Cellular and Molecular Biology of Plant Seed DevelopmentPaperback, 6 December 2010

The beginnings of human civili zation can be traced back to the time, ne- ly 12,000 years ago, when th e early humans gradually ch anged from a life of hunting and gathering food, to producing food. This beginning of pri- tive agriculture ensured a dependable supply of food, and fostered the living together of people in groups and the development of s o c i e ty. During th is time, plant s e e ds were recognized a s a valuable s o ur c e of food and nutrition, and began to be used for growing plants for food. Ever s i n c e, plant seeds have played an important role in the development of the human civilization . Even today, s e e ds of a few crop s p e c i e s, s uc h as the cereals and legume s, are the primary s o u r c e of most human food, and the predominant commodity in international agriculture. Owing to their great importance as food for human s and in international trade, seeds have been a favorite object of s t u d y by developmental biologists and physiologi sts, nutritionist s and chem i sts . A wealth of useful information i s available on th e biology of seed s .
