TLDR
This Viewpoint addresses the need for a centralized fine-root trait database, and introduces the Fine-Root Ecology Database (FRED), which so far includes > 70 000 observations encompassing a broad range of root traits and also includes associated environmental data.Abstract:
Variation and tradeoffs within and among plant traits are increasingly being harnessed by empiricists and modelers to understand and predict ecosystem processes under changing environmental conditions. While fine roots play an important role in ecosystem functioning, fine-root traits are underrepresented in global trait databases. This has hindered efforts to analyze fine-root trait variation and link it with plant function and environmental conditions at a global scale. This Viewpoint addresses the need for a centralized fine-root trait database, and introduces the Fine-Root Ecology Database (FRED, http://roots.ornl.gov) which so far includes > 70 000 observations encompassing a broad range of root traits and also includes associated environmental data. FRED represents a critical step toward improving our understanding of below-ground plant ecology. For example, FRED facilitates the quantification of variation in fine-root traits across root orders, species, biomes, and environmental gradients while also providing a platform for assessments of covariation among root, leaf, and wood traits, the role of fine roots in ecosystem functioning, and the representation of fine roots in terrestrial biosphere models. Continued input of observations into FRED to fill gaps in trait coverage will improve our understanding of changes in fine-root traits across space and time.read more

TL;DR: Wang et al. as discussed by the authors designed a soil column experiment with a 3 m transparent glass tube depth, and the soil moisture was controlled to be 50% (W1, water shortage), 70% (w2, suitable), and 90% (WC, surplus) of the maximum field capacity, respectively, and cut off the deep root system under 50 cm at the jointing stage of wheat.

Decoupling of tree height and root depth across the globe and the implications for tree mortality during drought events
TL;DR: In this paper , the authors investigated the relationship between tree height and root depth across different climate conditions and the implications for tree mortality during drought events and found that the linkage of below-and above-ground reaches has a pivotal role in understanding tree mortality.

Grounding trait‐based root functional ecology
TL;DR: The root functional ecology has experienced the same problems and, for several reasons, its foundations seem even more unstable as mentioned in this paper , and it is difficult to precisely define components of the root system that have homogenous functions.

Let the concept of trait be functional

TL;DR: An unambiguous definition of plant trait is given, with a particular emphasis on functional trait, and it is argued that this can be achieved by developing "integration functions" which can be grouped into functional response (community level) and effect (ecosystem level) algorithms.
