| Description
| - Dehydriny jsou biochemicky jasně vymezenou skupinou patřící do rodiny tzv. LEA proteinů, které ve svých molekulách obsahují minimálně jednu kopii konzervované sekvence bohaté na lysin, tzv. K-segment. Dehydriny jsou vysoce hydrofilní, obsahují hodně glycinu a polárních aminokyselin. Zůstávají rozpustné ve vodných roztocích i po varu, což lze efektivně využít k jejich izolaci. Předpokládá se, že dehydriny působí v rostlinných buňkách v průběhu dehydratace jako chaperony, tj. chrání jiné proteiny a další vnitrobuněčné struktury před nepříznivými konformačními změnami, vedoucími ke ztrátě biologické aktivity. U některých dehydrinů byly popsány též další funkce, např. funkce kryoprotektivní, funkce zhášečů volných kyslíkových radikálů (ROS) či vazba některých kovových iontů. Chlad, tj. nízké teploty nad bodem mrazu (často vymezené intervalem 0 – 10 °C), většinou v přírodě předchází mrznutí (tj. teploty pod bodem mrazu), které je spojeno s přirozenou dehydratací rostlinných pletiv v důsledku tvorby extrac (cs)
- Dehydrins present a distinct biochemical group of late embryogenesis abundant (LEA) proteins characterised by the presence of a lysine-rich amino acid motif, the K-segment. They are highly hydrophilic, soluble upon boiling, and rich in glycine and polar amino acids. It is proposed that they can act as emulsifiers or chaperones in the cells, i.e., they protect proteins and membranes against unfavourable structural changes caused by dehydration. Cold usually precedes freezing in nature and induces many physiological and biochemical changes in the cells of freezing-tolerant plant species (cold-acclimation) that enable them to survive unfavourable conditions. It is demonstrated that the induction of dehydrin expression and their accumulation is an important part of this process in many dicotyledons (both herbaceous and woody species), and also in winter cultivars of cereals, especially wheat and barley. Some mechanisms which are proposed to be involved in regulation of dehydrin expression are discussed,
