Major lineages of land plants
Web17 feb. 2014 · Relationships among these lineages and the closest relatives of land plants have varied in previous studies depending on taxon sampling and gene choice. Some studies agree with our results placing Zygnematophyceae as sister to land plants [ 25 , 27 , 80 – 82 ], while other phylogenetic analyses indicate that Charophyceae [ 23 , 83 , 84 ] or … WebTherefore, changes in soil chemical properties and physical structures caused by plant type differences (land use differences) drive the composition of the saprophytic fungi community. The differences in SOM make it possible for soil saprophytic fungal communities to have more ecological niches to utilize the more abundant SOM and redistribute it to plants in …
