Abstract Lignin is a complex polymer deposited in the cell wall of specialised plant cells, where it provides essential cellular functions. Plants coordinate timing, location, abundance and composition lignin deposition response to endogenous exogenous cues. In roots, fine band lignin, Casparian strip encircles endodermal cells. This forms an extracellular barrier solutes water plays critical role maintaining nutrient homeostasis. A signalling pathway senses integrity this diffusion can...
Abstract The endodermis is a key cell layer in plant roots that contributes to the controlled uptake of water and mineral nutrients into plants. In order provide such functionality endodermal wall has specific chemical modifications consisting lignin bands (Casparian strips) encircle each cell, deposition waxy-like substance (suberin) between plasma membrane. These two extracellular deposits control diffusion enabling direct movement solutes out vascular system roots. Loss integrity...
It is known that the presence of arbuscular mycorrhizal fungi within plant roots enhances tolerance host to different environmental stresses, although positive effect in plants under waterlogged conditions has not been well studied. Tolerance flooding can be achieved through molecular, physiological and anatomical adaptations, which will affect their water uptake capacity therefore root hydraulic properties. Here, we investigated properties non-flooded flooded non-mycorrhizal tomato...
Abstract The adaptation capacity of olive trees to different environments is well recognized. However, the presence microorganisms in soil also a key factor response these drought. objective present study was elucidate effects arbuscular mycorrhizal (AM) fungi coming from diverse soils on plant growth and water relations. Olive plants were inoculated with native AM fungal populations two contrasting environments, that is, semi‐arid – Freila (FL) humid Grazalema (GZ) regions, subjected...
Summary The formation of Casparian strips (CS) and the deposition suberin at endodermis plant roots are thought to limit apoplastic transport water ions. We investigated specific role each these barriers in control hydro‐mineral by consequences on shoot growth. A collection Arabidopsis thaliana mutants defective and/or CS development was characterized under standard conditions using a hydroponic system Phenopsis platform. Mutants altered had enhanced root hydraulic conductivity, indicating...
Global climate changes have serious consequences on natural ecosystems and cause diverse environmental abiotic stressors that negatively affect plant growth development. Trees are dependent their symbiosis with mycorrhizal fungi, as the hyphal network significantly improves uptake of water essential mineral nutrients by colonized roots. A number recent studies has enhanced our knowledge functions associations between fungi Moreover, a series timely investigated impact benefit root symbioses...
Abstract Background Flooding reduces supply of oxygen to the roots affecting plant water uptake. Some flooding-tolerant tree species including tamarack ( Larix laricina (Du Roi) K. Koch) produce adventitious in response flooding. These were reported have higher hydraulic conductivity under flooding conditions compared with non-adventitious roots. In present study, we examined structural and functional modifications seedlings explain their tolerance. Results Seedlings subjected treatment for...
Plants respond to salinity by altering their physiological parameters in order maintain water balance. The reduction root hydraulic conductivity is one of the first responses plants presence salt minimize stress. Although its regulation has been commonly attributed aquaporins activity, osmotic adjustment and toxic effect Na+ Cl− have also a main role whole process. We studied effects 30 mM NaCl on Phaseolus vulgaris after 9 days found different over-time. An initial final conductivity,...
The relatively better performance of mycorrhizal plants subjected to drought stress has commonly been linked improved root water uptake through the fungal regulation plant aquaporins and hormones. In this study, we examined role ectomycorrhizal fungi in relations hormonal balance under mild using split-root seedlings Populus trichocarpa × deltoides either with or without inoculation Laccaria bicolor. compartments where treatment was applied had higher ABA lower cytokinin tZR contents,...
Abstract A key impediment to studying water-related mechanisms in plants is the inability non-invasively image water fluxes cells at high temporal and spatial resolution. Here, we report that Raman microspectroscopy, complemented by hydrodynamic modelling, can achieve this goal - monitoring hydrodynamics within living root tissues cell- sub-second-scale resolutions. imaging of water-transporting xylem vessels Arabidopsis thaliana mutant roots reveals faster transport endodermal diffusion...
ABSTRACT Effects of ectomycorrhizal (ECM) fungus Suillus tomentosus on water transport properties were studied in jack pine ( Pinus banksiana ) seedlings. The hydraulic conductivity root cortical cells L pc and the whole system pr ECM plants was higher by twofold to fourfold compared with non‐ECM HgCl 2 had a greater inhibitory effect seedlings, suggesting that mercury‐sensitive, aquaporin (AQP)‐mediated largely responsible for differences between two groups plants. rapidly drastically...
Abstract: Black spruce (Picea mariana), white glauca), and jack pine (Pinus banksiana) seedlings were inoculated with Hebeloma crustuliniforme or Laccaria bicolor subjected to NaCl Na 2 SO 4 treatments. The effects of ectomycorrhizas on salt uptake, growth, gas exchange, needle necrosis varied depending the tree fungal species. In seedlings, ectomycorrhizal (ECM) fungi reduced shoot root dry weights in ECM spruce, there was a small increase weights. Sodium chloride treatment net...
Jasmonic acid (JA) and arbuscular mycorrhizal (AM) symbioses are known to protect plants against abiotic biotic stresses, but also involved in the regulation of root hydraulic conductance (L). The objective this experiment was elucidate role JA water relations hormonal AM under drought by using tomato defective synthesis (def-1). Our results showed that is uptake transport through its effect on both physiological parameters (stomatal L) molecular parameters, mainly controlling expression...
Complex interactions between mycorrhizal helper bacteria (MHBs) and fungi have rarely been studied in the context of drought. Separately, both MHB inoculation moderate drought stress previously shown to enhance desert truffle mycorrhization Helianthemum almeriense plants, but combined effect them has not evaluated yet. The goal this study is determine whether Terfezia claveryi can be triggered by applying Pseudomonas mandelii #29 under could improve plant water-relations. To investigate...
