This volume is the second in the series on 'Higher Plants', otherwise termed Phanerogam or Spermatophyte. The earlier volume, 1A, covered several taxa of Phanerogams and one of Bryophyte. A concurrent series (volume 2A, 2B and so on) cover the lower groups, represented by Algae, Fungi, Bryophytes and Lichens. Bryophyte, because of its importance in evolution of seed plants vis-a-vis higher groups, has been included in both volumes. The present volume includes articles dealing with certain fundamental issues of genomics as well as phylogeny and evolution of certain economic agricultural and medicinal crops. Of these, economic crops include coffee, coconut and papaya; medicinals cover Artemisia and Costus; fodder and agricultural crops include Phleum, Lolium and Triticale; horticultural species include Orchis and Allium and forest plant is represented by Populus species. In general, this volume contains discussions on molecular patters of basic angiosperms as well as genomics and phylogeny of different families.

Vegetables serve as an essential source of vital nutrients, including dietary fibers, minerals, antioxidants, and vitamins. The growing awareness of their medicinal and nutritional value has led to increased production worldwide, with China currently ranked as the top producer, at approximately 237 million tons. India's vegetable production for the year 2009-10 was approximately 90 million tons. Although pesticides can be valuable tools in sustainable vegetable production, their irresponsible use often poses hazards to producers, consumers, and the environment. Furthermore, their excessive use can lead to pest and disease resistance, as well as the suppression of natural biological control mechanisms. This book aims to promote the integration of appropriate chemical, cultural, physical, genetic, and biological technologies into IPM strategies for vegetable crop protection.
