Plasmolemma permeability is an integral indicator of the functional state of plant cells under stress. Aquaporins (AQPs), specialized transmembrane proteins that form water channels and play an important role in the adaptation of plants to adverse conditions and, in particular, to lack or excess of water, are involved in the formation of the response to drought. The main function of AQPs is to facilitate the movement of water across cell membranes and maintain aqueous cell homeostasis. Under stressful conditions, there is both an increase and decrease in the expression of individual aquaporin genes. Analysis of the data revealed differences in the expression of AQPs genes in stable and sensitive plant genotypes. It turned out that aquaporins in different stress-resistant varieties of the same species also respond differently to drought. The review provides brief information on the history of the discovery of aquaporins, the structure and function of these proteins, summarizes the latest information on the role of aquaporins in the regulation of metabolism and the response of plants to stressors, with particular emphasis on aquaporins in drought protection. The discovery and study of AQPs expands the possibilities of using genetic engineering methods for the selection of new plant species, in particular, more resistant to drought and salinization of the soil, as well as to increase their productivity. The use of aquaporins in biotechnology to improve drought resistance of various species has many prospects.

The article is a continuation of the series of publications on the genus Galerina in Ukraine. In previous publications, those species were considered that are grouped by the presence of remarkable morphological features, for example, tibiiform cystidia, pleurocystidia, or calyptrate spores. This article reports the species of the genus Galerina without any noticeable peculiarities (G. cephalotricha, G. norvegica, G. pumila, and G. triscopa), as well as few recently found in Ukraine species possessing pleurocystidia (G. karstenii) and tibiiform cystidia (G. hybrida and G. tibiicystis) recorded after the relevant articles have been published. The infrageneric position of many of the considered here species still remains indeterminate. For all reported species, their diagnoses, locality data in Ukraine, general distribution in the world, as well as original drawings of their carpophores and microstructures, are provided.

Alpine ecosystems are especially sensitive to climatic changes which affect the relationships among glaciers, snow, vegetation and soils. Our aim was to examine how the variation in the abiotic environment affected soil properties and plant species distribution at regional and local scales. We sampled soil and vegetation along two transects set on the opposite-facing slopes (North versus South), from the alpine-nival ecotone to the snowline (Central Great Caucasus, Kazbegi, Georgia). We measured also soil temperature and controlled for the slope inclination. Multivariate ordination methods were used to link abiotic factors, soil properties and plant species distribution along the gradients. We found that ordination models were better resolved when soil properties were used as environmental variables instead of abiotic ones such as elevation, inclination and slope aspect. Soil pH and plant available potassium were the best predictors of plant species distribution in these habitats. We conclude that the models that account for the role of soils as a mediator between the abiotic environment and vegetation can more accurately describe plant species distribution at local and regional scales: a potentially important amendment with implications for the monitoring of the effects of climate change on vegetation at least in high mountain systems.

The article provides information on distribution of some noteworthy representatives of the genus Galerina in Ukraine. This genus is still rather fragmentarily studied in the country, therefore it is a subject of a series of special articles. The previous two articles, on the species of Galerina with tibiiform cheilocystidia and those possessing pleurocystidia, have already been published. This article reports species with so-called calyptrate spores. In these spores, the outer layer of the spore wall (perisporium) is separated from the main wall to form blisters at the basal (sometimes also apical) part of the spore. One of the reported species, Galerina sahleri, was found for the first time in Ukraine; other three species (G. cerina, G. hypnorum, and G. sphagnicola) were recorded in new localities. All these fungi are bryotrophic, often sphagnicolous. Their diagnoses, data about finds in Ukraine and general distribution as well as original drawings of the fruit bodies and microstructures are provided.

The generalized information on the distribution of Pisolithus arhizus (Sclerodermataceae, Boletales, Basidiomycota) in Ukraine is provided. Pisolithus arhizus is listed in the Red Data Book of Ukraine as a rare species reported only from Kharkiv, Kherson, Odesa, Poltava regions and the Autonomous Republic of Crimea. This article significantly expands our knowledge on distribution patterns of P. arhizus in Ukraine. New records from Donetsk, Ivano-Frankivsk, Mykolayiv, Zaporizhzhya, and Zhytomyr regions are added to those previously reported. Despite the increased number of the reports, this fungus is nevertheless considered to be a rare species in Ukraine; therefore, it is necessary to search for its new localities.

The article outlines the details on several noteworthy records of corticoid fungi discovered in the course of mycological observations in Prypiat-Stokhid National Nature Park (Liubeshiv District, Volyn Region) in October, 2019. In Ukraine, Byssocorticium atrovirens is apparently known only from a single record of A. Pilat, 1933, from the present-day territory of Carpathian Biosphere Reserve. Piloderma bicolor has been earlier recorded only once from Skole Beskids National Nature Park, while Tomentella lilacinogrisea has been previously found in a single locality in Carpathian Biosphere Reserve. The data on detailed morphological descriptions, ecological peculiarities, substrate specialization, general distribution, photographs of basidiomata and original drawings of microstructures are provided.

Noteworthy records of 11 alien plant species in Kyiv City and Kyiv Region made mainly in 2020 are discussed. In particular, new localities of the following taxa are reported: Amaranthus spinosus, Artemisia tournefortiana, Chenopodium ucrainicum, Celastrus orbiculatus, Datura innoxia, Dysphania ambrosioides, Erechtites hieraciifolius, Mesembryanthemum ×vascosilvae (M. cordifolium × M. haeckelianum; recently described as Aptenia ×vascosilvae and reported here for the first time for Ukraine; earlier this ornamental hybrid was misidentified as Aptenia cordifolia), Parietaria officinalis, Phytolacca americana, Thladiantha dubia. The presence in Ukraine of several additional species, such as Datura wrightii and Phytolacca acinosa s.l. (incl. P. esculenta), that may occur as escaped near places of their cultivation, is reported; these species may be confused with D. innoxia and P. americana, respectively. The growing role of alien plants escaped from cultivation (ergasiophytes) in the present-day processes of formation of the alien flora of Ukraine is emphasized.

Trifolium vesiculosum is listed in the current floristic inventories as a species native to Ukraine. In order to clarify the native versus alien status of this taxon, we studied historical and recent literature and herbarium data.We also report here our new record of the species. We found T. vesiculosum in 2020 in Mykolayiv Region (Mykolayiv District, Andriivka village, on the alluvial terrace of the Southern Bug River valley), in a disturbed habitat with predominantly synanthropic and alien species. Previous finds of T. vesiculosum in Ukraine were reported mainly in publications of the 19th century and were based on a few herbarium specimens from the present-day territory of Odesa Region. Due to characteristics of these records, dates and localities of the finds of T. vesiculosum in Ukraine, we have traced its probable introductions during the 19th century in the port of Odesa, on the sand deposits of the Danube River, in the German settlements, and therefore we can confirm the conclusion of Paczoski (1921) who assumed the alien status of the species in Ukraine. Thus, T. vesiculosum is classified as a kenophyte (introduced before 1808). Taking into account the current climatic changes in Ukraine, we emphasize the need for further monitoring of the species, changes in its dispersal strategy, and for registration of its introduction and dispersal pathways.

In the course of the present study, surveys on occurrence and distribution of ectomycorrhizal (EcM) fungi in tropical sal forests of foothills of the Himalayas, India, were undertaken. The species of two genera of agarics, namely Asproinocybe and Inocybe, were found organically associated with the roots of Shorea robusta (sal tree). However, prior to our study the genus Asproinocybe has not been reported from India. In this article, the morpho-anatomical details of mycorrhizal roots of Shorea robusta associated with Asproinocybe lactifera and Inocybe purpureoflavida are provided for the first time. The EcM colonized roots of the two species are distinguished by differences in the shape and colour of the roots, surface texture, size and shape of cystidia, type of mantle, as well as different chemical reactions. Asproinocybe lactifera EcM is mainly characterised by a monopodial pinnate mycorrhizal system with the dark brown to reddish brown and loose cottony surface, while in Inocybe purpureoflavida it is irregularly pinnate to coralloid, silvery grey to reddish brown, with densely woolly surface. The outer mantle layer is heterogeneous with obclavate to awl-shaped cystidia in Asproinocybe lactifera, whereas Inocybe purpureoflavida EcM have a plectenchymatous outer mantle with subcylindrical to obclavate metuloidal and non-metuloidal cystidia. The presence of lactifers in the mantle is a unique feature in Asproinocybe lactifera as compared to Inocybe purpureoflavida.

Asproinocybe lactifera EcM is mainly characterised by a monopodial pinnate mycorrhizal system with the dark brown to reddish brown and loose cottony surface, while in Inocybe purpureoflavida it is irregularly pinnate to coralloid, silvery grey to reddish brown, with densely woolly surface. The outer mantle layer is heterogeneous with obclavate to awl-shaped cystidia in Asproinocybe lactifera, whereas Inocybe purpureoflavida EcM have a plectenchymatous outer mantle with subcylindrical to obclavate metuloidal and non-metuloidal cystidia. The presence of lactifers in the mantle is a unique feature in Asproinocybe lactifera as compared to Inocybe purpureoflavida.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48205277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
