a Log CFU of EB in 1 gram dry weight (DW) of rice seeds across seven culture media; NA- nutrient agar, SCDA- soybean casein dextrose agar, as general purpose media, R2A- reasoner’s 2 agar for oligotrophs, PKA- pikovskaya’s agar for phosphate solubilizers, JA- jensen’s agar for nitrogen fixers, R2A/CMC- reasoner’s 2 agar/ carboxymethyl cellulose for cellulolytic bacteria, R2A/PEC- reasoner’s 2 agar/citrus pectin for pectinolytic bacteria. The error bar represents log ± S.E. distribution of EB across b the three agroecosystems and c six different rice genotypes. Stacked bars represent the diversity of EB species in mature rice seeds and the height of individual color bar shows the relative frequency of a species
