Mobile gene silencing in Arabidopsis is regulated by hydrogen peroxide
In plants and nematodes, RNAi can spread from cells from which it is initiated to other cells in the organism. The underlying mechanism controlling the mobility of RNAi signals is not known, especially in the case of plants. A genetic screen designed to recover plants impaired in the movement but not the production or effectiveness of the RNAi signal identified RCI3, which encodes a hydrogen pe...
متن کاملDetection of Hydrogen Peroxide by DAB Staining in Arabidopsis Leaves.
In this protocol, the in situ detection of hydrogen peroxide (one of several reactive oxygen species) is described in mature Arabidopsis rosette leaves by staining with 3,3'-diaminobenzidine (DAB) using an adaptation of previous methods (Thordal-Christensen et al., 1997; Bindschedler et al., 2006; Daudi et al., 2012). DAB is oxidized by hydrogen peroxide in the presence of some haem-containing ...
متن کاملAtGLB1 enhances the tolerance of Arabidopsis to hydrogen peroxide stress.
Hydrogen peroxide (H2O2) as a widespread molecule plays an important role in plant stress responses. Here, we showed that an Arabidopsis line overexpressing hemoglobin 1 (AtGLB1) can enhance its tolerance to severe hypoxic stress. In our research, Arabidopsis lines with different hemoglobin levels were employed to study the relationship between H2O2 level and the tolerance to hypoxic stress. Th...
متن کاملHydrogen Peroxide in Adaptation
The perception of the roles of H 2 O 2 in living systems has come a long way, transcending from H 2 O 2 being considered as (i) exclusively damaging; (ii) a necessary evil " unwanted but an inevitable product of aerobic metabolism " ; (iii) important for specific biological processes that involve ROS aggressiveness, such as the battle of the innate immune system with pathogens; and (iv) signall...
متن کاملHydrogen Peroxide in Cholera
Sir,?I read a note from the pen of Dr. N. C. Moitra, m.b., in the Indian Medical Gazettte, October number, on the use of hydrogen peroxide in cholera, in which he says that he wrote a short note in the Therapeutic Notes published by Parke, Davis and Co., but he gives no date as to when he had written this short note. Also he does not say as to whether he uses liqr. hydrogen peroxide B. P. (10 p...
