Аннотация: The results summarize many years of karyological and cytogenetic studies of conifers from the boreal zone, done at the Sukachev Forest Institute. The species under study belong to four genera of the family Pinaceae: Larix (larch), Pinus (pine), Picea (spruce), and Abies (fir). Overall, the research covers more than 100 populations and habitats of the species from these genera. The study concerns species growing under both optimal and marginal conditions. The studies of the family Cupressaceae have been initiated. A special attention is given to conifers growing on bogs and in planted forests.

Аннотация: Chromosome numbers for some species of Central Asia steppe shrubs are given: Rhamnus erythroxylon Pall. (Rhamnaceae), Caragana buriatica Peschk. (Fabaceae), Amygdalus pedunculata Pall., Armeniaca sibirica (L.) Lam. (Rosaceae), Atraphaxis pungens (Bieb.) Jaub. et Spach, and A. frutescens (L.) C. Koch (Polygonaceae). Chromosome numbers of some species were determined for the first time. A comparative analysis of adaptive properties of polyploidy and diploid species has been conducted. It was established that natural polyploids are more adaptive to existence in extreme conditions. They possess a high potential for survival and are characterized by a higher level of intraspecific polymorphism, abundant flowering and fruitification, ability to propagate both via generative and vegetative means, and high seed germination.

Аннотация: Data are presented on the karyotype structure of the Siberian fir (Abies sibirica Ledeb.) from five populations of the Central Siberia. The chromosome set (2n = 24) contains seven pairs of metacentric (I-VII), four pairs of submetacentric (VIII and X-XII), and one pair of intercentric (IX) chromosomes. The morphometric parameters of the identified chromosome groups had close values in the studied populations. The variation coefficients of chromosomal parameters of the Siberian fir correspond to very low and low variability. The intraspecific chromosome polymorphism of the Siberian fir is connected mainly to variations in the number and peculiarities of the nucleolar organizing regions of chromosomes. In the territory with technogenic loading, a wide spectrum of genomic mutations of the mixoploidy type was observed in the seed off-spring of the Siberian fir; triploid seedlings, as well as rare cases of somatic reduction of chromosomes, were revealed.

Аннотация: Обобщены результаты кариологических и цитогенетических исследований в популяциях видов хвойных семейств Pinaceae и Cupressaceae из экстремальных условий произрастания. У хвойных, произрастающих у южной и северной границ ареалов на экологическом пределе распространения, в антропогенно нарушенных экосистемах, в условиях интродукции, выявлена хромосомная изменчивость, обнаружены геномные и хромосомные мутации различного типа. Отмечены высокая частота изменений числа хромосом (миксоплоидия, анеуплоидия и полиплоидия) и их морфологии. Найдены различные типы хромосомных аномалий (кольцевые и полицентрические хромосомы, фрагменты, множественные хромосомные аномалии), агглютинация хромосом, появление В-хромосом, нарушения митоза и мейоза. С использованием классических методов и флуоресцентной гибридизации in situ (FISH) проведены исследования полиморфизма нуклеолярных районов хромосом, выявлены особенности локусов генов 5S и 45S рибосомной РНК.
Results of karyological and cytogenetical studies in populations of conifer species of Pinaceae and Cupressaceae families from extreme conditions are summarized. In conifers growing in southern and northern borders of areas, on ecological limits of distribution, in anthropogenically disturbed ecosystems, at the introduction, chromosome variability is revealed. A high frequency of changes in the number of chromosomes (mixoploidy, aneuploidy and polyploidy) and their morphology were noted. Different types of chromosome anomalies (ring and polycentric chromosomes, fragments, multiple chromosome irregularities), B-chromosomes occurrence, irregularities of mitosis and meiosis are found. Using classical methods and fluorescent in situ hybridization (FISH), studies of the polymorphism of the nucleolar regions of chromosomes were carried out, and features of the loci of the 5S and 45S ribosomal RNA genes were revealed.
