WebDOG1 is a major seed dormancy factor in Arabidopsis (Bentsink et al., 2006). DOG1 protein levels are tightly correlated with dormancy levels in freshly harvested seeds, with higher DOG1 levels causing delayed germination (Nakabayashi et al., 2012). 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.

WebJun 12, 2024 · To test whether bZIP67 is required for DOG1 expression during seed development, we performed quantitative (q)RT-PCR analysis of transcript abundance in … WebJul 29, 2024 · The principle QTL determining SET (SET1: dormancy cycling) is physically close on chromosome 5, but is distinct from DOG1. We show that SET1 and two other SET QTLs each contain a candidate gene (AHG1, ANAC060, PDF1 respectively) closely associated with DOG1 and abscisic acid signalling and suggest a model for the control of … can azithromycin cause breakthrough bleeding

WebMar 22, 2024 · Bryant et al. recently reported that increased expression of DOG1 under low-temperature conditions is directly regulated by bZIP67, and indirectly by LEC1. These … WebOct 1, 2024 · The first DOG1 gene identified was Arabidopsis DOG1, which was specifically expressed in seeds to delay seed germination [20]. The expression of Arabidopsis DOG1 is known to rely directly on basic LEUCINE ZIPPER TRANSCRIPTION FACTOR67 (bZIP67) [21] and indirectly on LEAFY COTYLEDON1 (LEC1) [22]. 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. fishing at crystal river florida
