Abstract. Abbas B, Tjolli I, Dailami M, Munarti. 2019. Phylogenetic of sago palm (Metroxylon sagu) and others monocotyledon based on mitochondrial nad2 gene markers. Biodiversitas 20: 2249-2256. Sago palm forest and sago palm semi cultivated are found in the Papua islands as well as Ambon and Seram islands. The diversity center of sago palm is found in the Papua Islands. The objectives of this study are revealed sequence DNA mitochondrial associated with nad2 genes in sago palm accessions and molecular phylogenetic of sago palm and other monocotyledon plants. Plant materials used in the studies were derived from Sago Research Center (SRC) and sequencing and other monocotyledon were retrieved from the GenBank, NCBI accessions. Young fresh leaflets were derived from the experimental field of SRC and DNA extraction by following the procedure of Plant Genomic DNA Mini Kit and then PCR performed by using nad2 primer sets. Thereafter, DNA PCR product was sequenced by Macrogen Inc., Seoul, Korea. Sequences of nad2 genes in sago palm accessions from Papua, Indonesia were registered by GenBank NCBI for further used in the future as biological authenticity from the certain location. Mitochondrial DNA sequences associated with nad2 genes in the genome of sago palm were shown no differences among sago palm accessions. Molecular phylogenetic of sago palm and others monocotyledon based on nad2 gene markers showed the sago palm and others monocotyledon incorporated into two major clades and five subclades. Sago palm, coconut, and date palm were described as close related and being in the same subclades.
Abstract. Abbas B, Tjolli I, Munarti. 2020. Genetic diversity of sago palm (Metroxylon sagu) accessions based on plastid cpDNA matK gene as DNA barcoding. Biodiversitas 21: 219-225. Metroxylon sagu Rottb is one of the plant species including in the Palmae family that deposits starch in the trunk. Sago palm was reported has high capability to produce a large amount of starch and large variation starch qualities which were mostly influenced by genetic factors. The objectives of this study are revealed sequence chloroplast DNA (cpDNA) associated with matK genes for the genetic diversity identification of sago palm accessions. Plant materials used in the studies were derived from Sago Research Center (SRC) collection. DNA extraction has adopted the procedure of Plant Genomic DNA Mini Kit. Polymerase chain reaction (PCR) was performed by using primer sets of MatK-1RKIM-f and MatK-3FKIM-r. DNA PCR product was sequenced by the 1st Base Asia, Singapore. Results of the study showed that the cpDNA sequence associated with matK genes in the genome of sago palm showed differences among accessions. Molecular diversities of sago palm accessions based on matK gene showed sago palm accessions separated into two genotypes. Genotype-1 incorporated of ten individuals of 15 accessions and genotype-2 incorporated five individuals of 15 accessions. A mutation site and deletion site occurred in the sequences of matK gene of the Genotype-2. Ten of the 15 sequences of the matK gene (belong to Genotype-1) were registered in the GenBank, NCBI as DNA barcoding and authenticity of sago palm germplasm from Papua islands, Indonesia territorials.
Sago palm is flowering and fruiting just once in their life cycle. Sago palms that grow naturally and semi cultivated were generally occurred natural pollination to form fruits and seeds, if not cut down to take the starch contained in their trunk. Sago palm pollination may occur as self-pollinated and cross-pollinated. If cross-pollinated was occurred in the pollination process, it will be varied of their progenies. This study aims to reveal the genetic variation of sago palms progenies with naturally pollinated process. The research method is to collect seeds from one parent trees that have produced ripe fruit. Fruit seeds germinated to be made and tested genetic variation using RAPD markers. Isolation of DNA is done by using the fresh young leaves. DNA amplification is done by using RAPD primers. The results showed that the progenies derived from naturally pollinated of sago palms were genetically varied based on RAPD markers and also varied based on morphological phenotypic. Variations occurred in the progenies of sago palm indicated that the sago palms were estimated cross-pollinated naturally, as a result fruits and seeds with genetically differences.
Orchidaceae has known as an attractive flower and immense species. We have found a large species of Orchidaceae grow naturally in Papua's jungle, Indonesia territorial. This study aims to reveal genetic variation and genetic relationships among endemic orchids in Papua based on RAPD markers. The study included 26 accessions of Papua's endemic orchids used for genomic DNA extraction. Genomic DNAs were extracted by using DNA extraction kit from Qiagen and genomic DNA amplification by using 10 decamer RAPD primers. DNA fragments that were amplified by Polymerase Change Reaction (PCR) were visualized and documented by using UV illumination apparatus. Genetically, endemic Orchids in Papua were described high variation. Fragments amplification by using ten RAPD primers and performed in the PCR tools resulted in 54 numbers of polymorphic fragments and no monomorphic band. The number of polymorphic bands per primer ranged from 4 to 7 with averaged 5.4 bands per assay unit. The genetic dissimilarities (GDs) among examined orchids ranged from 0.10 to 0.94 based on Nei's unbiased coefficients. Dendrogram construction showed that Papua's endemic orchid (PEO) samples different from another and separated to form group by their own at the 0.40 coefficient value and at the 0.6 coefficient value indicate that PEO sample is divided into nine groups i.e. samples at the genera level were separated into their own groups.
Mycorrhiza is ana structural and functional association between specific fungus and the roots of symbiotic relationship between mutualisme functions with a high degree of plant roots. Benefits of mycorrhiza for plant growth and development as its host is to increase the absorption of nutrient elements of soils, as biological barrier against infection of root pathogen, enhancing the resilience of crops to drought and increasing hormone boosters grows. This research aims to identify a arbuskular mycorrhiza fungi isolated from chilli plants rhizosphere in the village of Cilubang Mekar, Gunung Picung, Cikoneng, dan Kampung Baru. The results of this research show that the exploration and characterization of spores that develop on the roots of chilli in the village indicates a growing spores there is the genus Acaulopora, Gigaspora, andGlomus.type of Spore that successfully identified a species of Glomus sp 1, Glomus sp 2, Glomus sp 3.
