Diterpenoids are important compounds for plant survival and have beneficial properties for humans. Bioactive abietanic diterpenes are synthesized in roots of Salvia sclarea (e.g. aethiopinone, 1-oxoaethiopinone, salvipisone, and ferruginol), but at a very low level (about 1 % of root dry weight). To enhance the biosynthesis of this interesting class of(More)
Salt and drought stress severely reduce plant growth and crop productivity worldwide. The identification of genes underlying stress response and tolerance is the subject of intense research in plant biology. Through microarray analyses, we previously identified in potato (Solanum tuberosum) StRGGA, coding for an Arginine Glycine Glycine (RGG) box-containing(More)
The identification of inhibitors of Hsp90 is currently a primary goal in the development of more effective drugs for the treatment of various types of multidrug resistant malignancies. In an attempt to identify new small molecules modulating the activity of Hsp90, we screened a small library of tetranortriterpenes. A high-affinity interaction with Hsp90(More)
Water-limiting conditions affect dramatically plant growth and development and, ultimately, yield of potato plants (Solanum tuberosum L.). Therefore, understanding the mechanisms underlying the response to water deficit is of paramount interest to obtain drought tolerant potato varieties. Herein, potato 10K cDNA array slides were used to profile(More)
Hsp90 C-terminal ligands are potential new anti-cancer drugs alternative to the more studied N-terminal inhibitors. Here we report the identification of a new dihydropyrimidinone binding the C-terminus, which is not structurally related to other well-known natural and nature-inspired inhibitors of this second druggable Hsp90 site.
