"Alstonia scholaris (L.) R.Br. is a popular timber and medicinal tree species in Indonesia.The species is valued for its quality light wood timber and for its medicinal properties. Information on its existing genetic potential is currently lacking. The present study was carried out to optimize PCR and to screen primers among accessions collected from different part of region in Indonesia using random amplified polymorphic DNA (RAPD) markers in order to suggest appropriate primer and PCR conditions used in A.scholaris. Results showed that 26 primers generated 575 scorable bands of which 524 (92 %) were polymorphic. Fourteen highly polymorphic primers (100% polymorphic) are recorded from 48 primer used, i.e.OPA-2, OPA-03, OPA-05, OPA-06, OPA-10,OPA-12, OPA-15, OPA-18, OPA-19, OPC-03, OPC-10, OPC-12, OPC-17, and OPN-14. Based on the RAPD markers, a dendrogram was constructed using the UPGMA method.The range of genetic distance was from 0.18-0.45.The molecular dara grouped the genotypes into three main clusters."

"ABSTRAKPenelitian ini merupakan lanjutan dari penelitian sebelumnya mengenai ekspresi gen pektolitik terhadap pelunakan buah Capsicum annuum. Hasil penelitian tersebut menunjukkan bahwa ekspresi gen pektolitik terlihat lebih rendah pada aksesi yang lebih tahan pembusukan. Perbedaan pola ekspresi gen tersebut memunculkan dugaan adanya pengaturan ekspresi gen yang terkait ketahanan pembusukan pada tingkat nukleotida. Studi mengenai perbedaan pola basa nukleotida pada C. annuum belum dilakukan, sehingga perlu dilakukan penelitian lebih lanjut terhadap profil sekuens kandidat gen pektolitik pada aksesi C. annuum. Penelitian dilakukan dengan menggunakan tiga aksesi C. annuum yaitu SSP sebagai aksesi yang tahan pembusukan dan Kopay serta Kencana yang tidak tahan pembusukan. Gen yang diujikan pada penelitian ini ialah poligalakturonase, pektinesterase 1, pektinesterase 2, dan pektat liase. Hasil penelitian menunjukkan bahwa hanya sebagaian profil sekuens gen kandidat yang berhasil diketahui yaitu gen poligalakturonase pada SSP dengan panjang basa 1.005 bp dan gen pektinesterase 2 pada SSP dengan panjang basa 765 bp serta Kopay dengan panjang basa 777 bp. Profil sekuens gen pektinesterase 1 dan gen pektat liase ketiga aksesi belum dapat diketahui.

ABSTRACTThis study is a follow up study on Capsicum annuum or pepper fruits regarding expression of cell wall degrading genes which have been done previously. Previous research has shown that polygalacturonase genes expression appears to be low in accesssions that more resistant to decay. Difference in gene expression pattern thought to be due to the regulation of gene expression associated with decay resistance at the nucleotide level. Therefore, a further research is needed. The study was conducted using three accessions of C. annuum, SSP is a decay resistant accession, and Kopay and Kencana are not resistant to decay. The genes tested in this study were polygalacturonase, pectate lyase, pectinesterase 1, and pectinesterase 2. The results showed that only some sequence profile of candidate genes were known, for instance the polygalactonase gene on SSP with a base length of 1.005 bp and the pectinesterase 2 gene on SSP with 765 bp and Kopay with 777 bp. The sequence profile of pectinesterase 1 gene and pectate liase gene are not yet known."
