Global changes of environment changes such as temperature increase, drought, salinity,
heavy metals and chilling deadly affected to plants. Growth, development and reproductive
stages of plants disrupted by damages of stressors. As a first harbingers of stress condition
producing and accumulation of ROS happens in the cell. Naturally, accumulation of ROS is
toxic to plant cells, and lead to changes such as protein degradation, lipid peroxidation and
breaks of DNA, Hormonal dis-balance and other changes happened after stress treatment.
However, Cross tolerance mechanism serves as defensive strategy in plants during the stress
condition affected again. Obviously, accumulation of ROS, RCS, RNS have lethal consequences, however, priming by heat/cold shock ameliorated crop’s physiological markers of plants. Unfortunately, the molecular mechanism of Cross tolerance does not study deeply. Future perspectives cross tolerance and priming by short term stress will be useful method to save crop productivity under temperature condition.
