A unique feature of plants is the fact that environmental factors play a crucial role in their development. In this course, molecular, cell biological, and physiological aspects of plant developmental processes will be discussed. We will cover several conceptual frameworks for the development of plant cell types and organs. The focus will be on how plant endogenous signals are directing plant organ development, how these signaling networks can be modified by environmental factors, and how such networks evolved. Different examples in the lectures, tutorials, and literature discussions will be used to illustrate how plants can adapt to their environment at the cellular, tissue, and whole plant levels by integrating environmental cues into developmental processes.lants can adapt at the cellular, tissue and whole plant level to their environment by integrating environmental cues into developmental processes.
