Abstract

The effect of introducing a supplementary ipt-gene into the genome of Nicotiana tabacum L. cv. Petit Havana SR1 is studied on the morphological plant development. The ipt-gene, accounting for the biosynthesis of cytokinins, was coupled to the heat-inducible hsp70- promoter from Drosophila melanogaster. Besides the influence of the hormonal changes involved, the effects of the experimental conditions are examined, namely the in vitro growth conditions for selecting transformed plants and the heat treatment to induce ipt-gene expression

Abstract

Tanaman padi Bt Produk Rekayasa Genetik (PRG) memiliki sifat ketahanan terhadap hama penggerek batang kuning, hasil pengembangan Puslit Bioteknologi LIPI. Berbeda dengan tanaman konvensional, tanaman PRG harus memperoleh sertifikat keamanan hayati dan keamanan pangan sebelum dilepas dan dimanfaatkan oleh masyarakat. Kajian keberlanjutan PRG berdasarkan indikasi pembangunan berkelanjutan telah dilakukan menggunakan metode expert survey dan pemilihan responden dari kalangan pakar di wilayah Jawa Barat dan Jawa Timur. Tujuan penelitian adalah mengetahui keberlanjutan tanaman Padi Bt PRG berdasarkan atribut-atribut yang menyusun dimensi ekologi, ekonomi, sosial, teknologi serta hukum kelembagaan. Analisis data yang digunakan adalah Multi Dimensional Scaling (MDS) yang hasilnya dinyatakan dalam bentuk indeks keberlanjutan terhadap setiap dimensi yang dikaji. Hasil kajian terhadap multidimensi keberlanjutan tergolong pada kriteria cukup berkelanjutan dengan nilai 58,99%, kecuali untuk dimensi teknologi dengan nilai 46,71% yang tergolong kurang berkelanjutan. Nilai keberlanjutan untuk dimensi lingkungan 73,02%, dimensi ekonomi 69,30%, dimensi sosial 51,22% dan dimensi hukum kelembagaan 54,74%. Diperoleh sepuluh faktor pengungkit (leverage factor) yang dapat mempengaruhi peningkatan indeks keberlanjutan yaitu dari dimensi ekologi (Kemungkinan terjadinya perpindahan (crossing) material genetik dari tanaman PRG ke tanaman non-PRG), dimensi ekonomi (Ketergantungan petani pada tanaman PRG, Harga beli benih PRG yang terjangkau), dimensi sosial (persepsi dan penerimaan masyarakat, keterlibatan publik dalam pengambilan keputusan), dimensi teknologi (jumlah tanaman PRG hasil litbang sendiri, kemampuan SDM melakukan riset dan pengujian tanaman PRG) serta dimensi hukum kelembagaan (implementasi peraturan dan undang-undang, labeling terhadap PRG).

29. Effects of high-LET particles /A-40/ on the brain of Drosophila melanogaster

Abstract

To investigate the effects of galactic heavy particles on nervous tissue, Drosophila melanogaster flies were exposed to A-40 from the Super-HILAC accelerator at the Lawrence Berkeley Laboratory. The energy of the particles reaching the Drosophila neurons was 4.8 MeV/nucleon, and the fluence ranged from 60,000 to 80 million particles/sq cm. Thirty-five days after irradiation at the higher fluences, extensive tissue fragmentation and cysts were found. At fluences as low as one hit/two cell bodies (about 5 million) and one hit/90 cell bodies (about 90,000 particles/sq cm or 21 rad average dose) swelling of neuronal cytoplasm and focally fragmented membranes were noted; at fluences ranging from one hit/six to one hit/135 cell bodies, there was frequently a marked increase in glial lamellae around nerve-cell processes, which often had degenerative features. These findings support the view that single hits by heavy particles may injure nervous tissue.

Abstract

The Agrobacterium tumefaciens leaf disc infection method was used to introduce several cointegrates containing the T-DNA ipt-gene (gene 4) into tobacco (Nicotiana tabacum L. cv. Petit Havana SRl). This gene encodes isopentenyltransferase and thus, upon expression, induces cytokinin production (Akiyoshi et al., 1984; Barry et al., 1984; Buchmann et al., 1985). Different levels of expression of the ipt-gene were obtained by linking its coding sequences to other promoters. As well as the genuine promoter of the T-DNA ipt-gene of the nopaline Ti-plasmid (Pipt(nop)), we also used a light-inducible one, Pssu,being the promoter of a Pisum sativum gene encoding the small subunit (ssu) of Rubisco. As a control, a co-integrate harboring only the selection marker gene for kanamycin resistance was introduced (Deblaere et al., 1985).

Abstract

The study of the development of the photosynthetic apparatus may involve the measurement of the capacity of the electron transport by polarographic methods. This can be done by using the classical Rank Brother Oxygen Electrode(1).
