Trees of the genus Populus (poplars) are prominent forest tree species in temperate regions of the northern hemisphere and have been used as experimental organisms to understand various aspects of tree biology for over three decades. Rapid advances in generating genomic, bioinformatic, and functional ...

In this review, we address recent progress in the molecular calendar of fruit trees and the molecular models Arabidopsis and Populus, with a focus on epigenetic-related mechanisms, which provide the regulatory plasticity, reversibility and specificity required for seasonal phenological processes. View ...
The poplar tree falls in the genus Populus family, which consists of approximately 35 tree types. Poplar is a fast growing tree planted for farm wind breaks and to quickly reforest damaged areas.Poplar trees produce a lot of leaves which can result in a lot of yard work during the ...
The Oak genus,Quercus, includes some of our most important native hardwoods, and are some of the most-recognized trees.We’ve photographed over twenty species of Oaks, Chinkapins and Beeches at the Morton Arboretum, as well as the State of Illinois Millennium Tree, and another Bur Oak that...
The genusCinnamomumbelongs to the family Laureaceae and consists of 250evergreen treesand shrubs distributed in Southeast Asia, China, and Australia. Many species of the genus are economically important species that have been used for timber production, as spices, and for medical purposes. Some of...
Fig trees, plants of the genusFicus, are akeystone speciesin many ecosystems and are found on every continent, with the exception of Antartica. There are 755 species of fig identified and an estimated 1300–2600fig waspspecies in existence. Most fig trees are pollinated by the fig wasps, an...
Abstract Nearly all species of the genus Populus are dioecious, i.e., form male and female flowers on separate individuals. However, bisexual poplar can occasionally be found under natural conditions or during the breeding process. According to the XX/XY model of sex determination, "supermale"...
