Conteúdo: |
Gluconacetobacter diazotrophicus is a species of great agronomic potential due to its growth-promotion traits. Its colonization process in different plants has been reported. However, there have been no studies regarding its structural colonization in elephant grass. This is a fast-growing C4-Poaceae plant, and its application in Brazil is mainly aimed at feeding dairy cattle, due to its high nutritional value. Also, in the last decade, this grass has been applied in the production of biofuels. The present study aimed to monitor the colonization process of strain LP343 of G. diazotrophicus inoculated in elephant grass seedlings of PCEA genotype, by using a mCherry-tagged bacterium. Samples of roots and shoots collected at different periods were visualized by confocal laser-scanning microscopy. The colony-counting assay was used to compare the number of cells recovered in different niches and a qPCR was performed for the quantification of endophytic cells in root and shoot tissues. Results suggested that the strain LP343 quickly recognized the PCEA roots as host, attached to the elephant grass roots at 6 h, and 7 days after inoculation were able to colonize the xylem vessels of roots and shoots of elephant grass. This study advances our knowledge about the colonization process of G. diazotrophicus species in elephant grass, contributing to future studies involving the plant-bacteria interaction cultivated under gnotobiotic conditions. |
