Bacterial microbiome associated with Common bean, Phaseolus vulgaris L., grown in Pacific Northwest in 2023

In this study, we evaluated 16 common bean cultivars spanning 77 years of breeding history to investigate how genotype, soil N availability, and environmental conditions affect plant growth, N fixation, and the composition of root-associated bacterial communities. Field trials were conducted over two consecutive growing seasons under differing soil fertility conditions, particularly N availability.

本研究以16个涵盖77年育种历程的普通菜豆品种为研究材料，探究基因型、土壤氮素有效性及环境条件对植株生长、固氮作用以及根际细菌群落组成的影响。本研究在差异化土壤肥力条件（尤以氮素有效性为重点）下，于连续两个生长季开展了田间试验。
