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.

pathway is regulated through several mechanisms. Plasma membrane proteins like G protein coupled receptor ligands (GPCRs) have been identified as regulators of Hippo signaling ( 17 ). Upstream intracellular adaptor proteins such as NF2, RASSFs and KIBRA interact with MST1/2 and LATS1/2 alter their function and subsequently YAP and TAZ localization ( 18 , 19 , 20 ). Cytoskeletal remodeling is caused by mechanical changes which facilitate YAP and TAZ to emerge as important factors linking extracellular matrix signals to transcriptional outputs that regulate cell


protects cells against oxidative stress generated by ionizing radiation and/or anticancer drugs. The fullerenol molecule can be also excited with visible or ultraviolet light creating a reactive molecule that easily interacts with oxygen or biomolecules and has applications in photosensitization (Grebowski, Kazmierska & Krokosz, 2013). We demonstrated that highly hydroxylated fullerenol C60(OH)x, x>30 (up to 150 mg/L) is non-toxic to human erythrocytes, however, can adsorb to plasma membrane proteins, especially to ion-dependent ATPases decreasing their

For MDR phenotype are responsible plasma membrane proteins that belong to a large superfamily of the pro- teins called the ATP-binding cassette (ABC) trans- porters, particularly:P-glycoprotein (P-gp),multidrug- resistance associated protein 1 (MRP1) and breast cancer resistance protein (BCRP
