Abstract

Asam laktat diketahui merupakan molekul dengan manfaat positif untuk manusia. Molekul tersebut dapat diproduksi oleh bakteri asam laktat. Produksi asam laktat seringkali terganggu karena beberapa spesies bakteri perlu penyesuaian khusus pada substrat, sehingga salah satu solusinya adalah kloning gen atau over-expression enzim L-LDH pada bakteri kompeten. Salah satu langkah prosedur tersebut adalah isolasi gen. Desain primer dilakukan menggunakan aplikasi Benchling pada subjek genom Streptococcus pluranimalium TH11417 dan seluruh primer diujikan secara in-silico menggunakan aplikasi UGENE dan in-vitro menggunakan metode Polymerase Chain Reaction (PCR). Empat pasang primer dihasilkan dengan rincian LSPai 1178, LSPbi 993, LSPad 765, dan LSPbd 846. Primer berhasil menempel dan menghasilkan amplikon yang sesuai pada uji in-silico menggunakan templat genom S. pluranimalium TH11417, namun hanya LSPai 1178 dan LSPad 765 yang dapat menempel pada templat genom S. pluranimalium 14A0014. Primer tidak dapat menempel pada uji in-vitro dikarenakan kontaminasi isolat bakteri templat DNA. Kontaminasi dikonfirmasi melalui analisis sekuen 16s rRNA dan didapatkan bahwa amplikon 16s rRNA isolat bakteri uji sesuai dengan sekuen 16s rRNA Bacillus cereus. Sekuensing basa amplikon uji in-vitro primer LSPai 1178 menunjukkan bahwa amplikon bukan merupakan bagian dari sekuen target.

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

Abstract

This study aims to identify a lactic acid bacteria (BAL) isolated from native chicken (Gallus gallus domesticus) intestinum (B21) based on 16S rRNA gene sequence and also to confirm primers for PCR-based D-Lactate dehydrogenase (D-LDH) gene isolation. The genomic DNA of B21 was isolated then amplified using 16S rRNA. The PCR product then sequenced and aligned. The sequencing was done in 1st Base Pte. Malaysia. The sequence then aligned using the Basic Local Alignment Search Tool (BLAST) in NCBI to know the similar genome species. Isolation D-LDH gene was done through PCR using 5 primers (idb 0101, idb 1147, idb 0813, idb 1010, and idb 2021) of B21 and also J15 isolate genome. The PCR product were then sequenced and aligned with the D-LDH gene sequences in NCBI. The results of molecular identification based on 16S rRNA markers showed that B21 has 99.45% similarity to Bacillus proteolyticus. Amplification of the LDH gene with idb 1010 primer on J15 isolate yielded 4 fragments (i.e. 650, 1400, 1500, and 1700bp). The results of phylogenetic tests showed that the 1700bp fragment has a high similarity to the D-LDH gene in Myobacterium tuberculosis species with a bootstrap value of 84%. While other size fragments cannot be trusted to have similarity to LDH sequence because they have not reached the minimum bootstrap value that meets the qualifications.

Abstract

The purpose of this study is to determine the effect of the addition of BAP and the position of nodus on the formation of axillary shoots and to know the optimum concentration of BAP for the induction of Dendrobium Red Emperor 'Prince' axial shoots. The research design used is a Complete Factorial Randomized Design consisting of one treatment, namely: concentration of growing regulatory substances (ZPT) BAP (0ppm, 1 ppm, 2 ppm, and 3 pmm), each treatment repeated 5 times. The explant of the nodus were taken from plants produced by previous in vitro culture having 5 nodi. The basic medium used is New Phalaenopsis (NP) + Coconut Water + 1 ppm 2.4-D). The growth of axillary bud growth is measured based on the time of the bud emergence, growth of crown, and that of root. Data obtained were then analyzed using ANOVA. If there was a significant difference, the analysis was continued with a test of DMRT with a significant level of 5%. The results showed the addition of concentrations of 1 ppm and 2 ppm BAP influenced the time of the bud emergence, growth of crown, and that of root. The optimum concentration of BAP to induce the orchid axillary shoots is 2 ppm.

Abstract

Penelitian ini bertujuan untuk mencari kondisi yang tepat dalam percepatan pembungaan tanaman Phalaenopsis amabilis transgenik yang telah disisipi gen penentu waktu pembungaan Ubipro::PaFT. Metode penelitian ini menggunakan tanaman transgenik pembawa gen Ubipro::PaFT umur 18 bulan setelah penanaman. Tanaman ditumbuhkan pada inkubator dengan pencahayaan menggunakan lampu LED putih dan kombinasi LED putih biru, dengan fotoperiodisitas 8 jam terang 16 jam gelap, suhu 25ºC pada fase terang dan 20ºC pada fase gelap selama 20 minggu. Setelah 20 minggu pertumbuhan tanaman, dilakukan analisis profil protein dengan metode SDS-PAGE untuk mengetahui protein yang diproduksi pada setiap fase pertumbuhan yang diamati.Hasil penelitian menunjukkan kombinasi cahaya LED putih dan biru meningkatkan pembentukan daun sebesar 60%, panjang daun 70,58%, tetapi belum diperoleh kemunculan infloresen. Analisis profil protein menunjukkan terbentuknya protein dengan ukuran 108,57; 71,30; 56,16; 40,85; 26,79; 13,27; dan 13,12 kilodalton pada tanaman transgenik, tetapi tidak terdeteksi protein dengan ukuran 19,65 kDa yang sesuai dengan berat molekul protein PaFT, sementara protein dengan ukuran sekitar 56,16 kDa sesuai dengan berat molekul protein POH1(Phalaenopsis Orchid Homeobox1). Hal ini menunjukkan bahwa gen vegetatif POH1 mampu menghambat aktivasi gen PaFT pada tanaman P. amabilis transgenik umur 20 minggu, sehingga tanaman masih dalam fase juvenil dan belum mampu diinduksi untuk berbunga.
