This 1989 book deals with the physical and chemical properties found in algae of different types (blue-green, red, golden-brown, yellow-green, brown and green). Methods used for extracting and purifying the pigments and their value in classifying the various types of algae are discussed in detail. This book contains detailed tables of the physical properties of the pigments (absorption and fluorescence-emission spectra and extinction coefficients), and brings together data on the distribution of algal pigments in relation to hypotheses of the evaluation of algae. It will be of value to anyone with an interest in phycology.

Penetration of light into aquatic ecosystems is greatly affected by the absorption and scattering processes that take place within the water. Thus within any water body, the intensity and colour of the light field changes greatly with depth and this has a marked influence on both the total productivity of, and the kinds of plant that predominate in, the ecosystem. This study presents an integrated and coherent treatment of the key role of light in aquatic ecosystems. It ranges from the physics of light transmission within water, through the biochemistry and physiology of aquatic photosynthesis, to the ecological relationships which depend on the underwater light climate.

Photosynthesis is a process on which virtually all life on Earth depends. To answer the basic questions at all levels of complexity, from molecules to ecosystems, and to establish correlations and interactions between these levels, photosynthesis research - perhaps more than any other discipline in biology - requires a multidisciplinary approach. Congresses probably provide the only forums where progress throughout the whole field can be overviewed. The Congress proceedings give faithful pictures of recent advances in photosynthesis research and outline trends and perspectives in all areas, ranging from molecular events to aspects of photosynthesis on the global scale. The Proceedings Book, a set of 4 (or 5) volumes, is traditionally highly recognized and intensely quoted in the literature, and is found on the shelves of most senior scientists in the field and in all major libraries.

Quite naturally, photosynthesis has achieved massive amounts of attention in recent years. Aside from being the most spectacular physiological process in plant growth, it is actually the key to our dealing with the potentially cataclysmic accumulation of carbon dioxide in the earth’s atmosphere. Unfortunately, while information is plentiful, all this attention has resulted in a scattered database on photosynthesis, with no contemporary starting point...at least until now. With the second edition of the Handbook of Photosynthesis, Mohammad Pessarakli once again fills the need for an authoritative and balanced resource by assembling a team of experts from across the globe. Together, they have created a comprehensive reference that in a single volume includes important background information, as well as the most recent research findings on photosynthesis. Completely Revised with Several New Chapters The handbook, a completely updated reworking of the critically acclaimed first edition, details all of the photosynthetic factors and processes under both normal and stressful conditions, covering lower and higher plants as well as related biochemistry and plant molecular biology. Divided into fourteen sections for ease of reference, with nearly 8000 bibliographic citations, the handbook contains authoritative contributions from over 80 scientists. It includes approximately 500 drawings, photographs, tables, and equations— all designed to reinforce and clarify important text material.

All biomass is derived from photosynthesis. This provides us with food fuel, as well as fibre. This process involves conversion of solar energy, via photochemical reactions, into chemical energy. In plants and cyanobacteria, carbon dioxide and water are converted into carbohydrates and oxygen. It is the best studied research area of plant biology. We expect that this area will assume much greater importance in the future in view of the depleting resources ofthe Earth's fuel supply. Furthermore, we believe that the next large increase in plant productivity will come from applications of the newer findings about photosynthetic process, especially through manipulation by genetic engineering. The current book covers an integrated range of subjects within the general field of photosynthesis. It is authored by international scientists from several countries (Australia, Canada, France, India, Israel, Japan, Netherlands, Russia, Spain, UK and USA). It begins with a discussion of the genetic potential and the expression of the chloroplast genome that is responsible for several key proteins involved in the electron transport processes leading to O evolution, proton release and the production of 2 NADPH and A TP, needed for CO fixation. The section on photosystems discusses 2 how photosystem I functions to produce NADPH and how photosystem II oxidizes water and releases protons through an "oxygen clock" and how intermediates between the two photosystems are produced involving a "two electron gate".

"Details all of the photosynthetic factors and processes under both normal and stressful conditions--covering lower and higher plants as well as related biochemistry and plant molecular biology. Contains authoritative contributions from over 125 experts in the field from 28 countries, and includes almost 500 drawings, photographs, micrographs, tables, and equations--reinforcing and clarifying important text material."

These Proceedings comprise the majority of the scientific contributions that were presented at the VIIth International Congress on Photosynthesis. The Congress was held August 10-15 1986 in Providence, Rhode Island, USA on the campus of Brown University, and was the first in the series to be held on the North American continent. Despite the greater average travel distances involved the Congress was attended by over 1000 active participants of whom 25% were registered students. This was gratifying and indicated that photosynthesis will be well served by excellent young scientists in the future. As was the case for the VIth International Congress held in Brussels, articles for these Proceedings were delivered camera ready to expedite rapid publication. In editing the volumes it was interesting to reflect on the impact that the recent advances in structure and molecular biology had in this Congress. It is clear that cognizance of structure and molecular genetics will be even more necessary in the design of experiments and the direction of future research.

This volume provides a detailed examination of phycobiliproteins, the photosynthetic antenna pigments found in algae.
