“…Va´squez- Robinet et al (2010) investigated the behavior of heat-shock proteins during photosynthetic acclimation and different levels of water stress in loblolly pine seedlings. Their results suggested that a cycle of mild stress conditioned the trees to adapt to a more severe stress.…”

Plants as sessile organisms are exposed to persistently changing stress factors. The primary stresses such as drought, salinity, cold and hot temperatures and chemicals are interconnected in their effects on plants. These factors cause damage to the plant cell and lead to secondary stresses such as osmotic and oxidative stresses. Plants cannot avoid the exposure to these factors but adapt morphologically and physiologically by some other mechanisms. Almost all stresses induce the production of a group of proteins called heat-shock proteins (Hsps) or stress-induced proteins. The induction of transcription of these proteins is a common phenomenon in all living things. These proteins are grouped in plants into five classes according to their approximate molecular weight: (1) Hsp100, (2) Hsp90, (3) Hsp70, (4) Hsp60 and (5) small heat-shock proteins (sHsps). Higher plants have at least 20 sHsps and there might be 40 kinds of these sHsps in one plant species. It is believed that this diversification of these proteins reflects an adaptation to tolerate the heat stress. Transcription of heat-shock protein genes is controlled by regulatory proteins called heat stress transcription factors (Hsfs). Plants show at least 21 Hsfs with each one having its role in regulation, but they also cooperate in all phases of periodical heat stress responses (triggering, maintenance and recovery). There are more than 52 plant species (including crop ones) that have been genetically engineered for different traits such as yield, herbicide and insecticide resistance and some metabolic changes.In conclusion, major heat-shock proteins have some kind of related roles in solving the problem of misfolding and aggregation, as well as their role as chaperones.

“…Recent transcriptome and proteome analyses have focused on responses to osmotic stress in various plant species. The results have indicated the involvement of general processes in altering the gene expression of plants, including crops and woody plants, such as Arabidopsis, rice, maize, wheat, barley, sorghum, soybean, tomato, chickpea, cotton, poplar, loblolly pine, grapevine, and cassava [84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101]. Most of these works have used macro-or microarrays and recently they identified the mass of transcriptomes using next-generation sequencing.…”

“…Recent research has focused on the photosynthetic acclimation processes during mild water stress to identify adaptive responses in the natural environment. Transcriptome profiles of loblolly pine under drought stress were correlated with physiological data, showing photosynthetic acclimation to mild drought stress and inhibition of photosynthesis under severe drought stress [92,103]. Under long-term or mild stress conditions that mimic the natural environment, plants acclimate to the stress by means of various molecular and physiological processes, which control plant growth and development [91,125,141].…”
