"Botany: An Introduction to Plant Biology continues to set the standard for the fundamentals of plant science. No botany text better connects structure to function and does so with higher quality art and imagery. Combining strong scientific grounding with an approachable writing style, Botany teaches and engages. The essentials to a foundational understanding of plant science are all there, including structure, genetics and evolution, physiology and development, and ecology. The text continues to lead with the latest material on molecular biology, plant biotechnology, and the most recent coverage of taxonomy and phylogeny of plants to keep students on the forefront of cutting-edge botanical research"--

This book provides up-to-date knowledge of root biology. Most plants have roots, which anchor the plant in the soil and physically support the above-ground parts of the plant. In addition, roots absorb water and nutrients from the soil and transport this to the shoot. Roots grow by cell proliferation in the meristem in the root tip. The cells differentiate into the epidermis, cortex, and stele. Water and nutrients are absorbed through the cell membrane of the epidermis and are transported to the above-ground parts via xylem vessels. The root growth and functions are affected by various abiotic and biotic conditions, such as levels of water, salt, acid stresses, and presence of soil diseases. However, some beneficial microorganisms such as rhizobia and mycorrhizal fungi help plant growth.

Octobre 1248, Ibn Baytar le plus réputé des pharmacologues et herboristes des hôpitaux du Caire s'apprête à se mettre en route pour regagner Damas où Saleh Ayoub, sultan d'Egypte et de Syrie, neveu de Saladin, doit séjourner. Le sultan malade est inquiet : les Mongols dévastent Bagdad et l'Occident lance la IXe croisade. A Damas, il veut surtout confier à Setti Hasifa, connue sous le nom de La botaniste de Damas le Traité des Simples et des aliments, auquel il travaille depuis quarante ans et qui rassemble l'ensemble des connaissances en botanique et en pharmacologie du moment. A sa mort, Hasifa, désormais en possession de cet imposant ouvrage relié de cuir rouge, l'emportera à Venise dans l'exil de sa famille damascène chassée de Syrie par les hordes des Mongols. Etonnant destin que celui de ce Traité des Simples ! Rapporté au Maghreb, puis, dans quelques bibliothèques d'Occident, il sera copié, étudié, traduit dans le monde entier et reste toujours l'ouvrage de référence pour tout travail de botanique, d'herboristerie et de pharmacologie. De nouveau, l'auteur, qui a déjà publié à nos éditions et avec grand succès La Botaniste de Damas, nous donne à lire une page passionnée et passionnante de l'incessant combat qui se mène entre le savoir et la barbarie.
