In nature roots grow in the dark and away from light (negative phototropism). However, most current research root biology has been carried out with system grown presence of light. Here, we have engineered a device, called Dark-Root (D-Root), to plants vitro aerial part exposed normal light/dark photoperiod while are or specific wavelengths intensities. D-Root provides an efficient for cultivating large number seedlings easily characterizing architecture dark. At morphological level,...
Summary Phosphate (Pi) is an essential nutrient for all organisms. Roots are underground organs, but the majority of root biology studies have been done on systems growing in presence light. Root illumination alters Pi starvation response ( PSR ) at different intensities. Thus, we analyzed morphological, transcriptional and physiological responses to dark‐grown roots. We identified new genes pathways regulated by that were not described previously. also show Pi‐starved plants increase...
Previous studies have indicated that the main fractions of humic substances (HS), gray acid (GHA), brown (BHA), and fulvic (FA), present different molecular patterns in water solution are probably associated with specific structural features. However, techniques used these previous did not permit clarification principal qualitative characteristics structures. To study more depth this subject several GHA, BHA, FA been analyzed through complementary use UV−visible FTIR spectroscopy, 13C NMR,...
Abstract The aim of this review is to describe the main physicochemical characteristics diverse types humic‐metal‐phosphate acid complexes. effects these complexes on phosphorus (P) fixation in soils with different pH values and features plant uptake are also discussed. Humic‐metal‐phosphate have apparent stability constants same range as those metal‐humic complexes, solutions ionic‐strength values. Likewise, molecular‐size distribution a function similar that potassium or sodium humates...
The physiological and metabolic mechanisms behind the humic acid-mediated plant growth enhancement are discussed in detail. Experiments using cucumber (Cucumis sativus) plants show that shoot caused by a structurally well-characterized acid with sedimentary origin is functionally associated significant increases abscisic (ABA) root concentration hydraulic conductivity. Complementary experiments involving blocking agent of cell wall pores water transport (polyethylenglycol) conductivity...
The release of phytosiderephores (PS) to the rhizosphere is main root response iron (Fe) deficiency in graminaceous plants. We have investigated role Fe status shoot as well signaling pathways controlled by three relevant phytoregulators - indolacetic acid (IAA), ethylene and nitric oxide (NO) regulation this Fe-starved wheat To end, PS accumulation nutrient solution expression genes encoding nicotianamine aminotransferase (TaNAAT) ferritin (TaFER) been evaluated plants subjected different...
The chemical and structural nature of humic substances (HS) is the object an intense debate in literature involving two main theoretical positions: classical view defending macromolecular pattern, new, more recent, proposing a supramolecular pattern. In this study, we observe that both molecular patterns are present different whole systems solution. We also identify these with specific fraction HS. Thus, HS family formed by gray acids studied presented clear whereas fulvic coexistence...
A new type of superphosphate (organic complexed (CSP)) has been developed by the introduction organic chelating agents, preferably a humic acid (HA), into chemical reaction single (SSP) production. This modification yielded product containing monocalcium phosphate agent through Ca bridges. Theoretically, presence these monocalcium-phosphate-humic complexes (MPHC) inhibits fixation in soil, thus increasing P fertilizer efficiency. study investigateed structural and functional features CSP...
Although the ability of humic (HA) and fulvic acids (FA) to improve plant growth has been demonstrated, knowledge about mechanisms responsible for direct effects HA FA on promotion is scarce fragmentary. Our study investigated causal role both root PM H+-ATPase activity ABA in SHA-promoting action shoot growth. The involvement these processes regulation cytokinin concentration was also studied. aim integrate such responses providing new insights current model mode promoting Experiments...
Summary Root development and its response to environmental changes is crucial for whole plant adaptation. These responses include in transcript levels. Here, we show that the alternative polyadenylation (APA) of mRNA important root responses. Mutations FIP1 , a component machinery, affects development, cell division elongation, different abiotic stresses. Salt treatment increases amount poly(A) site usage within coding region 5′ untranslated regions (5′‐UTRs), lack activity reduces these...
Nitrogen (N) is probably the most important macronutrient and its scarcity limits plant growth, development fitness. N starvation response has been largely studied by transcriptomic analyses, but little known about role of alternative polyadenylation (APA) in such response. In this work, we show that modifies poly(A) usage a large number transcripts, some them mediated FIP1, component machinery. Interestingly, mRNAs isoforms with tags located protein-coding regions or 5′-UTRs significantly...
ABSTRACT The water‐insoluble phases of phosphate fertilisers have traditionally been considered an agronomic concern because their phosphorus bioavailability. However, this chemical behaviour with respect to its solubility in soil could be advantage from the point view environmental sustainability, since these phosphates are more stable and less susceptible blockage by adsorption. Hence, plants a long‐term bioavailable form for nutrition, which may increase performance crop. phosphate‐based...
