国际空间站（ISS）为研究微重力条件下植物的生长发育提供了宝贵的机会。本研究利用国际空间站日本KIBO实验模块，将野生型、野生型MCA1-GFP型、mca1敲除型和mca1过表达型4个品系拟南芥种子置于凝胶固化的ms培养基上，在尼龙蕾丝网上进行培养，并在微g和1 g条件下检测根系与网状网的缠结情况。结果表明，微g条件下，根与网的缠结增强，根卷曲现象明显。这种行为在mca1基因敲除的幼苗中不太明显，尽管MCA1-GFP在幼苗根尖的分布在微g生长的幼苗和地面对照的幼苗中几乎相同。讨论了MCA1参与根缠结的可能性。
The International Space Station (ISS) provides a precious opportunity to study plant growth and development under microgravity (micro-G) conditions. In this study, four lines of Arabidopsis seeds (wild type, wild-type MCA1-GFP, mca1-knockout, and MCA1-overexpressed) were cultured on a nylon lace mesh placed on Gelrite-solidified MS-medium in the Japanese experiment module KIBO on the ISS, and the entanglement of roots with the mesh was examined under micro-G and 1-G conditions. We found that root entanglement with the mesh was enhanced, and root coiling was induced under the micro-G condition. This behavior was less pronounced in mca1-knockout seedlings, although MCA1-GFP distribution at the root tip of the seedlings was nearly the same in micro-G-grown seedlings and the ground control seedlings. Possible involvement of MCA1 in the root entanglement is discussed.
