Does abscisic acid affect strigolactone biosynthesis? [PDF]

open access: yes, 2010
Strigolactones are considered a novel class of plant hormones that, in addition to their endogenous signalling function, are exuded into the rhizosphere acting as a signal to stimulate hyphal branching of arbuscular mycorrhizal (AM) fungi and germination

Organic acids in the rhizosphere and phytoavailability of sewage sludge-borne trace elements Ácidos orgânicos na rizosfera e fitodisponibilidade de elementos-traço originários de lodo de esgoto

open access: yesPesquisa Agropecuária Brasileira, 2007
The aim of this work was to quantify low molecular weight organic acids in the rhizosphere of plants grown in a sewage sludge-treated media, and to assess the correlation between the release of the acids and the concentrations of trace-elements in the ...

Role of pleural fluid-serum protein carbonyl gradient in differentiating exudative and transudative effusions

open access: yesAsian Journal of Medical Sciences, 2020
Background: Pleural effusions often cause a diagnostic dilemma. The first step in the evaluation of pleural effusions is the distinction between exudates and transudates.

Rhizosphere Microbial Communities and Heavy Metals

open access: yesMicroorganisms, 2021
The rhizosphere is a microhabitat where there is an intense chemical dialogue between plants and microorganisms. The two coexist and develop synergistic actions, which can promote plants’ functions and productivity, but also their capacity to respond to ...

Transudates and exudates [PDF]

open access: yesThorax, 2002
Joseph et al have made a valuable contribution to the evaluation of pleural effusions.1 However, we would like to sound a note of caution. Throughout all the literature, including the study by Joseph et al , one message remains the same: no single test is diagnostic for transudates or exudates.2 Thus, overreliance on such a test can be very misleading ...

Potent endogenous allelopathic compounds in Lepidium sativum seed exudate: effects on epidermal cell growth in Amaranthus caudatus seedlings [PDF]

open access: yes, 2012
Many plants exude allelochemicals – compounds that affect the growth of neighbouring plants. This study reports further studies of the reported effect of cress (Lepidium sativum) seed(ling) exudates on seedling growth in Amaranthus caudatus and Lactuca ...

Effect of Organic Fe-Ligands, Released by Emiliania huxleyi, on Fe(II) Oxidation Rate in Seawater Under Simulated Ocean Acidification Conditions: A Modeling Approach

open access: yesFrontiers in Marine Science, 2018
The potential effect of ocean acidification on the exudation of organic matter by phytoplankton and, consequently, on the iron redox chemistry is largely unknown.
