Genetics and Genomics of Forest Trees
Forest tree genetics and genomics are advancing at an accelerated rate, thanks to recent developments in high-throughput, next-generation sequencing capabilities, and novel biostatistical tools. Population and landscape genetics and genomics have seen the rise of new approaches implemented in large-scale studies that employ the use of genome-wide sampling. Such studies have started to discern the dynamics of neutral and adaptive variation in nature and the processes that underlie spatially explicit patterns of genetic and genomic variation in nature. The continuous development of genetic maps in forest trees and the expansion of QTL and association mapping approaches contribute to the unravelling of the genotype-phenotype relationship and lead to marker-assisted and genome-wide selection. However, major challenges lie ahead. Recent literature suggests that species demography and genetic diversity have been affected both by climatic oscillations and anthropogenically induced stresses in a way calls into question the possibility of future adaptation. Moreover, the pace of contemporary environmental change presents a great challenge to forest tree populations and their ability to adapt, taking into consideration their life history characteristics. Several questions emerge that include, but are not limited to, the interpretation of forest tree genome surveillance and their structural/functional properties, the adaptive and neutral processes that have shaped forest tree genomes, the analysis of phenotypic traits relevant to adaptation (especially adaptation under contemporary climate change), the link between epigenetics/epigenomics and phenotype/genotype, and the use of genetics/genomics as well as genetic monitoring to advance conservation priorities.
Tropical Forest Genetics

This book is intended to provide information on fundamental genetic processes in tropical forests. It is based on lecture notes by the authors prepared for po- graduate students, mainly from tropical countries, of the M.Sc. course “Tropical and International Forestry”at the Faculty of Forest Sciences and Forest Ecology, Georg August University Göttingen, Germany. The intended readership is s- dents, researchers and practitioners interested in the genetic variation of species, in particular forest trees, living in complex forest ecosystems in the tropics. Particular emphasis is placed on the human impact on forest genetic resources in the tropics. Readers should be familiar with basics of classical and molecular genetics such as the structure and function of DNA (double-helix structure, repli- tion), polypeptide synthesis (transcription and translation), and the transm- sion of genetic information during sexual reproduction (“Mendel’s rules”). This knowledge is easily available from recently published genetics textbooks; we recommend the book by Griffiths et al. (2000). The development of biochemical and molecular marker techniques and their application to species of tropical forests have greatly improved our kno- edge of genetic variation patterns of “wild”plants in the tropics during the last two decades. Many examples in this book are based on gene marker techniques.
