Abstract

Tanaman kacang panjang adalah komoditas pertanian yang sangat berpotensi untuk dikembangkan karena mudah dibudidayakan dan pangsa pasar cukup tinggi, namun masih ada permasalahan dalam memenuhi kebutuhan benih dan masih rentan terhadap hama dan penyakit. Oleh karena itu perlu dilakukan upaya peningkatan produksi dan induksi variasi kacang panjang. Salah satu metode yang dapat digunakan adalah kultur jaringan untuk induksi variasi somaklonal dan/atau pembentukan tanaman transgenik. Penelitian ini bertujuan untuk mengetahui pengaruh variasi waktu inisiasi kalus dan pengaruh pemberian ZPT terhadap pertumbuhan kalus eksplan kotiledon kacang panjang. Sterilisasi biji dilakukan dengan menggunakan detergen, natrium hipoklorit 10%, alkohol 70% dan akuades steril. Hasil penelitian menunjukkan bahwa variasi waktu inisiasi kalus pada media MS dengan penambahan ZPT 2,4-D serta penggunaan beberapa variasi ZPT pada subkultur mampu menginisiasi kalus dan mempengaruhi ukuran kalus, warna kalus, serta persentase browning eksplan kotiledon kacang panjang. Waktu inisiasi kalus 4 minggu dengan kombinasi konsentrasi BAP 2 ppm dan IAA 0,1 ppm menghasilkan ukuran kalus paling besar dan warna kalus putih kecoklatan. Penambahan ZPT saat subkultur memiliki persentase browning yang lebih kecil dari perlakuan tanpa ZPT.

Abstract

Agarwood is a highly valued fragrant wood and has been traded for its economic and medicinal value. The resin in agarwood is used to produce high value downstream products such as fragrances, oils, medicines, teas, cosmetic carvings, and luxury goods where the demand for these products remains consistent. Most of the agarwood-producing trees come from the genera of Aquilaria and Gyrinops, which belong to the Thymelaeaceae (Malvales) family. In addition, Aquilaria malaccensis and Gyrinops versteegii are the most cultivated agarwood producing trees in Malaysia and Indonesia, respectively. Nevertheless, the survival of the species is threatened by the overharvesting of the forest, which leads to strict regulation by the exporting nations for international trade. Interestingly, agarwood plantation is a viable option which able to generate income for local population without causing any harm to the ecosystems. However, a lack of research on seedling preparation for large-scale plantations, and the optimum nutrient management practices have slowed down the agarwood industry. Hence, this review article will highlight the most effective strategy for enhancing agarwood cultivation by focusing on proper nutrient management to boost agarwood production.

Abstract

In this study, the genome of an endemic Sulawesi’s plant, Medinilla tapete-magicum was sequenced using Illumina NextSeq 500 and assembled the whole chloroplast genome. Results showed that the cpGenome is 155,602 bp in size with typical quadripartite structure of a large single copy (LSC) region (85,409 bp), a short single copy (SSC) region (16,629 bp), and a pair of inverted repeats (IRs) regions (26,782 bp). The cpGenome is composed of 132 genes, which consists of 87 protein coding genes, 37 tRNAs, and 8 rRNAs. The sliding window analyses showed that psbB-psbH and ndhF-rpl32 can potentially be used as markers. Microsatellite motifs of mononucleotide A and T dominated in the cpGenome. The phylogenetic trees from the concatenated 76 shared protein coding gene sequences showed the Medinilla clade was monophyletic and M. tapete-magicum is a sister species in the SE Asian clade which contain M. magnifica and M. speciosa.

Abstract

Black betel (Piper betle L. var. Nigra) can be found in Indonesia and has been proven to have antimicrobial activity so it has the potential to be used as a medicinal plant. Tissue culture can be used to produce seeds that are the same as the parent plant in large, uniform quantities and to produce secondary metabolites from cell suspension cultures. The sterilization method is a very important initial stage for in vitro plant growth, so optimizing sterilization is the aim of this research. The planting materials used are black betel leaves and nodes. Optimization of the sterilization method was carried out using variations in materials and sterilization time duration. The ingredients used were dish soap, bactericide, fungicide, sodium hypochlorite solution, vinegar, alcohol, and Plant Preservative Mixture (PPM). The medium for leaf explants is MS with 2,4-D and for nodes was MS with BAP. Data on the number of contaminated explants were analyzed using the SPSS program. The results of analysis of variance (ANOVA) showed that the optimal sterilization of black betel leaves was using a fungicide solution for 30 minutes, 5% sodium hypochlorite solution for 10 and 15 minutes, vinegar for 7 minutes, 70% alcohol for 10 minutes and PPM for 1 minute with a 22.1% of explants contaminated. Sterilization by rubbing the nodes under running water and the use of vinegar to sterilize black betel nodia resulted in a significantly lower percentage of contamination (73.3%, P<0.05) compared to the method where the leaves were not cleaned by rubbing under running water and no vinegar.

Abstract

The Cattleya genus is one of the most commercially valuable orchids. Identifying these orchids based on morphological and phenotypic traits has been challenging. Accurate identification is crucial for distinguishing between native and hybrid species and determining the protected status of certain Cattleya orchids. This research explored potential markers using nrDNA and matK locus for DNA barcoding of the Cattleya genus through an in silico approach. All sequences were collected from the NCBI and analyzed using ClustalX2 for alignment, BioEdit for conversion, and MEGA11 for phylogenetic tree construction. The results revealed that nrDNA showed higher genetic variation compared to matK. However, neither phylogenetic tree could discriminate species precisely, as some Cattleya species were positioned closer to the outgroup. These findings can be used as a reference to support identification of Cattleya using molecular marker. Keywords: Cattleya, matK, molecular barcode, nrDNA
