Abstract

Artemisia cina is a medicinal plant species producing bioactive compounds which are potential a antitumor, antifungal and antibacterial. The aim of this study was to analyze the stability of chromosome number in root cultures of A. cina. Transformed root culture was established by infection of leaves of A. cina with Agrobacterium rhizogenes strains 07-20001, ATCC 15834, A4; and Agrobacterium tumefaciens strain R1000. Roots isolated from glasshouse plants, plantlets grown in solid and liquid MS medium were utilized for investigation of chromosome examination of untransformed roots. Chromosome examination was conducted by squashing method and chromosome numbers were calculated under microscope. The results showed that both untransformed and transformed root had in lability in the chromosome number, but had the modal number of chromosome x=8 with the diploid number of 2n =4x = 32. Roots isolated from glasshouse plants of A. cina had 53.7~ of cell with the diploid numbers of 2n = 3 and 46.3% of cells had chromosome numbers ranged from 2n = 12 to 2n = 64. Untransformed roots isolated from plantlets cultured in solid medw had only 36.1% or cells with chromo orne number of 20 = 32, and untransformed roots grown in liquid medium had 49.4% of cells with 2n =32. The chromosome numbers of A. cina transformed roots was affected by trains of Agrobacterium. Root transformed with the bacterium Strain 07-20001 showed the highest in normal chromosome number of 2n = 32 (62.4%) followed by roots transformed with strains ATCC 15834 (61.9%). R1000 (43.6%) and A4 (43.0%). The range of the chromosome number of untransformed roots was from 2n=17 to  2n=64 whilst that of transformed roots was from 2n=11 to 2n=66.

Abstract

The protocol of micropropagation of Tetramolopium klossii (Moore) Mattfeld through adventitious shoot proliferation was established. This is the first report of T. klossii tissue culture. Seeds were surface-sterilized by dipping them in 10% of ethanol for 1 min followed by soaking in 1% of sodium hypochlorite for 10 min. The sterile seeds were germinated on MS medium solidified with 8 g/l of agar, supplemented with 20 g/l of sucrose. Two-month old seedlings formed some shoot clumps on MS solid medium without addition of any plant growth regulators. Small clumps containing 4-6 adventitious shoots were used for shoot proliferation on MS solid medium containing 0; 0.1; 0.5; 1.0 and 2.0 mg/l of BAP (benzylaminopurine) or kinetin. The results showed that medium MS without cytokinins (control treatment), and the addition of 0.1 or 0.5 mg/l of BAP was more effective for shoot proliferation compared to the medium with addition of BAP at higher concentration and the addition of kinetin. In further subcultures, multiple shoots grown on MS medium without cytokinins was more vigorous than that of shoots grown on other media, so that the shoots were ready for rooting. Medium containing 0.5 mg/l of BAP was the best for maintaining multiple shoot formation. Shoots formed roots on MS medium containing half strength of macro nutrients.

Abstract

Exploitation on plant population may put the endemic plants into an endangered state, hence, these plants will need to be conserved. In order to pursue conservation on endemic plants, we conducted in vitro seed germination and shoot multiplication of seven alpine and sub-alpine species endemic to Mount (Mt.) Jaya, in Papua, Indonesia, i.e. Tetramolopium klossii, Deschampsia klossii, Papuacalia cartenszensis, Epilobium hooglandii, Gaultheria novoguinensis, Rhododendron correoides, and Rhododendron culminicolum. These species are categorized as slow-growth plants found in higher altitude (over 3700 m above sea level) and low temperature of Mt. Jaya. Seeds were surface-sterilized using Na-hypochloride and germinated aseptically on Murashige and Skoog (MS) medium. Dytikinin benzyl adenine (BA) was used for shoot multiplication. Seedling cultures were maintained in a controlled environment with continuous low light intensity (800 lux) and at temperature 26-27oC. Results showed that most species had more than 80% of germination rate on MS medium after a week in culture. BA was required to enhance shoots multiplication. Woody Plant (WP) (Lloyd & McCown, 1981) medium gave better shoot multiplication for R. culminicolum.
