Abstract

Tanaman cabai (Capsicum annuum) merupakan salah satu sektor pertanian terbesar di Indonesia. Tanaman cabai banyak dibudidayakan oleh masyarakat di Indonesia sampai produksinya diekspor ke luar negeri. Namun pada tahun 2015 produksi cabai di Indonesia mengalami penurunan dibandingkan tahun-tahun sebelumnya. Penurunan produksi cabai di Indonesia disebabkan karena adanya serangan organisme pengganggu tanaman salah satunya adalah Fusarium oxysporum yang menyebabkan terjadinya penyakit rebah tanaman. Fusarium oxysporum adalah jamur yang berada di tanah, dan beberapa strain F. oxysporum bersifat patogen terhadap tanaman dan bersifat sulit dikendalikan. PAL adalah enzim yang mengkatalis perubahan phenilalanin menjadi ammonia dan trans-sinamat yang merespon tekanan biotik dan abiotik seperti patogen, UV radiasi, dan suhu rendah. Tujuan dari penelitian ini yaitu, untuk mengetahui ekspresi gen penyandi Phenylalanin Ammonia Lyase (PAL) pada cabai (Capsicum annuum) sebagai respons terhadap Fusarium oxysporum. Metode dari penelitian ini meliputi penanaman dan pemeliharaan tanaman, inokulasi F. oxysporum ke tanaman cabai, isolasi RNA daun cabai, analisis ekspresi gen PAL dengan menggunakan qRT-PCR dan analisis data. Hasil dari penelitian ini adalah ekspresi gen PAL pada jam ke-6 terekspresi sedikit lebih tinggi daripada kontrol dan mengalami penurunan pada jam ke-48 dan ke-96. Penelitian ini dapat disimpulkan bahwa tidak ada peningkatan ekspresi gen penyandi Phenilalanine Ammonia Lyase pada daun tanaman cabai (Capsicum annuum) sampai dengan 96 jam setelah inokulasi.

Abstract

Yeast is a single-celled fungus that acts as epiphytes, endophytes or parasites. Yeast is divided into fermentative yeast and oxidative yeast. Fermentative yeast can produce primary and secondary metabolites. The role of fermentative yeast is widely used in the food industry, health and energy, so necessary to be explore fermentative yeast from sugarcane stems. The purpose of this study was to isolate fermentative yeast from sugarcane stems and identify molecular yeast based on the Internal Transcribed Spacer sequences (ITS). Isolation of epiphytic and endophytic yeast was carried out by spread plate of water soak sugarcane and sugar cane juice. Yeast isolation using 2 media, PDA and YGP with chloramphenicol. Morphological characterization was carried out by observing macroscopic and microscopic characteristics. Biochemical characterization was carried out by carbohydrate fermentation test and 50% glucose media growth test. Selected isolates were molecularly identified using Internal Transcribed Spacer (ITS) sequences. Primers used are ITS 1 and ITS 4. Phylogenetic analysis using Neighbor Joining from MEGA-6 program. The results of isolation obtained 7 yeast isolates characterized morphologically and biochemically. The based result of morphology and biochemical characterization were found 1 selected isolate with name Ed 1B. Selected yeast isolate have characteristics are round colonies, creamy white, shiny surface, raised elevation, wavy edges, ovoid cell shape, cell diameter 4,74µm, budding, glucose fermentation and sucrose fermentation, but not for lactose and grow well of 50% glucose media. The results of the Basic Alignment Search Tools (BLAST) are Ed 1B isolates had 99% homology with Kodamaea ohmeri species.

Abstract

Indonesia is a tropical country with highest level of biodiversity, especially in the agricultural sector. Chili (Capsicum annumm. L) is a very well-known and widely used agricultural product in the world, which makes chili becomes one of the most considerable national product. The chili production is oftentimes very susceptible to some diseases caused by virus, fungi, or bacteria. One of the most common diseases in chili cultivation is Fusarium wilt, which is caused by Fusarium oxysporum. This disease can cause a major loss and up to 50% crop failure. Many procedures have been done to find the best cultivar with a resistance trait to Fusarium oxysporum, including by observing and testing the chili’s genetic resistance. One of the resistance genes in chili is β -1, 3- glucanase-encoding gene, which produces an enzyme to hydrolize the cell wall of pathogenic fungi. This research aimed to determine the expression of the glucanase-encoding gene (CaβGlu) in chili as a response to Fusarium oxysporum infection. The methods including chili cultivation, F. oxysporum inoculation, isolation of chili leaves RNA, glucanase-encoding gene expression analysis using qRT-PCR, and data analysis. The result of CaβGlu gene expression is higher than the control in the first 6 hours after inoculation, and decreasing in the 48th and 96th hours. The conclusion was the infection of Fusarium oxysporum is activating the expression of CaβGlu gene which was expressed best in the first 6 hours after inoculation.

Abstract

Bacillus halodurans strain CM1 was an Indonesia alkalothermophilic bacteria isolated from Cimanggu Hot Spring, Bandung, West Java. The activity of alkalo thermophilic protease enzyme from B. halodurans CM1 was detected. Nowadays, alkalothermophilic protease enzyme was applied for the eco-friendly industrial purpose, for example, as additive substance in detergent product. For the production and application of protease in the future, the cloning of protease gene from B. halodurans CM1 into E. coli was conducted. The protease gene was isolated from B. halodurans by PCR approach using primers designed based on the GenBank database. The PCR product then ligated into pGEM-T Easy vector, transformed into Escherichia coli DH5α, verified, and analyzed using DNA sequencing and bioinformatic tools BLAST. The results showed that 1086 bp protease gene was obtained and had 99% similarity with that of alkalostable protease from B. halodurans C-125. When the culture of this positive recombinant E. coli DH5α containing the protease gene spotted onto calcium caseinate agar, the clear zone appeared after incubation at 50 °C. It showed that the protease gene was expressed in this recombinant E.coli DH5α.

Abstract

T Phosphate solubilizing bacteria are soil bacteria that can dissolve phosphates from insoluble phosphate bonds so that they can be absorbed by plants. Phosphates in the soil are naturally present in organic and inorganic forms. Both forms are insoluble or slightly soluble forms of phosphate, so their availability for soil biota is very limited. This study aimed to identify the phosphate solubilizing bacteria from locally PGPR product from Temanggung, Indonesia, namely BPF 1. The method in this study was carried out by molecular identification using the 16S rRNA encoding gene which includes bacterial DNA isolation, DNA amplification using PCR, bacterial DNA sequencing and the creation of phylogenetic trees. The results of the study were obtained isolate bacteria solubilizing phosphate BPF 1 from PGPR products of local farmers of Temanggung Regency identified as the genus Bacillus, having the closest kinship with B. subtilis strain SBMP4 (NR_118383.1) with a similarity of 98.42%.

Abstract

Cardamom and Sambiloto are phytopharmaceutical plants that produce phytochemical compounds that have the potential to be used to increase immunity against COVID-19. because they contain carotenoids, phenols, anthocyanins, saponins, alkaloids and steroids. This research aims to obtain the molecular characteristics of Cardamom and Sambiloto plants from the Gunungpati area, Semarang by ITS primer, testing phenolic phytochemicals, tannins, flavonoids, saponins and alkaloids followed by molecular docking tests with the 6WX4 protein. SARS-CoV-2. Molecular characterization results show that Cardamom and Sambiloto are similar to Wurfbainia compacta MF802556.1 (100%) and Andrographis paniculate LC646073.1 (84.47%). The results of the phytochemical test screening showed that both plants contain flavonoids. Molecular docking tests were carried out with the compounds Quercetin, Avicularin, Naringenin, 5-hydroxy-7,8,2',5' tetramethoxyflavone, and Retinoic Acid. Retinoic Acid as a test ligand has the greatest potential in inhibiting the 6WX4 protein in the SARS-CoV-2 virus with a binding affinity value of -7.28 and RMSD 0.00.
