Arab, Leila; Seegmueller, Stefan; Kreuzwieser, Juergen; Eiblmeier, Monika; Rennenberg, Heinz published the artcile< Atmospheric pCO2 impacts leaf structural and physiological traits in Quercus petraea seedlings>, Recommanded Product: D-Glucosaccharic acid, the main research area is Quercus seedling leaf structural physiol trait oxidative stress ROS; Amino acid; Carbohydrate; Carbon dioxide; Cellulose; Glutathione reductase; Lignin.

Sessile oak (Quercus petraea Liebl.) was grown for ca. half a year from seeds at ambient control (525 ppm), 750, 900, and 1000 ppm atm. pCO2 under controlled conditions. Increasing pCO2 enhanced biomass production, modified the cell wall composition of the leaves in favor of cellulose at the expense of lignin, and enhanced the foliar non-structural carbohydrate level, in particular the sucrose content; as well as total N content of leaves by increased levels of all major N fractions, i.e., soluble proteins, total amino acids, and structural N. The enhanced total amino acid level was largely due to 2-ketoglutarate and oxalo acetate-derived compounds Increasing pCO2 alleviated oxidative stress in the leaves as indicated by reduced H2O2 contents. High in vitro glutathione reductase activity at reduced H2O2 contents suggests enhanced ROS scavenging, but increased lipid peroxidation may also have contributed, as indicated by a neg. correlation between malone dialdehyde and H2O2 contents. Almost all these effects were at least partially reversed, when pCO2 exceeded 750 or 900 ppm. Apparently, the interaction of atm. pCO2 with leaf structural and physiol. traits of Q. petraea seedlings is characterized by a dynamic response depending on the pCO2 level.

Fukudome, Chiaki; Takisawa, Rihito; Nakano, Ryohei; Kusano, Miyako; Kobayashi, Makoto; Motoki, Ko; Nishimura, Kazusa; Nakazaki, Tetsuya published the artcile< Analysis of mechanism regulating high total soluble solid content in the parthenocarpic tomato fruit induced by pat-k gene>, Application of C6H10O8, the main research area is parthenocarpic tomato fruit soluble solid patk gene expression.

Total soluble solid (TSS) in tomatoes is an important trait that affects consumer’s preference. Previous studies have observed high TSS content in parthenocarpic tomato fruits induced by a parthenocarpic gene, pat-k. However, the mechanisms regulating high TSS content remain unknown. Hence, we have investigated the water content, metabolites involved with high TSS content, and gene expression related to starch synthesis in tomato fruits to elucidate the mechanism regulating high TSS content. We have found that independent of fruit water content, parthenocarpic fruits induced by pat-k had higher TSS content than pollinated fruits on Pat-k homozygous plants. Addnl., metabolome anal. of mature fruits has revealed that fructose influenced the difference in TSS content between pollinated fruits on Pat-k homozygous plants and the parthenocarpic fruits on pat-k homozygous plants. Furthermore, high performance liquid chromatog. (HPLC) anal. showed that not only fructose contents but also glucose contents were higher in the parthenocarpic fruits on pat-k homozygous plants than pollinated fruits on Pat-k homozygous plants, suggesting that increases in these sugar contents influenced the high TSS content in the pat-k-induced parthenocarpic fruits. We also have found that parthenocarpic fruits had high starch content and upregulated Sus4, which is involved in starch synthesis, during the early stages of fruit development. Since previous reports have suggested that high starch content during the early stages of fruit development attributed to high sugar content in mature tomato fruits, our results suggest that high accumulation of starch in young fruits could be involved with high TSS content in parthenocarpic fruits induced by pat-k.
