Variation of the linkage of root function with root branch order. [PDF]

open access: yesPLoS ONE, 2013
Mounting evidence has shown strong linkage of root function with root branch order. However, it is not known whether this linkage is consistent in different species.

Methodology-Dependent Reversals in Root Decomposition: Divergent Regulation by Forest Gap and Root Order in <i>Pinus massoniana</i>. [PDF]

open access: yesPlants (Basel)
Understanding root decomposition dynamics is essential to address declining carbon sequestration and nutrient imbalances in monoculture plantations. This study elucidates how forest gaps regulate Pinus massoniana root decomposition through comparative ...

Square-root higher-order Weyl semimetals

open access: yesNature Communications, 2022
The topological properties of square-root Weyl semimetals are derived from the square of the Hamiltonian. Here, the authors propose a tight-binding model for a square-root higher-order Weyl semimetal hosting both Fermi-arc surface and hinge states.

The root condition for the third order polynomials

open access: yesMathematical Modelling and Analysis, 1999
This paper deals with a root condition for polynomial of the second and third order. We prove the root criterion for such polynomial with complex coefficients and find regions for the root condition in the special coefficients’ phase space.

Do ectomycorrhizal and arbuscular mycorrhizal temperate tree species systematically differ in root order-related fine root morphology and biomass? [PDF]

open access: yesFront Plant Sci, 2015
While most temperate broad-leaved tree species form ectomycorrhizal (EM) symbioses, a few species have arbuscular mycorrhizas (AM). It is not known whether EM and AM tree species differ systematically with respect to fine root morphology, fine root ...

Extending the Root-Locus Method to Fractional-Order Systems [PDF]

open access: yesJournal of Applied Mathematics, 2008
The well-known root-locus method is developed for special subset of linear time-invariant systems known as fractional-order systems. Transfer functions of these systems are rational functions with polynomials of rational powers of the Laplace variable s.

Soil environmental changes drive root decomposition under acid and nitrogen deposition in Chinese fir plantation, China. [PDF]

open access: yesBMC Plant Biol
The decomposition of underground roots is a crucial component of soil carbon turnover and nutrient input processes. However, our understanding of how root chemistry and soil environments interact during root decomposition remains limited, and differences

Trade-offs in survival strategies: root trait differentiation of trees and shrubs on the Jingpo Lake lava platform. [PDF]

open access: yesOpen Life Sci
To investigate the adaptive strategies of root functional traits in woody plants of different life forms on the Jingpo Lake lava platform towards heterogeneous habitats and provide reference for vegetation restoration strategies on lava platforms, this ...

Response strategies of fine root morphology of Cupressus funebris to the different soil environment

open access: yesFrontiers in Plant Science, 2022
Understanding fine root morphology is crucial to uncover water and nutrient acquisition and transposition of fine roots. However, there is still a lack of knowledge regarding how the soil environment affects the fine root morphology of various root ...
