摘要

基因组数据科学(包括生物信息学)的民主化可以使科学、技术、工程和数学人才队伍多样化,进而为空间科学带来新的视角。在这方面,制定教育和研究计划,将基因组科学与 "地方 "和特定地区的世界观联系起来,对土著学生和教育工作者来说非常有价值。通过多机构合作,我们开发了一个持续的教育计划和模式,其中包括 Illumina 和 Oxford Nanopore 测序、免费生物信息平台和教师培训讲习班,通过基于地方的科学教育视角来实现我们的研究和教育目标。高中生和研究人员培养、测序、组装和注释了 13 种细菌的基因组,这些细菌来自具有文化相关性的火星模拟地点,其中 10 种是新物种。学生、教师和社区成员协助发现了与天体生物学相关的新的、潜在的化石营养细菌。这项联合教育研究计划还导致从火星模拟地点发现了能够产生 N-酰基均丝氨酸内酯的物种,这种内酯是用于细菌交流的法定人数感应分子。全基因组测序在高中教室完成,将学生与资助的空间研究联系起来,提高了研究成果,并提供了与文化相关的、以地方为基础的科学教育,参与者命名了本文所述的三种新物种。圣安德鲁学校(夏威夷檀香山)的学生为新物种的模式菌株 BL16AT(DSM 112479T = NCTC 14602T)命名为 Bradyrhizobium prioritasuperba。非营利组织 Kauluakalana 建议将新物种的模式菌株 K61T 命名为 Brenneria ulupoensis(DSM 116657T = LMG = 33184T),夏威夷浸礼会学院的学生建议将新物种的模式菌株 BL16ET 命名为 Paraflavitalea speifideiaquila(DSM 112478T = NCTC 14603T)。

Bridging Place-Based Astrobiology Education with Genomics, Including Descriptions of Three Novel Bacterial Species Isolated from Mars Analog Sites of Cultural Relevance.

Democratizing genomic data science, including bioinformatics, can diversify the STEM workforce and may, in turn, bring new perspectives into the space sciences. In this respect, the development of education and research programs that bridge genome science with "place" and world-views specific to a given region are valuable for Indigenous students and educators. Through a multi-institutional collaboration, we developed an ongoing education program and model that includes Illumina and Oxford Nanopore sequencing, free bioinformatic platforms, and teacher training workshops to address our research and education goals through a place-based science education lens. High school students and researchers cultivated, sequenced, assembled, and annotated the genomes of 13 bacteria from Mars analog sites with cultural relevance, 10 of which were novel species. Students, teachers, and community members assisted with the discovery of new, potentially chemolithotrophic bacteria relevant to astrobiology. This joint education-research program also led to the discovery of species from Mars analog sites capable of producing N-acyl homoserine lactones, which are quorum-sensing molecules used in bacterial communication. Whole genome sequencing was completed in high school classrooms, and connected students to funded space research, increased research output, and provided culturally relevant, place-based science education, with participants naming three novel species described here. Students at St. Andrew's School (Honolulu, Hawai'i) proposed the name Bradyrhizobium prioritasuperba for the type strain, BL16AT, of the new species (DSM 112479T = NCTC 14602T). The nonprofit organization Kauluakalana proposed the name Brenneria ulupoensis for the type strain, K61T, of the new species (DSM 116657T = LMG = 33184T), and Hawai'i Baptist Academy students proposed the name Paraflavitalea speifideiaquila for the type strain, BL16ET, of the new species (DSM 112478T = NCTC 14603T).
