A molecular method to identify species of fine roots and to predict the proportion of a species in mixed samples in subtropical forests

open access: yesFrontiers in Plant Science, 2015
Understanding of belowground interactions among tree species and the fine root (≤2 mm in diameter) contribution of a species to forest ecosystem production are mostly restricted by experimental difficulties in the quantification of the species ...

A Molecular Identification Protocol for Roots of Boreal Forest Tree Species

open access: yesApplications in Plant Sciences, 2014
Premise of the study: Roots play a key role in many ecological processes, yet our ability to identify species from bulk root samples is limited. Molecular tools may be used to identify species from root samples, but they have not yet been developed for ...
