Study of plant symbiotic methylotrophic bacteria

甲醇利用菌甲基化菌广泛分布于环境中，但环境中甲醇的来源一直不清楚。近年来有报道称，植物在生长过程中通过水解细胞壁周围的果胶甲酯向环境中释放大量甲醇。甲基营养细菌利用它来获取碳或能量。此外，它还被用作植物与甲基化营养盐之间共生的中介。在这项研究中，我们试图了解植物与甲基营养细菌之间的共生关系。研究了植物与甲基营养菌之间以吡咯喹啉醌（PQQ）、CO2和金属离子（特别是钙和稀土元素）为共生体进行交换的物质。

Methanol-utilizing bacteria, methylotroph, are distributed widely into environment, however the source of methanol in environment have been unclear for a long time. It was recently reported that the plants released a large amounts of methanol into the environment by hydrolyzing pectin methyl ester in around cell wall with growing. And that is utilized by methylotrophic bacteria for carbon or energy source. Furthermore, that is utilized as a mediator for symbiosis between plants and methylotroph.In this study, we tried to understand the symbiotic relationship between plants and methylotrophic bacteria. We studied some substances as symbiotic materials such as pyrroloquinoline quinone (PQQ), CO2 and metal ions (especially calcium and rare earth elements) for exchange between plants and methylotrophic bacteria.
