Aortic root diameter, main pulmonary artery diameter/aortic root diameter and pericardial fat volume as predictors of occlusive coronary artery disease

open access: yesMonaldi Archives for Chest Disease, 2023
The clinical relevance of aortic root diameter (ARD) and main pulmonary artery diameter (MPAd) or pericardial fat volume (PFV) in the assessment of coronary artery disease (CAD) is largely unknown.

Pitfalls in Root Trait Calculations: How Ignoring Diameter Heterogeneity Can Lead to Overestimation of Functional Traits

open access: yesFrontiers in Plant Science, 2017
Specific root length (SRL) and root tissue density (RTD) are ecologically functional traits which are calculated from root length or volume and root dry weight. Both can be converted into each other using the root diameter assuming roots are cylindrical.

Influence of Root Diameter and Soil Depth on the Xylem Anatomy of Fine- to Medium-Sized Roots of Mature Beech Trees in the Top- and Subsoil

open access: yesFrontiers in Plant Science, 2017
Despite their importance for water uptake and transport, the xylem anatomical and hydraulic properties of tree roots have only rarely been studied in the field.

Fine-Root Decomposition and Nutrient Return in Moso Bamboo (Phyllostachys pubescens J.Houz.) Plantations in Southeast China

open access: yesFrontiers in Plant Science, 2022
Plant fine-root decomposition is an important pathway for the reentry of nutrients into the soil. Studies have mainly focused on the loss of fine-root mass and the release characteristics of major elements, including, C, N, and P, but there are few ...

Global transcriptomic analysis reveals candidate genes associated with different phosphorus acquisition strategies among soybean varieties

open access: yesFrontiers in Plant Science, 2022
IntroductionSoybean adapts to phosphorus-deficient soils through three important phosphorus acquisition strategies, namely altered root conformation, exudation of carboxylic acids, and symbiosis with clumping mycorrhizal fungi.

Fine root contribution to the soil carbon stock of an agroforestry system in a Caatinga-Atlantic Forest transition zone

open access: yesRevista Brasileira de Ciências Ambientais, 2021
The objective of this work was to evaluate the distribution of fine roots and its influence on the soil organic carbon stock, at a depth of 20 cm, in a Grevillea robusta and Coffea arabica agroforestry system.

The Response of Plants and Mycorrhizal Fungi to Nutritionally-Heterogeneous Environments Are Regulated by Nutrient Types and Plant Functional Groups

open access: yesFrontiers in Plant Science, 2021
Nutrient type and plant functional group are both important in influencing proliferation of roots or hyphae and their benefit to plant growth in nutritionally heterogeneous environments.

Trade-Offs in Phosphorus Acquisition Strategies of Five Common Tree Species in a Tropical Forest of Puerto Rico

open access: yesFrontiers in Forests and Global Change, 2021
Tree species that are successful in tropical lowlands have different acquisition strategies to overcome soil phosphorus (P) limitations. Some of these strategies belowground include adjustments in fine-root traits, such as morphology, architecture ...

Deep rooting development and growth in upland rice NERICA induced by subsurface irrigation

open access: yesPlant Production Science, 2020
Changes in root development and growth in upland rice receiving subsurface irrigation were evaluated using root box experiments. Irrigated water was independently applied every day to depths of 0, 5, 10 and 20 cm from the ground surface, and root ...

Investigation of Root Morphological Traits Using 2D-Imaging among Diverse Soybeans (Glycine max L.)

open access: yesPlants, 2021
Roots are the most important plant organ for absorbing essential elements, such as water and nutrients for living. To develop new climate-resilient soybean cultivars, it is essential to know the variation in root morphological traits (RMT) among diverse ...
