细菌类群的生态学作用对于了解微生物群落如何应对不断变化的环境条件仍然至关重要。在这里，我们分析属Curtobacterium，因为它被发现是最丰富的分类在落叶群落在南加州。传统的描述这个分类群主要将其作为干豆农作物中的致病病原体。因此，我们试图调查该属的丰度是否是因为它作为植物病原体的作用或其他生态作用。通过整理微杆菌科120个基因组的24，000多个16S rRNA序列，我们表明短杆菌属在全球范围内分布，主要存在于土壤生态系统中。此外，该属具有高度多样性的基因组潜力，用于降解碳水化合物，特别是结构多糖。我们的结论是，短杆菌可能是负责凋落物群落内的有机质降解。
Assigning ecological roles to bacterial taxa remains imperative to understanding how microbial communities will respond to changing environmental conditions. Here we analyze the genus Curtobacterium, as it was found to be the most abundant taxon in a leaf litter community in southern California. Traditional characterization of this taxon predominantly associates it as the causal pathogen in the agricultural crops of dry beans. Therefore, we sought to investigate whether the abundance of this genus was because of its role as a plant pathogen or another ecological role. By collating >24,000 16S rRNA sequences with 120 genomes across the Microbacteriaceae family, we show that Curtobacterium has a global distribution with a predominant presence in soil ecosystems. Moreover, this genus harbors a high diversity of genomic potential for the degradation of carbohydrates, specifically with regards to structural polysaccharides. We conclude that Curtobacterium may be responsible for the degradation of organic matter within litter communities.
