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，在土壤微生物学研究中也大多被忽视，我写了两篇关于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。第一篇综述文章强调了生物炭的研究需求，并讨论了生物炭与原生生物相互作用的潜在研究思路，这将促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别的顶级期刊Biochar上。第二篇综述强调了原生生物在湿地稻田土壤中的重要作用，以及进一步研究的必要性，以填补关于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，这项研究最近发表在土壤科学、生物学和土壤肥力的顶级期刊之一上。由于本项目的目的之一是了解原生生物-内生细菌的相互作用，因此我们进行了土壤作为微生物源对水稻根部内生细菌群落组合的影响的研究，这项研究最近发表在《土壤生物学与肥力》杂志上。虽然还没有发表，但我们已经完成了另外两项研究。其中一项研究聚焦于氮基肥料对原生生物群落的影响，这项研究被Kaab国际研讨会2023年科学委员会授予“优秀海报展示奖”。
