Biotechnology and the domestication of forest trees.
Wood is one of the major renewable materials. To compensate for the ever-increasing demand for wood and to reduce pressure on native forests, more wood of higher quality will need to be produced on less land by planting highly productive trees. Biotechnology has shown great promise for forest tree improvement and over the past 10 years this field has flourished. Not only has the potential of tr...
متن کاملResponse to Comment on "Persistent effects of pre-Columbian plant domestication on Amazonian forest composition".
McMichael et al state that we overlooked the effects of post-Columbian human activities in shaping current floristic patterns in Amazonian forests. We formally show that post-Columbian human influences on Amazonian forests are indeed important, but they have played a smaller role when compared to the persistent effects of pre-Columbian human activities on current forest composition.
متن کاملComment on "Persistent effects of pre-Columbian plant domestication on Amazonian forest composition".
Levis et al (Research Articles, 3 March 2017, p. 925) concluded that pre-Columbian tree domestication has shaped present-day Amazonian forest composition. The study, however, downplays five centuries of human influence following European arrival to the Americas. We show that the effects of post-Columbian activities in Amazonia are likely to have played a larger role than pre-Columbian ones in s...
متن کاملFrom forest to field: perennial fruit crop domestication.
PREMISE OF THE STUDY Archaeological and genetic analyses of seed-propagated annual crops have greatly advanced our understanding of plant domestication and evolution. Comparatively little is known about perennial plant domestication, a relevant topic for understanding how genes and genomes evolve in long-lived species, and how perennials respond to selection pressures operating on a relatively ...
