Potato Solanum tuberosum L. Phytoene Synthase Genes (StPSY1, StPSY2, and StPSY3) Are Involved in the Plant Response to Cold Stress.
The structure and phylogeny of the Solanum tuberosum L. phytoene synthase genes StPSY1, StPSY2, and StPSY3 were characterized. Their expression was studied in potato seedlings exposed to cold stress in the dark phase of the diurnal cycle to simulate night cooling. All of the three genes were activated as the temperature decreased, and the greatest response was observed for StPSY1. StPSY3 was for the first time shown to respond to cold stress and photoperiod. A search for cis-regulatory elements was carried out in the promoter regions and 5'-UTRs of the StPSY genes, and the regulation of all three genes proved associated with the response to light. A high level of cold-induced activation of StPSY1 was tentatively attributed to the presence of cis elements associated with sensitivity to cold and ABA.
期刊介绍：
Doklady Biological Sciences is a journal that publishes new research in biological sciences of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
