Emerging Model Systems in Plant Biology: Poplar (Populus) as A Model Forest Tree

Biochar as a Substitute for Vermiculite in Potting Mix for Hybrid Poplar

“…The clone 'NM6' is a fast-rooting hybrid which is easy to clonally propagate [23] and is expected to be representative of hybrid poplars utilized in the region. While unrooted cuttings are typically used for field planting, greenhouse production of the cloned plants is often used in the initial phase of scaling up a new selection for commercial use; in addition, poplars serve as model plants for woody species in general [24,25], many of which are reared in the greenhouse before being planted in the field.…”

The obscure events contributing to the evolution of an incipient sex chromosome in Populus: a retrospective working hypothesis

“…By 1924, it became clear that the base chromosome number in Populus was 19 (Harrison 1924). Since then, examination by various scientists has revealed that all Populus species generally appear as diploids with 2n038 (Smith 1943), with occasional cases of triploid or tetraploid genets arising naturally in various species though more often reported in members of the Leuce subgenera and in interspecific crosses (Einspahr et al 1963;Bradshaw et al 2000). Analysis of the assembled genome revealed that the chromosomal structure in modern Populus arose from an ancient whole-genome duplication event known as "salicoid" duplication ( Fig.…”

Somaclonal variations as a mean for obtaining regenerants with different growth rates in poplar (<i>Populus × berolinensis</i> Dipp.)

“…Genetic transformation of poplar draws attention for growth fastening [6,7], decrease of lignin content [8][9][10], and increase of the resistance to pests [11]. This transformation is facilitated due to the fact that the genome of poplar is fully sequenced in recent time [12,13] and now it is considered as a model for the study of molecular biology of woody plants [14]. However, a real practical use of transgenic poplars is hindered from the apprehension of unregulated carrying over their pollen and seeds and possibility for rise of transgenic plants in natural forests [15].…”
