Genetic diversity was determined and compared by using 86 random amplified polymorphic DNA loci in 450 families originated from 18 Pinus brutia Ten. (Turkish red pine) seed sources. These seed sources were sampled at three different categories and included six seed stands from six different breeding zones and six seed orchards, and six plantations which were originated from the respective seed stands. Genetic diversity parameters among the plantations, seed orchards and seed stands were compared. There was no significant difference in genetic diversity parameters of seed sources, but the percentages of polymorphic loci were slightly higher in seed orchards than their natural counterparts. These results suggest that through phenotypic selection practiced genetic diversity residing in natural stands seems to be successfully captured in seed orchards. Mean F-ST values (F-ST = 0.10-0.11) did not vary among three different categories of seed sources. Seed orchards (F-IS = 0.03) and plantations (F-IS = 0.07) showed reduced locality inbreeding coefficients compared with seed stands (F-IS = 0.13). The dendrogram of seed stands based on genetic distances did not produce any clusters of populations that could be attributed to their geographic proximity. A representative portion of genetic diversity existing in natural populations of Turkish red pine appears to be captured in established seed orchards and plantations with seeds from seed stands.

The pattern of inheritance of genes conferring resistance to malathion and genetic consequences of linkage between an autosomal male-determining factor and resistance genes on the second chromosome were investigated in a strain of house fly, Musca domestica L., selected for malathion resistance. The second and fifth chromosomes contribute significantly to malathion resistance. The presence of a male-determining factor linked with the resistance genes on the second chromosome resulted in a strong sexual dimo...

The phylogenetic relationships of Drosanthe section of Hypericum genus (Hypericaceae) were analyzed by using non-coding chloroplast DNA region (trnL 3'-trnF) for 58 individuals. The section is represented by 23 taxa and nine of which are endemic to Turkey. The chloroplast phylogeny suggested that the members of this section belonged to a polyphyletic group, which imply at least two independent origins. The individuals of this section clearly formed two main clades. One clade included all members of this sec...

The present study was carried out to examine the interaction of vanadium and phosphorus and changes in heat shock genes to optimize the growth of chickpea genotypes. Two sets of hydroponic experiments were carried out using vanadium and phosphorus with five-level central composite design. Five levels of vanadium (0-1180 mu M) and phosphorus (0-100011 mu M) were used to evaluate their interactive effects. Plants fresh biomass and uptake of vanadium and phosphorus were influenced by vanadium and phosphorus ap...
Exceptional maternal lineage diversity in brown bears (Ursus arctos) from Turkey

The genetic diversity and phylogeography of maternal lineages in Ursus arctos Linnaeus, 1758 (the brown bear) have been studied extensively over the last two decades; however, sampling has largely been limited to the northern Holarctic, and was possibly biased towards lineages that recolonized the vast expanses of the north as the Last Glacial Maximum (LGM) ended. Here we report the genetic diversity and phylogeography of U.arctos from Turkey based on 35 non-invasive samples, including five from captive ind...
Genetic structure of black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled from the Bolkar Mountains
Tolun, AA; Velioğlu, E; Çengel, Burcu N; Kaya, Zeki (2000-01-01)
In order to determine the magnitude and pattern of genetic diversity among Anatolian Black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled in Bolkar Mountains and to recommend the potential populations which may be suitable for in situ conservation of genetic resources in this species, isoenzymes from 14 enzyme systems were investigated by starch gel electrophoresis. For this reason, open pollinated seed megagametophytes of half-sib families originated from the four populations (Camliyay...
