A wheat dehydrin gene (DHN-5) is inducible by either treatment with abscisic acid (ABA) or by abiotic stress such as drought and salinity. To further investigate the regulation of the gene, a 1,128-bp genomic fragment upstream of the DHN-5 translated sequence has been isolated, cloned, and designated as the ‘‘PrDHN-5’’ promoter. Sequence analysis of PrDHN-5 revealed the presence of cisregulator...

Dehydrins belongs to a large group of highly hydrophilic proteins known as Late Embryogenesis Abundant (LEA) proteins. It is well known that dehydrins are intrinsically disordered plant proteins that accumulate during the late stages of embryogenesis and in response to abiotic stresses; however, the molecular mechanisms by which their functions are carried out are still unclear. We have previou...

In this study, whether the addition of antifreeze protein (AFP) to a cryopreservative solution (plant vitrification 2 (PVS2)) is more effective in reducing freezing injuries Hosta capitata than PVS2 alone at different cold exposure times (6, 24, and 48 h) investigated. The upregulation C-repeat binding factor 1 (CBF1) dehydrin (DHN1) response low temperature was observed shoots. Shoots treated ...

Epidermal fragments enriched in guard cells (GCs) were isolated from the halophyte quinoa (Chenopodium Wild.) species, and response at proteome level was studied after salinity treatment of 300 mM NaCl for 3 weeks. In total, 2147 proteins identified, which 36% differentially expressed to stress GCs. Up downregulated included signaling molecules, enzyme modulators, transcription factors oxidored...

Wounding due to mechanical injury or insect feeding causes a wide array of damage to plant cells including cell disruption, desiccation, metabolite oxidation, and disruption of primary metabolism. In response, plants regulate a variety of genes and metabolic pathways to cope with injury. Tomato (Solanum lycopersicum) is a model for wound signaling but few studies have examined the comprehensive...

The wild tomato species Solanum chilense and S. peruvianum are a valuable non-model system for studying plant adaptation since they grow in diverse environments facing many abiotic constraints. Here we investigate the sequence evolution of regulatory regions of drought and cold responsive genes and their expression regulation. The coding regions of these genes were previously shown to exhibit s...

Germin gene expression in barley (Hordeum vulgare L.) seedlings responds to developmental and environmental cues. During seed germination, germin mRNA levels were maximal 2 d after the start of imbibition in control seedlings and declined to low levels by 6 d. When seeds were sown in the presence of 200 mM NaCl, germin mRNA levels were also maximal after 2 d, but NaCl treatment, which slowed se...
