Stomata regulate gas exchange through the aerial plant epidermis by controlling the width of a pore bordered by two guard cells. Little is known about the genes that regulate stomatal development. We screened cotyledons from ethyl methanesulfonate-mutagenized seeds of Arabidopsis by light microscopy to identify mutants with altered stomatal morphology. Two(More)
Although several mutations and genes affecting plant cytokinesis have been identified, mutant screens are not yet saturated and knowledge about gene function is still limited. A novel Arabidopsis mutation, cytokinesis defective1 (cyd1), was identified by partial or missing cell walls in stomata. Stomata with incomplete or no cytokinesis still differentiate(More)
An alcohol dehydrogenase from Candida parapsilosis CCTCC M203011 was characterized along with its biochemical activity and structural gene. The amino acid sequence shows similarity to those of the short-chain dehydrogenase/reductases but no overall identity to known proteins. This enzyme with unusual stereospecificity catalyzes an anti-Prelog reduction of(More)
UNLABELLED RELEVANCE TO ETHNOPHARMACOLOGY: Dahuangzhechong pill (DHZCP), a well-known and canonical Chinese medicine formula from "The Synopsis of Prescriptions of the Golden Chamber", is officially approved and recommended by Chinese association of integrative medicine for the prevention and treatment of hepatic fibrosis in China. AIM OF THE STUDY To(More)
OBJECTIVE EEG synchronization is usually estimated in terms of coherence amplitude, but the estimation is with apparent uncertainty because of the poor resolution both in time and frequency. The purpose of this work is to surmount this problem. METHOD A new definition of EEG synchronization index spectrum [SynI(f)] was developed basing on the distribution(More)
OBJECTIVE To study the response characteristics of left and right brain to signals from left (LVF) and right (RVF) visual fields during cognitive activity. METHOD ERPs at 9 locations to LVF and RVF signals were compared in 23 normal subjects in 3 task conditions: looking forward only (VC); making switch response to target signals (T) only (SR); making(More)
T he relationship between maternal short stature and gestational diabetes mellitus (GDM) remains controversial. While such an association has been shown in Europeans, South Americans, and Southern Asians (1–5), it was not demonstrated in Hungarians of European origin (6). Apart from ethnic differences, the contribution of the different components of height(More)
