mongolicum shrubs ( P < 0.01), and Rhodospirillales showed a trend of enrichment towards roots under C . microphylla shrubs ( P < 0.01) and H . scoparium shrubs ( P < 0.02).
Specifically, Rhizobiales was the dominant bacterial order with the highest relative abundance under the three leguminous plant shrubs, presenting a significant trend of enrichment towards roots in all of the four rhizocompartments under leguminous plant shrubs ( P <0.01); Xanthomonadales also presented a significant trend of enrichment towards roots under leguminous plant shrubs ( P < 0.05).
