Times Cited Count：50 Percentile：72.15(Plant Sciences)The error-prone DNA translation synthesis (error-prone TLS) has been well characterized in yeast and mammalians, but not in higher plants. Recent finding of an 
-disrupted mutant (
) in Arabidopsis suggested that the error-prone TLS is significant for tolerance to DNA damages in higher plant. To clarify the details of the error-prone TLS in higher plants, we analyzed the T-DNA inserted Arabidopsis mutants defective in or genes, which are thought to be involved in the error-prone TLS system. The mutant (
) was sensitive to UV-B and cisplatin. The mutant (
) was sensitive to long-term UV-B and cisplatin. These results suggest TLS mechanism exists in a higher plant and show that and have important roles in tolerating exposure to DNA-damaging agents, but their function might be redundant.

Times Cited Count：132 Percentile：92.51(Plant Sciences)PCIB (-chlorophenoxyisobutyric acid) is known as a putative antiauxin and is widely used to inhibit auxin action, although the mechanism of PCIB-mediated inhibition of auxin action is not characterized very well at molecular level. In the present work, we showed that PCIB inhibited BA::GUS expression induced by IAA, 2,4-D and NAA. PCIB also inhibited auxin dependent DR5::GUS expression. RNA hybridization and quantitative RT-PCR analyses suggested that PCIB reduced auxin-induced accumulation of transcripts of 
genes. In addition, PCIB relieved the reduction of GUS activity in 
transgenic line in which auxin inhibits GUS activity by promoting degradation of the AXR3NT-GUS fusion protein. Physiological analysis revealed that PCIB inhibited lateral root production, gravitropic response of roots and growth of primary roots. These results suggest that PCIB impairs auxin signaling pathway by regulating Aux/IAA protein stability, and thereby affects the auxin-regulated Arabidopsis root physiology.
