Abstract

Moss is a plant in the Bryophyta division that has many benefits, especially for the ecosystem. Research on moss diversity has not been widely carried out in the Sulawesi area, especially West Sulawesi. The aim of this study was to determine the diversity of mosses in the forest area of Taupe Village, Mamasa District, Mamasa Regency, West Sulawesi. The sampling was carried out by the cruised method. After that, samples was identified and collected in the form of a herbarium. The research location was divided into 3 stations based on topographic conditions. The results showed that there were 26 species of mosses belonging to 19 families, including: Andreaeaceae, Aneuraceae, Bartramiaceae, Brachytheciaceae, Bryaceae, Dicranaceae, Hookeriaceae, Hypnodendraceae, Jungermaniaceae, Lejeunaceae, Lepidoziaceae, Marchantiaceae, Notothyladaceae, Plagiochilaceae, Pleuroziaceae, Porellaceae, Scapaniaceae, Sematophyllaceae, and Sphagnaceae. The diversity analysis showed that mosses in the Taupe Village Forest had high diversity (H'=3,088), high evenness (E=0,948), low dominance (C=0,051), and medium species richness (R1=4,402).

Abstract

Phalaenopsis amabilis (L.) Blume or moon orchid is a type of orchid that has high economic and aesthetic value, but the flowering time is relatively long. Induction of flowering was carried out by inserting the PaFT gene with the ubiquitin promoter in the plant to obtain transgenic candidate plants (transformants). Transformant plants were grown in New Phalaenopsis (NP) medium for 40 weeks. Molecular analysis on transformant plants obtained P. amabilis transgenic. Amplification with ubiquitin (forward) and T-Nos (reverse) and deg PaFT primers in transgenic plants obtained DNA sequences of 1137 bp and 533 bp, while for non-transformant plants with deg PaFT primers, DNA bands of 1500 bp were obtained. The development of transgenic and non-transformant plants were then compared at 10, 20, 30, and 40 weeks of age. The results showed that transgenic plants produced multiple shoots/multishoots and longer roots compared to the roots of non-transformant plants. According to the literature study, there are morphological differences in some plants that carry the flowering locus T gene compared to nontransforman/wildtype plants.

Abstract

Identification and inventarisation of fish species is important for fisheries data. Information regarding fish species sold within the local markets of Denpasar city-Bali have not been collected and written as a good data, especially identification using molecular methods and comparison between local name and species name. Therefore, this study aims to identify species of pelagic fish sold within markets of Denpasar city using control region mitochondrial (mtDNA) marker. A total of 7 samples of pelagic fish were collected from 2 markets within Denpasar city, in the form of full body fish, fish that has been boiled, and boiled fish body parts. DNA samples were amplified at the control region of mtDNA, and obtained the sequence length of 508-527 bp. Identification was conducted using BLAST methods and phylogenetic analysis. The result showed that the samples were identified as 4 species, i.e. Auxis rochei, Auxis thazard, Thunnus albacares, and Thunnus obesus. Through this study, we also revealed that fish with the local name “ikan tongkol” was the species of Auxis rochei, Auxis thazard, Thunnus albacares, meanwhile fish known as the local name “ikan cakalang” was the species of Thunnus obesus. The results of this study was expected to be a preliminary study about the diversity of fish sold within markets in Denpasar city, and also as the additional genetic data for pelagic fish within Bali waters. This will also act as the additional information for the methods of fish species identification.
