Science, 1981
Zooplankton grazers consume appreciable amounts of algae that are not digested. Indigestibility has been considered of adaptive value to the algae and an unqualified disadvantage to the grazer. In Cartesian diver experiments, freshly killed copepods ( Acanthocyclops vernalis ) produced significant amounts of oxygen ...

Science, 1989
Although the concept of an artificial photosynthetic reaction center that mimics natural electron- and energy-transfer processes is an old one, in recent years major advances have occurred. In this review, some relatively simple molecular dyads that mimic certain aspects of photosynthetic electron transfer and singlet or triplet energy transfer are ...

Photosynthesis Research, 2010
Online access to the Internet and the World Wide Web have become important for public awareness and for educating the world's population, including its political leaders, students, researchers, teachers, and ordinary citizens seeking information. Relevant information on photosynthesis-related Web sites and other online locations is grouped into several

Molecular Biotechnology, 1996
The levels of individual photosynthetic proteins can be independently decreased by the Agrobacterium-mediated transformation of plants with antisense RNA constructs. Protocols for the introduction of such constructs into Agrobacterium, the Agrobacterium-mediated transformation of tobacco leaf disks, and the screening and analysis of the transgenic ...

The Beginning of Photosynthesis
Origins of Life, 1974There is no evolutionary continuity between photochemical abiosynthesis and bacterial photosynthesis. Rather, the photosynthetic bacteria are descendants of fermenters that did not use light. Photosynthesis and respiration, both using electron flow coupled with phosphorylation, have a common origin ('conversion hypothesis'), but photosynthesis came ...

Photosynthesis and respiration
Archives of Biochemistry and Biophysics, 1963Abstract The effect of light on oxygen uptake and production by algae has been studied. Illumination was found to influence oxygen uptake by two mechanisms. Oxygen uptake was found to be inhibited at low light intensities and accelerated at medium to high intensities. The inhibition of uptake was mainly sensitized by chlorophyll a.

Photochemistry and Photobiology, 1996
Carotenoids are usually considered to perform two major functions in photosynthesis. They serve as accessory light harvesting pigments, extending the range of wavelengths over which light can drive photosynthesis, and they act to protect the chlorophyllous pigments from the harmful photodestructive reaction which occurs in the presence of oxygen ...

A list of photosynthesis conferences and of edited books in photosynthesis
Photosynthesis Research, 2004This paper is a general appendix to the three parts of 'Celebrating the millennium - historical highlights of photosynthesis research' (Photosynthesis Research, Vols~73(2002), 76(2003), 80(2004)). The major part of this paper includes a comprehensive list of most of the edited volumes on research in the area of photosynthesis.

Carotenoids and Photosynthesis
2016Carotenoids are ubiquitous and essential pigments in photosynthesis. They absorb in the blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and so expand the wavelength range of light that is able to drive photosynthesis.

The Dynamics of Photosynthesis
Annual Review of Genetics, 2008Despite recent elucidation of the three-dimensional structure of major photosynthetic complexes, our understanding of light energy conversion in plant chloroplasts and microalgae under physiological conditions requires exploring the dynamics of photosynthesis. The photosynthetic apparatus is a flexible molecular machine that can acclimate to metabolic
