In the early stages of the development of terrestrial life, land plants were rootless and leafless. Since they had their origins in aqueousenvironments, they did not require the specialized conducting and supporting tissues afforded byrootsandstems, nor did they require localized regions ofcarbohydrate...
fungi in decaying leaf litterNutrient cycling in tropical forests is dependent on fungi such as these growing in decaying leaf litter. Fungi decompose dead organic matter, releasing nutrients back into the ecosystem to be taken up by the roots of plants. ...
A large number of roots emerged from the bottom of the cuttings growing in gravel in four of five boxes. This response may be more characteristic of S. nigra than other tree willows [12]. However, there was also a large amount of fine root in a substrate offering low resistance to root...
During the growing season, there was no significant correlation between TRW and PRE in the EH region, while in the EL region, TRW was positively correlated with PRE in July of the current year (r = 0.514, p < 0.05). In the ML region, TRW was correlated positively with PRE in May of...

Even the putative precursor of both must have been quite complex and must have evolved a mechanism to prevent loss to the environment of its tip-growing subunits exported to the end through the central hole. I suggest that tip-capping machinery first evolved in its ancestor when an even ...
Roots were excavated using an Air-Spade . Regression analysis resulted in two equations for predicting total carbon storage based on height and diameter of trees up to 20 cm dbh: Y = 0.05836 (dbh 2) for root carbon storage, and Y = 0.0305 (dbh 2 脳 h) 0.9499 for above-ground carbon ...
The tree is rooted according to (Raymann et al., 2015), but alternative roots are indicated with numbered red dots (see main text for discussion). Grey font indicates the clades for which no isolates are available. Currently proposed taxonomic status: C = Class; P = Phylum; SC = Super ...
