Outline of Final Research Achievements |
Overwintering plants exhibits high levels of cold tolerance, which is acquired through the process of cold acclimation (CA). This acquired cold tolerance is rapidly reduced during cold de-acclimation (DA) and plants resume growth after sensing warm temperatures. In order to better understand plant growth and development, it is important to decipher the functional mechanisms of the CA and DA process. In this study, it is demonstrated that many cold-inducible genes were transcribed and translated, however a similar number of cold-inducible genes were not translated during the CA and were translated at a later stage, DA. Due to the disjunction between the up-regulation of specific genes and the lack of corresponding protein accumulation during CA, is likely that the translation of proteins during DA was primed with stored mRNA. This data imply that these are likely regulated by translational regulation, which alters protein expression patterns in response to environmental alterations.
