Difference in hydroxamic acid content in roots and root exudates of wheat (Triticum aestivum L.) and rye (Secale cereale L.): Possible role in allelopathy
(Kluwer Academic Publishers-Plenum Publishers, 1991)
Hydroxamic acids (Hx) produced by some cereal crops have been associated with allelopathy. However, the release of Hx to the soil by the producing plant-an essential condition for a compound to be involved in allelopathy-has ...
The effect of root exudates on root architecture in Arabidopsis thaliana
Root architecture is of key importance for plant nutrition and performance. It is known that root architecture is determined by genetics and environmental conditions. The aim of the present study was to evaluate if root ...
Effects of allelochemicals from tobacco root exudates on seed germination and seedling growth of tobacco
(Allelopathy Journal, 2014-01)
The composition of root exudates from two varieties (K 326 and NC 89) of tobacco were identified by GC-MS. Organic acids,amides and esters were the main constituents of the root exudates which differed in their qualitative ...
Not all ALMT1-type transporters mediate aluminum-activated organic acid responses: the case of ZmALMT1 - an anion-selective transporter
(Blackwell PublishingOxfordInglaterra, 2008)
Auxin effects on Pb phytoextraction from polluted soils by Tegetes minuta L. and Bidens pilosa L.: Extractive power of their root exudates
(Elsevier Science, 2016-07)
The principal impediment for Pb uptake by plants is the Casparian strip in roots. It prevents metals reaching the xylem, thereby hampering translocation to the aerial organs. In the root apices, young root cells have thin ...
Two effects of combined nitrogen on the adhesion of Rhizobium etli to bean roots
Combined forms of nitrogen negatively influence rhizobia-legume symbiosis. The effects of combined nitrogen are known for nodulation and dinitrogen (N2) fixation, but little is known about the effect on preinfection events. ...
Transcriptional profiling of aluminum toxicity and tolerance responses in maize roots
Maize plants (Zea mays) root exudates enhance lindane removal by native Streptomyces strains
The organochlorine pesticide (OP) lindane was removed from minimal medium (MM) by two Streptomyces native strains, while growing on maize root exudates (REs) as a primary carbon and energy source. REs supported 55 and 35% ...
Cr(VI) and lindane removal by Streptomyces M7 is improved by maize root exudates
(Wiley VCH Verlag, 2017-12)
Environmental mixed pollution by both organic and inorganic compounds are detected worldwide. Phytoremediation techniques have been proposed as ecofriendly methods for cleaning up polluted sites. Several studies have ...
Epichloë exudates promote in vitro and in vivo arbuscular mycorrhizal fungi development and plant growth
Background and aims: We studied, through exudates employment, the effect of Epichloë (endophytic fungi), both independently and in association with Bromus auleticus (grass), on arbuscular mycorrhizal fungi (AMF) colonization, ...
