“…The existence of differentiation in adaptive traits among populations can be supposed due to its long-range distribution throughout southern Europe that exposes this species to varying environmental conditions. Studies aimed to evaluate traits of adaptive significance related to climate change (water use efficiency, bud burst, bud set and growth) were carried out in some European chestnut populations from contrasting environmental conditions (Pliura and Eriksson, 2002;Lauteri et al 1998Lauteri et al , 2004Fernández-López et al 2005). The results highlighted a strong population effect for most characters evaluated, indicating differences in adaptation among populations and across the distribution range of the species.…”

Microsatellite or simple sequence repeats (SSRs) are one of the most used markers in population genetic studies. SSR markers developed from expressed sequence tags (EST) have proved useful to examine functional diversity in relation to adaptive variation. The information provided by both genomic and genic microsatellite markers could offer more accurate indication on the distribution of the genetic diversity among and within populations assuming different evolutionary drivers. This is the first study on chestnut (Castanea sativa Mill.) in which the genetic diversity was evaluated by means of genomic (SSRs) and genic (EST-SSRs) microsatellite markers. We genotyped nine natural European chestnut populations distributed throughout representative areas of contrasting climatic conditions in the Mediterranean basin. Genomic SSRs showed significantly higher levels of diversity in terms of number of alleles, effective number of alleles, expected heterozygosity and level of polymorphism. Furthermore, there were significant differences in the level of differentiation among populations. The UPGMA analysis revealed different clustering pattern between populations, being the grouping according to geographic distances in the case of genomic SSRs and two differentiated groups based on the northern-southern distribution of the populations for ESTSSRs. Furthermore, the EST-SSR transferability among related Castanea and Quercus species was stated. Our results confirm that combining genomic SSRs and ESTSSRs is a useful tool to give complementary information to explain the genetic and adaptive diversity in chestnut.

“…populations, drought-adapted and wet-adapted, were identified (Lauteri et al 1999. WUE has been found to be a reliable indicator of complex adaptive mechanisms that differentiate wet-and drought-adapted populations (Lauteri et al 1997b(Lauteri et al , 1999(Lauteri et al , 2004. At juvenile stage, a slower increment of above-ground biomass was found for drought-adapted Mediterranean C. sativa genotypes compared to eastern wet-adapted genotypes, while at maturity growth patterns have changed in the opposite way (Villani et al 1992, Lauteri et al 1997a).…”

“…Ecophysiological studies highlighted different mechanisms of response to water stress depending on site conditions at the origin location (Lauteri et al 1997a(Lauteri et al , 1997b(Lauteri et al , 2004. Lauteri et al (1999) reported a higher capacity of photosynthesis and transpiration in C. sativa seedlings from populations from arid sites than in those from mesic sites. Studies of genetic variation in these traits in material from the whole distribution range of C. sativa indicated inter-and intra-population genetic variation in drought tolerance (Pliura & Eriksson 2002, Lauteri et al 2004).…”

Response of juvenile progeny of seven forest tree species and their populations to simulated climate change-related stressors, heat, elevated humidity and drought Alfas Pliūra The study aimed to evaluate response and phenotypic plasticity of juvenile progeny of seven forest tree species Pinus sylvestris, Picea abies, Quercus robur, Fraxinus excelsior, Alnus glutinosa, Betula pendula and Populus tremula and their populations to climate change-related stressors, simulated in a phytotron -heat and elevated humidity and heat and drought -in comparison to performance in ambient (control) conditions. Treatment effect on sapling morphometric, physiological and biochemical traits was significant except for health condition, transpiration and photosynthetic rates and water use efficiency (WUE). Species effect and species-by-treatment interaction were strongly significant in most traits studied, indicating a great inter-specific variability of responses to the applied treatments. Compared to control, stem diameter increment was lower for most species following both hot-wet and hotdry treatments, while treatment impact on height increment was less pronounced and sometimes even positive. Drought caused significant defoliation in P. tremula, A. glutinosa and B. pendula, while under hot-wet treatment the defoliation in most species was lower than in control. Following hot dry treatment, WUE in P. abies, P. sylvestris and B. pendula was lower than following both hot-wet treatment and control, while in P. tremula, A. glutinosa and Q. robur WUE was higher. This suggests that the latter species are able to maintain a balance between photosynthesis and transpiration. Photosynthetic rate was highest in P. tremula, B. pendula and A. glutinosa, however it was much more negatively affected by water deficit in these three species than in other tested species. In most cases, drought had a negative effect on production of pigments in deciduous tree species, which, together with increased amounts of malondialdehyde and hydrogen peroxide, indicated a presence of an oxidative stress. Significant population effect and population-by-treatment interactions found for most traits showed different plasticity and response of tree populations to the treatments. Although, only 19% of the populations showed significant ecovalencies. Some of the observed reactions may not be considered as adaptive acclimation as decreasing growth of some species and populations indicates deteriorating performance which may lead to changes in their competitiveness, thus compromising regeneration, persistence of natural successions and sustainability of forest ecosystems. Keywords: Climate Change, Stress, Growth, Physiology, Transpiration, Photosynthesis, Water Use Efficiency, Biochemical Parameters, Phenotypic Plasticity IntroductionOver the few last millennia forest tree species were subjected to conspicuous climatic and environmental changes and were forced to react to these changes by migration and genetic adaptation to new growing conditions (Huntley & Birks 1983)....

“…Some isozyme studies on the European chestnut indicate that Turkey has a range of potential of chestnut genotypes and is considered to have different subspecies of C. sativa Mill. (Pigluici et al, 1990;Villani et al, 1991;Villani et al, 1992;Lauteri et al, 1999). Although Turkey is the world's third largest producer of chestnuts, the production has decreased due to chestnut blight disease in recent decades (caused by Cryphonectria parasitica [Murrill] Barr) (Anonymous, 2008).…”

:Here we report phenotypic and genotypic differences among 14 Turkish chestnut genotypes. The genotypes were analyzed both genetically and for 30 morphological criteria comprising 12 qualitative and 18 quantitative characteristics. The phylogenetic relationships were determined between different chestnut genotypes selected from Sinop, Samsun, Artvin and Bartin provinces of Black Sea Region in Turkey. Morphological criteria were investigated biometrically using multivariate analysis. Ten morphological criteria were found to be effective for discrimination between the genotypes. Five morphological criteria accounts for 64.1% of the variability. These morphological criteria were the ratio of length of teeth to width of teeth, the ratio of length of hilum to length of fruit, cross section of leaves, the ratio of height of fruit to length of fruit and peeling of testa. The discrimination of morphological criteria was shown using cluster analysis, which created four main groups. Dice's coefficient was used to evaluate the genetic similarity by RAPD analysis, which created three main groups. The UPGMA method was used for the determination of phylogenetic trees. The genetic and morphological dendrograms were compared using the Mantel test, which gave a correlation of r=-0.33.

This study illustrates that the selected chestnut genotypes might be valuable genetic resources for future chestnut breeding programs.
