| 单词 | gibberellin |
| 例句 | Bayer’s genetic engineers have focused on a plant growth hormone called gibberellin. How shrinking corn could help farmers—and the environment 2023-10-25T04:00:00Z The lower stem nodes of these varieties make insufficient amounts of gibberellin to activate internode elongation. Genetic drivers of high-rise rice that survives deep floods 2020-07-14T04:00:00Z In these crops, gibberellin acts as a growth hormone, and the development of new crop varieties with reduced sensitivity to it allowed farmers to grow shorter and more weather-resistant stalks. Ferns communicate to decide their sexes 2014-10-22T04:00:00Z As gibberellin levels then fall, the next phase of flowering factors is released from gibberellin repression. [Report] Gibberellin Acts Positively Then Negatively to Control Onset of Flower Formation in Arabidopsis 2014-05-08T18:26:52.239Z This way, the levels of gibberellin can be lowered in the stalks, but not the flowers, stunting the plants’ growth without undermining their productivity. How shrinking corn could help farmers—and the environment 2023-10-25T04:00:00Z Decades ago researchers knocked out the genes that control early steps in gibberellin synthesis, but the result was plants that had deformed flowers and abnormal ears. How shrinking corn could help farmers—and the environment 2023-10-25T04:00:00Z Mutations in other genes involved in the synthesis or perception of gibberellin are often responsible for the highly desired short stature of other grain crops. Genetic drivers of high-rise rice that survives deep floods 2020-07-14T04:00:00Z In this case the targets were two genes that regulate the creation of gibberellin mainly in the leaves and stalk, resulting in plants that were one-third shorter. How shrinking corn could help farmers—and the environment 2023-10-25T04:00:00Z The two opposing functions of gibberellin may facilitate evolutionary and environmental modulation of plant inflorescence architecture. [Report] Gibberellin Acts Positively Then Negatively to Control Onset of Flower Formation in Arabidopsis 2014-05-08T18:26:52.239Z To speed up the process, Bayer and other companies are working on short corn made with gene editing, an approach that can alter gibberellin without adding genes from other species. How shrinking corn could help farmers—and the environment 2023-10-25T04:00:00Z They figured out how to suppress corn genes that code for enzymes known as gibberellin 20 oxidases, which put the biochemical finishing touches on the hormone in particular parts of the plant. How shrinking corn could help farmers—and the environment 2023-10-25T04:00:00Z The activation of this cell division and elongation process requires the growth hormone gibberellin. Genetic drivers of high-rise rice that survives deep floods 2020-07-14T04:00:00Z First, gibberellin levels increase and stimulate production of key flowering factors, one of which degrades gibberellin. [Report] Gibberellin Acts Positively Then Negatively to Control Onset of Flower Formation in Arabidopsis 2014-05-08T18:26:52.239Z Although gibberellin promotes termination of vegetative development, it inhibits flower formation. [Report] Gibberellin Acts Positively Then Negatively to Control Onset of Flower Formation in Arabidopsis 2014-05-08T18:26:52.239Z We show that dual opposite roles of the phytohormone gibberellin underpin this phenomenon in . [Report] Gibberellin Acts Positively Then Negatively to Control Onset of Flower Formation in Arabidopsis 2014-05-08T18:26:52.239Z |
