Abstract

Leucadendron (Proteaceae) is a South African genus, the flowers of which have become a popular item in the Australian cut-flower industry. All species are dioecious. In general the female flowers are the more desirable as cut flowers. The availability of a molecular marker linked to sex determination is therefore needed both to maximize the efficiency of breeding programs and to supply markets with flowers from the preferred sex. The polymerase chain reaction-based method of suppression subtractive hybridization (SSH) combined with mirror orientation selection (MOS) were applied in an attempt to identify genome differences between male and female plants of Leucadendron discolor. Screening of 416 clones from a male-subtracted genomic DNA library and 282 clones from a female-subtracted library identified 13 candidates for male-specific genomic fragments. Sequence analyses of the 13 candidate DNA fragments showed that they were fragments of the chloroplast DNA, raising the possibility that chloroplast DNA copy number is linked to sex determination in Leucadendron. Key words: Leucadendron, sex determination, suppression subtractive hybridization (SSH)

Abstract

Grevillea (Proteaceae) is native to Australia and is known as garden plant. The flowers have high diversity colors, which range over orange, yellow, pink, red and green. It is a large genus, consisted of 357 species. This genus is economically important and there are hundreds of Grevillea hybrids with beautiful color and shape of flower.  Information of the genetic relationships of Grevillea hybrids is not available. Ten Grevillea hybrids were used in this study to evaluate the genetic relationships between hybrids and with their parents. PCR-RAPD technique was employed in this study with seven RAPD primers. The dendrogram of Grevillea hybrids was performed using Neighbor-Joining analysis based on genetic distance. The analysis revealed that ‘Moonlight’, ‘Caloundra Gem’, and Little Pink Willie’ were clustered with Grevillea banksii. The three hybrids were hybrid of G. banksii and other Grevillea species.  ‘Superb’ was closely related to ‘Robyn Gordon’ as they are hybrid of G. banksii and G. bipinnatifida.

Abstract

Bullet tuna (Auxis rochei) dominates the neritic tuna catch, especially from the purse seine fleet within the western and southern Indonesian waters. However, high catches can lead to stock depletion and lower genetic diversity due to possible inbreeding. Therefore, population genetic information is important in monitoring the sustainability of fish stocks and proposing an appropriate species-specific conservation strategy. This study aimed to analyze the genetic diversity, population structure, and kinship relationship of bullet tuna in Bali and its adjacent waters. Sampling was carried out in September 2020 at landing sites/ports representing the north, east, south, and west region, whereas at least 30 samples were acquired at each location. The result showed that the DNA concentration obtained could produce DNA bands with allele length ranged from 94-260 bp. Observed heterozygosity (Ho) was around 0.440-0.627. While the expected heterozygosity (He) was between 0.932-0.945. The genetic variation among population, within-population, and individuals was 0.36%, 41.04%, and 58.60%, respectively. The results of the analysis of genetic diversity between individuals in the population showed very high genetic diversity. The population structure of the bullet tuna landed in West Bali, East Bali, South Bali and North Bali is the same population stock. The kinship relationship indicates that the four populations are closely related genetically.

Abstract

Phyllanthus niruri L. is a medicinal plant recognized for its wide range of therapeutic benefits, particularly its anti-inflammatory properties. This research focused on assessing the impact of P. niruri leaf extract on pro-inflammatory cytokines in vitro using RAW 264.7 macrophage cells, analyze its phytochemical composition, and validate its potential anti-inflammatory mechanisms through molecular docking studies. The extract was analyzed for its phytochemical composition using LC-MS, revealing the presence of sesquiterpene glycosides, flavonoid glycosides, and tannins among the identified compounds. Cell viability tests showed that the extract was not toxic to the cells at concentrations up to 50 µg/ml. Treatment with the extract significantly reduced the levels of pro-inflammatory cytokines TNF-α and IL-1β in LPS-induced RAW 264.7 cells, with the most effective concentration being 50 µg/ml. Molecular docking studies further supported the anti-inflammatory potential of the extract by demonstrating its ability to inhibit COX-2 and TNF-alpha. These findings suggest that P. niruri leaf extract has promising anti-inflammatory properties and needs further investigation as a potential treatment for inflammatory diseases. The in silico study provided insights into the molecular interactions between the extract's compounds and inflammatory targets, supporting its anti-inflammatory mechanism of action.
