<abstract xmlns="http://www.w3.org/1999/xhtml">To complete the wide range of studies on chemical composition and pharmacological potential of the fruit of <italic>Ribes nigrum</italic> and <italic>Ribes rubrum</italic>, this work aimed to perform a comparative morpho-anatomical characterization of the fruits of both species and complete previously records of black currant as frequently studied species. Microslides of fruits were made with rotation microtome, and then cross sections were stained with toluidine blue. Documentation and evaluation were carried out in microphotos. In <italic>R. rubrum</italic>, the epidermis cells are ovoid to round, while those of <italic>R. nigrum</italic> are rectangular to almost round. Under the epidermis, in both fruits, there are two layers of oval hypodermal cells. Underneath the hypodermal layers, parenchyma cells of different size with thin walls and scattered collateral closed bundles were detected. The seeds are embedded in a gelatinous sheath having large thin-walled cells. Endocarp separates the arillar tissue from parenchyma cells, in addition, a gap can be found among these layers, endocarp, arillar tissue, and seeds. The seed coat consists of sclerenchyma cells in both species. In conclusion, histological differences and similarities were described in the fruits of the selected <italic>Ribes</italic> species, highlighted the first morpho-anatomical description of the berry of <italic>Ribes rubrum</italic>.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">This paper presents the obtained results on the chorology and conservation status of the lycopod species identified in Mureș County. It also represents a basis for further studies on monitoring, and establishes conservation measures for these species that are of community interest, included in the IUCN category LC (least concern). During the study, five lycopod species out of the seven listed in Romania were identified. The species are wide spread, occurring in groups that extend over relatively large areas. The conservation status is predominantly good and very good.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"><italic>Leucojum vernum</italic> L. (Amaryllidaceae) is a bulbous geophyte from Central Europe known as medicinal and ornamental plant. Native population of this species can be found in the Peres Forest (parcels number 23-24) from Velyka Dobron Wildlife Reserve (Western Ukraine), monitored continuously since 2014. The aim of this study was the morphometric evaluation of the species and the chemistry analysis of the soil in which the species grow. According to our results the length of leaf sheath was the most variable parameter from the evaluated morphometric indicators (number of leaves, maximum leaf length and width, bract length, leaf sheath length, scape length, and bulb diameter). Correlations were found between maximum leaf length and scape length, but also between maximum leaf length and bract length. Soil chemistry analysis showed that the chemical properties of the soil are favorable for the studied plants. The soil pH was slightly acidic, the humus content and the supply of alkaline hydrolyzed nitrogen were high, and the amount of soluble P2O5 was moderate. Differences between the territories were found with respect to the soil agrochemical parameters.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">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.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Phytosociological structure of the communities dominated by <italic>Scirpus sylvaticus</italic> was studied in the mountain area of Mureş County with focus on vegetation community organization, floristic composition and habitat conservation. The vegetation sampling and data analysis were done following standard procedures. The study of wet meadows from the Călimani and Gurghiului Mountains carried out in field during 2015-2019, highlights the presence of hygrophilous coenoses belonging to the <italic>Scirpetum sylvatici</italic> Ralski 1931 plant association. These wet meadows grow on alluvial, gleyic and acidophilous soils. The identified communities belong to Natura 2000 habitat 6430 Hydrophilous tall-herb fringe communities of plains in the montane to alpine levels. The conservation status of the habitat is good and very good and the floristic composition emphasizes a rich floristic diversity.</abstract>
