The 80% ethanol extract of Alstonia yunnanensis afforded five new monoterpenoid indole alkaloids: 11-hydroxy-6,7-epoxy-8-oxo-vincadifformine (1), 14-chloro-15-hydroxy- vincadifformine (2), perakine N4-oxide (3), raucaffrinoline N4-oxide (4), and vinorine N1,N4-dioxide (5), together with three known compounds: 11-methoxy-6,7-epoxy-8-oxo- vincadiffor
MicroRNAs (miRNAs) are a class of small RNAs (sRNAs) that repress gene DC Power Adapter expression via high complementary binding sites in target mRNAs (messenger RNAs).Many miRNAs are ancient, and their intricate integration into gene expression programs have been fundamental for plant life, controlling developmental programs and executing respons
Post-transcriptional regulation has emerged as a key mechanism for regulating stem cell renewal and differentiation, which is essential for understanding tissue regeneration and homeostasis.Poly(A)-binding proteins are a family of RNA-binding proteins that play a vital role in post-transcriptional regulation by controlling mRNA stability and protei
Mitogen-Activated Protein Kinase (MAPK) cascades are conserved signaling modules that integrate multiple signaling pathways.One level of control on the activity of MAPKs is through their negative regulators, MAPK phosphatases (MKPs).Therefore, MKPs also play an integrative role for plants responding to diverse environmental stimulus; but the mechan
Quinoa (Chenopodium quinoa) is a seed crop of the Andean highlands and Araucanian coastal regions of South America that has recently expanded in use and production beyond its native range.This is largely due its superb nutritional value, consisting of protein that is rich in essential amino acids along with vitamins and minerals.Quinoa also present
