Background and Aims Regulation of water channel aquaporins (AQPs) provides another mechanism by which abscisic acid (ABA) may influence flow through plants. To the best our knowledge, no studies have addressed changes in ABA levels, abundance AQPs root cell hydraulic conductivity (LpCell) same tissues. Thus, we followed mechanisms affects hydraulics an ABA-deficient barley mutant Az34 its parental line 'Steptoe'. We compared cells to determine spatial correlations between AQP local...
To address the involvement of abscisic acid (ABA) in regulating transpiration and root hydraulic conductivity (LpRoot) their relative importance for maintaining leaf hydration, ABA-deficient barley mutant Az34 its parental wild-type (WT) genotype (cv. Steptoe) were grown hydroponics exposed to changes atmospheric vapour pressure deficit (VPD) imposed by air warming. WT plants capable water potential (ψL) that was likely due increased LpRoot enabling higher flow from roots, which response The...
Although salinity inhibits plant growth, application of appropriate rhizosphere bacteria can diminish this negative effect. We studied one possible mechanism that may underlie beneficial response. Wheat plants were inoculated with Bacillus subtilis IB-22 and Pseudomonas mandelii IB-Ki14 their consequences for water relations, concentrations the hormone abscisic acid (ABA) followed in presence soil salinity. Salinity alone increased ABA concentration wheat leaves roots was associated...
Certain lines of wild barley (Hordeum spontaneum) are more tolerant salinity than others. The physiological basis this difference is examined in a comparative study saline-tolerant and saline-intolerant line that emphasizes plant water relations.
Pseudomonas mandelii strain IB-Ki14 has recently been shown to strengthen the apoplastic barriers of salt-stressed plants, which prevents entry toxic sodium. It was interest find out whether same effect manifests itself in absence salinity and how this affects hydraulic conductivity barley plants. Berberine staining confirmed that bacterial treatment enhanced deposition lignin suberin formation Casparian bands roots The calculation conductance by relating transpiration leaf water potential...
Increased auxin levels in root primordia are important controlling branching, while their interaction with abscisic acid (ABA) likely regulates lateral development water-deficient plants. The role of ABA accumulation regulating branching was investigated using immunolocalization to detect (indoleacetic acid, IAA) and (abscisic acid) the ABA-deficient barley mutant Az34 its parental genotype (cv. Steptoe) Osmotic stress strongly inhibited Steptoe plants, but hardly affected Az34. Root...
Lipid transfer proteins (LTPs) are known to be involved in suberin deposition the Casparian bands of pea roots, thereby reinforcing apoplast barriers. Moreover, Pseudomonas mandelii IB-Ki14 strain accelerated formation wheat plants, although involvement LTPs process was not studied. Here, we investigated effects P. on LTPs, bands, hydraulic conductance and activity aquaporins (AQPs) plants. RT PCR showed a 1.6-1.9-fold up-regulation PsLTP-coding genes an increase abundance LTP phloem roots...
Little information is available on how rhizosphere bacteria affect abscisic acid (ABA) levels in plants and whether these bacterial effects are associated with improved plant water status. In this study, we tested the hypothesis that stimulation of growth may be ability ABA to increase hydraulic conductivity roots through up-regulation aquaporin. To do this, studied effect capable producing a barley mutant deficient hormone. Measurements ABA-deficient Az34 showed its tissues exhibited...
The stomatal closure of salt-stressed plants reduces transpiration bringing about the maintenance plant tissue hydration. aim this work was to test for any involvement aquaporins (AQPs) in under salinity. changes level cells were detected with help an immunohistochemical technique using antibodies against HvPIP2;2. In parallel, leaf sections stained abscisic acid (ABA). effects salinity compared those exogenously applied ABA on HvPIP2;2 levels and hydraulic conductance barley plants....
The role of reactive oxygen species (ROS) in ABA-induced increase hydraulic conductivity was hypothesized to be dependent on an aquaporin water channel (AQP) abundance. Single ABA application or its combination with ROS manipulators (ROS scavenger ascorbic acid and NADPH oxidase inhibitor diphenyleneiodonium chloride (DPI)) were studied detached roots barley plants. We measured the osmotically driven flow rate xylem sap calculated root conductivity. In parallel, immunolocalization HvPIP2;2...
The phytoremediation of soil contaminated with petroleum depends on the association plants rhizosphere bacteria capable promoting plant growth and destroying hydrocarbonates. In present work, we studied effects “Lenoil” biological product containing Pseudomonas turukhanskensis IB 1.1, hydrocarbons Secale cereale L plants, which previously proved to be resistant weak oil pollution gray forest composition microorganisms in their rhizosphere. rye roots was studied, morphometric parameters...
Local effects on plant roots or shoots are accompanied by a change of hormones concentration providing signal transduction in plants and their adaptation to changing environmental conditions. It is known that respond drought stress increasing the abscisic acid (ABA) xylem sap which leads decrease stomatal conductance prevent water loss from transpirational pathways. Earlier, we found rapid leaf ABA accumulation barley wheat under influence shortterm salinity. However, mechanism salt induced...
On March 3, 2024, sad news spread among Russian plant physiologists: an outstanding scientist and wonderful person, Farida Minnikhanovna Shakirova, died. Friends colleagues exchanged letters in attempt to honor her memory. Members of Editorial board the journal “Ecobiotech”, created by F.M. decided write about scientific activities amazing qualities: kindness, dedication science, efficiency, talent as a researcher, willingness share experience with colleagues. We would like young who did not...
