The dioecious plant Silene latifolia has heteromorphic sex chromosomes, and comparison of the positions of sex-linked genes indicates that at least three large inversions have occurred during the evolution of the Y chromosome. In this article, we describe the isolation of a new sex-linked gene from S. latifolia, which provides new information on the evolution of this plant's young sex chromosom...
طی کاوشهای انجام شده در استانهای قزوین و آذربایجانغربی، نمونههای جالبی از جنس Silene جمعآوری شدند. Silene capitellata از بخش Capitellatae که بیشتر در ترکیه پراکنش دارد، از کوههای منطقه الموت در استان قزوین جمعآوری شده است. همچنین S. retinervis از بخش Auriculatae که توسط غضنفر از کوه قندیل عراق معرفی شده بود، از سه رویشگاه در پیرانشهر و زیوه از استان آذربایجان غربی جمعآوری شدند. این دو ...
By studying the type specimens and field works from locus classicus, it became clear that the two species of Silene eremicana and S. goniocaula which are considered as conspecific in the Flora Iranica are distinct species. Silene commelinifolia var. isophylla is considered as a synonym of S. eremicana. The numbers of herbarium specimens (voucher) are emended and the descriptions of each species...
BACKGROUND This aim of this study is to report upon traditional knowledge and use of wild medicinal plants by the Highlanders of Lukomir, Bjelašnica, Bosnia and Herzegovina (B&H). The Highlanders are an indigenous community of approximately 60 transhumant pastoralist families who speak Bosnian (Bosanski) and inhabit a highly biodiverse region of Europe. This paper adds to the growing record of ...
گونه silene mishudaghensis از بخش auriculatae، تیره میخکیان به عنوان گونه ای جدید از شمال غرب ایران توصیف می شود. گونه جدید از گونه های نزدیک s. araratica و s. longisepala بواسطه خصوصیاتی نظیر شکل برگ های قاعده ای و ساقه ای، شکل کاسه، طول دمگل میانی و جانبی و ویژگیهای دانه قابل تشخیص است.
The stabilized silene 1,1-bis(trimethylsilyl)-2-adamantylidenesilane (4) has been generated by photolysis of a novel trisilacyclobutane derivative in various solvents and studied directly by kinetic UV spectrophotometry. Silene 4 decays with second-order kinetics in degassed hexane solution at 23 °C (k/ ) 8.6 × 10-6 cm s-1) due to head-to-head dimerization. It reacts rapidly with oxygen [k(25 °...
The need to prevent and cure emerging diseases often precludes their continuing study in situ. We present studies on the process of disease emergence by host shifts using the model system of anther-smut disease (Microbotryum violaceum) on the plant genus Silene (Caryophyllaceae). This system has little direct social impact, and it is readily amenable to experimental manipulation. Our microevolu...
