It has long been recognized that the community of organisms associated with plant roots is a critical component of the phytobiome and can directly or indirectly contribute to the overall health of the plant. The rhizosphere microbial community is influenced by a number of factors including the soil type, the species of plants growing in those soils, and in the case of cultivated plants, the management practices associated with crop production. species, such as highbush blueberry and American cranberry, are woody perennials that grow in sandy, acidic soils with low to moderate levels of organic matter and a paucity of nutrients. When properly maintained, fields planted with these crops remain productive for many years. In some cases, however, yields and fruit quality decline over time, and it is suspected that degenerating soil health and/or changes in the rhizosphere microbiome are contributing factors. Determining the assemblage of bacterial and fungal microorganisms typically associated with the rhizosphere of these crops is a critical first step toward addressing the complex issue of soil health. We hypothesized that since blueberry and cranberry are in the same genus and grow in similar soils, that their associated rhizosphere microbial communities would be similar to each other. We analyzed the eukaryotic (primarily fungal) and bacterial communities from the rhizosphere of representative blueberry and cranberry plants growing in commercial fields in New Jersey. The data presented herein show that while the bacterial communities between the crops is very similar, the fungal communities associated with each crop are quite different. These results provide a framework for examining microbial components that might contribute to the health of spp. crops in New Jersey and other parts of the northeastern U.S.
长期以来，人们一直认识到与植物根系相关的生物群落是植物微生物组的关键组成部分，能够直接或间接地促进植物的整体健康。根际微生物群落受到多种因素的影响，包括土壤类型、生长在这些土壤中的植物种类，以及对于栽培植物而言，与作物生产相关的管理措施。高丛蓝莓和美国蔓越莓等植物是木本多年生植物，生长在沙质、酸性土壤中，有机质含量低至中等，养分匮乏。如果管理得当，种植这些作物的田地可以多年保持高产。然而，在某些情况下，产量和果实品质会随着时间下降，人们怀疑土壤健康状况恶化和/或根际微生物组的变化是促成因素。确定与这些作物根际通常相关的细菌和真菌微生物组合是解决土壤健康这一复杂问题的关键第一步。我们假设，由于蓝莓和蔓越莓属于同一属且生长在相似的土壤中，它们相关的根际微生物群落会彼此相似。我们分析了新泽西州商业田地中代表性蓝莓和蔓越莓植物根际的真核生物（主要是真菌）和细菌群落。本文呈现的数据表明，虽然两种作物之间的细菌群落非常相似，但与每种作物相关的真菌群落却大不相同。这些结果为研究可能有助于新泽西州和美国东北部其他地区 spp. 作物健康的微生物成分提供了一个框架。
