“…2). This result is consistent with the previous report which showed that the GSH contents in plants were increased by the enhancement of sulfur metabolism (Rennenberg et al 2007). The increase of the volumetric GSH concentration during GSH fermentation in the MET16 over-expressing strain was due to the synergetic effect of the increases in the cell concentration and the intracellular GSH content.…”

Glutathione (GSH) is a valuable tri-peptide that is widely used in the pharmaceutical, food, and cosmetic industries. Glutathione is produced industrially by fermentation using Saccharomyces cerevisiae. In this study, we demonstrated that engineering in sulfate assimilation metabolism can significantly improve GSH production. The intracellular GSH content of MET14 and MET16 over-expressing strains increased up to 1.2 and 1.4-fold higher than that of the parental strain, respectively, whereas those of APA1 and MET3 overexpressing strains decreased. Especially, in the MET16 overexpressing strain, the volumetric GSH concentration was up to 1.7-fold higher than that of the parental strain as a result of the synergetic effect of the increases in the cell concentration and the intracellular GSH content. Additionally, combinatorial mutant strains that had been engineered to contain both the sulfur and the GSH synthetic metabolism synergistically increased the GSH production. External addition of cysteine to S. cerevisiae is well known as a way to increase the intracellular GSH content; however, it results a decrease in cell growth. This study showed that the engineering of sulfur metabolism in S. cerevisiae proves more valuable than addition of cysteine as a way to boost GSH production due to the increases in both the intracellular GSH content and the cell growth.

“…γ-ECS, the enzyme used in the first step of GSH biosynthesis is found to be regulatory enzyme and its activity is regulated by GSH in feedback mechanism. 114,115 Cys, a final product of S assimilation pathway, is supposed to be the rate-limiting factor for GSH biosynthesis (Fig. 1).…”

“…The congruence observed for SNP_154 (in gene APS) between the two gradients can therefore be interpreted as a signature of systematic divergent selection by temperature (Figure 3). APS is a key enzyme of the sulfate reduction pathway, which is involved in biotic and abiotic stress defense (Rennenberg et al 2007). Finally, we found more correlations between allelic frequencies and temperatures than between allelic frequencies and precipitations, suggesting that these correlations likely reflect adaptation for bud flush, as temperature is the main environmental gradient underlying phenological variation (Vitasse et al 2009).…”

We explored single nucleotide polymorphism (SNP) variation in candidate genes for bud burst from Quercus petraea populations sampled along gradients of latitude and altitude in Western Europe. SNP diversity was monitored for 106 candidate genes, in 758 individuals from 32 natural populations. We investigated whether SNP variation reflected the clinal pattern of bud burst observed in common garden experiments. We used different methods to detect imprints of natural selection (F ST outlier, clinal variation at allelic frequencies, association tests) and compared the results obtained for the two gradients. F ST outlier SNPs were found in 15 genes, 5 of which were common to both gradients. The type of selection differed between the two gradients (directional or balancing) for 3 of these 5. Clinal variations were observed for six SNPs, and one cline was conserved across both gradients. Association tests between the phenotypic or breeding values of trees and SNP genotypes identified 14 significant associations, involving 12 genes. The results of outlier detection on the basis of population differentiation or clinal variation were not very consistent with the results of association tests. The discrepancies between these approaches may reflect the different hierarchical levels of selection considered (inter-and intrapopulation selection). Finally, we obtained evidence for convergent selection (similar for gradients) and clinal variation for a few genes, suggesting that comparisons between parallel gradients could be used to screen for major candidate genes responding to natural selection in trees.L OCAL adaptation of temperate forest trees to environmental variation has been widely investigated in common garden experiments or provenance tests (Langlet 1971;Matyas 1996; König 2005 for reviews). Comparisons of populations sampled over wide ranges have revealed continuous patterns of differentiation along environmental gradients (Wright 1976;Morgenstern 1996). Clinal variation along geographic gradients (latitude, altitude, longitude) is frequently reported for phenological traits (see Alberto et al. 2013 for a review). Congruent clines have been identified across species and across experiments within species, suggesting the occurrence of directional selection in response to identical environmental gradients. For example, in northern temperate spruces and pines, populations from northern latitudes flush earlier than southern populations (Wright 1976;Morgenstern 1996) and steep clines have been observed in species extending over large ranges of latitude (Pinus sylvestris in Scandinavia, Giertych 1991; Picea sitchensis in North America, Mimura and Aitken 2007). Bud burst clines have also been observed in northern temperate broadleaved trees, but following the opposite trend. In beech (von Wuehlisch et al. 1995), birch (Worrell et al. 2000), and sessile oak (Liepe 1993;Deans and Harvey 1995;Ducousso et al. 1996), southern populations flush earlier than northern populations. Similar clinal variation has also been repo...
