This study aim to compare more detailed between M. tuberculata and S. punctata based on their morphology, ontogeny and type of reproduction. Ontogeny studies of these two species show that M. tuberculata produces juveniles in embryonic shell form during their reproduction. This embryonic shell is nourished and developed in the subhaemocoelic brood-pouch organ as evidenced by being found in the size range 0.12–5.95 mm. One individu M. tuberculata can produce 1–66 embryonic shells. Meanwhile, in subhaemocoelic brood-pouch of S. punctata only the unshell embryo was seen and embryonic shell was not found. The difference of reproduction system determines the reproductive strategy in both species. M. tuberculata conduct euviviparity reproduction whereas S. punctata is ovoviviparous that releases juveniles in free-swimming veliger form.","PeriodicalId":280065,"journal":{"name":"BERITA BIOLOGI","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133006925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample was subsequently isolated using hot water and 1 M NaOH to obtain water and alkali soluble of crude polysaccharides. The antioxidant activity was evaluated using β-caroten-linoleat assay. The results showed that the alkali soluble of crude polysaccharides had the highest antioxidant activity (85.82%) at 350 μg/ml. The water and alkali soluble of crude polysaccharides from A.auricula were evaluated for their antibacterial activity using disc diffusion method. The alkali soluble of crude polysaccharides was found to have the highest antibacterial activity at 100 mg/ml against Staphylococcus aureus InaCC B4 and Escherichia coli InaCC B5 with clear zone values of 3.18 mm and 5.10 mm, respectively. The findings indicated that the alkali soluble of crude polysaccharides from A. auricula could potentially be used in part of well-balanced diets and could be considered as a potential source of natural antioxidant and antibacterial products.

The morphological characters of introduced soybean accessions contributed to support the result of molecular characterization. The introduced soybean accessions used in this study were diverse based on morphological and molecular characters. Based on principle component analysis, the flower color, pod color, and growth habit contributed most of the total genetic diversity. All introduced accessions were overlap into four quadrants based on principal coordinate analysis. All microsatellite primers showed polymorphism on total accession observed. High allele variation (9–27 alleles) was observed among tested accessions, with an average allele number and Polymorphic Information Content (PIC) value of 20.7 and 0.95 (0.92–0.97), respectively. All microsatellite markers showed PIC value >0.7 indicating that these markers were suitable for soybean diversity studies with high differentiation and with the average value of genetic diversity of 0.95. The phylogenetic analysis revealed that 45 soybean accessions could be divided into two major groups. Soybean accessions belonging to the same area did not always occupy the same group.

Development of Inpari 30 rice varieties tolerant to submergence to drought tolerant to have a broader spectrum of tolerance through marker-assisted backcrossing methods with the gene pyramid approach. The development of new variety using Inpari 30 as the background is one of the applications of pyramiding gene in Indonesia. Combining conventional breeding with molecular markers and phenotypic selection (drought and submergence) is expected to produce rice lines tolerant to drought and submergence with stabil yields and accelerate the homozygosity of the genome in the third generation.
