Evidences of adaptive traits to rocky substrates undermine paradigm of habitat preference of the Mediterranean seagrass Posidonia oceanica [PDF]

open access: yes, 2015
Posidonia oceanica meadows are acknowledged as one of the most valuable ecosystems of the Mediterranean Sea. P. oceanica has been historically described as a species typically growing on mobile substrates whose development requires precursor communities.

In situ Root Phenotypes of Cotton Seedlings Under Phosphorus Stress Revealed Through RhizoPot

open access: yesFrontiers in Plant Science, 2021
Phosphorus (P) deficiency is a common challenge in crop production because of its poor mobility through the soil. The root system plays a significant role in P absorption from the soil and is the initial indicator of low P levels. However, the phenotypic

High resolution synchrotron imaging of wheat root hairs growing in soil and image based modelling of phosphate uptake

open access: yes, 2013
Root hairs are known to be highly important for uptake of sparingly soluble nutrients, particularly in nutrient deficient soils. Development of increasingly sophisticated mathematical models has allowed uptake characteristics to be quantified.

The effect of root hairs on root water uptake is determined by root–soil contact and root hair shrinkage

open access: yesNew Phytologist, 2023
Summary The effect of root hairs on water uptake remains controversial. In particular, the key root hair and soil parameters that determine their importance have been elusive. We grew maize plants (Zea mays) in microcosms and scanned them using synchrotron‐based X‐ray computed microtomography.

Filling the Gaps to Solve the Extensin Puzzle [PDF]

open access: yes, 2018
Extensins (EXTs) are highly repetitive plant O-glycoproteins that require several post-translational modifications (PTMs) to become functional in plant cell walls.

Morphological responses of root hairs to changes in soil and climate depend on plant life form

open access: yesFrontiers in Forests and Global Change
IntroductionRoot hairs increase the surface area of a plant’s root system that is in contact with the soil, thus facilitating plant water and nutrient uptake.

Nod Factors Alter the Microtubule Cytoskeleton in Medicago truncatula Root Hairs to Allow Root Hair Reorientation

open access: yesMolecular Plant-Microbe Interactions, 2005
The microtubule (MT) cytoskeleton is an important part of the tip-growth machinery in legume root hairs. Here we report the effect of Nod factor (NF) on MTs in root hairs of Medicago truncatula.

A New Species of \u3ci\u3eAphis\u3c/i\u3e in Minnesota (Hemiptera: Aphididae) on Narrow-Leaved Purple Coneflower, \u3ci\u3eEchinacea Angustifolia\u3c/i\u3e [PDF]

open access: yes, 2018
Aphis echinaceae, n. sp. is described from specimens collected in Douglas County, Minnesota, on Echinacea angustifolia (DC.). The aphid is illustrated with biometric data for alate and apterous vivipara.

A Model for the Development of the Rhizobial and Arbuscular Mycorrhizal Symbioses in Legumes and Its Use to Understand the Roles of Ethylene in the Establishment of these two Symbioses [PDF]

open access: yes, 2002
We propose a model depicting the development of nodulation and arbuscular mycorrhizae. Both processes are dissected into many steps, using Pisum sativum L. nodulation mutants as a guideline. For nodulation, we distinguish two main developmental programs,

Hair testing is taking root [PDF]

open access: yesAnnals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2011
An increasing number of toxicology laboratories are choosing to expand the services they offer to include hair testing in response to customer demands. Hair provides the toxicologist with many advantages over conventional matrices in that it is easy to collect, is a robust and stable matrix that does not require refrigeration, and most importantly ...
