  • Salicylic acid (SA) is a signal molecule that mediates many biotic and abiotic stress-induced physiological responses in plants. In the current study the protective effects of SA on cold stress-caused oxidative damage and photosynthesis inhibition in jasmine plants (Jasminum sambac) were examined.

  • Photosynthesis is an important physiological process in plants. It plays a crucial role in plant growth and development. In this study, we investigated the impact of zerovalent cobalt nanoparticles on the photosynthesis and expressing of gene involving in this process in leave of soybean Glycine max (L.) Merr “DT26” at different growth stages. The results showed that treatment of zerovalent cobalt nanoparticles made in Vietnam and USA (with two doses of 0.17 and 16.

  • 2016 marked the 50th anniversary of the discovery of Hatch-Slack pathway, more popularly known as the C4 photosynthetic pathway in sugarcane leaves. Since then, there had been a significant development in understanding the C4 syndrome and its evolutionary background. C4 photosynthesis produces almost a quarter of the world’s entire primary productivity, despite having merely a few plant lineages to compete with. This clearly depicts the extraordinary capacity of the system to effectively trap carbon and converting it into plant biomass.

  • LIFE ON EARTH ULTIMATELY DEPENDS ON ENERGY derived from the sun. Photosynthesis is the only process of biological importance that can harvest this energy. In addition, a large fraction of the planet’s energy resources results from photosynthetic activity in either recent or ancient times (fossil fuels). This chapter introduces the basic physical principles that underlie photosynthetic energy storage and the current understanding of the structure and function of the photosynthetic apparatus (Blankenship 2002). The term photosynthesis means literally “synthesis using light.

  • THE CONVERSION OF SOLAR ENERGY to the chemical energy of organic compounds is a complex process that includes electron transport and photosynthetic carbon metabolism (see Chapters 7 and 8). Earlier discussions of the photochemical and biochemical reactions of photosynthesis should not overshadow the fact that, under natural conditions, the photosynthetic process takes place in intact organisms that are continuously responding to internal and external changes. This chapter addresses some of the photosynthetic responses of the intact leaf to its environment....

  • Using the energy from sunlight, photosynthesis converts carbon dioxide into organic compounds. In this process, water is also oxidized to oxygen, necessary to sustain respiring organisms. Photosynthesis is one of the most important reactions on Earth, and it is a scientific field that is intrinsically interdisciplinary, with many research groups examining it.The advances in characterization techniques and their application to the field have improved our understanding of photosynthesis.

  • This book is aimed at providing applied aspects of photosynthesis. Different research groups collected their valuable results from the study of this interesting process. In this book, there are two sections: Fundamental and Applied aspects. All sections have been written by experts in their fields. Book chapters present different and new subjects, from photosynthetic inhibitors, to interaction between flowering initiation and photosynthesis. The book is the result of the effort of many experts, and I would like to take this opportunity to thank all contributors for their chapters.
