In response to enormous recent advances, particularly in molecular biology, the authors have revised their warmly received work. This new edition includes updates on seed development, gene expression, dormancy, and other subjects. It will serve as the field's standard textbook and reference source for many years to come.

This book introduces the reader to the exciting new field of plant philosophy and takes it in a new direction to ask: what does it mean to say that plants are sexed? Do 'male' and 'female' really mean the same when applied to humans, trees, fungi and algae? Are the zoological categories of sex really adequate for understanding the - uniquely 'dibiontic' - life cycle of plants? Vegetal Sex addresses these questions through a detailed analysis of major moments in the history of plant sex, from Aristotle to the modern day. Tracing the transformations in the analogy between animals and plants that characterize this history, it shows how the analogy still functions in contemporary botany and asks: what would a non-zoocentric, plant-centred philosophy of vegetal sex be like? By showing how philosophy and botany have been and still are inextricably entwined, Vegetal Sex allows us to think vegetal being and, perhaps, to recognize the vegetal in us all.

Cell Signaling Pathways in Development, Volume 149 in the Current Topics in Developmental Biology series, highlights new advances in the field, with this new volume presenting interesting chapters on a variety of topics, including Ephrin signaling, Cell signaling to the extracellular matrix, Signaling by TGF-b superfamily members, Hedgehog signaling, Parallels in signaling during development and regeneration, Hippo signaling, Wnt/PCP signaling, Signaling oscillations in presomitic mesoderm, FGFs/RTKs subcellular signaling compartments, and Signaling dynamics.

This science reader introduces students to the life cycle of plants. With bright, engaging images, it details the parts of plants and how plants grow and thrive. With easy-to-read text, this book teaches students important scientific concepts and vocabulary terms including habitat, adapt, and the parts of plants. Aligned to state and national standards, the book contains nonfiction text features like an index, a glossary, captions, and bold font to keep students connected to the text. A hands-on science experiment helps students apply what they have learned and develops critical thinking skills.

Wnt Signaling in Development and Disease, Volume 153 in the Current Topics in Developmental Biology series, highlights new advances in the field, with this new volume presenting interesting chapter on topics such as The cell biology of Wnt gradient formation, Approaches to visualize and trace Wnt signaling in vitro and in vivo, WNT signaling and the regulation of pluripotency, Wnt/Frizzled signaling in stem cells in development and cancer, Wnt signaling in hydra development and regeneration, Wnt signaling in whole body regeneration, Role of planar cell polarity and Wnt signaling in left-right asymmetry, Wnt signaling in axial progenitors, and more. Other chapters cover Wnt signaling in Xenopus neural development, Wnt signaling in hematopoietic stem cell development, Wnt signaling and the maintenance and regeneration of the gut epithelium, Wnt signaling in the skeleton as a basis for Wnt-based regenerative medicine, and Non-canonical Wnt5a-Ror signaling: Insights from human congenital disorders and cancer.
