The DNA damage response and DNA recombination are two interrelated mechanisms involved in maintaining the integrity of the genome, but in plants they are poorly understood. RecQ is a family of genes with conserved roles in the regulation of DNA recombination in eukaryotes; there are seven members in Arabidopsis. Here we report on the functional analysis of(More)
The Arabidopsis genome contains seven genes that belong to the RecQ family of ATP- dependent DNA helicases. RecQ members in Saccharomyces cerevisiae (SGS1) and man (WRN, BLM and RecQL4) are involved in DNA recombination, repair and genome stability maintenance, but little is known about the function of their plant counterparts. The Arabidopsis thaliana(More)
TRR14 is an unknown protein that was first identified as a component of Arabidopsis responses to trehalose treatment. Phylogenic analysis showed that TRR14 belongs to a seven-gene family in Arabidopsis. Close homologues of TRR14 were found in plants and many cyanobacteria. GFP expression analysis showed that TRR14 is located in the chloroplast. GUS::TRR14(More)
The roots of Onosma dichroantha, contain substantial amounts of shikonin/alkannin derivatives, which are considered as edible natural colors with distinguished anti-inflammatory, antibacterial, antiviral, as well as antitumor activities. In this study, a response surface methodology coupled with numerical optimization modeling techniques were implemented to(More)
Soybean (Glycine max L. Merr) is a commercially important crop that is sensitive to most abiotic stresses. Successful genetic transformation that has been widely used for yield improvements of many commercial crops needs efficient and reproducible plant regeneration protocols, in which the optimum concentrations of plant growth regulators play crucial(More)
