Drought stress not only effect the population and activities of microorganisms inhabiting the
rhizosphere but also various physiological and biochemical process in plants that is …

Ultraviolet-B (UV-B) radiation has long been perceived as a stressor. However, a conceptual
U-turn has taken place, and UV-B damage is now considered rare. We question whether UV …

It emerged recently that there is an inter‐relationship between drought and ultraviolet‐B (UV‐
B) radiation in plant responses, in that both stresses provoke an oxidative burst. The …

UV-B radiation is a key environmental signal that initiates diverse responses in plants that
affect metabolism, development, and viability. Many effects of UV-B involve the differential …

Radiation is widespread in nature, including ultraviolet radiation from the sun, cosmic
radiation and radiation emitted by natural radionuclides. Over the years, the increasing …

During the past few years, considerable progress has been made in understanding how
plants protect themselves against oxidative stress. Genes encoding plant antioxidant …

Reactive Oxygen Species (ROS) play a key role in various events of seed life. In orthodox
seeds, ROS are produced from embryogenesis to germination, ie in metabolically active …

The behavior of the antioxidant defense system was studied in sunflower cotyledons
subjected to ultraviolet-B (UV-B) radiation. The two doses assayed (15.0 and 30.0 kJm− 2) …

We investigated the interactions of abscisic acid (ABA) in the responses of grape leaf tissues
to contrasting ultraviolet (UV)‐B treatments. One‐year‐old field‐grown plants of Vitis vinifera …

The leaf-structural adaptative strategies and the possible involvement of the antioxidative
system in the tolerance to salt stress were investigated in relation to leaf tissue senescence …
