🌱 SPECIAL ISSUE RESEARCH 🌱

26S proteasome disassembly occurs during leaf senescence. While proteasomal subunit genes are up-regulated, proteasome protein levels do not increase. However, cytokinin application enhances proteasome activity - Wang et al.

Fig. 3 (shortened, full legend in paper): Regulation of proteasomal subunits during proteotoxic stress and leaf senescence. (A) Transcriptional response to proteotoxic stress of genes coding for proteasome subunits as assayed by promoter–GUS lines. Seedlings grown for 10 d on half-strength Murashige and Skoog (MS) medium with or without 15μM MG132 were stained for GUS activity and imaged. (B) Proteasomal subunit abundance during proteotoxic stress. Total protein extracts from 10-day-old wild-type seedlings treated for 2 d with either 30 μM MG132, 2 μM bortezomib, or DMSO were assessed by western blotting using protein-specific antibodies. Coomassie Brilliant Blue- (CBB) stained gels were used as loading control. (C) Expression of proteasomal subunit genes during leaf senescence as visualized by promoter–GUS reporter lines. Shown are the results for the first leaf pair, harvested from either 15-day-old plants (young) or 43-day-old plants (old).

Fig. 2.Confocal microscopy of N. punctiforme strains. Filaments from the indicated strains were taken from cultures grown in BG110 medium (not induced; A) or after incubation for 24 h in the presence of Anthoceros agrestis exudates (hormogonia induction; B) and visualized by confocal microscopy. Merged (2 channels) show the overlay of autofluorescence (magenta) and GFP fluorescence (green). Merged (3 channels) represent the overlay of magenta autofluorescence, bright field, and green GFP fluorescence. Hormogonia are identified as short filaments with small cells. Scale bar=20 μm.

It is not always safe to repair DNA Damage. Sometimes, cells "just bypass it".

During DNA replication, repair of lesions on DNA can be dangerous. Cells instead "tolerate" DNA damage and focus on finishing replication.
