Impatiens edgeworthii is an important plant species endemic to Western Himalaya. In this species male reproductive organs conceal the stigma – seat of pollen reception during male phase therefore acts as barrier for self-pollination. In addition the stigma become receptive only after the androecium of the same flower is shed and then receptive stigma become exposed. This unique type of dichogamy and arrangement of essential organs are contrivance for cross-pollination in the species. The large showy flowers, production of large quantities of nectar, protandry, presence of nectar guides, ornamented exine sculpturing, high pollen to ovule ratio points towards cross-pollinated mode of reproduction is operative in this species. This was also established by breeding experiments. Our study may prove useful in conservation of this Himalayan endemic plant species and also useful in understanding the evolution of breeding system in the genus.
凤仙花(Impatiens edgeworthii)是西喜马拉雅特有的重要植物种。在这个物种中,雄性生殖器官隐藏了雄蕊期花粉接收的柱头座,因此对自花授粉起了屏障作用。此外,柱头只有在同一朵花的雄蕊脱落后才会发生受感,然后受感柱头才会暴露。这种独特的二分法和重要器官的排列是该物种异花授粉的设计。大而艳丽的花朵,生产大量的花蜜,原雄蕊,花蜜向导的存在,装饰的外壁雕刻,高花粉与胚珠的比例表明异花授粉的繁殖模式在这个物种中是有效的。育种实验也证实了这一点。本研究对该喜马拉雅特有植物的保护具有重要意义,对了解该属植物繁殖系统的演化也具有重要意义。

The locations of nine species of jelly cyanolichens of the families Coccocarpiaceae, Heppiaceae, Koerberiaceae, Lichinaceae, Massalongiaceae found in the Magadan Region are reported. Spilonema paradoxum Bornet is recorded for the first time in Asia; five species, Ephebe perspinulosa Nyl., Heppia lutosa (Ach.) Nyl., Koerberia biformis A. Massal., Peccania coralloides (A. Massal.) A. Massal., and Thallinocarpon nigritellum (Letau) P.M. Jørg., are new for the Russian Far East; Polychidium muscicola (Sw.) Gray is first found in the Magadan Region, and the two species, Euopsis granatina (Sommerf.) Nyl. and Spilonema revertens Nyl., are rare lichens in this region. The geographical distribution patterns and ecology of these species are discussed. Findings in the north of the Russian Far East of such lichens as Heppia lutosa, Koerberia biformis, Peccania coralloides, and Thallinocarpon nigritellum are the most interesting and unexpected in the phytogeographical respect. All of them are relic elements in the flora of the Magadan Region.

Quantitative dynamics of the early Pliocene climate and vegetation in the Lena River Delta (northern Yakutia, Eastern Siberia) 东西伯利亚雅库特北部勒拿河三角洲早上新世气候与植被的定量动态
Q3 Environmental Science Pub Date : 2022-01-01 DOI: 10.17581/bp.2022.11212

Early Pliocene climate and vegetation evolution in the Lena River Delta (northern Yakutia, Eastern Siberia) are quantitatively studied for the first time in de­ tail, based on a palaeobotanical record. Palaeobotanical data for this time-interval were obtained on 28 palynofloras from the Sardakhskaya Formation in the coastal cliffs of the Sardakh-Sisse Island (Lena River Delta). In this first integrative study we apply the Coexistence Approach (CA) for quantification of palaeoclimate, the Plant Functional Types (PFT) approach and Integrated Plant Record (IPR) vegetation analysis for quantification of palaeovegetation. Our investigation documents the persistence of temperate climate with two warmer and colder phases. Moreover, our reconstructions show significantly higher mean values of all temperature parameters in comparison to previous estimations. Overall hu­ mid climate conditions (up to 1500 mm) prevailed throughout the early Pliocene correspond to an oceanic climate. Our reconstruction indicates relatively strong temperature and precipitation seasonality. Our data for vegetation show more open vegetation in comparison to previous studies reconstructing mixed conifer- deciduous forests for the early Pliocene of Northeast of Russia. Based on PFT, the early Pliocene vegetation of northern Yakutia in Lena River Delta mainly was presented by more or less open mixed deciduous woodlands of warmer or colder temperate type. The results obtained from the PFT approach generally are in ac­ cordance with our data obtained from IPR approach. However, based on IPR, periodically forests and grasslands were obtained in addition to open woodlands.
根据古植物学记录,首次对勒拿河三角洲(东西伯利亚雅库特北部)早上新世的气候和植被演化进行了定量研究。在这段时间内,对勒拿河三角洲Sardakh-Sisse岛海岸悬崖上的Sardakhskaya组的28个孢粉植物进行了古植物学研究。本文采用共存法(共存法)对古气候进行定量分析,采用植物功能类型法(PFT)对古植被进行定量分析,采用综合植物记录法(IPR)进行古植被定量分析。我们的调查记录了温带气候的持续存在,有两个温暖和寒冷的阶段。此外,我们的重建显示,所有温度参数的平均值明显高于以前的估计。整个上新世早期的气候条件为中胡气候(1500毫米以下),属于海洋性气候。我们的重建结果表明,温度和降水的季节性相对较强。我们的植被数据显示,与先前重建俄罗斯东北部上新世早期针叶林-落叶混交林的研究相比,植被更加开阔。基于PFT,勒拿河三角洲北部雅库特地区早上新世植被主要表现为偏暖或偏冷温带的开放型混合落叶林地。用PFT方法得到的结果与我们用IPR方法得到的数据基本一致。然而,在知识产权的基础上,除了开阔的林地外,还获得了周期性的森林和草原。

We present data on the diversity of culturable fungi associated with brown algae Sargassum miyabei (the Sea of Japan, Russia). By the plate method, 269 isolates were obtained using solid nutrient media and 31 species from 12 genera were identified based on phenotypic as well as molecular genetic traits (using ITS and beta-tubulin markers) in cases where identification based on morphological features alone was difficult. The structure of the species composition was analyzed and the list of species was given. The analysis showed that facultative marine fungi were the vast majority of the species diversity, namely Penicillium, Cladosporium, Alternaria, Monodictys, Sarocladium, Trichoderma, Fusarium, Arthrinium, Botrytis and Aspergillus species. Among obligate marine fungi, Paradendryphiella and Piricauda species were revealed by the method mentioned above. Also, taxonomic affiliation and phylogenetic position of some Penicillium representatives have been clarified.
我们提出了与褐藻马尾藻相关的可培养真菌多样性的数据(日本海,俄罗斯)。采用平板法,在固体营养培养基上分离得到269株菌株,在仅凭形态特征难以鉴定的情况下,根据表型和分子遗传性状(利用ITS和β -微管蛋白标记)鉴定了12属31种菌株。对其物种组成结构进行了分析,并给出了物种列表。分析表明,兼性海洋真菌占物种多样性的绝大多数,即青霉菌、枝孢菌、Alternaria、Monodictys、Sarocladium、Trichoderma、Fusarium、Arthrinium、Botrytis和Aspergillus。在专性海洋真菌中,用上述方法发现了parendryphiella和Piricauda两种。此外,一些青霉菌代表的分类归属和系统发育地位也得到了澄清。

The artificial colorants act as a potent cytotoxic agent at the consumer level, whose analysis is inevitable. The investigation is mainly focused to analyze the toxicity of two commonly used synthetic food colorants (Brilliant blue and Fast green) with the help of Allium cepa root tip assay. The frequency of aberrations and the concentrations of both the colorants were found to be positively correlated in the chromosome studies. The integrity of the cell membranes, which is a potent parameter to detect cellular damage was detected using Evan’s blue staining. 2,3,5-triphenyl tetrazolium chloride (TTC) method was also adopted to determine the damaging effects of the synthetic molecules on the mitochondrial oxidative properties in the root tip cells. Both food colorants showed prominent membrane damage and mitochondrial activity reduction in the test material.
人工着色剂在消费者层面上是一种强效的细胞毒性物质,其分析是不可避免的。本文主要采用葱根尖法对两种常用的人工合成食品着色剂亮蓝和坚绿的毒性进行了分析。在染色体研究中发现,畸变的频率和两种着色剂的浓度呈正相关。细胞膜的完整性是检测细胞损伤的有效参数,用埃文蓝染色检测。采用2,3,5-三苯基氯化四氮唑(TTC)法测定合成分子对根尖细胞线粒体氧化特性的破坏作用。两种食用色素在测试材料中均表现出明显的膜损伤和线粒体活性降低。

With this paper we continue a new annual series, the main purpose of which is to make significant floristic findings from Russia and neighboring countries more visible in Russia and abroad. In total, this paper presents new records for 48 vascular plant species from 6 Eurasian countries, obtained during field explorations, as well as during taxonomic revisions of herbarium materials. For the first time, a new locality of Leontopodium leiolepis is recorded for Russia, Rheum uzengukuushi for China, Rorippa prolifera for Lithuania, Lappula marginata for Kyrgyzstan and Tajikistan, Anthriscus caucalis, Chenopodium ficifolium, Euphorbia prostrata for Uzbekistan, Adonis × hybrida, Potamogeton × franconicus, Solidago × niederederi for the Asian part of Russia, Echinochloa esculenta, Poa jamalinensis, Puccinellia poecilantha for Siberia, Potentilla intermedia for the Caucasus, Rhynchospora alba for the Russian part of Altai, Poa sphondylodes, Veronica beccabunga for Eastern Siberia, Asclepias syriaca for the Republic of Altai, Chimaphila umbellata, Orobanche korshinskyi, Veronica scutellata for the Republic of Buryatia, Cirsium alatum, Thalictrum simplex for the Republic of Crimea, Thymus rariflorus, Th. terekensis for the Republic of Ingushetia, Berberis thunbergii, Crataegus maximowiczii, Prunus serotina for the Republic of Mordovia, Oenothera villosa for the Republic of Tatarstan, Astragalus sulcatus, Galium mollugo for the Republic of Tyva, Phragmites altissimus for the Chelyabinsk Region, Senecio dubitabilis for the Magadan Region, Asclepias syriaca, Galatella villosa, Potentilla recta for the Novosibirsk Region, Dodartia orientalis for the Omsk Region, Viola hultenii for the Sakhalin Region, Phragmites tzvelevii for the Samara Region and the Middle Volga, Jacobaea ferganensis for the Samara Region, Carex media, Impatiens parviflora for the Tyumen Region. There are some more findings which are not new for the region but they contribute significantly to the understanding of species distribution.
