BACKGROUND As the world population ages, chronic diseases such as diabetes,
cardiovascular disease, cancer, and neurodegeneration become ever more prevalent …

Plants are challenged by a variety of biotic or abiotic stresses, which can affect their growth
and development, productivity, and geographic distribution. In order to survive adverse …

Drought is a main abiotic stress that restricts plant growth and development. The increased
global demand of anti-cancer alkaloids extracted from periwinkle (Catharanthus roseus) is …

Physio-biochemical responses of pistachio varieties including Pistacia vera
L.'Ghazvini'(GH), P. vera 'Ghermez-Pesteh'(GP) and P. atlantica subsp. mutica (M) were …

In recent years, extreme environmental cues such as abiotic stresses, including frequent
droughts with irregular precipitation, salinity, metal contamination, and temperature …

Silicon can increase salt tolerance, but the underlying mechanism has remained unclear.
Here, we investigated the effect of silicon on polyamine metabolism and the role of …

Abstract Hydrogen peroxide (H 2 O 2) is a key signaling molecule that mediates a variety of
physiological processes and defense responses against abiotic stress in higher plants. In …

Drought stress affects a vast range of morphological, physiological and biochemical
characteristics in plants; however, exogenous application of osmotically active materials …

Arginine decarboxylase (ADC)-mediated putrescine biosynthesis plays an important role in
plant stress responses, but the transcriptional regulation of ADC in response to abiotic stress …

In the current research, four seven-month-old pistachio rootstocks named UCB-1, Badami,
Ghazvini and Kale-Ghouchi were exposed to control, drought, salinity and drought+ salinity …
