Metabolite Markers

Background: Sago palm is an important agricultural starch-producing crop in Malaysia. The trunk of sago palm is responsible for the production of the starch reaching maturity for harvesting after ten years. However, there are sago palms that failed to develop its trunk after 17 years being planted. This is known as a stressed “non-trunking” sago palm, which eliminates the economic value of the palms. Objective: The study was initiated to compare the differences in metabolite expression between trunking and non-trunking sago palm and secondly to determine the potential metabolite-makers that are related to differential phenotypes of sago palms. Method: Metabolites were extracted using various solvents and analysed using NMR spectroscopy and GC-MS spectrometry. Data obtained were subjected to principal component analysis. Results: The study determined that differential metabolites expression were detected in the leaf extracts of normal trunking sago palm compared to the non-trunking palms. Metabolite groups which are differently expressed between trunking and non-trunking sago palm are oils and waxes, haloalkanes, sulfite esters, phosphonates, phosphoric acid, thiophene ester, terpenes and tocopherols. GC-MS analysis of Jones & Kinghorn extraction method determined two sets of metabolite markers which explains the differences in metabolites expression of trunking and non-trunking sago palm in ethyl acetate and methanol extract of 89.55% comprising sulfurous ester compounds and 87.04% comprising sulfurous ester, sulfurous acid and cyclohexylmethyl hexyl ester respectively. Conclusion: Two sets of metabolite markers were expressed in the trunking and non-trunking sago palm. These metabolites can potentially be used as markers for identifying normal and stressed plants.

Tanaman sagu (Metroxylon sagu Rottb.) memiliki potensi yang besar sebagai sumber pangan, energi dan bahan baku industri. Kultur jaringan tanaman sagu telah dilakukan di Balai Pengkajian Bioteknologi BPPT dalam rangka perbanyakan genotipe atau aksesi unggul secara massal. Namun demikian, kendala utama yang dihadapi pada perbanyakan in vitro tanaman sagu adalah sulitnya pembentukan akar. Penelitian ini bertujuan untuk mendapatkan kombinasi hormon yang tepat dalam menginduksi perakaran tanaman sagu in vitro. Tunas anakan muda (15-20 cm) yang diperoleh dari daerah Rangkasbitung, Provinsi Banten digunakan sebagai eksplan. Dalam penelitian ini perakaran in vitro diinduksi dengan berbagai perlakuan jenis dan konsentrasi hormon auksin, konsentrasi medium dan jenis agar. Sebagai medium dasar digunakan medium Gamborg. Hasil penelitian menunjukkan bahwa konsentrasi IBA dan NAA yang terbaik adalah pada taraf 35 ppm. Selanjutnya Gelrite memberikan respon yang positif dengan munculnya perakaran pada pangkal eksplan.Kata Kunci: Induksi perakaran,  jenis agar, kultur in vitro, auksin, sagu ABSTRACTSago palm (Metroxylon sagu Rottb) has huge potential as food, energy and industrial bioresources. In vitro culture of sago palm was performed in Biotech Center, BPPT in order to obtain a large-scale of mass clonal propagation of superior genotypes. Nevertheless, the main obstacle for the sago palm in vitro propagation was rooting formation. The purpose of our study was to obtain the best hormones combination for root induction on sago palm shoots in vitro. The young suckers (15-20 cm) obtained from Rangkasbitung area, Banten Province, were used as explants. In our study, in vitro rooting was induced by different types and concentrations of auxin, medium strength and solidifying agents. The shoots were cultured on Gamborg media. The result showed that the best level of both hormones IBA and NAA for root induction was 35 ppm. Moreover the solidifying agent of Gelrite gave positive response by stimulating root at the basal-end.Keywords: Rooting induction, solidifying agent, in vitro cultures, auxin, sago palm
