Botany: A Lab Manual, Seventh Edition is mapped to match Botany: An Introduction to Plant Biology, Seventh Edition but is the perfect companion for any botany course. Packed with hands-on activities, it engages students and broadens their understanding of plant biology. Now in full color and a convenient lay-flat format, it provides detailed examination of plant structure, plant groups, genetics, classification, and more. Featuring additional case studies and image labelling activities, Botany: A Lab Manual is the clear choice for students digging into this exciting science.
Research in James Mauseth's lab centers on evolution of morphogenic mechanisms and structure. They use cacti as model organisms because the family contains a great amount of structural/developmental diversity and because the cactus genus Pereskia retains numerous relictual characters. Plants of Pereskia have hard woody stems and ordinary large leaves. From ancestors like this, morphogenic mechanisms have evolved into ones capable of controlling the differentiation of various types of highly modified wood, unusual types of cortex that have leaf-like features, and apical meristems that minimize the number of mitoses necessary to produce large plants. Because each evolutionary line in the family has undergone particular types of modification of the morphogenic mechanism, they can compare different types of differentiation of a particular tissue, each type controlled by homologous morphogenic mechanisms.
