Abstract

ABSTRACT Melastoma malabathricum L. is an Al-accumulating plant that grows well in acidic soils with high level of soluble aluminum in the tropics. One of the important proteins in the detoxifying Al stress is a plasma membrane H+-ATPase, a most abundant protein on the plasma membrane, encoded by PMA gene. The objective of this research was to isolate and characterize the gene encoding plasma membrane H+-ATPase from M. malabathricum L. Full length cDNA of MmPMA had been successfully isolated through a gradual isolation of the gene. The 5’ end and middle part of the MmPMA gene had been successfully isolated by PCR by using total cDNA as template and pma primers designed from some plants, while the 3’ end of Mmpma had been isolated by 3’ RACE. The parts of the gene had been successfully joined by PCR. The joining product was successfully inserted into pGEM-T Easy and the recombinant plasmid was successfully introduced into E. coli DH5α. Nucleotide sequence analysis showed that the length of MmPMA coding sequence was 2,871 bp encoding 956 amino acids with molecular weight of 105.29 kDa and a predicted pI value of 6.84. Local alignment analysis based on nucleotide of mRNA showed that MmPMA is 82% identical to pma Vitis vinifera; 81% to pma Juglans regia, pma Populus trichocarpa, pma Sesbania rostrata, and pma Prunus persica and 80% to pma Lycopersicon esculentum. Based on deduced amino acid sequence, MmPMA is 94% identical to PMA Vitis vinifera and PMA Juglans regia; 93% to PMA Populus trichocarpa; 92% to PMA Vicia faba, Lycopersicon esculentum, and Arabidopsis thaliana, AHA4. MmPMA has 10 transmembrane domains, 4 cytoplasm loops, 6 functional domains and 3 autoregulatory domains.Keywords: aluminum, cDNA, MmPMA, PCR, RACE

Abstract

Kegiatan demonstrasi produk olahan makanan berbasis sumber daya lokal dilaksanakan di Balai Kelurahan Bungkutoko, Kecamatan Nambo, Kota Kendari, dengan tujuan untuk memberdayakan ekonomi masyarakat pesisir. Dalam pelaksanaannya, mahasiswa yang didampingi oleh tim Dosen Pembimbing Lapangan (DPL) memperkenalkan dua jenis produk olahan ikan, yaitu sosis ikan dan nugget ikan. Metode yang digunakan dalam kegiatan ini adalah ceramah dan demonstrasi langsung pembuatan produk olahan ikan. Kegiatan diikuti oleh 37 peserta yang terdiri atas anggota UMKM, ibu-ibu PKK, dan tokoh masyarakat setempat. Selama pelatihan berlangsung, peserta menunjukkan antusiasme dan partisipasi aktif dalam setiap tahapan kegiatan. Melalui kegiatan ini, masyarakat memperoleh pengetahuan dan keterampilan praktis dalam mengolah hasil perikanan menjadi produk bernilai tambah yang berpotensi menjadi sumber penghasilan tambahan. Dampak nyata dari kegiatan ini terlihat pada meningkatnya motivasi peserta, khususnya ibu rumah tangga sebanyak 90% menyatakan kesiapan untuk memproduksi olahan ikan secara mandiri dari rumah, sehingga mendukung upaya penguatan ekonomi keluarga dan pemberdayaan masyarakat pesisir secara berkelanjutan.

Abstract

Melastoma malabathricum L. grows well in acid soil with high level of soluble aluminum. One of the important proteins in the detoxifying acid and aluminum stress is a plasma membrane H+  -ATPase protein encoded by PMA gene. The objective of this research was to isolate and clone the cDNA fragment of MmPMA encoding plasma membrane H+ -ATPase from M. malabathricum L. By reverse transcription, total cDNA had been synthesized from the total RNA as template. The fragment of MmPMA  cDNA  had been successfully isolated by PCR by using total cDNA  as  template and PMA primer designed from conserved region for corresponding gene. This fragment had been successfully inserted into pGEM-T Easy and the recombinant plasmid was successfully introduced into E. coli DH5". Nucleotide sequence analysis showed that the length of MmPMA fragment is 806 bp encoding 268 amino acids. Local alignment analysis based on nucleotide of mRNA showed that MmPMA fragment was 81% identical to part of PMA of Sesbania rostrata, Juglans regia, and Prunus persica. Based on deduced amino acid sequence, MmPMA was 94% identical to part of PMA of Juglans regia; 93% to PMA of S. rostrata, and Arabidopsis thaliana. MmPMA fragment has phosphorylation intermediate domain (DKTGT) and ATP binding domain (KGAP, DPPR, MITGD, and GDGVN).   Keywords: isolation, Melastoma malabathricum L., MmPMA fragment, sequencing
