“…Other potential sources of variation are genotyping errors, an excess of missing values and the mapping of distorted markers (Hackett and Broadfoot 2003). Given the probabilistic nature of genetic maps, the re-ordering of tightly linked markers will generally produce a version of the map only marginally less probable than the most probable one, so this practice is quite frequently followed to improve alignment quality (Cervera et al 2001;Jeuken et al 2001;Lespinasse et al 2000;Lombard and Delourme 2001;Sebastian et al 2000). The further alignment of the "Wild" and "Est" LGs with 15 of the Sonnante et al (2011) globe artichoke x wild cardoon LGs using 31 common markers evidenced the assignment of 14 SSR loci (ten CyEM, four CELMS) to a specific LG for the first time in a C. cardunculus map.…”

An F 1 mapping population was bred by crossing an accession of wild cardoon with a single Argentinian globe artichoke plant of the variety "Estrella del Sur FCA" with a view to generate new C. cardunculus linkage maps. Genotyping was conducting using a set of 553 SRAP, SSR, AFLP and SNP markers.The 1,465.5 cM map based on the segregation of alleles present in the wild cardoon parent comprised 214 loci distributed across 16 linkage groups (LGs), while the 910.1 cM globe artichoke based map featured 141 loci falling into 12 LGs and the total length. Three of the morphological traits (inflorescence spininess, leaf spininess and head color) for which the parents contrasted were inherited monogenically, and the genes conditioning them were mapped. A set of 48 co-dominant loci was used to align the LGs with those derived from a reference SSRbased consensus map of the species.

“…The clustered arrangements of markers in LG16 are in contrast to more spaced marker alignment in the female map of family M, and clustering behavior of markers was also evident in LG10#, 12#, 16#, and 17$ (Figure 1). Mapping imprecision caused by sampling variations associated with sample sizes and statistical treatments (Liu 1998;Lespinasse et al 2000), or environmental differences between crossing experiments (Levine 1955;Simchen and Stamberg 1969;Beavis and Grant 1991), may be responsible for the within-individual map differences among the closely clustered markers (i.e.,…”

This study presents linkage maps for the Pacific abalone (Haliotis discus hannai) based on 180 microsatellite DNA markers. Linkage mapping was performed using three F 1 outbred families, and a composite linkage map for each sex was generated by incorporating map information from the multiple families. A total of 160 markers are placed on the consolidated female map and 167 markers on the male map. The numbers of linkage groups in the composite female and male maps are 19 and 18, respectively; however, by aligning the two maps, 18 linkage groups are formed, which are consistent with the haploid chromosome number of H. discus hannai. The female map spans 888.1 cM (Kosambi) with an average spacing of 6.3 cM; the male map spans 702.4 cM with an average spacing of 4.7 cM. However, we encountered several linkage groups that show a high level of heterogeneity in recombination rate between families even within the same sex, which reduces the precision of the consolidated maps. Nevertheless, we suggest that the composite maps are of significant potential use as a scaffold to further extend the coverage of the H. discus hannai genome with additional markers.

AbstrakBeberapa tantangan dalam kegiatan perakitan klon unggul baru tanaman karet (Hevea brasiliensis Muell. Arg.) melalui metode p e r s i l a n g a n b u a t a n ( k o nve n s i o n a l ) diantaranya adalah membutuhkan waktu yang lama, sifat heterozigositas yang tinggi dan tingkat keberhasilan yang belum optimal. Bioteknologi diharapkan dapat menjadi metode pendukung dalam menjawab t a n t a n g a n y a n g t e r j a d i t e r s e b u t . Perkembangan teknik in vitro dan rekayasa genetika telah memberikan terobosan baru dalam perbanyakan dan perbaikan genetik tanaman karet. Pemanfaatan bioteknologi telah berdampak pada proses perbaikan g e n e t i k t a n a m a n k a r e t d a l a m h a l produktivitas, kesehatan tanaman, dan peningkatan toleransi terhadap cekaman. Selain itu penggunaan marka molekuler sangat bermanfaat untuk percepatan seleksi dalam kegiatan pemuliaan tanaman karet. Teknik tersebut juga berguna dalam identifikasi klon dan tetua, analisis keanekaragaman genetik, pengawasan hasil persilangan buatan, penciri klon dan biologi reproduksi. Tulisan ini menjabarkan tentang pendekatan bioteknologi untuk meningkatkan potensi genetik tanaman karet.
