From: Rhizosphere microorganisms can influence the timing of plant flowering
Verification of microbial function from the third generation. Number of days to the onset of flowering (i.e., when 80% of the control plants had floral buds of 1 cm or larger) (a, c) and shoot fresh weight (b, d) in wild-type (Wt) and two mutants (pnsB4 and pgr5) of Arabidopsis grown in microcosms in the presence of unsterilized soil slurry (WM and PM) (a, b) or sterilized soil slurry (WM-S and PM-S) (c, d) from the third generation. WM represents plants with microbiota isolates from wild-type plants in generation 3, PM represents the plants with microbiota isolates from pgr5 plants in generation 3, WM-S represents wild-type Arabidopsis grown with sterilized soil slurry, and PM-S represents Arabidopsis pgr5 mutants grown with sterilized soil slurry. Relative abundance of genes involved in N cycling (e amoA, ammonia oxidation; f nifH, N fixation; g nirK, nitrite reductase; h nosZ, nitrous oxide reductase) in soil samples of Wt and two mutant (pnsB4 and pgr5) lines of Arabidopsis grown in microcosms with the addition of unsterilized rhizosphere soil slurries of wild-type (WM) and mutant (PM) Arabidopsis cultures. Asterisk represents a significant difference between WM and PM (p < 0.05). Values are means ± SDs (n = 9 with 20 Arabidopsis plants per sample)
