Preface

This book gathers the state of the art of several aspects of citrus research. It consists of eleven chapters grouped into three sections: "Citrus Physiology and Production Technology", "Citrus Pests and Disease", and "Citrus in Human Health".

The first section discusses aspects of physiology and management of citrus production. Chapter 1 provides a review of world citrus production over the last five years. Chapter 2 examines different abiotic stresses in citrus crops and strategies for mitigating them in citrus production. Chapter 3 discusses citrus polyembryony, a relevant theme regarding citrus rootstocks. Chapter 4 discusses the degreening of citrus fruits and its effect on postharvest quality. Chapter 5 reviews citrus mineral nutrition and its consequences for both production and human health.

The second section addresses citrus pests and disease aspects. Chapter 6 reviews the main citrus diseases caused by viruses and viroids. Chapter 7 examines the quorum quenching mechanism to control citrus bacterial diseases. Chapter 8 discusses citrus-sucking and chewing insect pests.

The last section discusses the use of citrus in human health. Chapter 9 highlights the benefits of citrus consumption on human health. Chapter 10 discusses citrus polyphenols as strategies to overcome multidrug resistance. Finally, Chapter 11 addresses the use of citrus essential oils and citrus terpenes loaded in nanocarriers for treating skin diseases and for transdermal drug release.
