项目摘要

Since Protists are overlooked in paddy field soil and mostly neglected in soil microbiology studies, I wrote two review articles focusing on protists to highlight their importance in the paddy field soil ecosystem. The first review article was written to highlight the research needs and discuss potential research ideas on biochar–protist interaction, which would advance our knowledge of biochar–microbe interaction. This article was published in the top journal of the Soil Science category, Biochar. This 2nd review highlights the essential roles of protists in a wetland rice field soil and the need for further research to fill the gaps in knowledge regarding the diversity and functions of the protists in this unique agroecosystem. In another study, we focused on the effects of protists on active bacterial communities in paddy field soils, which was recently published in one of the top journals of Soil Science, Biology and Fertility of Soils. Since one of the aims of this project is to understand protist-endophytic bacteria interaction, we made research aiming to investigate the effects of soil as a microbial source on the assemblage of the endophytic bacterial communities in rice roots, which was recently published in Biology and Fertility of Soils. Although not yet published, we have finished 2 more studies. One study focused on the effect of nitrogen-based fertilizers on protist communities, which was awarded "Excellent Poster Presentation Award" by the scientific committee of the KAAB International Symposium 2023.

由于原生生物在稻田土壤中被忽视，并且在土壤微生物学研究中大多被忽视，因此我写了两篇针对原生生物的综述文章，以强调它们在稻田土壤生态系统中的重要性。第一篇评论文章的目的是强调研究需求并讨论生物炭-原生生物相互作用的潜在研究思路，这将增进我们对生物炭-微生物相互作用的了解。这篇文章发表在土壤科学类顶级期刊Biochar上。第二次综述强调了原生生物在湿地稻田土壤中的重要作用，以及需要进一步研究以填补有关原生生物在这个独特的农业生态系统中的多样性和功能的知识空白。在另一项研究中，我们重点研究了原生生物对稻田土壤中活性细菌群落的影响，该研究最近发表在土壤科学、生物学和土壤肥力顶级期刊之一上。由于该项目的目的之一是了解原生生物与内生细菌的相互作用，我们进行了旨在调查土壤作为微生物来源对水稻根部内生细菌群落组合的影响的研究，该研究最近发表在 Biology 和土壤肥力。虽然尚未发表，但我们已经完成了另外 2 项研究。一项研究重点关注氮基肥料对原生生物群落的影响，该研究被 2023 年 KAAB 国际研讨会科学委员会授予“优秀海报展示奖”。
