Hydrogen Peroxide Is a Second Messenger in the Salicylic Acid-Triggered Adventitious Rooting Process in Mung Bean Seedlings
In plants, salicylic acid (SA) is a signaling molecule that regulates disease resistance responses, such as systemic acquired resistance (SAR) and hypertensive response (HR). SA has been implicated as participating in various biotic and abiotic stresses. This study was conducted to investigate the role of SA in adventitious root formation (ARF) in mung bean (Phaseolus radiatus L) hypocotyl cutt...
متن کاملHydrogen Peroxide Is Involved in Salicylic Acid-Elicited Rosmarinic Acid Production in Salvia miltiorrhiza Cell Cultures
Salicylic acid (SA) is an elicitor to induce the biosynthesis of secondary metabolites in plant cells. Hydrogen peroxide (H2O2) plays an important role as a key signaling molecule in response to various stimuli and is involved in the accumulation of secondary metabolites. However, the relationship between them is unclear and their synergetic functions on accumulation of secondary metabolites ar...
متن کاملHydrogen peroxide: a signaling messenger.
Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays important roles in host defense and oxidative biosynthetic reactions. In addition there is growing evidence that at low levels, H2O2 also functions as a signaling agent, particularly in higher organisms. This review evaluates the evidence that H2O2 functions as a signaling agent in higher organisms in light of the...
متن کامل1 s Salicylic Resistance Acid a Translocated Signal of Systemic Acquired in Tobacco ?
Salicylic acid (SA) is a likely endogenous signal in the development of systemic acquired resistance (SAR) in some dicotyledonous plants. In tobacco mosaic virus (TMV)-resistant Xanthi-nc tobacco, SA levels increase systemically following the inoculation of a single leaf with TMV. To determine the extent to which systemic increases in SA result from SA export from the inoculated leaf, SA produc...
متن کاملHydrogen peroxide Acts as a Secondary Messenger for Production of Silymarin in Ag+ Elicited Silybum marianum Hairy Root Cultures
This study was performed to investigate the effect of Ag+ as an elicitor on the activity of antioxidant enzymes, content of H2O2, accumulation of total tocopherol and antioxidant activity in hairy root cultures of Silybum marianum (L.) Gaertn. The hairy roots were treated with 2 mM Ag+. The treated and non-treated hairy roots were harvested in the same time and data on H2O2 content, DPPH, tocop...
