“…Anatomical research is restricted to vegetative organs, such as the roots, stems, and leaves. The paraffin method was used to prepare anatomical preparations, followed by Purnobasuki et al (2017). Compared to floral/reproductive anatomy, vegetative anatomy is more frequently used as a taxonomic characteristic (Hasanuddin and Fitriana 2014).…”

Abstract. Purnobasuki H, Rakhashiwi GA, Junairiah, Wahyuni DK, Putra RE, Raffiudin R, Soessilohadi RCH. 2022. Morpho-anatomical characterization and DNA barcode of Cosmos caudatus Kunth. Biodiversitas 23: 4097-4108. Secondary metabolites in plants have various benefits, therefore their distribution in plant body parts is important to study. The identification process of plants should be conducted using several characters, including morphological and molecular data. This study aimed to identify and confirm Cosmos caudatus Kunth using morpho-anatomy characters and DNA barcodes. The plants used were three samples taken from the Husada Graha Famili Park, Surabaya. The morpho-anatomical investigation was carried out descriptively, while the DNA barcoding study was processed by amplifying and sequencing the rbcL and matK genes. Morphological studies indicate that the roots and stems of C. caudatus are similar to the organs of dicots shrubs in general. The leaves have a pinnate type with two different colors on each side of the leaf. Compound flowers are cup-type with two types of flowers, namely disc flowers and ray flowers. Based on anatomical observation, all vegetative organs have the same tissue as dicotyledonous plants. The anatomical characteristic of C. caudatus lies in its trichomes due to its anthocyanin content and stomata which are anomocytic and anisocytic types. DNA barcoding results showed that the three sample plants had identical similarities with several Cosmos genera contained in the GenBank database with percentage identities values ??above 98%, query covers 96-100%, and e-values ??of 0.

“…Similarly, Li et al [29] working on the rhizosphere and non-rhizosphere zones of a mangrove forest in China found MPs in the rhizosphere to be almost double that of the non-rhizosphere. The root system (adventitious) of A. marina consists of four root types, i.e., the pneumatophore, feeding root, anchor root and cable root [88]. Higher pneumatophore densities may thus facilitate the trapping of MPs, and the below-ground, extensive array of roots facilitates the deposition/compacting of MPs within sediment.…”

Plastic and, particularly, microplastic (MP) pollution is a growing research theme, dedicated largely to marine systems. Occurring at the land–sea interface, estuarine habitats such as mangroves are at risk of plastic pollution. This study compared MP pollution (level, morphotype, polymer composition, size and colour) across four South African estuaries, in relation to the built and natural environment. Mouth status, surrounding human population densities and land-use practices influenced the level and type of MP pollution. Systems that were most at risk were predominantly open estuaries surrounded by high population densities and diverse land use types. Microplastic levels and the diversity of types detected increased with increasing levels of anthropogenic disturbance. Overall, microfibres dominated in estuarine water (69%) and mangrove sediment (51%). Polyethylene (43%) and polypropylene (23%) were the dominant polymers overall. Weathered fishing gear, weathered packaging items and run-off from urban/industrial centres are probable sources of MP pollution . Increased run-off and river input during the wet/rainy season may explain the markedly higher MP loads in estuarine waters relative to the dry season. By contrast, MP deposition in mangrove sediment was higher during the dry season. Sediment MP abundance was significantly positively correlated with both pneumatophore density and sediment size (500–2000 µm). This study highlights the role of mangroves as MP sinks, which may limit movement of MPs into adjacent environments. However, under conditions such as flooding and extreme wave action, mangroves may shift from sinks to sources of plastic pollution.

“…This method includes several stages, such as collecting plants from the field, washing, fixing, dehydrating, dealcoholizing, infiltrating, blocking in pure paraffin, slicing, gluing, staining, and covering (Santos et al 2016;Susetyarini et al 2020). The safranin and fast green were used for plant tissue staining (Purnobasuki et al 2017). The anatomical characters such as tissue type, secretory cells, and other discriminate characters were described and analyzed.…”

Abstract. Wahyuni DK, Mukarromah SR, Rakhmad P, Ilham M, Rakashiwi GA, Indriati DT, Yoku BF, Purnobasuki H, Junairiah, Prasongsuk S. 2022. Morpho-anatomical characterizationand DNA barcoding analysisof Pluchea indica (L.) Less.. Biodiversitas 23: 4272-4282. Pluchea indica (L.) Less. is a member of the Asteraceae family and is popular as a medicinal plant. It is very important to authenticate plants using various markers to confirm the labeling of plants and to reveal the bioactive compounds for pharmaceutical research. This study aims to characterize the morpho-anatomical and DNA barcoding aspects of P. indica. Three samples obtained from Taman Husada Graha Famili, Surabaya, Indonesia were used in this study. Morphological studies were carried out descriptively, while the paraffin method was used for anatomical observations. DNA barcoding analysis was performed by amplifying and aligning the rbcLand matKgenes. Morphologically, P. indicahas organs like Asteraceae plants in general, with specific characteristics in leaves and flowers. P. indica has an anatomical organ similar to that of Asteraceae plants globally, only that there are specific histological features on its leaves, including anomocytic stomata, glandular cells, and multicellular glandular trichomes. Alignment and reconstruction of the phylogenetic tree showed that the sample plants were closely related to P. indica in the GenBank database. Based on morpho-anatomical characters and DNA barcodes, the plant under study was confirmed as P. indica L. (Less).
