“…We suggest that arginylation is involved in the various metabolic changes that plants undergo in order to adapt to the absence of light. Bryophytes grown in darkness accumulate less chlorophyll than light-grown controls (Takio et al, 1988) implicating a downregulation of photosynthesis in the dark. In addition, moss shoots show a certain level of etiolation including elongation in the dark (Bierfreund et al, 2004;Possart & Hiltbrunner, 2013).…”

SummaryThe importance of the arginyl-tRNA protein transferase (ATE), the enzyme mediating posttranslation arginylation of proteins in the N-end rule degradation (NERD) pathway of protein stability, was analysed in Physcomitrella patens and compared to its known functions in other eukaryotes.We characterize ATE:GUS reporter lines as well as ATE mutants in P. patens to study the impact and function of arginylation on moss development and physiology.ATE protein abundance is spatially and temporally regulated in P. patens by hormones and light and is highly abundant in meristematic cells. Further, the amount of ATE transcript is regulated during abscisic acid signalling and downstream of auxin signalling. Loss-of-function mutants exhibit defects at various levels, most severely in developing gametophores, in chloroplast starch accumulation and senescence. Thus, arginylation is necessary for moss gametophyte development, in contrast to the situation in flowering plants.Our analysis further substantiates the conservation of the N-end rule pathway components in land plants and highlights lineage-specific features. We introduce moss as a model system to characterize the role of the NERD pathway as an additional layer of complexity in eukaryotic development.

Photosynthetic ability in dark-grown Reboulia hemisphaerica and Barbula unguiculata cells in suspension culture

Suspension cultured cells of the liverwort, Reboulia hemisphaerica and of the moss, Barbula unguiculata were independently subcultured in the medium containing 2% glucose in the dark or in the light for more than one year, and the photosynthetic activities of the final cultures were determined. Throughout the culture period light-grown cells of both species contained high amount of chlorophyll (4 to 34 μg mg(-1) dry weight) and showed a high photosynthetic activity (10 to 84 μmol O2 mg(-1) chlorophyll h(-1)). Dark-grown cells of R. hemisphaerica showed the same level of chlorophyll content and photosynthetic O2 evolving activity as light-grown cells. Although chlorophyll content in dark-grown B. unguiculata cells was ten-fold lower than that in light-grown cells, the photosynthetic activity of these dark-grown cells was higher than that of light-grown cells based on chlorophyll content.
