Identification and characterization of key circadian clock genes of tobacco hairy roots: putative regulatory role in xenobiotic metabolism

The circadian clock is an endogenous system that allows organisms to daily adapt and optimize their physiology and metabolism. We studied the key circadian clock gene (CCG) orthologs in Nicotiana tabacum seedlings and in hairy root cultures (HRC). Putative genes involved in the metabolism of xenobio...

We studied the key circadian clock gene (CCG) orthologs in Nicotiana tabacum seedlings and in hairy root cultures (HRC). Putative genes involved in the metabolism of xenobiotic compounds (MXC) were selected and their expression profiles were also analyzed. Seedlings and HRC displayed similar diurnal variations in the expression profiles for the CCG examined under control conditions (CC). MXC-related genes also showed daily fluctuations with specific peaks of expression. However, when HRC were under phenol treatment (PT), the expression patterns of the clock and MXC-related genes were significantly affected. In 2-week-old HRC, PT downregulated the expression of NtLHY, NtTOC1, and NtPRR9 while NtFKF1 and NtGI genes were upregulated by phenol. In 3-week-old HRC, PT also downregulated the expression of all CCG analyzed and NtTOC1 was the most affected. Following PT, the expression of the MXC-related genes was upregulated or displayed an anti-phasic expression profile compared to the expression under CC. Our studies thus provide a glimpse of the circadian expression of clock genes in tobacco and the use of HRC as a convenient system to study plant responses to xenobiotic stresses.Fil: Sosa Alderete, Lucas Gastón.

description The circadian clock is an endogenous system that allows organisms to daily adapt and optimize their physiology and metabolism. We studied the key circadian clock gene (CCG) orthologs in Nicotiana tabacum seedlings and in hairy root cultures (HRC). Putative genes involved in the metabolism of xenobiotic compounds (MXC) were selected and their expression profiles were also analyzed. Seedlings and HRC displayed similar diurnal variations in the expression profiles for the CCG examined under control conditions (CC). MXC-related genes also showed daily fluctuations with specific peaks of expression. However, when HRC were under phenol treatment (PT), the expression patterns of the clock and MXC-related genes were significantly affected. In 2-week-old HRC, PT downregulated the expression of NtLHY, NtTOC1, and NtPRR9 while NtFKF1 and NtGI genes were upregulated by phenol. In 3-week-old HRC, PT also downregulated the expression of all CCG analyzed and NtTOC1 was the most affected. Following PT, the expression of the MXC-related genes was upregulated or displayed an anti-phasic expression profile compared to the expression under CC. Our studies thus provide a glimpse of the circadian expression of clock genes in tobacco and the use of HRC as a convenient system to study plant responses to xenobiotic stresses.
