Soil Influences Colonization of Root-Associated Fungal Endophyte Communities of Maize, Wheat, and Their Progenitors

Figure 1

Multidimensional scaling diagrams generated using Sorensen ((a) and (c)) and Morisita-Horn ((b) and (d)) similarity values among fungal cultures isolated from root fragments of Zea spp. ((a) and (b)) and Triticum spp. ((c) and (d)) growing in either desert (DS) or clay (CS) soils. Dimensions one and two represent synthetic variables, generated to maximize the spread of congruency distances between pairs of dependent variable values. Maize (Zea mays subsp. mays) and teosinte (Zea mays subsp. parviglumis) plants grown in the desert soil mixture = Dmaize and Dteosinte, respectively; those grown in the Missouri clay soil as Cmaize and Cteosinte, respectively. Similarly, wheat (Triticum aestivum subsp. aestivum) and its progenitor, wild wheat (Triticum monococcum subsp. monococcum), grown in desert soil are indicated as Daestivum and Dmonococcum and those grown in clay soil mixture are labeled, Caestivum and Cmonococcum, respectively.
