A progeny of 130 F1 individuals of an interspecific cross between Populus tremula L. and Populus tremuloides Michx. was used for genetic mapping of linkage group XIX with SSR markers based on the Populus trichocarpa Torr. & A. Gray genome sequence. Several fully sex-linked SSR markers were identified and mapped to a central position on the male P. tremuloides map of linkage group XIX. For the SSR markers tested here, the position on the assembled P. trichocarpa genome sequence is known, allowing sex-linked markers to be assigned to the central region of scaffold/chromosome 19 of P. trichocarpa. The sex linkage of the SSR markers was validated in other P. tremula × P. tremuloides crosses and also tested in Populus alba L. and Populus nigra L.

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.

Bark Structure

The development of bark structure of Quercus robur L., Ulmus glabra Huds., Populus tremula L. and Betula pendula Roth is being described. Profound structural changes can be observed during the first years after secondary growth has started. In all four species the epidermis is replaced by a periderm, the cortex shows intensive dilatation growth, and the groups of primary bark fibres are pushed apart. The collapse of sieve tube members starts with the second year. With proceeding secondary growth, the specific formation of sclerenchymatic tissue, especially sclereids, and the dilatation growth are processes which strongly affect the bark structure of Quercus robur, Populus tremula and Betula pendula. In addition, wide, fused phloem rays develop in Quercus robur. The structure of Ulmus glabra bark is affected by the formation of phloem fibre-/sclereid-like cells and mucilage cells and by dilatation growth. The histological pattern of Ulmus glabra bark stabilises to a great extent after the first few years, the other barks investigated show further developmental processes over many years. In all species the formation of a rhytidome is the last distinct modification of bark structure.
