Chillies are members of the genus L. (family Solanaceae). They are native to Central and South America and consist of approximately 35 species [1,2]. Among these, five species ( L., L., Jacq., L., and Ruiz & Pav.) have been domesticated and are mainly cultivated for consumption as vegetables and spices. Of the domesticated chillies, is commercially cultivated worldwide, while and are mainly cultivated in American, Asian, and African countries [3]. We compared the diversity of microbiota in various compartments of farm-cultivated (FC) and home-planted (HP) chilli plants (). Targeted 16S rRNA gene (V5-V6 region) was sequenced using the Illumina NovaSeq 6000 platform. Proteobacteria, Actinobacteriota, Acidobacteriota, Gemmatimonadota, Bacteroidota, and Firmicutes were present in all compartments of both the FC and HP plants. Proteobacteria (or Pseudomonadota) was the predominant phylum in all the compartments of both HP and FC plants, while Actinobacteriota (or Actinomycetota) was the second most abundant phylum. Most plant compartments (leaves, fruits and roots) exhibited a higher relative abundance of Proteobacteria compared to the soil samples. With few exceptions, the soil compartments (bulk and rhizospheric soils) displayed a higher relative abundance of the phyla Myxococcota, Acidobacteriota, Gemmatimonadota, Bacteroidota, Nitrospirota, Verrucomicrobiota, and Firmicutes than the plant compartments. Diversity indices revealed that the bacterial community in chili plants clustered based on both compartment and cultivation area.
辣椒是茄属植物（茄科）。它们原产于中美洲和南美洲，约有35个物种[1,2]。其中，五个物种（辣椒、灌木状辣椒、黄灯笼辣椒、中国辣椒和智利辣椒）已被驯化，主要作为蔬菜和香料种植以供食用。在已驯化的辣椒中，辣椒在全球范围内进行商业种植，而灌木状辣椒和黄灯笼辣椒主要在美国、亚洲和非洲国家种植[3]。我们比较了农场种植（FC）和家庭种植（HP）辣椒植株（辣椒）各个部位的微生物群多样性。使用Illumina NovaSeq 6000平台对靶向的16S rRNA基因（V5-V6区域）进行测序。变形菌门、放线菌门、酸杆菌门、芽单胞菌门、拟杆菌门和厚壁菌门存在于FC和HP植株的所有部位。变形菌门（或假单胞菌门）是HP和FC植株所有部位的主要门类，而放线菌门（或放线菌纲）是第二丰富的门类。与土壤样本相比，大多数植物部位（叶子、果实和根）的变形菌门相对丰度更高。除少数例外，土壤部位（大块土壤和根际土壤）的粘球菌门、酸杆菌门、芽单胞菌门、拟杆菌门、硝化螺旋菌门、疣微菌门和厚壁菌门的相对丰度高于植物部位。多样性指数表明，辣椒植株中的细菌群落根据部位和种植区域聚类。
