Abstract

Naturally occurring CD4+CD25+ regulatory T (Treg) cells, a component of the innate immune response which play a key role in the maintenance of self-tolerance, have become the focus of numerous studies over the last decade. These cells have the potential to be exploited to treat autoimmune disease. These cells inhibit the immune response in an antigen-nonspecific manner by interacting with other T cells. These T cell populations actively control the properties of other immune cells by suppressing their functional activity to prevent autoimmunity but also influence the immune response to allergens as well as against tumor cells and pathogens. In this experiment we showed that induced regulatory T cells have a protective effect on mice model of rheumatoid arthritis (RA). RA mice which were injected intraperitoneally with Andrographis paniculata substrate or injected with induced regulatory T cells showed the effects of recovery. We further showed that the generation of leukocyte including B cells can be promoted by the administration of A. paniculata substrate. Tissue damage from free radicals that arise due to imperfect metabolism can be prevented by such treatment in RA model mice. Recovery effects occurred in RA model mice involves the increasing number of CD4+CD25+ regulatory T cells.

Abstract

Dandelion (Taraxacum officinale Weber ex F.H. Wigg) is a medicinal plant species, reported to have some active compounds useful as anti-cancer, anti-inflammatory, antioxidants, and diuretics. Study on in vitro secondary metabolic production and tissue culture of these plants has been reported. This research was aimed to investigate plant regeneration from leaf blade, petiole and root as explants grown in selected media. Three different type of explants were cultured in MS solid medium supplemented with BAP (0, 0.5, and 1.0 mg/l) combined with NAA (0, 0.5, 1.0, and 2.0 mg/l) to select the best medium for spontaneous regeneration. Explants were grown for 6 weeks, the viability of explants, and formation of callus, shoots as well as roots were recorded. The results showed BAP at 1 mg/l combined with at 0.5 mg/l of NAA was suitable for shoot formation, whereas NAA alone was suitable for root formation from leaf blade and petiole. Root was the best explant for shoot regeneration, callus was grown at the first two weeks, and multiple shoots were grown after 3 weeks. No roots were found from root explant. The best medium for multiple shoot regeneration was MS containing 1 mg/l BAP without or with addition of 0.5 mg/l NAA.

Abstract

The aim of this research was to compare the reduction effect of sucrose or table sugar concentration on growth characteristics of red ginger cultured in MS liquid medium. Shoots of red ginger was cultured on MS liquid medium without addition of plant growth regulators, supplemented with 5, 10, and 20 g/l of sucrose or table sugar for 8 weeks. Resulted plantlets were acclimatized in a greenhouse to investigate their growth and survival rate. Numbers of stomata, chlorophyll concentration as well as cross section of leaves from plantlets grown in vitro were compared to those of transplants grown in the greenhouse. The results showed that the use of table sugar at concentration of 20 g/l gave the best growth of red ginger. Meanwhile, the reduction of table sugar from 20 to 10 g/l reduced growth and survival rate of in vitro shoots as well as that of transplants in the greenhouse. Only few shoots formed roots when they were grown on the medium containing 5 g/l of table sugar, and transplants failed to grow in the greenhouse. It found that the chlorophyll content of in vitro plantlets was lower than those of transplants grown in the glasshouse. However, the number of stomata of the in vitro plantlets was higher than that of transplants grown in the glasshouse. There was no anatomical abnormalities found on the cross section of leaves between in vitro plantlets and transplants grown in the greenhouse. The replacement of sucrose with table sugar may reduce the production cost of plantlets.

Abstract

The studies of rice genes through functional genomics are greatly facilitated by the availability of the complete genome sequences, including the complete physical map of the japonica rice cv. nipponbare. Using the Ac and Ds transposon, that are capable of transposition in various heterologous plants including the monocotyledon rice, combined with the enhancer element for generating activation taged lines, it is possible to discover and isolate functional genes involved in various important agronomical traits; such as those involved in abiotic stress tolerance (drought, high salt) and biotic stresses diseases and pests. We have developed 1,785 first (T0) generation of mutant nipponbare rice by transposons Ac/Ds insertions containing activation-tag, generated by transformation using Agrobacterium-mediated method. Currently, we have generated approximately 1,000 stable lines with transposon Ds and activation-tag insertion ready for screening. Efficient screening methods for mutant Nipponbare rice lines have been established for agronomically important mutant traits. Among the new phenotypes related to important agronomical traits observed were drought and salt tolerant or sensitive, stunted and robust growth, variable root penetration and other interesting traits such as reduced tillering, rolled leaf and thin tiller.

Abstract

Rice stem borer (Scirpophaga sp.) is considered as one of the primary pests causing yield decrease in Indonesia. Genetic engineering is considered as one of the most effective way to improve the resistance of rice plants to yellow stem borer since no resistance gene has been found in rice and its wild relatives. A double T-DNA binary vector p2TDNAcryIAb wich carry two independent T-DNA was used to transform Indonesian elite rice cv Ciherang using Agrobacterium-mediated transformation to generate transgenic rice that free from selectable marker genes. One T-DNA containing a selectable marker hygromycin phosphotransferase (hpt) gene and the other carrying the cry1Ab gene. As many as 37 putative transgenic plants from 14 embryos were generated. PCR analysis demonstrated that 22 out of 37 putative transgenic rice contain cry1Ab gene. All Ciherang rice carrying the cry1Ab gene expressing Cry1Ab protein as shown by the immunostrip assay. Further work will be carried out to determine the transgenes copy number, to select marker free transgenic rice, and to evaluate the resistance of transgenic rice against neonates larvae of yellow stem borer.
