Supplemental blue and red light promote lycopene synthesis in tomato fruits
Journal of Integrative Agriculture, 2019 Lycopene, one of the strongest natural antioxidants known and the main carotene in ripe tomato, is very important for human health. Light is well known to be one of the most important environmental stimuli influencing lycopene biosynthesis; specifically,

Protein Kinase Activity of Phytochrome A Positively Correlates With Photoresponses in Arabidopsis
Frontiers in Plant Science, 2021 Plant phytochromes are known as autophosphorylating serine/threonine protein kinases. However, the functional importance of their kinase activity is not fully elucidated.

Light and temperature receptors and their convergence in plants
Biologia Plantarum, 2020 Light and temperature are two essential environmental cues for plants, helping to optimize plant body architecture and physiology. To sense a broad spectrum of sun radiation spanning from UV-B to far-red wavelength, plants are equipped with a ...

Beyond the photocycle-how cryptochromes regulate photoresponses in plants? [PDF]
, 2018 Cryptochromes (CRYs) are blue light receptors that mediate light regulation of plant growth and development. Land plants possess various numbers of cryptochromes, CRY1 and CRY2, which serve overlapping and partially redundant functions in different plant

Phytochrome Immunoaffinity Purification [PDF]
Plant Physiology, 1979 We have developed a phytochrome immunoaffinity purification procedure that yields undegraded oat (Avena sativa L., cv. Garry) phytochrome of greater than 98% purity within 2 hours when starting with a brushite-purified preparation. Immunoaffinity-purified phytochrome, except for its greater purity, is indistinguishable from conventionally purified ...

Temperature, light and nitrate sensing coordinate Arabidopsis seed dormancy cycling resulting in winter and summer annual phenotypes [PDF]
, 2013 Seeds use environmental cues to sense the seasons and their surroundings to initiate the plants life cycle. Dormancy cycling underlying this process is extensively described, but the molecular mechanism is largely unknown.

Underground roots monitor aboveground environment by sensing stem-piped light
Communicative & Integrative Biology, 2016 Light is a critical environmental cue for plant growth and development. Plants actively monitor surrounding environments by sensing changes in light wavelength and intensity.

Shade delays flowering in Medicago sativa [PDF]
, 2019 Shade intolerant plants respond to the decrease in the red (R) to far-red light (FR) ratio (R:FR) occurring under shade by elongating stems and petioles and re-positioning leaves, in a race to out-compete neighbors for the sunlight resource.

The primary structural photoresponse of phytochrome proteins captured by a femtosecond X-ray laser
eLife, 2020 Phytochrome proteins control the growth, reproduction, and photosynthesis of plants, fungi, and bacteria. Light is detected by a bilin cofactor, but it remains elusive how this leads to activation of the protein through structural changes.
