Plant Developmental Biology

📘 Plant Developmental Biology (2026–2027 Edition)

Plant Developmental Biology (2026–2027 Edition) is a comprehensive academic textbook designed for BS students, researchers, and educators in botany, plant sciences, genetics, and biotechnology. This book explains how plants grow, differentiate, and develop from a single fertilized cell into complex multicellular organisms with specialized tissues and organs.

This book integrates classical developmental biology with modern molecular and genetic approaches. It explores the role of meristems, hormones, genes, and environmental signals in controlling plant growth, organ formation, reproduction, and adaptation to environmental conditions.

🌱 Unit 1: Introduction to Plant Development
• Historical perspectives and key concepts in plant development

• Role of plant hormones in developmental processes
• Environmental influence on plant growth and development
• Experimental approaches in plant developmental biology

🌾 Unit 2: Embryogenesis
• Fertilization and formation of the zygote
• Early embryonic pattern formation
• Apical–basal and radial organization in embryos
• Development and function of the suspensor
