Abstract

ABSTRACTThe critical period of red chili (Capsicum annuum L. var. long chili) under water stresstreatment. The research of the effect of water stress to the morphological characters of redchili was conducted to understand the critical period of vegetative stage. The experiment wasarranged based on Randomized Complete Block Design, consist of 14 water treatments with 3replications. Stressed plants were watered 500 ml each week at stress period and no stressedplants were watered 1500 ml each week. On the first weeks all samples were watered in fieldcapacity. The treatments i.e. Control plants were watered during 1-14 weeks; Plants weretreated in stress period respectively at ages 2 weeks; 2-3 weeks; 2-4 weeks; 2-5 weeks; 2-6weeks; 2-7 weeks and continued watering; Plants were watered at field capacity during 2-7weeks, 2-6 weeks; 2-5 weeks; 2-4 weeks; 2-3 weeks and 2 weeks, and continued stressperiod treatment; Plants were treated in stress period during 2-1 4 weeks. The result showedthat (i). Water stress treatments were significantly increase roots length; reduce length andweigl~t of stem; number, area and weight of leave. (ii). Red chili plants at vegetative stagewere more resistant to water stress compared with reproductive stage according to stem andleave parameters.Keywords: Critical period, water stress, Capsicum annuum L. var. long chili

Abstract

Atactodea striata (Gmelin, 1791) are inhabitants of the sandy at Village Ohoider, Kei Kecil Islands, MalukuTenggara. Sampling has been carried out on the 15th of September 1997 to October 1998 for the shell heightmeasurement. Monthly length frequency data were then analyzed using the software FiSAT II to estimatepopulation parameters such as population structure, age maximum, maximum length, growth and recruitment.Result obtained from this study is that Atactodea striata shells generally consist of four age groups, except in certainmonths were widened to five because of the occurence of old shell group. Mussels in this study reproducemultivoltine with expected life span of almost four years. The maximum length of the mussels is 19.03 mm at 95%confidence level, and the growth coefficient K = 0.37 with a growth performance index Ï? '= 1.74. Observations onhabitat sediment discovered that these shells prefer to live in the fine sand with range of fire grain of 65.96 to69.09%.Keywords:: Dynamics Population, Atactodea striata, Kei Kecil Islands, Maluku Tenggara

Abstract

ABSTRACTTomatoes (Lycopersicum esculentum Mill.) horticultural which are very good for consumption as well as industrial materials.  However, the cultivation of tomatoes still faces many obstacles, one of them is the seed.  The quality of old seeds decreases with age of seeds, so that it will affect a crop production.  This study aims to determine whether the magnetic field strength can improve tomato plant vigor.  The study was conducted using a completely randomized design (CRD) of one factor, the induction of a magnetic field consisting of 3 levels, namely 0.1 mT (M0.1), 0.2 mT (M0.2), 0.3 mT (M0,3) for 7 minutes 48 seconds. This study uses two controls;  positive control the new seed (Sn) and negative control was the old seed (So) from not being given a magnetic field treatment each experiment unit is repeated 5 times.  The parameters measured were plant height, chlorophyll content, and carbohydrate content.  The data obtained were analyzed.  If there was a difference between treatments, it was continued with the smallest difference between treatments using the Tukey's test at the 5% level.  The results of the analysis prove that the magnetic field induction of the old seed can increase seed vigor, causing plant height, chlorophyll and carbohydrate content to be the same as plants from new seeds.    Keywords: tomatoes, old seeds, strong magnetic field

Abstract

Analysis of Radiated Ratsnakes (Coelognathus radiatus, (Boie 1827) Karyotype. Radiatedratsnake is a reptile which has an economic potential an export comodyty. However, there arefew reports on genetic studies of radiated ratsnake. The aim of this research was to examinechromosome characters of the radiated ratsnake collected from Sewon, Bantul, Daerah IstimewaYogyakarta. Chromosome preparation method used was splash using blood culture. The resultsrevealed that the diploid chromosome number (2n) of radiated ratsnake was 30, classified asmetacentric (chromosome pairs number 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, dan 11), submetacentric(chromosome pairs number 12 and 13), and telocentric (chromosome pairs number 14 and 15).Therefore the karyotype formula of radiated ratsnake was 2n = 2x = 30 = 22 m + 4 sm + 4 t. Theresult showed that the shortest of short arm chromosomes was 0 ?m, the longest one was0.665 ± 0.0504 ?m, the shortest of long arm chromosomes was 0.268 ± 0.0011?m, the longestone was 0.746 ± 0.0059 ?m, the shortest of total length chromosomes was 0.27 ± 0.001 ?m, andthe longest of total length chromosomes was 1.41 ± 0.045 ?m. The R value was 5.267 ± 0.15408indicating that radiated ratsnake from Sewon, Bantul, Daerah Istimewa Yogyakarta haschromosome variation size.Keywords: Coelognathus radiatus, blood culture, chromosome character, karyotype

Abstract

 ABSTRACTThe utilization of bacterial enzymes in commercial industry, agriculture, waste treatment and health is preferred over other sources like plants and animals sources because they provide many advantages for different applications. The genus Chitinophaga which was first described as chitinolytic Myxobacteria, known as chitin destroyer or chitin eater due to their capability to hydrolyze chitin. The present study aims to isolate, characterize, identify, and assay the indigenous bacteria from Wanggameti National Park for their lytic activity againts chitin, cellulose and protein as an initial step in bio-prospecting of Sumba Island. Eleven yellow pigmented isolates were obtained from soil and decayed wood samples using ST21 and Water Agar media. They formed halo on VY/2CX medium. Physiological charazterization showed that two isolates were able to produce catalase but none of them produced urease. The phylogenetic analysis based on 16S rRNA gene sequences indicated that all isolates belong to the genus Chitinophaga that consisting of Chitinophaga filiformis, Chitinophaga ginsengisoli, Chitinophaga pinensis, and Chitinophaga sancti. They were deposited in InaCC under the name InaCC B1254 to InaCC B1264. Qualitative analysis of their lytic activity exhibited that all strains were able to lyse chitin and cellulose. The strains with the highest chitinase and cellulase activity are InaCC B1260 and InaCC B1258 strains, respectively, both of them are C. pinensis. Hereafter, C. filiformis showed the highest proteolytic activity in skim milk casein amongs all strains at 1.14±0.08. Keywords: Chitinophaga, chitinase, cellulase, protease, Sumba

Abstract

Ovarian cancer cell metastasis is induced by signaling pathway activated by the binding of type IV collagen to ?1 integrinreceptor on the surface of cancer cells and estrogen binding to estrogen receptor. However, the role of estradiol-17? andtype IV collagen on the development of ovarian cancer have not been clearly understood. Therefore, this research wasconducted to observe the differential gene expression in SKOV-3 ovarian cancer cells cultured on type IV collagen andtreated with estradiol-17?, and incubated for 12, 24 and 72 hours. Differential display RT-PCR was used to express thedifferential expression gene after treatment. cDNA fragment that expressed differentially was isolated and sequenced.Sequencing result on one of the cDNA fragment showed that PI3K is one of the gene expressed in SKOV-3 ovarian cancercell. To verify this result, cDNA was amplified using PIK3CA specific primer. The increasing level of PIK3CA is inducedby three kinds of receptor activities, those are c-erbB2 receptor bound to estradiol-17?, homodimer receptor of c-erbB2, andthe activity of integrin receptor bound to type IV collagen. The increasing level and activity of PIK3CA can also increasethe expression of c-erbB2 gene. In SKOV-3 cells cultured on type IV collagen for 72 hours, the increasing of PIK3CA andc-erbB2 expression level is very low. The conclusion is that estradiol-17? gives a more significant effect than type IVcollagen to induce the increasing expression of PIK3CA and c-erbB2 genes.Keywords: ovarian cancer, SKOV-3, type IV collagen, estradiol-17?, PIK3CA, c-erbB2
