Human life intimately depends on plants for food, biomaterials, health, energy, and a
sustainable environment. Various plants have been genetically improved mostly through …

Perennial species in the boreal and temperate regions are subject to extreme annual
variations in light and temperature. They precisely adapt to seasonal changes by …

Plant migration and gene flow from genetically modified or exotic trees to nearby lands or by
crossing with wild relatives is a major public and regulatory concern. Many genetic …

The spread of transgenes and exotic germplasm from planted crops into wild or feral species
is a difficult problem for public and regulatory acceptance of genetically engineered plants …

The role of the floral homeotic gene AGAMOUS (AG) and its close homologues in
development of anemophilous, unisexual catkins has not previously been studied. We …

Genetically improved forest reproductive materials are now widely accessible in many
European countries due to decades of continuous breeding efforts. Tree breeding does not …

The central floral development gene LEAFY (LFY), whose mutation leads to striking changes
in flowering and often sterility, is commonly expressed in non-floral structures; however, its …

A considerable body of research exists concerning the development of technologies to
engineer sterility in forest trees. The primary driver for this work has been to mitigate …

Key message Overexpression of the poplar PP2C protein phosphatase gene PtrHAB2
resulted in increased tree height and altered leaf morphology and phyllotaxy, implicating …

During the last several decades, a number of transgenic or genetically modified tree
varieties with enhanced characteristics and new traits have been produced. These trees …
