Although plants reproduce both sexually and asexually, sexual reproduction generates recombination and enables the species to adapt to changing environment. In angiosperms, the fl ower is the unit of sexual reproduction. However, in a few species, seeds develop without fertilization; this phenomenon is termed apomixis. Reproductive biology has direct relevance in many fundamental and applied areas of plant sciences. Reproduction is the basis of survival and sustenance of populations and species in natural habitats. Habitat degradation, overexploitation and climate change have threatened the sustainability of our biodiversity. The threat of species extinction is more pronounced in tropical countries such as Brazil, India, Malaysia, Indonesia and several others in South-East Asian where population pressure on forests and other natural resources has increased enormously in recent years. A large number of species have been pushed into the threatened status (rare, endangered and threatened category, RET species) as their populations have reduced markedly. Effective management of our biodiversity is going to be a major challenge in the coming decades. Unless suitable measures are taken, many of the threatened species would soon be extinct. According to many conservation biologists, an accelerating decline in world’s biodiversity as a result of human activity is leading to the sixth major extinction event on our planet. Reproductive failure, as a result of constraints in one or several reproductive events, is the driving force for species extinction. Therefore, a comprehensive knowledge on their reproductive biology is required for effective management, conservation and sustainable utilization of our biodiversity. In most of our crop plants, seeds and/or fruits are the economic products, and are the results of sexual reproduction. Reproductive events are susceptible to a range of environmental stresses that affect crop yields. Studies on reproductive ecology, therefore, have direct bearing not only for optimization of crop productivity but also on crop improvement through conventional and molecular approaches. vi Reproductive Biology of Plants In recent years, reproductive biology has gained prominence in University education at different levels because of its importance in a range of fundamental and applied areas of plant Sciences. In the light of the prevailing specialization and super-specialization, it is diffi cult to get an overview of recent advances made on various aspects of reproductive biology. This book is aimed at providing an overview of reproductive biology essentially of fl owering plants, although a few chapters on lower plants are also included. The chapters are written by recognized international specialists in their respective fi eld of research. The book will be useful to students, teachers and researchers in wider disciplines of botany, molecular biology, agri-horticulture, forestry, environmental biology, conservation biology, entomology and biotechnology. We would like to acknowledge ready cooperation of our contributors who have put in their efforts to ensure a high scientifi c quality to this book with up to date information. We wish to thank our publishers for their support and timely publication. K.G. Ramawat J.M. Mérillon K.R. Shivanna Contents Preface v 1. Reproduction in Microalgae 1 Romain Gastineau, Nikolai A.

Hallegraeff,3 Ian Probert4 and Jean-Luc Mouget1,* ABSTRACT Algae have traditionally been included in the group Cryptogamae (‘hidden reproduction’), as opposed to Phanerogamae or Spermatophyta, the Seed Plants. Cryptogamae encompassed both macro- and microalgae, lichens, mosses, and ferns, and have also been referred to as ’Thallophyta’, ’non-vascular plants’, ‘spore plants’, seedless or fl owerless plants, depending on the criteria used for classifi cation. Microalgae have long been considered among the more primitive and less important organisms representing the plant-like characters of autotrophy and immobility. Reproduction in macroalgae was only observed in the 18th century, but the ability of microalgae to reproduce sexually was not demonstrated until the 19th century in microscopic green fi lamentous algae. In this chapter, we summarise up-to-date information on sexual reproduction in three major groups of 1 LUNAM Université, FR CNRS 3473 IUML, MMS (Mer, Molécules, Santé), Université du Maine, Avenue Olivier Messiaen, 72085 Le
