The review covers literature bearing 1978 and 1979 publication dates that was available to the author up to the time of submission. , There are many responses in plants and animals to low fluence blue light with responses dating back to the lowest of organisms. The biological necessity of ‘knowing’ when illuminated has been described at length many times and it will here be considered axiomatic. The pigment system(s) responsible for many of the photoprocesses (as ascertained by action spectra… Expand
A Spectroscopic View of Some Recent Advances in the Study of Blue Light Photoreception
TLDR
A possible solution to the most recent version of the long-standing flavin-carotenoid controversy, the zeaxanthin hypothesis for higher plant phototropism, is presented and it is apparent that photolyase homologs such as CRY1 can explain the blue light portion of the action spectrum for hypocotyl elongation, assuming participation of the oxidized flavin.

TLDR
The carotenoid zeaxanthin may serve as the chromophore for a photoreceptor involved in blue-light-activated stomatal opening and some of the downstream events they are known to activate are discussed. Expand
PHOTORECEPTOR INTERACTION IN PLANT PHOTOMORPHOGENESIS: THE LIMITS OF EXPERIMENTAL TECHNIQUES AND THEIR INTERPRETATIONS
TLDR
There does not appear to be an adequate current theory to explain photoreceptor interactions, and issues discussed include the use of displacement transducers in growth studies, the induction of phytochrome‐type responses by blue light, and the relative importance of the photoreceptors. Expand
Seeing blue: the discovery of cryptochrome
TLDR
The recent first isolation of a blue-light photoreceptor, CRY1 (for cryptochrome), from Arabidopsis thaliana by molecular genetic techniques is focused on, primarily as they relate to the newly identified CRY 1Photoreceptor. Expand
Blue Light Sensing in Higher Plants*
TLDR
The most recent advances in the understanding of blue light perception and signaling with an emphasis on the cryptochrome and phototropin photosensory systems are reviewed. Expand
THE PHOTORECEPTORS OF THE HIGH IRRADIANCE RESPONSES OF PLANT PHOTOMORPHOGENESIS
The high irradiance responses (HIR) of plant photomorphogenesis are a class of light-dependent responses that are characterized by the following general properties [22,47,52,74] : (a) the fullExpand

TLDR
Gao et al. elegantly demonstrate that the Trp Triad is indeed not required for in vivo function of AtCRY1 and that photochemical activation of Trp triad mutants is not dependent upon ATP or other metabolites, presenting a more unified understanding of CRY photochemistry. Expand
The Study of Basic Photochemical and Photophysical Properties of Membrane-Bound Flavins: The Indispensible Prerequisite for the Elucidation of Primary Physiological Blue Light Action
Some 100 different physiological blue light responses are known today, and the list is growing steadily. It is safe to assume that all blue light photoreceptors are of ancient lineage and have beenExpand
The Blue Light Receptor(s): Primary Reactions and Subsequent Metabolic Changes
The growing awareness of blue-light-induced phenomena in plants and microorganisms is reflected in the increased research activity into an ever-increasing variety of blue light effects in biologicalExpand
Cryptochrome: the second photoactive pigment in the eye and its role in circadian photoreception.

TLDR
Genetic evidence shows that cryptochromes are circadian photoreceptors in Drosophila and Arabidopsis, raising the possibility that they may be universal circadian photoresceptors, and may provide new understanding of human diseases such as seasonal affective disorder and delayed sleep phase syndrome.

TLDR
It is concluded that there is an obligatory dependency (or sequential interaction) between theblue light effect and the light effect occurring through phytochrome, although the blue light photoreaction per se is not affected by the presence or absence of phy tochrome. Expand

Although in v i m studies have so far shown that enzyme activity control is not due to a direct effect of light on the enzyme, assessment of these researches could be made by bringing together the various different aspects and this might also lead to some unifying view. Expand
