows that gravity-triggered normal asymmetric … http://dictionary.sensagent.com/gravitropism/en-en/

Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it. It also occurs in fungi. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms. Charles Darwin … See more Root growth occurs by division of stem cells in the root meristem located in the tip of the root, and the subsequent asymmetric expansion of cells in a shoot-ward region to the tip known as the elongation zone. … See more Statoliths Plants possess the ability to sense gravity in several ways, one of which is through statoliths. Statoliths are dense amyloplasts, organelles that … See more Bending mushroom stems follow some regularities that are not common in plants. After turning into horizontal the normal vertical orientation the apical part (region C in the figure below) starts to straighten. Finally this part gets straight again, and the curvature … See more Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are … See more A few species of fruit exhibit negative geotropism. Bananas are one well-known example. Once the canopy that covers the fruit dries, the bananas will begin to curve upwards, towards sunlight, in what is known as phototropism. The specific chemical that … See more Mutants with altered responses to gravity have been isolated in several plant species including Arabidopsis thaliana (one of the genetic model systems used for plant research). … See more • Amyloplast – starch organelle involved in sensing gravitropism • Astrobotany – the field of science concerned with plants in a spaceflight environment • Clinostat – a device used to the effects of gravitational pull See more himalaya l size diaper
