Genetic Transformation and Expression of Sucrose Phosphate Synthase Mutant in Tomato PlantÂ ABSTRACTSucrose phosphate synthase (SPS) is a key enzyme responsible for sucrose biosynthesis. In its regulation, SPS activity is modulated by an allosteric effector glucose-6-phosphate (G6P) suggested to have an ability to bind SPS N-terminus domain. To understand the role of N-terminus in regulating SPS, the SPS gene was mutated with the deletion of N-terminus domain (âˆ†N-SPS). The âˆ†N-SPS gen was transformed into tomato plants with 5% transformation efficiency. Three transgenic tomato plant 4.20, 5.5.1, and 5.10 were obtained and confirmed by PCR analysis. Transgenic tomato expression was characterized by enzymatic analysis. Result showed that the G6P allosteric regulation in transgenic âˆ†N-SPS had lost and the SPS activity increased by 2-fold compared to non-transgenic plant. This showed that N-terminus domain-deleted SPS could be actively expressed in plant.Â Keywords: enzyme, genetic transformation, N-terminus domain deletion, sucrose phosphate synthase, tomatoÂ ABSTRAKSucrose phosphate synthase (SPS) merupakan enzim kunci yang bertanggung jawab dalam sintesis sukrosa. Dalam regulasinya, aktifitas SPS dipengaruhi oleh alosterik efektor glukosa-6-fosfat (G6P) yang diduga dapat berikatan pada domain N-terminus SPS. Untuk mengetahui peran N-terminus pada regulasi SPS, dilakukan mutasi SPS dengan penghilangan domain N-terminus (âˆ†N-SPS). Gen âˆ†N-SPS diinsersi pada tanaman tomat melalui transformasi genetik dengan efisiensi transformasi 5%. Tiga tanaman transgenik tomat (event4.20; 5.5.1; dan 5.10) didapatkan dan positif terkonfirmasi melalui analisis PCR. Ekspresi mutan dikarakterisasi melalui analisis enzimatik. Hasil menunjukkan bahwa tanaman tomat transgenik âˆ†N-SPS tidak dipengaruhi regulasi alosterik G6P dan aktifitas SPS 2 kali lipat lebih tinggi daripada tanaman bukan transgenik. Ini menunjukkan bahwa SPS dengan delesi domain N-terminus dapat terekspresi aktif pada tanaman.

In Vitro Somatic Embryogenesis and Plantlet RegenerationÂ of Three Varieties of Alfalfa (Medicago sativa L.)ABSTRACTAlfalfa (Medicago sativa L.) is a valuable plant as a source of food for animal, forage, pharmaceutical, medicine, food supplement, and human consumption.Â In vitro selection technology combined with induction or spontaneous mutagenesis has been effective in altering or isolating genetic variability for desirable characters.Â Consequently, a reproducible in vitro propagation technique of that plant is mandatory. The aim of the research was to obtain information on the embryogenic callus induction, somatic embryogenesis, and plantlet regeneration of three varieties of alfalfa. The results showed that an optimum embryogenic callus induction (82%) was obtained on Murashige & Skoog (MS) basal medium containing 2 ppm 2,4-dichlorophenoxyacetic acid (2,4-D), 2 ppm kinetin and 2 ppm a-naphthaleneacetic acid (NAA). Those embryogenic calli could subsequently develop into somatic embryos, which germinated and regenerated into normal plantlets on R1 medium consisting of MS nutrients without the addition of plant growth regulator.Keywords: alfalfa, callus, embryogenic, plantlets, regenerationÂ ABSTRAKAlfalfa (Medicago sativa) adalah tanaman berharga sebagai sumber makanan untuk hewan, yaitu hijauan pakan ternak, farmasi, obat-obatan, suplemen makanan dan konsumsi manusia.

The Effect of Basal Media and NAA on the In Vitro InductionÂ of Oil Palm (Elaeis guineensisÂ Jacq.) RootABSTRACTClonal propagation of oil palm plants using tissue culture technique results in a low percentage of rooted shoots. To increase the percentage of rooted shoots that are more uniform, the root induction method is supported by the use of basic media and the addition of growth regulators 1-naphthaleneacetic acid (NAA). This study aims to analyze the effect of a combination of base media and optimum NAA concentration in inducing the roots of oil palm shoots in vitro. This research used factorial completely randomized design (RAL) consisting of 2 factors. The first factor was the type of basic media, namely MurashigeÂ and Skoog (MS) and MS Modifications (MSM) media. The second factor was the concentration of NAA, namely 0; 0.05; 0.1; and 0.2 ppm. each treatment was repeated 10 times. The results showed that the use of MSM medium was better than that of MS, and the most optimum NAA concentration was 0.05 and 0.1 ppm, in inducing oil palm roots in vitro. In addition, the combination of MSM + NAA 0.1 ppm treatment produced the most optimum result in induction of oil palm roots in vitro.Keywords: basal media; NAA; palm oil; plantlet; root inductionABSTRAKPerbanyakan klonal tanaman kelapa sawit menggunakan teknik kultur jaringan menghasilkan persentase tunas berakar yang rendah.

Influence of Biofloatation Technique through Rhizopus sp. Fermentation on the Nutritional Quality of the Floating Fish FeedABSTRACTSolid fermentation using the mold Rhizopus has been used as an alternative method to improve the physical quality of fish feed, namely stability in water and floatability. Although the fermented fish feed produced had been shown previously to have better stability in water and floatability, the effect of the fermentation on the fish feed nutrition has not yet been known. This study aimed to determine the effect of solid fermentation using the mold Rhizopus sp. on the nutrient content of the fermented feed. In addition, the effect of adding tapioca as much as 0, 1, 2, 3, and 4 g to the dry weight loss and density of the fermented feed was investigated. The results showed that the fermented feed contained higher levels of ash and protein than that before fermentation. The addition of tapioca up to 4 g had no significat effect (p>0.01) on the dry weight loss of the fermented feed, but tended to increase its density compared to those without tapioca addition.Keywords: density, fermentation, fish feed, nutrition, RhizopusÂ ABSTRAKFermentasi padat menggunakan kapang Rhizopus telah digunakan sebagai metode alternatif untuk memperbaiki kualitas fisik pakan ikan, yakni stabilitas dalam air dan daya apung. Meskipun pakan ikan fermentasi yang dihasilkan sebelumnya sudah dibuktikan memiliki stabilitas dalam air dan daya apung yang lebih baik, namun pengaruh fermentasi terhadap nutrisi pakan ikan tersebut belumlah diketahui. Penelitian ini bertujuan mengetahui pengaruh fermentasi padat menggunakan kapang Rhizopus sp. terhadap kandungan nutrisi pakan fermentasi, dan pengaruh penambahan tapioka sebanyak 0, 1, 2, 3, dan 4 g terhadap kehilangan berat kering dan mass jenis pakan hasil fermentasi. Hasilnya menunjukkan bahwa pakan fermentasi mengandung kadar abu dan protein lebih tinggi dibandingkan sebelum difermentasi. Penambahan tapioka hingga 4 g tidak berpengaruh nyata (p>0,01) pada kehilangan berat kering pakan fermentasi, namun cenderung meningkatkan massa jenis dibandingkan tanpa penambahan tapioka.Kata kunci: fermentasi, massa jenis, nutrisi, pakan ikan, Rhizopus
