However, microgravity disrupts normal plant growth, partly through excessive accumulation of abscisic acid (ABA) and indole-3-acetic acid (IAA) in roots. Here, we designed a plant probiotic system based on engineered E. coli that reduces this excessive hormonal accumulation in plant roots under microgravity conditions, enabling normal plant growth despite microgravity stress. We also developed a hardware system, Floraspin, that facilitates laboratory simulation of plant growth under microgravity conditions, and verified its effectiveness in promoting Arabidopsis germination Wiki | Official Page Thu, 29 Oct 2026 22:26:06 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://video.igem.org https://video.igem.org/client/assets/images/icons/icon-1500x1500.png https://video.igem.org/videos/watch/6551d3b6-500e-408f-b578-36cb7efa7674 All rights reserved, unless otherwise specified in the terms specified at https://video.igem.org/about and potential licenses granted by each content's rightholder.
