Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and gr...

The avocado industry is evolving rapidly. Avocado production has almost doubled recently, with significant expansion in areas planted, especially in Latin America, but also in Africa and Asia. Moreover, the global demand for avocado keeps on growing. The Avocado, 3rd edition is a unique and comprehensive source of information for avocado researchers, and covers everything from the history and distribution, novel agronomic practices, ecological and climatic requirements, and emerging diseas...

Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resu...
