Populusspp. Family: Salicaceae Aspen
Populus spp. Family: Salicaceae Aspen Aspen (the genus Populus) is composed of 35 species which contain the cottonwoods and poplars. Species in this group are native to Eurasia/north Africa [25], Central America [2] and North America [8]. All species look alike microscopically. The word populus is the classical Latin name for the poplar tree. Populus grandidentata-American aspen, aspen, bigtooth aspen, Canadian poplar, large poplar, largetooth aspen, large-toothed poplar, poplar, white poplar Populus tremuloides-American aspen, American poplar, aspen, aspen poplar, golden aspen, golden trembling aspen, leaf aspen, mountain aspen, poplar, popple, quaking asp, quaking aspen, quiver-leaf, trembling aspen, trembling poplar, Vancouver aspen, white poplar Distribution Quaking aspen ranges from Alaska through Canada and into the northeastern and western United States. In North America, it occurs as far south as central Mexico at elevations where moisture is adequate and summers are sufficiently cool. The more restricted range of bigtooth aspen includes southern Canada and the northern United States, from the Atlantic coast west to the prairie. The Tree Aspens can reproduce sexually, yielding seeds, or asexually, producing suckers (clones) from their root system. In some cases, a stand could then be composed of only one individual, genetically, and could be many years old and cover 100 acres (40 hectares) or more. Most aspen stands are a mosaic of several clones. Aspen can reach heights of 120 ft (48 m), with a diameter of 4 ft (1.6 m). Aspen trunks can be quite cylindrical, with little taper and few limbs for most of their length. They also can be very crooked or contorted, due to genetic variability. -

Poplars and Willows: Trees for Society and the Environment / Edited by J.G
Poplars and Willows Trees for Society and the Environment This volume is respectfully dedicated to the memory of Victor Steenackers. Vic, as he was known to his friends, was born in Weelde, Belgium, in 1928. His life was devoted to his family – his wife, Joanna, his 9 children and his 23 grandchildren. His career was devoted to the study and improve- ment of poplars, particularly through poplar breeding. As Director of the Poplar Research Institute at Geraardsbergen, Belgium, he pursued a lifelong scientific interest in poplars and encouraged others to share his passion. As a member of the Executive Committee of the International Poplar Commission for many years, and as its Chair from 1988 to 2000, he was a much-loved mentor and powerful advocate, spreading scientific knowledge of poplars and willows worldwide throughout the many member countries of the IPC. This book is in many ways part of the legacy of Vic Steenackers, many of its contributing authors having learned from his guidance and dedication. Vic Steenackers passed away at Aalst, Belgium, in August 2010, but his work is carried on by others, including mem- bers of his family.

Populus Alba White Poplar1 Edward F
Fact Sheet ST-499 October 1994 Populus alba White Poplar1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION White Poplar is a fast-growing, deciduous tree which reaches 60 to 100 feet in height with a 40 to 50-foot-spread and makes a nice shade tree, although it is considered short-lived (Fig. 1). The dark green, lobed leaves have a fuzzy, white underside which gives the tree a sparkling effect when breezes stir the leaves. These leaves are totally covered with this white fuzz when they are young and first open. The fall color is pale yellow. The flowers appear before the leaves in spring but are not showy, and are followed by tiny, fuzzy seedpods which contain numerous seeds. It is the white trunk and bark of white poplar which is particularly striking, along with the beautiful two-toned leaves. The bark stays smooth and white until very old when it can become ridged and furrowed. The wood of White Poplar is fairly brittle and subject to breakage in storms and the soft bark is subject to injury from vandals. Leaves often drop from the tree beginning in summer and continue dropping through the fall. Figure 1. Middle-aged White Poplar.

Populus: A Premier Pioneer System for Plant Genomics 1 1 Populus: A Premier Pioneer System for Plant Genomics Stephen P. DiFazio,1,a,* Gancho T. Slavov 1,b and Chandrashekhar P. Joshi 2 ABSTRACT The genus Populus has emerged as one of the premier systems for studying multiple aspects of tree biology, combining diverse ecological characteristics, a suite of hybridization complexes in natural systems, an extensive toolbox of genetic and genomic tools, and biological characteristics that facilitate experimental manipulation. Here we review some of the salient biological characteristics that have made this genus such a popular object of study. We begin with the taxonomic status of Populus, which is now a subject of ongoing debate, though it is becoming increasingly clear that molecular phylogenies are accumulating. We also cover some of the life history traits that characterize the genus, including the pioneer habit, long-distance pollen and seed dispersal, and extensive vegetative propagation. In keeping with the focus of this book, we highlight the genetic diversity of the genus, including patterns of differentiation among populations, inbreeding, nucleotide diversity, and linkage disequilibrium for species from the major commercially- important sections of the genus. We conclude with an overview of the extent and rapid spread of global Populus culture, which is a testimony to the growing economic importance of this fascinating genus.

The Evolutionary Fate of Rpl32 and Rps16 Losses in the Euphorbia Schimperi (Euphorbiaceae) Plastome Aldanah A
www.nature.com/scientificreports OPEN The evolutionary fate of rpl32 and rps16 losses in the Euphorbia schimperi (Euphorbiaceae) plastome Aldanah A. Alqahtani1,2* & Robert K. Jansen1,3 Gene transfers from mitochondria and plastids to the nucleus are an important process in the evolution of the eukaryotic cell. Plastid (pt) gene losses have been documented in multiple angiosperm lineages and are often associated with functional transfers to the nucleus or substitutions by duplicated nuclear genes targeted to both the plastid and mitochondrion. The plastid genome sequence of Euphorbia schimperi was assembled and three major genomic changes were detected, the complete loss of rpl32 and pseudogenization of rps16 and infA. The nuclear transcriptome of E. schimperi was sequenced to investigate the transfer/substitution of the rpl32 and rps16 genes to the nucleus. Transfer of plastid-encoded rpl32 to the nucleus was identifed previously in three families of Malpighiales, Rhizophoraceae, Salicaceae and Passiforaceae. An E. schimperi transcript of pt SOD-1- RPL32 confrmed that the transfer in Euphorbiaceae is similar to other Malpighiales indicating that it occurred early in the divergence of the order. Ribosomal protein S16 (rps16) is encoded in the plastome in most angiosperms but not in Salicaceae and Passiforaceae. Substitution of the E. schimperi pt rps16 was likely due to a duplication of nuclear-encoded mitochondrial-targeted rps16 resulting in copies dually targeted to the mitochondrion and plastid. Sequences of RPS16-1 and RPS16-2 in the three families of Malpighiales (Salicaceae, Passiforaceae and Euphorbiaceae) have high sequence identity suggesting that the substitution event dates to the early divergence within Malpighiales. -

The Development of Populus Alba L. and Populus Tremula L. Species Specific Molecular Markers Based on 5S Rdna Non-Transcribed Spacer Polymorphism
Communication The Development of Populus alba L. and Populus tremula L. Species Specific Molecular Markers Based on 5S rDNA Non-Transcribed Spacer Polymorphism Oleg S. Alexandrov * and Gennady I. Karlov Laboratory of Plant Cell Engineering, All-Russia Research Institute of Agricultural Biotechnology, Timiryazevskaya 42, Moscow 127550, Russia; [email protected] * Correspondence: [email protected]; Tel.: +7-499-976-6544 Received: 1 November 2019; Accepted: 26 November 2019; Published: 1 December 2019 Abstract: The Populus L. genus includes tree species that are botanically grouped into several sections. This species successfully hybridizes both in the same section and among other sections. Poplar hybridization widely occurs in nature and in variety breeding. Therefore, the development of poplar species’ specific molecular markers is very important. The effective markers for trees of the Aigeiros Duby section have recently been developed using the polymorphism of 5S rDNA non-transcribed spacers (NTSs). In this article, 5S rDNA NTS-based markers were designed for several species of the Leuce Duby section. The alb9 marker amplifies one fragment with the DNA matrix of P. alba and P. × canescens (natural hybrid P. alba P. tremula). The alb2 marker works the same way, except for the × case with Populus bolleana. In this case, the amplification of three fragments was observed. The tremu1 marker amplification was detected with the DNA matrix of P. tremula and P. canescens. Thus, the × developed markers may be applied as a useful tool for P. alba, P. tremula, P. canescens, and P. bolleana × identification in various areas of plant science such as botany, dendrology, genetics of populations, variety breeding, etc.
