Abstract

ABSTRACT Sugarcane (Saccharum officinarum L.) is one of importance crop grown in marginal in Indonesia. Phosphorus (P) is critical to the growth and development of plant in the marginal land. P is stored in plant  as phytic acid (myo-inositolhexakisphosphate).  Phytic acid is hydrolyzed by the activity  of phytases to yield inositol and free phosphate. Genetic transformation of sugarcane with phytases gene holds promise to provide enough P during period of rapid cell division and growth of plant.  Plant transformation mediated by Agrobacterium tumefaciens, has become the most used method for the introduction foreign genes into plant cells and the sub sequens regeneration of transgenic plant. The selection and regeneration of embryogenic callus of transformed plant was done on MS medium containing kanamycin. The main objective of this study were: (1) To find the best kanamycin  concentration for selectable marker; (2) Insert phytase gen into  varieties of sugarcane (cv. PA 175) through Agrobacterium tumefaciens GV 2260 (pBinPI-IIEC); and (3)  To analyze of intregated transgene into genom of sugarcane using PCR  method.  Result of the experiment showed: (1) kanamycin selectable marker lethal doses for transformed sugarcane calli: 100 mg l-1;   (2)  Efficiency transformation of putative transgenic line  was cv. PA 175= 24 %; (3)  The first culture of transformed calli become 24 (Triton cv.), 18 (PSJT 94-41 cv.), and 30 (PA 175 cv.) putative plants; the second sub cullture of putative eksplant regenerate become new plant: 380 (PA 175 cv.) plants.  (4) Analyzed of integrated phytase gene was proven by appearance of 900 bp of PCR band (5) transgenic plants (cv. PA 175)  with highest activities respectively: 45 %; with medium phytase activity: 27 %, and low phytase activity: 27 % from total of sample.  Non transgenic plants, most of sample show low phytase activity respectively:  100 % , noneh show medium - hight activy of phytase.  Key words: Sugarcane, transformation, phytase,  Agrobacterium tumefaciens

Abstract

ABSTRACT Indonesia has a rich biological diversity due to its varied climatic, altitudinal variations and ecological habitats. There are two methods of conservation: in situ and ex situ onservation, both are complementary to each other. In situ methods allow conservation to occur with ongoing naturalevolutionary processes, ex situ conservation via in vitro propagation also acts as a viable alternative for increase and conservation of populations of existing bioresources in the wild and to meet the commercial requirements.  The research was aimed to determine the source of explants and consentration of activated carcoal. This research has been conducted in 4 months has been carried out during March to July 2008 in the Laboratory of Indonesia Centre for Biodiversity and Biotechnology, Nagrak Cilubang-Bogor. This research using completely randomized design arranged as a factorial with two factors, and 5 replicates. The first factor is sources of explants with two levels different (up and down of shoot). The second factor is the consentration of activated carcoal with 5 levels, namely: 0,1,2,3 g.l-1.  The results showed that up of shoot show the best growth performance; while the best medium to increase explant regeneration with 2 g.l-1 activated carcoal.Keywords: in vitro propagation, Nephentes mirabilis, activated charcoal, source of explants.
