Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

Arrhenia nivea is a new bryophilous species of Arrhenia from a valley in southwestern China'a subtropical monsoon humid climate zone.The species is characterized by pure white basidiomata with an irregularly discoid to cupulate 1.5-4.5 mm diameter pileus, reduced hymenium, nonamyloid basidiospores, lack of cystidia, the presence of clamps, and no incrusted pigment of the pileipellic hyphae. Phylogenetic analysis using ITS sequence data confirmed that it arised from a pathway separate from other species of Arrhenia.
Monoclonal Antibodies Against Methyl Glucuronoxylan Epitopes For Understanding Xylan Structure And Modification, Utku Avci
Turkish Journal of Botany
Lignocellulosic biomass is an abundant and renewable source that could be utilized for production of many bioproducts. It mainly consists of cellulose, hemicellulose, and lignin, all of which come together to form a recalcitrant wall that impedes production of bioproducts. In order to overcome the recalcitrant nature of the biomass, it is important to fully understand how cell wall components are synthesized and assembled. Xylan is one of the hemicellulosic components of the wall that contributes to recalcitrance. Xylan has substitutions on the backbone that are formed by the orchestration of many enzymes. For example, glucuronoxylan methyltransferases are responsible for …

Seed Morphology Of Some Taxa Of The Genus Euphorbia L. (Euphorbiaceae) In Turkey And Its Taxonomic Significance, Murat Kurşat, Bi̇rol Başer, Fahretti̇n Özbey, İrfan Emre
Turkish Journal of Botany
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 …

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 …
Seed Morphology Of Some Plantago (Plantaginaceae) Species In Iran And Its Systematic And Phylogenetic Implications, Saeed Mohsenzadeh, Masoud Sheidai, Fahimeh Koohdar
Seed Morphology Of Some Plantago (Plantaginaceae) Species In Iran And Its Systematic And Phylogenetic Implications, Saeed Mohsenzadeh, Masoud Sheidai, Fahimeh Koohdar
Turkish Journal of Botany
Plantago is a cosmopolitan genus with approximately 200 species and various infrageneric classifications have been reported. In this study, the seed morphologies of 19 species of Plantago from Iran were studied and documented in detail using scanning electron microscopy and light microscopy. The studied species were grouped by using statistical analyses such as a minimum spherical cluster method based on Euclidean distance, principal coordinate analysis, and multidimentional scaling. We have described four types based on the seed shape and states of the inner side of the studied seeds: convex- angular type, convex-elliptic type, flat-elliptic type, and concave-elliptic type. In this …

Turkish Journal of Botany
This paper revises the genus Nepeta for the family Lamiaceae for the Flora of Iraq project. We describe a new species, Nepeta iraqensis, and four new records Nepeta congesta subsp. cryptantha, N. stricta, N. lamiifolia and N. iodantha for Iraq. Lectotypes for six taxa are selected and comments on complex species are given. In addition, two new synonyms are given here for the first time. In all, we describe with identification keys, 19 taxa, three of which are endemic to Iraq.
Distributional Ecology Of Noccaea Vesicaria In Relation To The Anatolian Diagonal, İlayda Dumlupinar, Hakan Gür, Bariş Özüdoğru
Distributional Ecology Of Noccaea Vesicaria In Relation To The Anatolian Diagonal, İlayda Dumlupinar, Hakan Gür, Bariş Özüdoğru
Turkish Journal of Botany
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 …

The purpose of this project was to help children reach more developmental goals and to make outdoor play at the Jean Tyson Child Development Study Center more inclusive for all children. Children gain many developmental goals from playing outside and being exposed to other environments as compared to just being inside the classroom. Outdoor play should be as inclusive as indoor play and offer many different activities and outlets, just as the indoor classroom does. The implementation of this service-learning creative project was to add more versatility to the outdoor area at the University of Arkansas Jean Tyson Child Development …

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …
