(Brassicaceae) in Turkey https://www.banglajol.info/index.php/BJPT/article/view/50662 <p>The present study was designed to analyse the anatomy of the vegetative and reproductive parts of Turkish <em>Iberis </em>species from a systematic point of view. Samples of leaves, stems, roots, fruits, and seeds of each species were collected, fixed, and processed according to the paraffin method for light microscopy. The numerical analysis derived from 11 anatomical characteristics showed that the number and dimensions of vessels in the root, presence of aerenchyma in the leaf, number and dimensions of palisade parenchyma, and mesophyll type were useful for grouping the <em>Iberis </em>taxa. The testa was composed of four layers: the epidermis, subepidermis, compact tissue, and parenchyma. The testa thickness was a significant character to distinguish the investigated <em>Iberis </em>species. In this study, the traditional classification of Turkish <em>Iberis </em>species was mostly congruent with the dendrogram generated vegetative anatomical properties.</p> <p>Bangladesh J.

(Brassicaceae) in Egypt https://www.banglajol.info/index.php/BJPT/article/view/50664 <p><em>Brassica tournefortii </em>Gouan. (family Brassicaceae) is one of the five species in the Egyptian flora. Its populations showed notable morpho-plasticity with taxonomic debates, which were not yet resolved. The current study was carried out to assess the species morpho-plasticity and its molecular identity based on ISSR. The study was applied to 27 herbarium and fresh populations, representing all the species distribution ranges in Egypt. The taxonomic revision included 70 morphological characters, revealed five distinct Forms (1-5), radical leaf, and fruit provided the major distinguishable traits among the studied 70 morphological characters based on them the morphologic key is provided to delimit these forms. The pollen grain features using SEM are a pioneer at the infra-specific level, two shapes observed the subprolate (Forms 1&amp; 3) and prolate (Forms 2, 4 &amp; 5). Furthermore, the exine micro-features possess taxonomic value at the infraspecific level. The cluster analysis based on ISSR data revealed two clusters congruent to those developed by morphological and pollen traits. The ISSR results indicated that the species morpho-plasticity is genetically controlled. The study highlights the importance of the multidisciplinary approach to assess the taxonomic identity at the infra-specific level, for the auto-taxonomy of morpho-plastic species.</p> <p>Bangladesh J.

The most important reason of the species diversity in Turkey is its location and geomorphological structure which increase climatic effects and seperate Turkey into different phytogeographic regions. Furthermore, hybridization behaviours which frequently observed between oak species, genetic drift, gene flow and ecological factors cause morphological variations in the plants species. All of these factors make it difficult to define the species concept for plant groups like oaks. Therefore, the region covering 18S rRNA gene/ ITS1/ 5.8S rRNA gene/ ITS2/ 25S rRNA gene and secondly intergenic spacer (IGS)/ 5S rRNA gene for barcoding were obtained from genbank and used as a useful tool for the determination and solution of the phylogenetic relations of taxonomically problematic species, also these barcoding regions were compared with each other according to species recognition ability for oak species. As a result, it can be stated that both barcoding regions have high variable sites based on sequence information to identify the species and evaluate relationships of species studied.</p> <p>Bangladesh J.

(Cyanobacteria) newly recorded off the Southwest coast of Bangladesh https://www.banglajol.info/index.php/BJPT/article/view/50668 <p><em>Trichodesmium erythraeum </em>Ehrenberg 1830 (Cyanobacteria) has been described and newly recorded from three km off the west coast of the St. Martin’s Island (SMI), Cox’s Bazar, Bangladesh. The Red Sea algal bloom was narrowly elliptical raft-like loose aggregates 20-40 cm long, 4-8 cm wide and 2-3 cm thick. Volume of small and large Sea sawdust were 160×10-6 to 960×10-6 m3 consisting of 25-153 millions flat tuft or spindlelike colonies measured 830-1500 μm long and 155-260 μm wide with 13-16 filaments laterally in the median region. Sheath was present around each trichome even covering the tip cell wall the feature has so far not been reported for the <em>Trichodesmium </em>spp. Because of most likely sticky nature of the sheath 300-600 μm long filaments of 195-450 formed compact colonies without colonial sheath around. In interior filaments cells were rectangular 7-10 μm long and 6.3-10 μm wide with abundant gas vacuoles, bluish-green red, no diazocytes developed and without calyptrae. Cells of peripheral filaments were without gas vacuoles, cytoplasm disorganized, appearing necrotic with glycogen granules, and produced convex to sickle-shaped four-layered calyptra consisting of outermost sheath followed by outer extra thick wall, tip cell wall and inner extra thick wall on the tip cell. Calyptra was also produced on tip cells of tapered filaments. Presence of sheath around each trichome binding all filaments into a colony without colonial sheath described here, and presence of nitrogenase containing diazocytes in interior filaments, both temporal and spatial segregation of N2 fixation and photosynthesis within the photoperiod described and discussed in literature made the authors to consider <em>T. erythraeum </em>Ehr. a distinct taxon under family Microcoleacece.</p> <p>Bangladesh J.

And <em>Monodora </em>Engl. (Annonaceae) from West-Central Africa. Twelve species of tribe <em>Monodoreae </em>were investigated on the basis of micromorphology of midrib characters with the aid of light microscopy. The study provided important taxonomic characters which aid delineation of inter and infrageneric species within the duo genera. The generic features include centrally positioned, open collateral vascular bundle and furrow shaped midribs which are diagnostic to the genera.U shaped vascular bundles are present in most of the species with inviginating or expanded endings while marginal traces vary from 2 to 4. The presence of keel protrusion at abaxial surface established a closer affinity among <em>M. angolensis, M. crispata, </em>and <em>M undulata </em>with additional features species were delimited. Other variable useful features of midrib encountered are trichomes, parenchyma, collenchyma and sclerenchyma, and adaxial and abaxial shape. The midrib characters have been used to prepare an indented dichotomous key to delimit the species in the genera studied.</p> <p>Bangladesh J.

DNA barcoding was used as a tool for molecular identification of <em>Zanthoxylum armatum </em>DC<em>. </em>species from Balakot Pakistan. In the present study four DNA barcodes including <em>matk, rbcl, ITS </em>and <em>trnH-psbA </em>were used. The sequenced data were analyzed by using BLASTn at NCBI, FASTA and Mega 7.0 software. During PCR analysis, 3 DNA barcodes <em>ITS, rbcl </em>and <em>trnh-psbA </em>were successfully amplified and showed the 100% sequencing success. Furthermore, these barcode markers showed 99-100% sequence similarity with the reference sequences at the BLASTn. The further analysis revealed the sequence similarity of investigating marker with <em>Zanthoxylum armatum </em>(MH016484.1), <em>Zanthoxylum nitidum </em>(FN599471.1) and <em>Zanthoxylum bungeanum </em>(MF097123.1) respectively. The current finding provides the basis for sequenced data of <em>Z. armatum </em>to be used in future for molecular discrimination among the plant species from Pakistan and it is concluded that combination of diverse kind of barcoding markers could be helpful in proper identification of species at lower taxonomic level.</p> <p>Bangladesh J.

In this work, we observed modifications of forest and pre-forest structures according to bioclimatic variations. However, in this region, the xericity of the climate is not the only factor destroying the plant cover, anthropization is also a degradation factor. While being aware of the negative consequences, man, through their abusive cultivation, illegal logging, overgrazing, urbanization, the depletion of natural resources;, inhibits the evolution of vegetation, participates in the replacement of a rich plant cover by another and more xerophytic plant cover with thorny and/or toxic feature. The landscape is dominated, for the most part, by open and degraded formations based on therophytes and chamaephytes, linked to Rosmarinetea and Cisto-Lavanduletea. The tree structures in Hafir and the Moutas reserve, still occupy only minimal areas subject to the destructive actions of man and his flock. These formations are still linked to the <em>Quercetea ilicis</em>. These ecosystems are marked by a regressive evolution (forest, pre-forest, scrub, scrubland and therophytization).</p> <p>Bangladesh J.

It has a wide range of applications such as drug delivery, coatings, energy generation and storage, gas separation, water purification, sensor fabrication, and catalysis. Most of the widely used carbon materials are graphene and carbon nanotubes. Nonrenewable precursors (e.g., natural gas), toxic chemicals, and complex synthesis methods are often required for their preparation, limiting their wide practical applications. Besides these, biomass-derived carbons are attractive materials as they can be prepared simply from renewable biomass. However, their practical applications' success partially depends on their properties like size, shape, porosity, and presence of heteroatoms, which can be controlled by selecting the proper type of biomass, activating agent, and preparation method. It is noted that different species of plants have different chemical compositions and textures. This mini-review summarizes our group's recent sophisticated developments in agricultural-bio-waste-derived carbonaceous materials, including nanomaterials for electrocatalytic water splitting, electrochemical sensors, supercapacitors, water splitting, water treatment, gas separation, and enhance oil recovery. This offers valuable insights and essential guidelines towards the future design of agro-waste derived carbonaceous materials in various applications.</p> <p>Bangladesh J.
