WebThe activation of DOG1 expression leading to increased PD requires that bZIP-transcription factor 67 (bZIP67) be bound to the DOG1 promoter. Although DOG1 is mainly expressed in seeds, other organs are also capable of doing so. 3. ROS and Nucleic Acid Modifications during Seed Dormancy. WebApr 8, 2024 · Plant Cell Basic LEUCINE ZIPPER TRANSCRIPTION FACTOR67 acts downstream of LEAFY COTYLEDON1 to induce DELAY OF GERMINATION1 expression during Arabidopsis seed maturation and to establish primary dormancy. Seed dormancy governs the timing of germination, one of the most important developmental transitions in …

WebMoreover, DOG1 expression is known to be increased by cold (6). Bryant et al. (7) showed that LEUCINE ZIPPER TRANSCRIPTION FACTOR67 (bZIP67) protein increases in abundance when seeds perceive cold during maturation and that this transactivates DOG1 and thereby helps to establish primary dormancy. WebZIPPER TRANSCRIPTION FACTOR 67 (bZIP67) acts downstream of LEAFY COTYLEDON 1 (LEC1) to transactivate DOG1 by binding G-box-like cis elements on the DOG1 promoter, thereby enhancing primary dormancy (Bryant et al., 2024). The ABA and DOG1 pathways converge downstream of the ABA-HYPERSENSITIVE GERMINATION 1 (AHG1) and how to make your mouse black

WebJul 29, 2024 · Potentially this behaviour provides a sensitive response to the environment that can differ between ecotypes. Recently, basic LEUCINE ZIPPER TRANSCRIPTION … WebThe DOG1 becomes modified (i.e., inactivated) during seed after-ripening (AR), and its levels in viable seeds do not correlate with germination potential. Interestingly, it was recently found that the transcription factor (TF) bZIP67 binds to the DOG1 promoter. This is required to activate DOG1 expression leading to enhanced seed dormancy. WebDOG1 expression is under tight developmental and environmental regulation, but the transcription factors involved are not known. Here we show that basic LEUCINE ZIPPER … mugwort herb meaning
