A red/far-red light-responsive bi-stable toggle switch to control gene expression in mammalian cells [PDF]

open access: yes, 2013
Growth and differentiation of multicellular systems is orchestrated by spatially restricted gene expression programs in specialized subpopulations. The targeted manipulation of such processes by synthetic tools with high-spatiotemporal resolution could ...

The effect of red light on the germination of a Brazilian Pteridophyte

open access: yesBrazilian Archives of Biology and Technology, 1999
The effects of red light on the germination of spores of Cheilantes concolor Langsd & Fisch were investigated in this study. The spores were spread in the Mohr (1956) nutritional solution after Dyer’s modifications (1979).

The V471 Tauri System: A Multi-datatype Probe [PDF]

open access: yes, 2015
V471 Tauri, a white dwarf--red dwarf eclipsing binary in the Hyades, is well known for stimulating development of common envelope theory, whereby novae and other cataclysmic variables form from much wider binaries by catastrophic orbit shrinkage.

Growth and Physiological Responses of Lettuce Grown under Pre-Dawn or End-Of-Day Sole-Source Light-Quality Treatments

open access: yesHorticulturae, 2018
The objective of this study was to evaluate growth and physiological responses of ‘Cherokee’ and ‘Waldmann’s Green’ lettuce (Lactuca sativa) exposed to small changes in light quality and intensity within a 24-h period. Three

The Expression of ELF4-Like Genes Is Influenced by Light Quality in Petunia

open access: yesAgronomy, 2020
The signals from photoreceptors modify plant morphogenesis and regulate the timing of flowering. In the long-day plant petunia, flowering is accelerated under blue (B) and white (W) light compared to red (R) light.
