Abstract: A QTL analysis for three different adaptive traits was performed in an F 1 progeny of Castanea sativa Mill. The female and male parents originated from two Turkish chestnut populations adapted to a drought and humid environment, respectively. QTLs for bud flush, growth and carbon isotope discrimination were detected over a 3-year period. Bud set was also recorded in the last year of measurement. Thirty-five individual QTLs were detected for phenology, 28 for growth and 17 for carbon isotope discrimination, mos… Show more

“…A very similar range of values was observed for a Pinus pinaster full-sib family (Brendel et al 2002b). A higher range (around 6‰) was reported for a Castanea sativa family (Casasoli et al 2004), likely caused by this family having been constructed from parents that had specifically been chosen from provenances known to differ in their carbon isotope discrimination (Lauteri et al 1997). In the present study, the range was largest in 2001, corresponding to the driest climatic conditions during the harvest period within this study.…”

“…QTL with large effects for δ 13 C We detected ten significant, "unique" QTL for δ 13 C in the present study, whereas, Casasoli et al (2004) before conclusions can be drawn on the adaptive potential for W i among the different species. The occurrence of orthologous microsatellites and ESTs in the oak and chestnut maps enabled a comparison of the QTL positions between the two genomes (Casasoli et al 2006).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…However, no clear trend in correlations based on within-species diversity between growth and d 13 C can be deduced from the literature on perennial species (Zhang et al, 1994;Nguyen-Queyrens et al, 1998;Johnsen et al, 1999;Prasolova et al, 2001;Brendel et al, 2002;Xu et al, 2003;Weih et al, 2006;Monclus et al, 2012). Similar to our study, either absent or positive correlations have been found in Pinus pinaster (Marguerit et al, 2014) and Castanea sativa (Casasoli et al, 2004). As already discussed by Brendel et al (2002), the relationship between growth and WUE depends theoretically on the relative influence of the variability in New Phytologist photosynthesis (independent of stomatal limitations) compared with the variability in stomatal conductance.…”

“…In our study, we were able to map the largest number of SNP markers (4578 SNP markers) using GBS sequencing. This number significantly surpassed the marker count obtained in previous maps [12,21,22,36,37]. Meanwhile, our map, with a marker interval of 0.4 cM, showed the shortest average genetic interval and the highest density compared to any previous maps constructed for this genus.…”
