“…This result was similar to other reports on methylation analysis in Arabidopsis (Cervera et al, 2002) and rice (Ashikawa, 2001). Similar results were also reported in tobacco amplified fragment length polymorphism (AFLP) (Denduangboripant et al, 2010) and SSR analyses. For example, 46 tobacco cultivars from 18 different countries were grouped based on their geographic origins and manufacturing quality traits (Ren and Timko, 2001).…”

DNA methylation plays an important role in the epigenetic regulation of gene expression during plant growth, development, and polyploidization. However, there is still no distinct evidence in tobacco regarding the distribution of the methylation pattern and whether it contributes to qualitative characteristics. We studied the levels and patterns of methylation polymorphism at CCGG sites in 48 accessions of allotetraploid flue-cured tobacco, Nicotiana tabacum, using a methylation-sensitive amplified polymorphism (MSAP) technique. The results showed that methylation existed at a high level among tobacco accessions, among which 49.3% sites were methylated and 69.9% allelic sites were polymorphic. A cluster analysis revealed distinct patterns of geography-specific groups. In addition, three polymorphic sites significantly related to tobacco mosaic virus (TMV) resistance were explored. This suggests that tobacco breeders should pay more attention to epigenetic traits.

“…Arslan and Okumus (2006) used RAPD markers in Turkish tobacco germplasm and they also reported that geographically closer populations were present in a single cluster. Denduangboripant et al (2010) used AFLP markers in tobacco and they also found that their studied material showed grouping on the basis of respective geographical regions. The grouping obtained in our study can be supported through this possible assumption, as Samsun Province is considered among the main tobacco-growing areas.…”

Knowledge of genetic diversity could be beneficial by contributing important information in the selection of breeding material. The objective of this study was to explore the genetic diversity and relationship in the Turkish tobacco germplasm with the iPBSretrotransposons marker that emerged as a universal method. A total of 90 landraces and 6 commercial cultivars collected from different geographical regions of Turkey were used in this study. Eleven most polymorphic iPBS-retrotransposons primers yielded a total of 119 scorable bands and 98 of these bands were found to be polymorphic (82.35%), with an average of 8.91 polymorphic fragments for each primer. The mean polymorphism information contents were found to be 0.33, ranging from 0.10 to 0.80. The unweighted pair group method with arithmetic mean revealed that the genotypes belonging to the same geographical regions were often present in the same group and very close to each other. Based on the Bayesian clustering model, the genetic structure of Turkish tobacco germplasm was divided into 2 main groups. This is first study to explore the genetic diversity of Turkish tobacco by the iPBS-retrotransposons and we believe that in future the results of this study will serve as a foundation for the development of new and improved tobacco varieties in Turkey and the rest of world.

“…Sejauh ini, daun tembakau diproses secara komersial sebagai bahan utama rokok dan cerutu [5]. Namun demikian, tembakau juga memiliki potensi untuk dikembangkan dalam industri kosmetik [6], bioenergy [7], biopestisida dan industri farmasi [8]. Selain itu, tanaman tersebut juga digunakan sebagai salah satu sistem model yang paling penting dalam pengembangan bioteknologi tanaman [9].…”

Pengaruh Pra-perlakuan Paraquat Terhadap Kandungan Asam Askorbat pada Tembakau (Nicotiana tabacum L.) var. MKY yang Dicekam Kekeringan

Kekeringan merupakan faktor utama yang membatasi pertumbuhan dan perkembangan tanaman serta berpengaruh terhadap produktivitas tanaman di seluruh dunia, utamanya di daerah tropis. Seperti halnya tanaman lain, tembakau juga mengembangkan mekanisme pertahanan terhadap cekaman kekeringan. Salah satu bentuk pertahanan tersebut yaitu tanaman melakuan mekanisme produksi antioksidan berupa asam askorbat. Penelitian ini bertujuan untuk mengetahui pengaruh paraquat (PQ) terhadap kandungan asam askorbat pada tembakau (Nicotiana tabacum L.) var. MKY yang dicekam kekeringan. Cekaman kekeringan dilakukan dengan cara melakukan penghentian pemberian air pada tanaman, serta digunakan PQ dengan konsentrasi 0.0005, 0.001, 0.0025, dan 0.005%. Parameter yang diukur adalah kandungan asam askorbat (AsA). Pemberian pra-perlakuan menggunakan paraquat dengan konsentrasi tersebut terbukti mampu meningkatkan kandungan asam askorbat. Paraquat dengan konsentrasi 0.001% dinilai merupakan konsentrasi yang paling optimal sebagai second messenger untuk meningkatkan respon N. tabacum dibawah cekaman kekeringan.
