Calcium and Calmodulin Involve in Mycorrhizal and Root Development in Trifoliate Orange Colonized by Rhizophagus intraradices

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
A pot experiment was made to study effects of ethylene glycol tetraacetic acid (EGTA, an inhibitor of Ca2+) and trifluoperazine (TFP, an inhibitor of calmodulin (CaM) on mycorrhizal colonization, growth performance, and chlorophyll, sucrose and glucose ...

Rice root genetic architecture: Meta-analysis from a drought QTL database [PDF]

open access: yes, 2009
During the last 10 years, a large number of quantitative trait loci (QTLs) controlling rice root morphological parameters have been detected in several mapping populations by teams interested in improving drought resistance in rice.

Disruption of mycorrhizal extraradical mycelium and changes in leaf water status and soil aggregate stability in rootbox-grown trifoliate orange

open access: yesFrontiers in Microbiology, 2015
Arbuscular mycorrhizas possess well developed extraradical mycelium (ERM) network that enlarge the surrounding soil for better acquisition of water and nutrients, besides soil aggregation. Distinction in ERM functioning was studied under a rootbox system,

A starting guide to root ecology: strengthening ecological concepts and standardising root classification, sampling, processing and trait measurements

open access: yesNew Phytologist, 2020
Summary In the context of a recent massive increase in research on plant root functions and their impact on the environment, root ecologists currently face many important challenges to keep on generating cutting‐edge, meaningful and integrated knowledge.

Rhizosphere microbiome mediates systemic root metabolite exudation by root-to-root signaling

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Root exudation of metabolites is an important mediator of plant interactions with soil microbes. Here we demonstrate that the tomato rhizosphere microbiome affects the chemical composition of root exudation through a systemic root–root ...

"GALVANOTROPISM" OF ROOTS [PDF]

open access: yesJournal of General Physiology, 1927
1. New experiments, made in such a way to eliminate as completely as possible products of polarization and the migration of such products when formed, have shown that the exhibition of galvanotropic curvature in roots is mainly dependent upon such products, since no curvature appears when they are excluded. 2.

Functional Conservation and Divergence of Soybean GmSTOP1 Members in Proton and Aluminum Tolerance

open access: yesFrontiers in Plant Science, 2018
Proton (H+) and aluminum (Al) rhizotoxicity are two major factors limiting crop production in acid soils. Orthologs of the zinc-finger transcription factor, Sensitive To Proton Rhizotoxicity1 (STOP1), have been found to play an essential role in the ...
