: The present study includes the results of the second benthic macrophytes’ monitoring period of a survey of ecological status from the Turkish coasts. The biotic index Ecological Evaluation Index (EEI-c) was used to assess the ecological status classes (ESC) and MA-LUSI the anthropogenic pressures. Sampling was made by the quadrat (20 × 20 cm) method, and the samples were collected from 93 sites in Turkish coastal waters between 2017 and 2019. In total, 240 taxa were found in the Turkish marine waters. Forty sites were classified into High ESC, 24 sites into Good, 12 sites into Moderate, 13 sites into Poor, and 4 sites into Bad ESC. The relationship between the pressure index MA-LUSI and EEIeqr values was also tested, and a negative correlation (R 2 = 0.62) was found.

: The morphological characteristics of seeds are not affected by environmental factors and can be used to identify the Euphorbia taxa. The present study aims to determine the morphological characteristics of seeds in 27 taxa of Euphorbia using scanning electron microscopy (SEM) and light microscope (LM). Findings revealed that the seeds of Euphorbia show variation in size, color, and seed surface ornamentations among different species. The seeds vary also in shape from ovoid, ellipsoidal, globose, quadrangular, compressed, to compressed-ellipsoidal with two exceptions in E. petiolata (oblong-quadrangular truncate), E. macrocarpa (subglobose), and E. szovitsii var. kharputensis (ellipsoidal quadrangular truncate). Furthermore, it was demonstrated that caruncle color, shape, and surface are different in the studied Euphorbia spp. Special attention was also paid to lipid granules indicating their shape variation among taxa from globose, broad ellipsoidal globose to reniform, although the granules were absent in some taxa. In addition, some taxa lack any caruncle. The unweighted pair group method with arithmetic mean and principal component analysis was used to assess the morphological differentiation of the seeds among the studied taxa. According to the dendrogram and plot obtained from cluster and PCA analyses, Euphorbia taxa are divided into four clusters corroborating the previous molecular phylogenetic results.
:种子的形态特征不受环境因素的影响,可用于鉴定大戟属分类群。本研究旨在利用扫描电子显微镜(SEM)和光学显微镜(LM)测定大戟属27个分类群种子的形态特征。研究结果表明,不同物种的大戟种子在大小、颜色和种子表面装饰方面存在差异。种子的形状也各不相同,从卵球形、椭球形、球状、四边形、压扁到压扁的椭球形,只有两个例外,即小叶柄E.petiolata(长圆形四边形截形)、大果果E.macrocarpa(近球形)和狭叶E.szovitsii var.karputensis(椭球形四边形截形)。此外,研究表明,在所研究的大戟属植物中,浆果的颜色、形状和表面是不同的。还特别注意脂质颗粒,表明它们在从球形、宽椭球球形到肾形的分类群中的形状变化,尽管在一些分类群中没有颗粒。此外,一些分类群没有任何车壳。采用算术平均和主成分分析相结合的未加权配对群方法来评估所研究分类群之间种子的形态分化。根据聚类分析和主成分分析获得的树状图和图谱,大戟分类群被分为四个聚类,证实了先前的分子系统发育结果。

: Anatolia is located at the intersection of three of the world’s 36 biodiversity hotspots (the Caucasus, Irano-Anatolian, and Mediterranean Basin biodiversity hotspots) and has about 10,000 plant species, over 3000 of which are endemic. Among the many reasons for the astonishing biodiversity of Anatolia, one that stands out is the Anatolian Diagonal. Although the Anatolian Diagonal has long been recognized as a biogeographical boundary between Central and Eastern Anatolia, its exact functioning is still not well understood. Thus, in this study, our aims were 1) to assess the environmental barrier function of the Anatolian Diagonal for a plant species, Noccaea vesicaria , living on and to the east of it; 2) to evaluate climate-driven range shifts (contractions or expansions), especially through the Quaternary glacial–interglacial cycles; and 3) to contribute to the long-standing debate on the causes of the floral break between the west and east of the Anatolian Diagonal. Accordingly, we used an ecological niche modeling approach with presence records and bioclimatic data. Under the present bioclimatic conditions, areas of more suitable bioclimatic conditions were observed, especially throughout and to the east of the Anatolian Diagonal, therefore largely matching the geographical distribution of N. vesicaria . However, areas of high bioclimatic suitability were also observed to the west of the Anatolian Diagonal, especially throughout the Taurus Mountains and Pontic Mountains. Thus, bioclimatic suitability by itself cannot explain the geographical distribution of N. vesicaria or the absence of it, especially to the west of the Anatolian Diagonal. Under the past bioclimatic conditions, areas of high bioclimatic suitability contracted during warmer time periods and expanded during colder time periods, suggesting that the geographical distribution of N. vesicaria contracted and expanded during warmer and colder time periods, respectively, at least around and in the Anatolian Highlands. There may be two reasons why N. vesicaria does not occur to the west of the Anatolian Diagonal: dispersal and/or biotic interactions (e.g., competition and facilitation). Biotic interactions (likely positive plant interaction or facilitation) may have played a significant role in shaping the geographical distribution of N. vesicaria , because it seems to be highly associated with the Anatolian Highlands steppe order Festuco oreophilae-Veronicetalia orientalis Hamzaoğlu whose range does not extend to Central Anatolia.
:安纳托利亚位于世界36个生物多样性热点(高加索、伊朗-安纳托利亚和地中海盆地生物多样性热点)中的3个的交汇处,拥有约1万种植物,其中3000多种是特有的。在安纳托利亚令人惊叹的生物多样性的众多原因中,安纳托利亚对角线是一个突出的原因。虽然安纳托利亚对角线长期以来一直被认为是安纳托利亚中部和东部之间的生物地理学边界,但其确切功能仍未得到很好的理解。因此,在本研究中,我们的目标是:1)评估生活在安纳托利亚对角线上及其以东的一种植物Noccaea vesicaria的环境屏障功能;2)评估气候驱动的范围移动(收缩或扩张),特别是通过第四纪冰期-间冰期旋回;3)为长期以来关于安纳托利亚对角线西部和东部花卉断裂原因的争论做出贡献。因此,我们利用存在记录和生物气候数据的生态位建模方法。在目前的生物气候条件下,主要分布在安纳托利亚对角线及其以东的生物气候条件较为适宜的地区,与水仙的地理分布基本吻合。然而,在安纳托利亚对角线以西也观察到高生物气候适宜性的地区,特别是在整个托罗斯山脉和本蒂克山脉。因此,生物气候适宜性本身并不能解释水仙花的地理分布或不存在,特别是在安纳托利亚对角线以西。在过去的生物气候条件下,高生物气候适宜性区域在温暖时期收缩,在寒冷时期扩张,表明在温暖时期和寒冷时期,至少在安纳托利亚高原周围和在安纳托利亚高原地区,水草的地理分布分别收缩和扩张。可能有两个原因可以解释为何无毛蝽没有出现在安纳托利亚对角线以西:扩散和/或生物相互作用(例如竞争和促进)。生物相互作用(可能是积极的植物相互作用或促进作用)可能在形成褐毛蕨的地理分布中发挥了重要作用,因为它似乎与安纳托利亚高原草原目Festuco oreophilae-Veronicetalia orientalis Hamzaoğlu高度相关,其范围不延伸到安纳托利亚中部。

: Tribe Stachydeae with 12 genera were divided into two major clades: Melitis and Eurystachys clades consisting of all genera attributed to Stachydeae except Melittis . Recently, a broadly defined Eurystachys clade falling into 12 well-supported clades have been formally named in a phylogenetic nomenclature. In the present study, trichomes of 70 spp. from nine genera and pollens of 53 spp. from six genera were investigated using scanning electron microscopy (SEM) in order to draw the taxonomic conclusion of tribe Stachydeae. Trichome characters that can provide adequate variation in delimitation of taxa were: presence or absence of glandular or nonglandular trichomes, number of cells (uni-/bi-/multicellular), presence of extremely long trichomes (i.e. more than 1000 μm), presence of branched trichomes as well as type of glandular trichomes (peltate or capitate with three subtypes: sessile to subsessile, short-stalked and long-stalked trichomes). Among the investigated characters, extremely long simple trichomes and branched trichomes were apomorphic and were found in Eriostomum and Marrubiastrum clades, respectively. In addition, number of colpi, type of sculpturing as well as shape of lumina as the main features of the investigated pollen grains afforded valuable characters especially in delimitation of several natural groups, i.e. Eriostomum clade, Empedoclea clade, Sideritis clade, Marrubiastrum clade, and Swainsoniana clade. Moreover, a close relationship among two annual clades of Sideritis each of represents a section, i.e. Hesiodia and Burgsdorfia , is suggested by our results. However, in both Stachys and Olisia clades which are morphologically heterogeneous, type of sculpturing shows variation and mostly useful in species discrimination. Overall, trichome and pollen characters can be useful in describing the natural groups within tribe Stachydeae along with other reliable morphological characters.
: Stachydeae族共有12个属,分为两大支系:Melitis和Eurystachys支系,包括除Melittis外所有属于Stachydeae的属。最近,一个广泛定义的Eurystachys分支归入12个支持良好的分支,在系统发育命名法中被正式命名。本研究利用扫描电镜(SEM)对9属70种蝇的毛状体和6属53种蝇的花粉进行了研究,以期得出竹足科的分类结论。毛状体特征可以提供足够的分类划分差异,包括腺状或非腺状毛的存在与否,细胞数量(单/双/多细胞),极长毛的存在(即超过1000 μm),分支毛的存在以及腺状毛的类型(盾状或头状,有三种亚型:无柄到近无柄,短柄和长柄毛)。在所调查的性状中,极长的简单毛和分枝毛是无形的,分别在Eriostomum和Marrubiastrum分支中发现。此外,花粉粒的孔洞数量、雕刻类型和光腔形状等主要特征,特别是对Eriostomum枝、Empedoclea枝、Sideritis枝、Marrubiastrum枝和Swainsoniana枝等自然类群的划分提供了有价值的特征。此外,我们的研究结果还表明,Sideritis的两个年生分支(即Hesiodia和Burgsdorfia)各代表一个剖面,它们之间存在密切的关系。然而,在Stachys和Olisia两种形态异质的进化枝中,雕刻类型表现出变化,并且主要用于物种区分。总体而言,毛状体和花粉特征与其他可靠的形态学特征一起,可用于描述系内的自然类群。

: Abiotic stresses are serious environmental factors militating against the production of many crops around the world. The consequence of this, is the difficulty of meeting the demands of the increasing world population. Aside from other negative effects, reduction in photosynthesis is an important feature of abiotic stresses. Abiotic stresses limit photosynthesis in a number of ways. The reduction in ribulose 1, 5-bisphosphate carboxylase/oxygenase (Rubisco) content and activity is one of the paramount ways through which abiotic stresses affect photosynthesis. Rubisco is the CO 2 fixing enzyme of photosynthesis and also catalyses the photo-respiratory carbon oxidation. The enzyme has low turnover and also copes with competitive inhibition by O 2 . Hence, manipulating the enzyme in order to boost photosynthesis has been the target of scientists, especially in stressed environments. Based on recent studies, the mechanism of the harmful effects of abiotic stresses on Rubisco is examined in this review. In addition, the prevalent ways through which Rubisco can be made to thrive well despite the various abiotic stresses are evaluated. This review paper also outlines practicable approaches to promote existing ways of enhancing Rubisco tolerance to abiotic stresses in order to produce more crops with higher stress resilience.
:非生物胁迫是严重的环境因素,阻碍了世界各地许多作物的生产。其后果是难以满足日益增长的世界人口的需求。除了其他负面影响外,光合作用的减少是非生物胁迫的一个重要特征。非生物胁迫在许多方面限制光合作用。核酮糖1,5-二磷酸羧化酶/加氧酶(Rubisco)含量和活性的降低是非生物胁迫影响光合作用的重要途径之一。Rubisco是光合作用的CO2固定酶,也催化光呼吸碳氧化。该酶具有较低的周转率,并且还能够应对O2的竞争性抑制。因此,操纵酶以促进光合作用一直是科学家们的目标,尤其是在压力环境中。根据近年来的研究,本文对非生物胁迫对Rubisco的有害作用机制进行了综述。此外,还评估了Rubisco在各种非生物胁迫下生长良好的普遍方式。这篇综述文章还概述了推广提高Rubisco对非生物胁迫耐受性的现有方法的可行方法,以生产更多具有更高抗逆性的作物。

: Inocybe viscida sp. nov., a novel species found in a forest with old trees of Pinus brutia and tertiary relict endemic Liquidambar orientalis in coastal area of southwestern Turkey, is described and illustrated. We present this new species based on morphological and molecular data from nuclear rDNA internal transcribed spacer region (ITS1-5.8SITS2 = ITS) and the portions of nuc 28S rRNA (LSU) gene. Comprehensive description, field photographs, line drawings of the microscopic features and comparisons with phenetically similar taxa and phylogenetically related species are discussed.
描述并说明了在土耳其西南部沿海地区的一种新种Inocybe visicida sp. nov.,该新种是在有古松(Pinus brutia)和第三纪特有的东方松(Liquidambar orientalis)的森林中发现的。我们根据核rDNA内转录间隔区(ITS1-5.8SITS2 = ITS)和nuc 28S rRNA (LSU)基因部分的形态学和分子数据提出了该新种。本文讨论了其综合描述、野外照片、显微特征的线条图以及与表型相似的分类群和系统发育相关的物种的比较。
