Abstract
DNA damage caused by internal and external stresses negatively affects plant growth and development. In this, DNA repair enzymes play an important role in recognizing and repairing the caused DNA damage. The first key enzymes in the base excision repair (BER) pathway are DNA glycosylases. In this paper, we present updated knowledge on the classification, phylogeny and conserved structural domains of DNA glycosylases in the plant base excision repair pathway. It describes the key roles played by the DNA glycosylases in plant stress responses, and focuses on the molecular mechanisms of plant stress tolerance from the perspective of the DNA repair system. New opportunities for the development of plant-derived DNA repair genes and DNA repair enzyme resources are discussed.
期刊介绍:
Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
