| Research Abstract |
Plant purine catabolism has a relatively long history of physiological and biochemical studies particularly in ureide-type leguminous species, becauseit constitutes an integral part of the storage and translocation of symbiotically fixed nitrogen. In contrast, for the vast majority of plants that do not utilize a symbiotic association with Rhizobiumbacteria, the general role and physiological significance of purine degradation remains elusive. We found that dysfunction of purine catabolism impaired the plant growth under normal conditions and enhanced the stress sensitivity in hash environment, indicating a dual role in maintaining the growth and contributing to adaptation to stress.
