Abstract

Vanda is a monopodial epiphyte orchid that spreads throughout Asia and Southeast Asia reaching 70 species. Indonesia itself has its own endemic Vanda orchid such as Vanda tricolor and Vanda limbata. A hybrid of V. tricolor and V. limbata is predicted to form a new specific character in the flower and leaf. The purpose of this study was to determine the morphological and molecular differences between V. tricolor, V. limbata, and Vanda hybrids resulting from crosses between that two orchids, by analysing the morphological characteristics of the roots, leaves, flowers and the structure of the Vanda Orchid Homeobox1 (VOH1) shoot‐forming gene isolated from V. tricolor, V. limbata, and their hybrids. The morphological analysis was conducted using RHS colour chart, size measurement of plants, and the transversal preparation of the leaf. Molecular analysis was performed by PCR using Dendrobium Orchid Homeobox 1 (DOH1) primers, followed by sequencing and bioinformatic analysis. Morphologically, the flower’s colour of the hybrid is most similar to V. limbata but the flower’s patterns are more similar to V. tricolor meanwhile the leaf colour of the hybrid is brighter than the both parents. The slides illustrate the sclerenchyma tissue is made up of strongly thickened walls containing lignin indicates the presence of homeobox DOH1 gene homolog, namely VOH1. The molecular result displayed by the phylogenetic tree of the VOH1 indicates that the hybrid has more similarities with V. limbata.

Abstract

Coffea arabica L. is a species of coffee that contribute for more than seventy percent of world coffee production. Various attempts have been made to obtain large quantities of planting material through propagation in vitro somatic embryogenesis technology. The objective of this experiment was to evaluate the effect of different plant growth regulators (PGRs) on callus induction (indirect somatic embryogenesis) in AS2K clone of Arabica coffee. Mother plants of Arabica coffee were established in coffee experimental field of Indonesian Coffee and Cocoa Research Institute at Andung Sari, Bondowoso, East Java, Indonesia (-7Ëš55'' ' S, 113Ëš41'' ' E) at an altitude of 1380,1 m dpl. Leaf explants were cultured on a half-strength Murashige and Skoog (MS) medium supplemented with various concentration (1.0, 2.0, 3.0 mg/L) of 2,4-D and (1.0, 2.0, 3.0 mg/L) thidiazuron in combination with 1.0 mg/L BAP. All the experiments were organized in completely random design (CDR) and repeated three times, each using minimum seven replicates (a total of 21 explants per treatment). The morphologycal and histological analysis of the different types of callus were observed. The percentage of callus formation was recorded every two weeks until eight weeks. The highest percentage of callus formation (almost 60%) was in medium containing 1 mg/L 2,4-D dan 1 mg/L BAP. Morphological and histological studies prove that the callus has a friable and embryogenic texture and begins to develop various stages of somatic embryo formation, starting with the globular, heart, torpedo and cotyledonary phases.

Abstract

Phalaenopsis amabilis (L.) Blume adalah tanaman hias “Puspa Pesona Indonesia” yang dapat ditingkatkan kualitasnya dengan teknik rekayasa genetika. Transformasi genetik dengan perantara Agrobacterium tumefaciens dan CRISPR/Cas9 digunakan dalam penelitian ini untuk pengeditan genom secara lebih spesifik dan presisi pada target sekuen gen PHYTOENE DESATURASE3 (PDS3) yaitu gen yang berperan penting pada biosintesis kloroplas. Dalam penelitian ini digunakan tanaman transforman umur 12 bulan yang ditumbuhkan dari protokorm yang telah diintegrasi dengan T-DNA pembawa konstruksi UBI::Cas9::U3::PDS3/plasmid pRGEB32. Pembuktian tanaman transforman tersebut masih mengandung konstruksi T-DNA tersebut perlu dilakukan, yaitu dengan karakterisasi secara genotipe dan fenotipe. Tujuan penelitian ini adalah untuk mengkarakterisasi P. amabilis transforman pembawa T-DNA dengan konstruksi UBI::Cas9::U3::PDS3 secara genotip dan fenotip dibandingkan dengan P. amabilis non-transforman. Karakterisasi genotipe dilakukan dengan mendeteksi integrasi T-DNA pembawa konstruksi UBI::Cas9::U3::PDS3 pada genom anggrek P. amabilis menggunakan beberapa primer yaitu HPT, Cas9, PDS3 dan trnL-F (primer kontrol internal). Analisis karakter fenotipe dilakukan dengan pengamatan morfologi dan analisis kadar klorofil menggunakan metode spektrofotometri. Hasil penelitian menunjukkan bahwa genom anggrek P. amabilis transforman pembawa konstruksi UBI::Cas9::U3::PDS3 umur 12 bulan dapat teramplifikasi oleh semua primer. Analisis fenotipe P. amabilis transforman menunjukkan adanya perubahan warna tanaman dari hijau menjadi albino dengan kadar klorofil lebih rendah jika dibandingkan dengan P. amabilis non-transforman. Hal ini menunjukkan bahwa teknologi CRISPR/Cas9 dapat digunakan untuk mengedit genom tanaman anggrek. Kata kunci: Anggrek, CRISPR/Cas9, klorofil, Phalaenopsis amabilis (L.)

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.

Abstract

Vanda tricolor Lindl. var. suavis is an Indonesian wild orchid which is now extremely rare in nature due to its habitat destruction. Development of an appropriate method for improving Vanda orchid through genetic modification could be valuable for horticulture and, indirectly, also for conservation. In this research, a method of Agrobacterium-mediated transformation of two V. tricolor obtained from Salak Mount, West Java and Merapi Mount, Yogyakarta in Indonesia protocorms was improved using acetosyringone (AS). Concentrations of 0 and 25 ppm AS were used in transformation of pG35S binary vector containing kanamycin resistance geneinto V. tricolor protocorms. The result showed that 25 ppm AS was required on inoculation with Agrobacterium solution, without AS on cocultivation. Five weeks after treatment on the 300 ppm kanamicyn containing medium, green protocorms were obtained, that was 11.01% for V. tricolor from Salak Mount with pre-culture treatment prior to inoculation, 9.39% for V. tricolor from Merapi Mount with pre-culture treatment prior to inoculation, and 1.37% for V. tricolor from Merapi Mount without pre-culture treatment prior to inoculation. The best condition to set high efficiency of transformation is pre-culture protocorms prior inoculation, soaking protocorm on 25 ppm AS for 30 minutes, then co-cultivate its on AS-free callus induction medium.

Abstract

D. spectabile is an orchid species endemic to Papua, which has the characteristic of sepals, petals, and a curly labellum, which is very attractive, so it needs to be preserved. Propagation of this plant with in vitro culture techniques promises plant propagation in large quantities and uniformly in a short time. In plants, the HOMEOBOX gene is recognized as a key regulator of gene transcription, playing a crucial role in plant organogenesis, particularly in the shoot apical meristem. This study aims to identify the optimal in vitro culture media for D. spectabile and to conduct molecular analysis of the HOMEOBOX gene. The methods used are: subculture, amplification, motif location analysis, physicochemical characterization, phylogenetic construction, and 2D protein sequence modeling. The results of the study showed that the subculture of D. spectabile on KC+IAA 20 µM media (20.67±1.76) significantly increased shoot growth. PCR with POH1 primer successfully amplified a 700 bp HOMEOBOX fragment containing 2 motifs: ELK, involved in protein-to-protein interactions, and Homeobox-KN, a transcriptional regulator. Phylogenetic analysis showed a close evolutionary relationship between D. spectabile and D. catenatum. Further studies are needed to obtain the complete sequence for functional validation in D. spectabile.
