saussurea obvallata/nicotine

Saussurea involucrata Kar. et Kir. is a hardy, dicotyledonous plant featured by strong tolerance to severe stress conditions. In a previous study, we created a cDNA library to characterize genetic factors associated with the cold acclimation response of S. involucrata. The full-length cDNA of one

Chalcone isomerase (CHI; EC 5.5.1.6) is a key enzyme in the flavonoid biosynthesis pathway. We isolated a CHI gene (SmCHI) from a cDNA library derived from Saussurea medusa (Asteraceae) cell cultures. The cDNA and genomic sequences of SmCHI are the same; in other words, this gene is intronless. The

Adverse environmental conditions, such as cold and drought, can inhibit plant growth, development, and productivity. The isolation and characterization of stress response genes from stress-tolerant plants can provide a better understanding of the underlying adaptive mechanisms. In this study, a

A full-length cDNA encoding a MYB-related regulatory gene was isolated from a cDNA library prepared from mRNAs of the red line callus of S. medusa by TD-PCR. The cDNA, designated SmP, is 969 nucleotides long and has an open reading frame of 771 bp with a deduced amino acid sequence of 256 residues.

Members of the 70 kD heat-shock gene family are highly conserved across a wide range of organisms. In an effort to learn more about the evolution and possible functions of extreme environment plant Saussurea medusa Maxim hsp70, we isolated a cDNA clone encoding a putative cytosolic member (Smhsp70)

Snow lotus (Saussurea involucrata (Kar. & Kir.) Sch. Bip.) is an economically important medicinal herb increasingly grown in China in recent years. During the summer and autumn of 2005, 2006, and 2007, a necrosis of unknown etiology was observed on leaves in commercial production areas in

Dehydrins are late embryogenesis abundant proteins that help regulate abiotic stress responses in plants. Overexpression of the Saussurea involucrata dehydrin gene SiDHN has previously been shown to improve water-use efficiency and enhance cold and drought tolerance of transgenic tobacco. To

Saussurea involucrata Kar. et Kir. is a hardy dicotyledonous plant capable of tolerating severe abiotic stress conditions. In a previous study, we created a cDNA library to determine what factors are associated with the cold acclimation response in S. involucrata. From this, a full-length cDNA of a
