Perspectives on Genetic Analysis of Plant Embryogenesis.

Embryogenesis plays a central role in the life cycle of flowering plants. Ever since the process of double fertilization was documented at the turn of the century, plant embryologists have attempted to characterize the cellular and biochemical changes that occur within developing seeds (Maheshwari, 1950; Raghavan, 1976). For many years, the emphasis was on comparative morphology and the analysi...

Special Section: Embryology of Flowering Plants

P. Maheshwari who served as Professor and Head of the Department of Botany, University of Delhi from 1950 to 1966 built a flourishing school of embryology which became internationally recognized. His colleagues and students have contributed significantly to all areas of embryology through integrative approaches. In memory of his birth centenary year, we have prepared this article that summarize...

A Manual of Experimental Embryology

Under this somewhat ambiguous title appears an excellent presentation of the reception given by European scientists to the Experiments and Observations published at Plattsburg in 1833. The accord given the work offers a striking example, indeed, a rare one, of how meritorious work can compensate for lack of renown on the part of the author. For though notice had been taken of some of Beaumont's...

Special Section: Embryology of Flowering Plants

Sexual reproduction in higher plants requires the development of a special cell protrusion, the so-called pollen tube, which is generated by the male gametophyte. Like other plant cells, the pollen tube contains a conspicuous cytoskeletal apparatus that regulates and promotes most of its biological functions, the most important of which is the transport of sperm cells. The study of the pollen t...
