This book provides insight into the biology and genomics of the genus Boswellia (family Burseraceae), a natural resource used for the production of frankincense, an oleo-gum resin. The Boswellia species are ecologically, medicinally, commercially and culturally important. Significantly contributing to the paucity of comprehensive literature on this genus, this volume provides a detailed discussion on the genomics, physiology and ecology of Boswellia. The chapters cover a wide range of topics, including taxonomy, distribution, genetic diversity and microbiology. The production process of frankincense and its impact on the species are presented as well. In light of the recent decline of various Boswellia populations, species propagation and conservation are discussed. Plant scholars, ecologists and conservation biologists will find this book to be an important and informative reference.

This book highlights the advances in essential oil research, from the plant physiology perspective to large-scale production, including bioanalytical methods and industrial applications. The book is divided into 4 sections. The first one is focused on essential oil composition and why plants produce these compounds that have been used by humans since ancient times. Part 2 presents an update on the use of essential oils in various areas, including food and pharma industries as well as agriculture. In part 3 readers will find new trends in bioanalytical methods. Lastly, part 4 presents a number of approaches to increase essential oil production, such as in vitro and hairy root culture, metabolic engineering and biotechnology. Altogether, this volume offers a comprehensive look at what researchers have been doing over the last years to better understand these compounds and how to explore them for the benefit of the society.

Deserts appear very fascinating during our short visits. However, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. The editor of this book was born and brought up in the Great Indian Desert, and has spent much of his life studying the growth and metabolism of desert plants. It is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. It has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. In this book, I have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. The scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. Therefore, there are chapters devoted to medicinal plants (Chap. 1), halophytes (Chaps. 13, 14), and fruit plants (Chaps. 17, 20). Desert plants have a unique reproductive biology (Chaps. 9–11), well-adapted eco-physiological and anatomical charact- istics (Chap. 7), and specialised metabolism and survival abilities. These plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (Chaps. 18–20).

The genus Bursera covers a vast area in the New World, extending from the southwestern part of the United States through México, Central and South America, and into the Caribbean Islands. Bursera has been embedded in the folklore of the Americas for its colorful exfoliation and for its aromatic gum resin known as copal since the Aztec and Inca periods. The resounding similarities of its use in medicine and incense make Bursera the Frankincense of the Americas. This book is a guide to growing, cultivating, and exhibiting Bursera, with the primary objective to preserve these hidden jewels of the New World through horticulture. The scientific classification of Bursera is put into context with its horticulture for a holistic understanding of the genus in habitat and in cultivation. It is written to be a reference book containing all 105 known species with their taxa, including descriptions, illustrations, photos of habitat and cultivated plants, with specificity to enable the reader to identify the species.

Although the unique flora of the Socotra Archipelago with its high degree of endemism has received much attention recently, little information is available on the vegetation and related ecological aspects. Based on their extensive field experience of the region, the authors have assimilated a vast amount of knowledge to produce this book, which gives a detailed insight into the plant ecology of Socotra, designated as a World Heritage Site by UNESCO in 2008. The book is divided into seven chapters. After a brief introduction and overviews of important abiotic features, various aspects of the vascular flora are presented in Chapter 4, together with accounts of the bryophyte and lichen flora. Ecology and adaptive strategies of the plants are dealt with in Chapter 5, and Chapter 6 gives a concise description of the main vegetation units. Finally, important management issues of the vegetation are discussed, an essential topic to ensure preservation of the natural heritage of the archipelago.
