Plants have evolved with intricate mechanisms to cope with multiple environmental stresses. To adapt with biotic and abiotic stresses, plant responses involve changes at the cellular and molecular levels. The current study was designed to investigate the effects of combinations of different environmental stresses on the transcriptome level of Arabidopsis genome using public microarray databases...

amorpha-4, 11-diene synthase (ads) gene is the first and important gene in artemisinin biosynthesis pathway that why for many researchers, the study of how to regulate of this gene is important. transcription factors can change the expression rate of several genes simultaneously. in this study, six wild accessions of artemisia annua, collected from golestan province, were used. many known trans...

background: sustainable and commercial production of secondary metabolites is a critical issue when dealing with its clinical application. efforts are still being made to look for biotic or abiotic elicitors with more efficient and universal effects on the improvement of secondary metabolites. objective: in order to evaluate the suitability of different biotic elicitors on p. harmala l. cell su...

Stream assemblages are structured by a combination of local (environmental filtering and biotic interactions) and regional factors (e.g., dispersal related processes). The relative importance of environmental and spatial (i.e., regional) factors structuring stream assemblages has been frequently assessed in previous large-scale studies, but biotic predictors (potentially reflecting local biotic...

Enteric bacteria exposed to the marine environment simultaneously encounter a variety of abiotic and biotic challenges. Among the former, light appears to be critical in affecting seawater survival; previous growth history plays a major part in preadaptation of the cells, and stationary phase cells are generally more resistant than exponentially growing ones. Predation, mostly by protozoa, is p...

Saleh A. and M. Pagés (2003): Plant AP2/ERF transcription factors. – Genetika, Vol. 35, No. 1, 37-50. Transcription factors (TFs) play important roles in plant development and its response to the biotic and abiotic stresses. AP2/ERF transcription factors family is unique to plants and a conserved AP2/ERF domain of about 60 amino acids characterized these transcription factors. AP2/ERF genes hav...

This study highlights the behaviour of Mercury in the abiotic and biotic segments of the Mandovi-Zuari estuarine system. Spatial, seasonal (Premonsoon and Postmonsoon) and tidal, distribution of THg in dissolved/particulate fractions, sediment concentrations were mapped of the river mouths, Mormugao Port, inner and outer environs of this estuarine system. Observed seasonal partition studies pro...
