The pipetting of pear (Pyrus communis cv Bartlett) suspension cultures was followed by a substantial but transient decrease in heat sensitivity. During a culture cycle, pear cells were most sensitive to heat at day 3, which coincided with the period of most active cell division. To minimize serious artifacts, the influence of culture handling and age on parameters such as heat sensitivity must

-PDF- Heat Stress Signal Transduction In Plant Cells

Plant tolerance to heat stress proved to be entirely dependent on the signaling flow of information by which the plant can sense the changes in its surrounding environment and signal its genes to respond by producing special proteins to protect it-self. Any changes or manipulations in this signaling flow of information will presumably lead to a modification in the genetic expression inside the

Plant heat stress: concepts directing future research

Interest in plant heat stress tolerance has never been greater, driven largely by concerns of how managed and natural ecosystems will be affected by climate change. Increasing amounts of greenhouse gases result in increased energy in the atmosphere, a phenomenon termed “radiative forcing”. As a result, global mean annual temperatures are predicted to increase by 0.3-4.8 °C by 2100 (IPCC

Heat stress occurs when temperatures rise above a threshold level long enough to cause irreversible damage to plants. The . severity of heat stress depends on the duration, intensity, and time of year when high temperatures occur, the condition of the plant, and their immediate environment (Teskey et al., 2015).

Abiotic Stress Signaling and Responses in Plants: Cell

The primary signal caused by drought is hyperosmotic stress, which is often referred to simply as osmotic stress because a hypo-osmotic condition typically is not a significant problem for plant cells. Salt stress has both osmotic and ionic or ion-toxicity effects on cells. The secondary effects of drought and salt stresses are complex and include oxidative stress; damage to cellular
