Miller & Levine Biology 2018-01-01T00:00:00Z When these “fire followers” sense the chemicals emitted from burned materials, they release a hormone called auxin that sparks germination. Plants Have Hormones, Too, and Tweaking Them Could Improve Food Supply 2020-07-30T04:00:00Z Smetana et al. show that the cue that determines organizer function is provided by the local accumulation of auxin, which promotes the expression of HD-ZIP III transcription factors. Plant-thickening mechanisms revealed 2019-01-08T05:00:00Z But because dicamba, like 2,4-D, mimics plant hormones called auxins, it is also toxic to a wide variety of broadleaf and woody plants.

Biology for AP Courses 2022-06-09T00:00:00Z Changes in auxin concentration are responsible for this action, which can occur within a matter of hours in seedlings. Miller & Levine Biology 2018-01-01T00:00:00Z Yet because all known plants contain auxin, as well as the smoke-sensing proteins, it remains unclear why most of them do not actually respond. Plants Have Hormones, Too, and Tweaking Them Could Improve Food Supply 2020-07-30T04:00:00Z The Dot settles into its spot, where you’ll connect a built-in auxin connector and an included and very short USB cable for power. iHome makes a spot for your Echo Dot in its retooled clock radio 2017-08-18T04:00:00Z For years, Harmer had been looking for a link between those genes and the release of a hormone called auxin, which controls stem growth. Watch a sunflower dance in the sun: Now scientists know how it’s done 2016-08-05T04:00:00Z Many effects on plant development are under the influence of cytokinins, either in conjunction with auxin or another hormone. Biology for AP Courses 2022-06-09T00:00:00Z They absorb less light as days shorten, auxin production drops, and ethylene production increases, shutting down the leaf. Miller & Levine Biology 2018-01-01T00:00:00Z Plant genes are known to regulate the level of a hormone called auxin, which causes stems and shoots of plants to lengthen. Here's How Flowers Move—and Why 2016-08-04T04:00:00Z According to the manufacturer’s literature, the chemical is believed to work by mimicking growth hormones called auxins, causing plant cells to crazily multiply. Cellular Cheaters Give Rise to Cancer 2015-07-27T04:00:00Z Abolishing PIN polarization, such as by inhibiting endocytosis, interferes with local auxin responses in the embryo, leading to transformation of embryonic leaves to the root-like structures. Retraction: Generation of cell polarity in plants links endocytosis, auxin distribution and cell fate decisions : Nature : Nature Publishing Group 2014-07-15T04:00:00Z While many synthetic auxins are used as herbicides, IAA is the only naturally occurring auxin that shows physiological activity. Biology for AP Courses 2022-06-09T00:00:00Z The plant hormone auxin regulates a variety of developmental processes and responses to environmental inputs, often via changes in gene transcription. [Report] Cell Surface ABP1-TMK Auxin-Sensing Complex Activates ROP GTPase Signaling 2014-02-27T19:26:47.729Z The investigators, however, found that auxin does not work alone. Here's How Flowers Move—and Why 2016-08-04T04:00:00Z A plant hormone called auxin, which spurs the growth of leaves, flowers, and other plant organs, is the key: Florets grow where auxin flows. ScienceShot: Sunflowers Do the Math 2013-06-14T19:05:00Z Our Letter reported that PIN transporters for the plant hormone auxin are initially delivered to the plasma membrane in a non-polar manner and that their polar distribution requires endocytosis. Retraction: Generation of cell polarity in plants links endocytosis, auxin distribution and cell fate decisions : Nature : Nature Publishing Group 2014-07-15T04:00:00Z Applying synthetic auxins to tomato plants in greenhouses promotes normal fruit development. Biology for AP Courses 2022-06-09T00:00:00Z Instead, ABP1 functions at the cell surface to bind auxin and a family of membrane kinases, thereby activating intracellular guanosine triphosphatases to initiate important developmental changes in cell shape. [Report] Cell Surface ABP1-TMK Auxin-Sensing Complex Activates ROP GTPase Signaling 2014-02-27T19:26:47.729Z Christopher Schoene, now at the University of Oxford, UK, and his team engineered Escherichia coli so that the bacterium would migrate into plant roots and produce the growth hormone auxin. Synthetic biologists and conservationists open talks 2013-04-17T17:20:28.297Z Fruits such as seedless cucumbers can be induced to set fruit by treating unfertilized plant flowers with auxins. Biology for AP Courses 2022-06-09T00:00:00Z For example, apical dominance seems to result from a balance between auxins that inhibit lateral buds, and cytokinins that promote bushier growth. Biology for AP Courses 2022-06-09T00:00:00Z Outdoor application of auxin promotes synchronization of fruit setting and dropping to coordinate the harvesting season. Biology for AP Courses 2022-06-09T00:00:00Z Its activity counters many of the growth-promoting effects of GAs and auxins. Biology for AP Courses 2022-06-09T00:00:00Z Strigolactones promote seed germination in some species and inhibit lateral apical development in the absence of auxins. Biology for AP Courses 2022-06-09T00:00:00Z Signals between these compounds and other hormones, notably auxin and GAs, amplifies their physiological effect.
