FIG 2.

Heat map summarizing the relative abundances of the 35 most dominant genera in DNA samples directly extracted from epiphytic and endophytic bacteria found on hypogeous organs (roots), epigeous organs (leaves and spikes), and processed wheat (grain, chaff, bran, and flour) of the Odisseo (O) and Saragolla (S) varieties. Hypogeous and epigeous organs were analyzed at the tillering, stem elongation, booting, flowering, milk development, and physiological maturity stages. Commercial grain, bran, and flour were also analyzed as a control. The color key defines the percentages of OTUs in the samples.
