  Title The circadian clock component, LHY, tells a plant when to respond photosynthetically to light in nature Type Journal Article
  Year 2017 Publication Journal of Integrative Plant Biology Abbreviated Journal J Integr Plant Biol  
  Volume 59 Issue 8 Pages 572-587  
  Keywords plants  
  Abstract The circadian clock is known to increase plant growth and fitness, and thought to prepare plants for photosynthesis at dawn and dusk; whether this happens in nature was unknown. We transformed the native tobacco, Nicotiana attenuata to silence two core clock components, NaLHY (irLHY) and NaTOC1 (irTOC1). We characterized growth and light-and dark-adapted photosynthetic rates (Ac ) throughout a 24 h day in empty vector-transformed (EV), irLHY, and irTOC1 plants in the field, and in NaPhyA-and NaPhyB1-silenced plants in the glasshouse. The growth rates of irLHY plants were lower than those of EV plants in the field. While irLHY plants reduced Ac earlier at dusk, no differences between irLHY and EV plants were observed at dawn in the field. irLHY, but not EV plants, responded to light in the night by rapidly increasing Ac . Under controlled conditions, EV plants rapidly increased Ac in the day compared to dark-adapted plants at night; irLHY plants lost these time-dependent responses. The role of NaLHY in gating photosynthesis is independent of the light-dependent reactions and red light perceived by NaPhyA, but not NaPhyB1. In summary, the circadian clock allows plants not to respond photosynthetically to light at night by anticipating and gating red light-mediated in native tobacco.

  Title The efficiency of different light sources in inducing spray carnation flowering Type Journal Article
  Year 1982 Publication Scientia Horticulturae Abbreviated Journal  
  Volume 18 Issue Pages 159--167  
  Keywords Plants  
  Abstract Light from Gro-lux fluorescent lamps, as a 4-h night break, was found to be more effective than incandescent light in promoting spray carnation flowering under natural daylight conditions. When the illuminations were applied for 4 h in the middle of the night, the effectiveness of a certain amount of radiant energy from incandescent light was found to be the same whether applied as intermittent or as continuous illumination.

  Title Ice plant growth and phytochemical concentrations are affected by light quality and intensity of monochromatic light-emitting diodes Type Journal Article
  Year 2018 Publication Horticulture, Environment, and Biotechnology Abbreviated Journal Hortic. Environ. Biotechnol.  
  Volume 59 Issue 4 Pages 529-536  
  Keywords Plants  
  Abstract The ice plant (Mesembryanthemum crystallinum L.), widely known to be an effective cure for diabetes mellitus, is also a functional crop. This study was conducted to examine the effects of light quality and intensity of monochromatic light-emitting diodes (LEDs) on ice plant growth and phytochemical concentrations in a closed-type plant production system. Ice plant seedlings were transplanted into a deep floating technique system with a recycling nutrient solution (EC 4.0 dS m−1, pH 6.5). Fluorescent lamps, as well as monochromatic red (660 nm) and blue (450 nm) LEDs, were used at 120 ± 5 or 150 ± 5 µmol m−2 s−1 PPFD with a photoperiod of 14 h/10 h (light/dark) for 4 weeks. Ice plants showed higher growth under the high light intensity treatment, especially under the red LEDs. Furthermore, the SPAD value and photosynthetic rate were higher under the red LEDs with 150 µmol m−2 s−1 PPFD. The ice plant phytochemical composition, such as antioxidant activity and myo-inositol and pinitol concentrations, were highest under the blue LEDs with 150 µmol m−2 s−1 PPFD. Total phenolic concentration was highest under the blue LEDs with 120 µmol m−2 s−1 PPFD. Despite a slightly different dependence on light intensity, phytochemical concentrations responded positively to the blue LED treatments, as compared to other treatments. In conclusion, this study suggests that red LEDs enhance ice plant biomass, while blue LEDs induce phytochemical
