To reduce competition with food crops, third-generation bioenergy crops are expected to colonize low quality lands where they need to withstand stresses including low nutrient supply and seasonal flooding. Therefore, it is a critical time to exploit the beneficial traits of plant-microbe interactions to compensate the potential biomass loss and increase crop performance when growing on marginal land, through plant breeding programs or microbial consortia inoculation practices. To successfully harness plant microbiome, we need to first identify the most consistent microbial helpers associated with different perennial grass candidates and the potential functions that the microbes perform. For example, plant microbiomes have exhibited the capacity of biological nitrogen fixation and nitrification suppression, helping increase nitrogen supply for plant hosts. In this study, five bioenergy feedstocks of perennial C4 grasses grown on seasonally flooding soil were investigated. DNA was extracted from root-zone soil samples of five different feedstock from 2020 and 2021 for microbiome analysis. We also measure the potentials of N cycling functions including nitrogen fixation and nitrification activities. We found that perennial energy crop candidates harbored distinct microbial communities from adjacent systems. The microbial genera enriched in the C4 perennial grass root zones, such as BD1-7 clade, Haliangium, MND1 and Paenibacillus, have been previously reported to enhance plant resistance of biotic and abiotic stresses and promote nutrient uptake. Moreover, the switchgrass cultivar Shawnee exhibited higher N sustainability by displaying significant higher biological nitrogen fixation potentials.
