Abstract

Salinity effects on plant can often be related to mineral ion content alteration, including phosphate. Under saline conditions, phosphate levels were reported to decrease in plants. Such effects could indirectly affect intracellular phosphate levels, leading to phosphate deficiency, which in turn leads to increased activities of phosphate uptake mechanisms. This research was aimed to investigate the effects of salinity on the expression changes of phosphate transporter genes isolated from E. camaldulensis x E. globulus hybrid clones subjected to salt concentrations of  0 (control), 50, 100, and 150 mMNaCl. Fragments of genes (1164bp long and encodes 304 amino acid polypeptides) known to be involved in phosphate uptake were identified and isolated by RACE from these hybrids, encoding a Phosphate Transporter (Ecg PT). Expression studies using Northern-Blot analysis revealed that the expression of EcgPT was found to be affected by salt, suggesting a direct effect of salinity on phosphate uptake. EcgPT was expressed differently in different clones, indicating different degrees of phosphate transporter activation in order to tolerate salt stress. Molecular data are discussed in relation to measurements of ion levels in different organs of different clones and under various salt regimes during the course of the hydroponic experiment.

Abstract

Many types of soil born fungi associate mutually with high-level plant roots by forming mycorrhiza. While fruit body characterization was used previously, now molecular method wide used to identify ectomycorrhizal fungi when faces discontinuity fruit body presented on the floor and the important of identifying ectomycorrhizal fungi that lignning in particular association.Hence, the purpose of research is to identify the ectomycorrhizal fungi associated with dipterocarp species using moleculer method. Polymerase Chain Reaction (PCR) technique was conducted on DNA extract samples from root tips of dipterocarp trees and 3 (three) Shorea (S. leprosula, S. stenoptera, and S. mecistopteryx) seedlings intentionally planted under mature trees. DNA sequences were amplified using a specific primer pair of fungus and basidiomycetes ITS 1F-ITS 4B. The identity of ectomycorrhizal fungi was obtained by matching DNA sequence of the samples to Genbank database. Molecular identification resulted in 73 genotypes that belong to 13 families, i.e Thelephoraceae, Russulaceae, Clavulinaceae, Sebacinaceae, Inocyabaceae, Amanitaceae, Entolomataceae, Heliotialetaceae, Boletaceae, Cantharellales, Hymenogastraceae, Ceratobasidiceae, and Tricholomataceae. Thelephoraceae consists of 54 genotypes, Russulaceae and Sebacinaceae 13 genotypes, Clavulinaceae 6 genotypes, and the rest consist of 1-3 genotypes. Thelephoraceae is the dominant family in ectomycorrhizal jamurcommunities. Based on the results, it can be concluded that molecular method can be used to identify the real symbiont in mycorrhiza association. In addition, molecular methods can also detect the similarity of ectomycorrhizal fungi that colonizing dipterocarps, both at trees and seedlings level.

Abstract

This study aimed to determine the genetic diversity of sandalwood on seed production stand and rehabilitation stand in East Nusa Tenggara using isozyme genetic marker. The study was conducted using samples collected from three stands, i.e. Seed Production Area (APB) representing seed production stand, KHDTK rehabilitation stand and CSR rehabilitation stand representing rehabilitation stands. Samples of sandalwood juvenile leaves are taken randomly from each location. Sample materials taken were juvenile leaves collected randomly from each stand. There were 57 samples taken from APB, while each 25 samples were collected from rehabilitation stands of KHDTK and CSR. Isozymes analyses were carried out in the laboratory using three kinds of enzyme systems i.e Esterase (EST), Diaphorase (DIA) and Shikimate Dehydrogenase (SHD). The results showed that for genetic diversity within stands, the mean of polymorphic loci was 88.89%, with a mean number of alleles per locus 2.1667 and a mean of effective alleles 1.2103. The expected heterozygosity within stands (HS) was 0.1558, with the observed heterozygosity (HO) of 0.1402, while the mean index of fixation (FIS) was 0.1118. On genetic diversity among stands, DST, and GST values were 0.0090 and 0.0545 respectively, while total expected heterozygosity of the three stands (HT) was 0.1648. To anticipate sandalwood genetic diversity decline, it is essential to identify and record the remaining sandalwood populations, then conserve rare alleles either through in-situ or ex-situ conservation programs.

Abstract

Plants that have mycorrhizal symbiosis tend to be more resistant to the drought because external hyphae of mycorrhizal will expand the surface of water uptake and it can infiltrate into capillary pores so that water uptake for the host plant need will increase. This study aimed to know the response and adaptation mechanisms of mangium in facing drought stress, to investigate mycorrhizal roles in overcoming drought stress on mangium, and to select the origin of mangium seed source that is tolerant to drought stress. The study used mangium seedlings from four different seed sources and was arranged in split plot pattern of randomized block design, with three factors. The result showed that mangium root infected by mycorrhizal decreased along with increasing level of watering intervals. Mycorrhiza increased height-diameter growth and total biomass of mangium for the entire seed source. Total biomass growth of seven month mangium was significantly influenced by the origin of seed source. The highest total biomass was derived from F-1 Wonogiri (7.14 grams) and followed by Group B (6.82 grams), Group C (6.21 g) and Group A (5.84 g). Adaptation mechanisms of mangium seedlings during drought stress were keeping the water status of the plant, improving plant roots system, and thickening the leaf blades.

Abstract

Gyrinops versteegii (Gilg.) Domke is including one of superior agarwood-producing plants and naturally growing in Eastern Indonesia as Nusa Tenggara and Papua. Indonesia has been trading agarwood products both domestically and overseas which one of them is agarwood produced by G.versteegii. This study purpose was to develop an in vitro culture method for mass propagation of G. versteegii. Shoot induction conducted on MS medium supplemented with Benzyl Amino Purine (BAP) 0.7; 1.0; 1.5; and 2.0 mg/l. The shoots multiplication conducted on MS medium supplemented with the best concentration of BAP from shoot induction phase. The rooting of shoots conducted on half strength MS medium supplemented with interaction of Napthalene Acetic Acid (NAA) 0.01 mg/l with concentration of Indole-3-Butyric Acid (IBA) 1.0; 2.0; 3.0; and 4.0 mg/l. Epicotyl explant with a given concentration level of BAP 0.7 mg/l produce the highest rates number of shoots and shoot length compared to other explant respectively 4.8 shoots and 0.41 cm within 6 weeks. The best explant developments in the best medium able to promote the growth of the length and number of shoots are 0.28 shoots and 0.3 cm within 4 weeks. Explants easiest, quickest and most high sprouting ability as a factor of success in terms of multiplication is epicotyl. The combination treatment of material explant with concentration of BAP only affect to growth of shoots length. The combination treatment of NAA with concentration of IBA has no effect against root formation and growth rootlength.

Abstract

Pinus merkusii sap is one of Indonesia's superior NTFP products with high economic value. Increasing the sap productivity through the uses of geneticaly improved material of high resin yielder pinus, referred as “Pinus Bocor Getah” (PBG), is necessary. Vegetative propagation technique could used to obtain the high productivity of PBG in shorter times. This research aims to observe the rooting ability of PBG clones through a callus shoot cuttings technique. Of the 24 clones observed, 14 clones were taken from the hedge orchards and 10 clones were from selected tree in progeny test. Two experimental design used are completely randomized block designs and completely random design. Observation on the rooting ability includes parameters of the success rate of rooted, height increase, number and length of primary roots, number and length of secondary roots, root volume, root biomass and shoot and root ratio. The results showed that all tested clones showed ability to perform rooted shoot cutting, but the percentage rate of rooting varied among the clones. Amount of 71.42% clones from hedge orchard were rooted above 50% with Clone Pkp 9 and Pkp 13 as the highest percentage of rooting ( 93.75%). For the clones from progeny test, only one clone of Ppt 17 was rooted at above 50% (82.08%). The clones were significantly affected the primary root length and the number of secondary roots, especially for the clones from hedge orchard. The highest primary root length was found in Clone Pkp 3 (66.38 cm), and the highest number of secondary roots was found in Clone Pkp 14 (39). Other observed parameters were not significantly affeted by the difference of clones. The results of the study indicate that some PBG clones have the potential to be further developed massively through clonal propagation techniques.

Abstract

Ketak (Lygodium circinatum (Burm.) Sw.) is a fern plant and its growth requires other plants as a host plant for climbing of tendrils to get light. Information of vegetation association of host plant is needed, due to it is considered to have an influence on fern growth and productivity. This data and information is important to develop a strategy of ketak cultivation. This research was aimed to determine vegetation association of ketak host plant in its habitat. The study used purposive systematic sampling by survey technique based on altitude i.e. 0-249, 250-499 and 500-750 m asl. There are 10 of observation plot with dimension of 20 m x 20 m. In each plot, an analysis of vegetation association of ketak host plant to determine association between species, type of interaction and index of association between species of ketak host plant. The results showed that the vegetation association of ketak host plants in each altitude classification which had a positive and strong association are 7 pairs species in altitude of 0-249 m asl. and altitude 250 – 499 m asl., and 10 pairs species in the altitude 500 – 750 m asl.

Abstract

We combined feld observations with isoenzyme analysis to compare population demographic and its effects on genetic diversity and mating systems, among six populations of sandalwood in Gunung Sewu, Indonesia, during March to August 2015. This endangered economic-important species was originated from the southeastern parts of Indonesia, but is recently occured as new landraces in Gunung Sewu, Java island. The observed heterozygosity varied from Ho 0.184 to 0.385 in parents, and from Ho 0.083 to 0.348 in offspring levels, based on the degree of clonality and genetic base. Most of genetic variation is distributed within populations, and only 2.7% were presented among populations, that was indicated by the low DST and FST value (HT 0.30; HS 0.276; DST 2.4%; FST 7.98%). A dendrogram indicated a grouping of populations into three clusters. However, there were seemed to be no association between geographical and genetic distance. Genetic depletion occured due to (i) clonality events as result of heavy-exploitation and/or natural disturbance which induced root suckering, (ii) genetic drifts and bottleneck effects, (iii) the founder effects due to parental low diversity, and (iv) the alteration on mating systems to be more inbreeders. Some of the results confrmed a “reproductive assurance prediction” while some others were contradicting this. It seemed that genetic diversity and mating systems are not much affected by population size, but more by the parental heterozygosity and the degree of clonality. Our results emphasized the importance of populations’ genetic base or parental genetic diversity to naturally maintain the genetic and evolutionary processes under equilibrium conditions.
