PIF1 directly and indirectly regulates chlorophyll biosynthesis to optimize the greening process in Arabidopsis.
Plants depend on light signals to modulate many aspects of their development and optimize their photosynthetic capacity. Phytochromes (phys), a family of photoreceptors, initiate a signal transduction pathway that alters expression of a large number of genes to induce these responses. Recently, phyA and phyB were shown to bind members of a basic helix-loop-helix family of transcription factors ...
متن کاملEIN3/EIL1 cooperate with PIF1 to prevent photo-oxidation and to promote greening of Arabidopsis seedlings.
The ability to switch from skotomorphogenesis to photomorphogenesis is essential for seedling development and plant survival. Recent studies revealed that COP1 and phytochrome-interacting factors (PIFs) are key regulators of this transition by repressing the photomorphogenic responses and/or maintaining the skotomorphogenic state of etiolated seedlings. Here we report that the plant hormone eth...
متن کاملScientific Correspondence Experimental Approach to Elucidating the Mechanism of Light-Independent Chlorophyll Biosynthesis in Greening Barley
Etiolated seedlings of angiosperms illuminated for a few hours and then returned to darkness continue to accumulate chlorophyll (Chl) a (Popov and Dilova, 1969; Adamson et al., 1997, and refs. therein). In leaves of barley (Hordeum vulgare) seedlings and leaves of Tradescancia albiflora, Chl content was increase in darkness by 20% to 30% and by 38% to 69%, respectively (Adamson et al., 1980; Wa...

متن کاملTOR-inhibitor insensitive-1 (TRIN1) regulates cotyledons greening in Arabidopsis
Target of Rapamycin (TOR) is an eukaryotic protein kinase and evolutionally conserved from the last eukaryotic common ancestor (LECA) to humans. The growing evidences have shown that TOR signaling acts as a central controller of cell growth and development. The downstream effectors of TOR have been well-identified in yeast and animals by using the immunosuppression agent rapamycin. However, les...
