Book excerpt: Apart from the short-range interactions mediated by diffusion, long-scale interactions are indispensable for giant plant cells including internodal cells of Characeae because the inefficiency of diffusion for millimeter- and centimeter-scale distances should be counterbalanced by other mechanisms to ensure the integrity of cell metabolism. In this collection, the authors begin by presenting one approach for studying the cyclosis-mediated transmission of regulatory signals along the characean internode by illuminating a cell part with a narrow light beam and to observe the changes of modulated chlorophyll fluorescence occurring in response to this photostimulus at a fixed distance on the downstream side of the light spot.Following this, the features and characters of various chloroplast genomes that could be retrieved solely from the analysis of triplet composition were studied. Two types of triplet dictionaries were developed: the former lists all the triplets (with overlapping), so that each nucleotide yields a start for a triplet, and the latter is the entity where triplets do not overlap but also have no gaps between them.The authors go on to describe the effects of cytoplasm on the expression of cytoplasmic male sterility and other agronomically valuable traits in the grain sorghum and sorghum × Sudan grass hybrids, as well as on the combining ability for these traits. It is hypothesized that the cytoplasm, being a buffer between the external environment and the nuclear genome, processes environmental signals and thus has a significant effect on the manifestation of nuclear-encoded traits.A nonlocal strain gradient beam model is developed including the both hardening-stiffness and softening-stiffness size effects in conjunction with the geometrical nonlinearity in the concluding study. Via the variational approach, the governing differential equations are constructed corresponding to each nonlinear mechanical behavior of the lipid micro/nano-tubule surrounded by the cytoplasm biomedium.

Available in PDF, EPUB and Kindle. Book excerpt: The compartmentation of genetic information is a fundamental feature of the eukaryotic cell. The metabolic capacity of a eukaryotic (plant) cell and the steps leading to it are overwhelmingly an endeavour of a joint genetic cooperation between nucleus/cytosol, plastids, and mitochondria. Alter ation of the genetic material in anyone of these compartments or exchange of organelles between species can seriously affect harmoniously balanced growth of an organism. Although the biological significance of this genetic design has been vividly evident since the discovery of non-Mendelian inheritance by Baur and Correns at the beginning of this century, and became indisputable in principle after Renner's work on interspecific nuclear/plastid hybrids (summarized in his classical article in 1934), studies on the genetics of organelles have long suffered from the lack of respectabil ity. Non-Mendelian inheritance was considered a research sideline~ifnot a freak~by most geneticists, which becomes evident when one consults common textbooks. For instance, these have usually impeccable accounts of photosynthetic and respiratory energy conversion in chloroplasts and mitochondria, of metabolism and global circulation of the biological key elements C, N, and S, as well as of the organization, maintenance, and function of nuclear genetic information. In contrast, the heredity and molecular biology of organelles are generally treated as an adjunct, and neither goes as far as to describe the impact of the integrated genetic system.

Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Book excerpt: Plant Cell Organelles contains the proceedings of the Phytochemical Group Symposium held in London on April 10-12, 1967. Contributors explore most of the ideas concerning the structure, biochemistry, and function of the nuclei, chloroplasts, mitochondria, vacuoles, and other organelles of plant cells. This book is organized into 13 chapters and begins with an overview of the enzymology of plant cell organelles and the localization of enzymes using cytochemical techniques. The text then discusses the structure of the nuclear envelope, chromosomes, and nucleolus, along with chromosome sequestration and replication. The next chapters focus on the structure and function of the mitochondria of higher plant cells, biogenesis in yeast, carbon pathways, and energy transfer function. The book also considers the chloroplast, the endoplasmic reticulum, the Golgi bodies, and the microtubules. The final chapters discuss protein synthesis in cell organelles; polysomes in plant tissues; and lysosomes and spherosomes in plant cells. This book is a valuable source of information for postgraduate workers, although much of the material could be used in undergraduate courses.

Available in PDF, EPUB and Kindle. Book excerpt: It is now about 100 years since the chloroplast has been recognized as the site of photosynthesis in plant cells. The last 20 years have seen a striking increase in interest in the structure and function of the chloroplast. Hastened on by powerful new tools such as the electron microscope and the newer methods of isolation and analysis of chloroplasts, there is presently considerable experimental work on the properties of this organelle. In such a rapidly moving field and one which is reviewed systematically is various Annual Reviews, it is not possible to present a detailed critique of the prolific literature in a book of reasonable size. Rather the decision was made to sacrifice complete coverage of the field and to indicate general areas of investigation. In organization, problems here dealt with, are those concerned with the electron microscopy of chloroplast structure, development and conformation, genetic control of chloroplast development, characterization of some of the major components of the chloroplast and the biochemical properties of the chloroplast including the for mation of adenosine triphosphate and reduced pyridine nucleotide and the assim ilation of carbon dioxide into carbohydrate with subsequent conversion to second ary products. A historical outline on the general subject "Photosynthesis and the Chloroplast" has been included to place into proper perspective the rapid developments in the several areas covered in the book. I am particularly indebted to Dr. Roy E.
