Abstract:Abstract: Telomeres are nucleoprotein structures at the ends of chromosomes in eukaryotic cells, which have the functions of protecting the integrity of linear chromosome ends, inhibiting DNA damage and regulating cell senescence. Telomeres consist of tandem DNA repeats and proteins. Telomerase is a special type of reverse transcriptase that can extend the telomeres by adding the TTTAGGG repeat sequence to maintain cell telomere length. It comprises two subunits, telomerase RNA (TER) and telomerase reverse transcriptase (TERT). Herein, the regulatory research progress of telomeres, telomerase and related genes in plant growth and aging process are reviewed, with the hope of providing theoretical basis for related research and application.
