“…transport is highly dynamic and reversible. Further studies on the synchronization of fungal and plant aquaporins need to be conducted in the context of abiotic stresses, as well as under stimulation of stress-related and mycorrhiza-related phytohormones (Zargar et al, 2017;Lanfranco et al, 2018;Calvo-Polanco et al, 2019).…”

“…Physiological roles of aquaporins with known transport capacities can be inferred by the alteration and synchronization of their expressions in response to abiotic stresses and stress-related phytohormones such as abscisic acid, cytokinins, salicylic acid, and strigolactones (Zargar et al, 2017;Lanfranco et al, 2018;Calvo-Polanco et al, 2019). The functional importance of aquaporins is also implied by the differential expressions of fungal aquaporins in extraradical mycelium, mantle and Hartig net, and of plant aquaporins in epidermis, cortex and endodermis ( Figure 1A).…”

Ectomycorrhizal fungi influence root water transport of host plants. To delineate the exact mechanisms of how fungal partner alters root water relations, it is important to understand the functions of fungal transmembrane water channels, i.e., aquaporins, the key component in the symplastic pathways. In this paper, we discussed what roles the fungal aquaporins may play in root water transport. We also highlighted the opportunities of using integrated approaches to address rising questions in future hotspots of aquaporin and root water relations research.

“…Considering the extensive damage caused by WD in plants and the future prospects of increases in the frequency and intensity of drought events, several studies have explored the mechanisms underlying plant tolerance to water restriction (Jiang et al , Wani et al , Xie et al , Zargar et al ). To date, these mechanisms have been found to commonly include a reduction in g s , the control of damage caused by oxidative stress and molecular and structural adaptations of the photosynthetic apparatus.…”

A variety of cellular responses is needed to ensure the plants survival during drought, but little is known about the signaling mechanisms involved in this process. Soybean cultivars (EMBRAPA 48 and BR 16, tolerant and sensitive to drought, respectively) were exposed to the following treatments: control conditions (plants in field capacity), drought (20% of available water in the soil), sodium nitroprusside (SNP) treatment (plants irrigated and treated with 100‐µM SNP [SNP–nitric oxide (NO) donor molecule], and Drought + SNP (plants subjected to drought and SNP treatment). Plants remained in these conditions until the reproductive stage and were evaluated for physiological (photosynthetic pigments, chlorophyll a fluorescence and gas exchange rates), hydraulic (water potential, osmotic potential and leaf hydraulic conductivity) and morpho‐anatomical traits (biomass, venation density and stomatal characterization). Exposure to water deficit considerably reduced water potential in both cultivars and resulted in decrease in photosynthesis and biomass accumulation. The addition of the NO donor attenuated these damaging effects of water deficit and increased the tolerance index of both cultivars. The results showed that NO was able to reduce plant's water loss, while maintaining their biomass production through alteration in stomatal characteristics, hydraulic conductivity and the biomass distribution pattern. These hydraulic and morpho‐anatomical alterations allowed the plants to obtain, transport and lose less water to the atmosphere, even in water deficit conditions.

This mini-review briefly presents the main types of plant aquaporins, highlighting their importance for different plant species and for plant cellular functions. Aquaporins (AQPs), families of water channel proteins (WCPs) are transmembrane proteins that are present in prokaryotes, animals, plants, and humans. The plant aquaporins are part of the Major Intrinsic Proteins (MIPs) family which resides in the following plant organs: roots, stems, leaves, flowers, fruits, and seeds. According to the sub-cellular localization, to their sequence homologies and to their phylogenetic distribution, plant aquaporins have been divided in five subgroups: (a) plasma membrane intrinsic proteins (PIPs); (b) tonoplast intrinsic proteins (TIPs); (c) Nodulin26-like intrinsic membrane proteins (NIPs); (d) small basic intrinsic proteins (SIPs) and (e) uncharacterized intrinsic proteins (XIPs). Different subclasses of the plant aquaporins allow several types of transport using: water, glycerol, urea, hydrogen peroxide, organic acids, ethanol, methanol, arsenite, lactic acid, and gaseous compounds. Plant aquaporins have a significant role in cell response to cold stress, photosynthesis, plant growth, cell elongation, reproduction, and seed germination.
