Plant tropisms: From Darwin to the International Space Station

WebAnother commonly observed tropic responses is gravitropism, where a plant will grow so that it stays oriented relative to the source of gravity (the earth). Thus, if a plant is knocked down the shoot will grow faster on the lower side until the shoot is more-or-less standing up again. Tropic responses result from differential growth. WebTropistic responses are distinguished from nastic responses by being directional relative to the stimulus. Tropisms can be classified as “positive” or “negative” according to the … two babies found in bathtub

WebJan 1, 2024 · Tropistic responses of roots mediated by gravity and light have been extensively investigated, and a complex mutual interaction occurs between these two tropisms. To date, most studies have been conducted in 1 g , microgravity, or simulated microgravity, whereas no studies investigated root phototropism in hypergravity. WebJan 1, 2013 · Seedlings of Arabidopsis thaliana wild type (WT) and phyB mutant were exposed to unidirectional light (red or blue) or reoriented to induce a tropistic response, and small-molecule metabolites were assayed and quantified.
