Abstrak. Penelitian bertujuan untuk mengetahui morfologi dan anatomi tipe stomata dari famili piperaceae yang terdapat di Kota Langsa. Penelitian diharapkan dapat memberikan informasi kepada masyarakat dan mahasiswa tentang morfologi dan anatomi tipe stomata tanaman dari famili piperaceae. Hasil penelitian dapat dijadikan sebagai data awal tentang morfologi dan anatomi tumbuhan dari famili piperaceae yang terdapat di Kota Langsa.  Metode yang digunakan diskriptif kualitatif untuk menggambarkan dan menginterpretasi tipe stomata pada daun  famili piperaceae.  Hasil penelitian tumbuhan famili piperaceae yang ditemukan di daerah kota langsa sebanyak lima spesies tanaman yaitu lada (Piper ningrum), suruhan (Peperomia pellucida), Sirih Kuning (Piper betle), sirih hijau (Piper betle), dan Merah (Piper crocatum).  Maka dapat diketahui bahwa secara morofologi tumbuhan famili piperaceae merupakan kelompok tumbuhan dikotil. Pada umumnya family piperaceae memiliki ciri-ciri  dengan sistem perakaran tunggang, dengan ciri-ciri batangnya vobubilis disertai dengan tampaknya nodus pada batang yang disertai dengan adanya sulur namun ada juga berbatang herba yang tumbuh tegak dengan percabangan batang monopodial. Walaupun kelima spesies tumbuhan tergolong dalam satu famili yang sama yaitu piperaceae, namun secara morfologi maupun anatomi tipe sel stomatanya memiliki perbedaan pada masing-masing spesies. Dari hasil penelitian ditemukan tiga tipe stomata pada tumbuhan family piperaceae yaitu Tipe stomata anomocytic, tipe tertracytic dan tipe cyclocytic.Kata kunci: morfologi,  anatomi, tipe stomata, famili piperaceae.  Abstract. The aim of this research is to know the morphology and anatomy of stomata type from piperaceae family in Langsa City. Research is expected to provide information to the community and students about the morphology and anatomy of plant stomatal types from the piperaceae family. The results can be used as early data about the morphology and anatomy of plants from the family piperaceae found in Langsa City. The method used is descriptive qualitative to describe and interpret the type of stomata on the leaves of the family piperaceae. Piper betel (Piper betle), Piper betle (Green Piper betle) and Red (Piper crocatum) betel (Piper betle), Piper betle (Piper betle), and Piper betel (Piper betel) were found in five different species of pepper (Piper ningrum). So it can be seen that the morofologi plant family piperaceae is a group dikotil plants. In general, the family piperaceae has characteristics with the root system of tunggang, with the trunk of vobubilis trunk accompanied by apparently nodes in the stem accompanied by the presence of tendrils but there is also trunked herbs that grow upright with the branching of monopodial rods. Although the five plant species belong to the same family of piperaceae, morphologically or anatomically, the stomatal cell type differs in each species. From the results of the study found three types of stomata in family plant piperaceae that is Anomocytic stomata type, tertracytic type and cyclocytic type.Keywords: morphology, anatomy, stomata type, family piperaceae

The Family

For several decades, it has been known that oestrogens are essential for human health. The discovery that there are two oestrogen receptors (ERs), ERalpha and ERbeta, has facilitated our understanding of how the hormone exerts its physiological effects. The ERs belong to the family of ligand-activated nuclear receptors, which act by modulating the expression of target genes. Studies of ER-knockout (ERKO) mice have been instrumental in defining the relevance of a given receptor subtype in a certain tissue. Phenotypes displayed by ERKO mice suggest diseases in which dysfunctional ERs might be involved in aetiology and pathology. Association between single-nucleotide polymorphisms (SNPs) in ER genes and disease have been demonstrated in several cases. Selective ER modulators (SERMs), which are selective with regard to their effects in a certain cell type, already exist. Since oestrogen has effects in many tissues, the goal with a SERM is to provide beneficial effects in one target tissue while avoiding side effects in others. Refined SERMs will, in the future, provide improved therapeutic strategies for existing and novel indications.

AbstractThis study describes the nematode community in a semi-natural grassland and investigates if certain individual plant species can cause a spatial structure in the nematode fauna. Nematode communities were analysed in soil under Trifolium repens, Festuca ovina and from randomly taken samples. Seventy-nine nematode genera were identified. Some of the species found have not previously been reported from Sweden. Multivariate analysis separated the nematode communities associated with the two selected plant species from each other, and several individual nematode genera differed in abundance between the plant species. Trifolium repens supported greater populations of the plant feeder Tylenchorhynchus and the bacterial feeders Eucephalobus, Chiloplacus, Eumonhystera and Panagrolaimus, but fewer numbers of the bacterial feeder Achromadora. Soil under F. ovina contained more nematodes from the family Alaimidae. A comparison is given with other studies from grassland systems in Sweden.

"The floral tips of the plant species Lythrum salicaria L. represent a rich source of total polyphenols, among which with the largest share we mention tannins, and this is why this plant material has a standardized monograph in the European Pharmacopoeia 10.0th edition. According to the literature accessed so far, the plant material has antioxidant, anti-inflammatory, hemostatic, antibacterial and antifungal properties, along with modulatory action on carbohydrate metabolism. Powder microscopic examination is an important step in establishing the identity of the plant species used, highlighting elements specific to the aerial part such as spiral vessels of the stem, fragments of the spongy mesophyll with calcium oxalate clusters cells and anomocytic stomata. The application of the SeDeM method on dried plant extracts represents an innovative trend in pharmaceutical technology and contributes to the collection of data in a structured and standardized form. In this paper, the functions and applications of the SeDeM expert system are illustrated upon the freeze-dried extract of Lythri herba for the purpose of easier identification and standardization. Future applications may include obtaining chewable gums or tablets by direct compression."

Although most plant species are photosynthetic, several hundred species have lost the ability to photosynthesize and instead obtain nutrients via various types of heterotrophic feeding. Their plastid genomes markedly differ from the plastid genomes of photosynthetic plants. In this work, we describe the sequenced plastid genome of the heterotrophic plant Rhopalocnemis phalloides, which belongs to the family Balanophoraceae and feeds by parasitizing other plants. The genome is highly reduced (18,622 base pairs vs. approximately 150 kbp in autotrophic plants) and possesses an extraordinarily high AT content, 86.8%, which is inferior only to AT contents of plastid genomes of Balanophora, a genus from the same family. The gene content of this genome is quite typical of heterotrophic plants, with all of the genes related to photosynthesis having been lost. The remaining genes are notably distorted by a high mutation rate and the aforementioned AT content. The high AT content has led to sequence convergence between some of the remaining genes and their homologs from AT-rich plastid genomes of protists. Overall, the plastid genome of R. phalloides is one of the most unusual plastid genomes known.

Hancornia speciosa Gomes, known as mangaba or mangabeira, is a plant species of the family Apocynaceae with botanical varieties occurring in several regions of Brazil. The species is of considerable ecological and economic importance in the food, timber, latex and medicinal industries. Four different varieties of H. speciosa occur in Cerrado. Anatomical characteristics contribute to the taxonomic identification of plants, including those of isolated organs such as leaves, roots, stems, fruits and seeds. Thus, the present work investigated the anatomical characteristics and the location of the main classes of secondary metabolites of the fruits of H. speciosa var. pubescens, H. speciosa var. gardneri, H. speciosa var. speciosa and H. speciosa var. cuyabensis to assist in distinguishing the varieties. Fruits were collected, preserved and fixed following usual methods for anatomical and histochemical analyses. All varieties under study showed similarities in anatomical characteristics and in the distribution of metabolites in the fruits, with the exception of the anatomy of the exocarp, where the occurrence of trichomes differed among the varieties of H. speciosa.

This article presents data on the rooting of green cuttings of the studied species of ornamental trees and shrubs in a greenhouse with a misting system. We accounted the number of days from planting to the root formation and the number of rooted cuttings for each replication during our performance. We studied the influence of root formation stimulants on the rooting rate of various types of ornamental deciduous, flowering and coniferous plants. The effect of application of root formation stimulants is confirmed by the formation of a high-quality root system that is superior in length to those that were vegetated without “Kornevin”. However, the use of root formation stimulants is not advisable on shrubby cinquefoil, common privet and common lilac “Mademoiselle Casimir Perier”, because there is practically no increase in the rooting rate of cuttings in these plant species, compared to the control plants.

Tanean Lanjhang merupakan bentuk rumah tradisional Madura yang memiliki komponen-komponen yang di antaranya adalah Langghar (Musholla), rumah utama yang diikuti rumah-rumah lainnya yang pada umumnya berderet dari Barat ke Timur, sesuai dengan urutan dalam keluarga, dapur, kandang, dan Tanean (pekarangan). Pada penelitian ini dibahas tentang karakteristik ruang pada rumah tradisional Tanean Lanjhang di Desa Bandang Laok, Kecamatan Kokop, Kabupaten Bangkalan, Madura yang terfokus pada beberapa kelompok Tanean Lanjhang di Dusun Baktalbak. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan menganalisis hasil identifikasi karakteristik ruang pada masing-masing kelompok Tanean. Hasil penelitian menunjukkan bahwa pola Tanean Lanjhang yang hanya terdapat 1 rumah utama saja disebabkan oleh keterbatasan lahan untuk mendirikan rumah hunian baru, sehingga keluarga baru/muda harus membuat rumah hunian lain dengan pola Tanean Lanjhang juga. Selain itu terdapat persamaan bentuk ruang dengan ukuran ruang yang bervariasi, sesuai dengan fungsi dan kegunaan. Sementara itu, perbedaan pembatas ruang dan komponen ruang menunjukkan tingkat perekonomian yang berbeda Tanean Lanjhang is a form of  Madurese  traditional house  which have components  of Langghar (mosque), the main house followed by other homes that are generally rows from West to East, according to the order in the family, kitchen, stables, and Tanean (yard). This study discussed about the characteristics of space in a traditional house Tanean Lanjhang in the village of Bandang Laok, Kokop District, Bangkalan Regency, Madura, which focused on several groups of Tanean Lanjhang in Baktalbak village. The method used in this research is descriptive qualitative by analyzing space characteristics on each Tanean group. The results showed that the pattern  of Tanean Lanjhang with one main house was caused by the limitation of land to build a new residential house, so the new family must build another residential house with Lanjhang Tanean pattern also. In addition, there is a similarity of form of space with room sizes in vary according to the functionality and usability. While the difference  of  space  barrier  and  space  components  showed  the  different  levels of  the economy.
