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.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43141318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Distributional ecology of Noccaea vesicaria in relation to the Anatolian Diagonal","authors":"İlayda Dumlupınar, Hakan Gür, Barış Özüdoğru","doi":"10.55730/1300-008x.2765","DOIUrl":"https://doi.org/10.55730/1300-008x.2765","url":null,"abstract":": 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.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46033708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Olayinka","doi":"10.55730/1300-008x.2730","DOIUrl":"https://doi.org/10.55730/1300-008x.2730","url":null,"abstract":": 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.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49378355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salmaki","doi":"10.55730/1300-008x.2683","DOIUrl":"https://doi.org/10.55730/1300-008x.2683","url":null,"abstract":": 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.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46218761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
