Abstract

"Sekcja Struktury i Rozwoju Roślin została powołana w dniu 12 września 1973 r. podczas obrad 42. Zjazdu PTB w Krakowie jako Sekcja Anatomii, Cytologii i Embriologii Roślin. Jej przewodniczącą została prof. Maria Skalińska (Tab. 11.7.1), promotorka krakowskiej szkoły cytologii i embriologii roślin, w świecie nauki znana przede wszystkim z prac dotyczących cytogenetyki gatunków z rodzaju Aquilegia i ich mieszańców oraz eksperymentalnie uzyskanych poliploidów (Zemanek 2011)."

13. CHROMOSOME NUMBERS IN HIERACIUM (ASTERACEAE) FROM CENTRAL AND SOUTHEASTERN EUROPE VII.

Author

MUSIAŁ, KRYSTYNA and SZELĄG, ZBIGNIEW

Abstract

Chromosome numbers of 17 taxa of Hieracium s.str. from Bulgaria, Greece, Poland and Romania are specified and their metaphase plates are illustrated. Chromosome numbers are published for the first time for H. engleri R. Uechtr. (4x), H. kritschimanum Mattfeld & Zahn (3x), H. latifolium Link (3x), H. tephrosoma subsp. amaurocranum Zahn (5x), as well as five undescribed species belonging to the H. lachenalii agg. (3x), H. rohacsense agg. (4x), H. vagneri agg. (4x), H. vranjanum agg. (4x) and H. wiesbaurianum agg. (3x), and a new hybrid between H. caesium s.lat and H. umbellatum (4x). [ABSTRACT FROM AUTHOR]

14. IMMUNOLOCALIZATION OF PECTINS AND ARABINOGALACTAN PROTEINS IN YOUNG OVULES OF SELECTED AMPHIMICTIC AND APOMICTIC SPECIES OF THE ASTERACEAE FAMILY.

Author

Abstract

Cell wall components' especially arabinogalactan proteins (AGPs) and pectins as the source of signaling molecules active in cell-to-cell communication, are involved in many biological processes, including plant growth and development. Understanding the mechanisms of intercellular communication is particularly important in the context of reprogramming cell fate and transition from somatic to germline identity. The present study focuses on immunodetection of some pectic epitopes and AGPs in young ovules of selected Hieracium, Pilosella and Taraxacum species. The purpose of this research was to answer the questions: (1) whether the distribution of pectins and AGPs is related to the mode of reproduction and (2) whether their spatial and temporal distribution in young ovules may herald a later differentiation of the nutrient tissue present in the integument of mature ovules. We analyzed the localization of low and highly methyl-esterified pectins and AGP epitopes using monoclonal antibodies, i.e., LM19, LM20, JIM13, respectively. Our research found no significant differences in the localization of pectins and AGPs in young ovules of sexual and apomictic species, and the initial distribution pattern of these compounds did not appear to be related to the subsequent differentiation of the periendothelial nutrient zone. The presented findings may confirm the existence of a general developmental trend in the spatial and temporal distribution of pectins and AGPs during the maturation of ovules in angiosperms.

18. Chromosome numbers in hybrids between invasive and native Solidago (Asteraceae) species in Europe

Abstract

In Europe, two North American species, Solidago canadensis and S. gigantea hybridize with native S. virgaurea producing the hybrids: S. ×niederederi, a hybrid between S. canadensis and S. virgaurea, and S. ×snarskisii, a hybrid between S. gigantea and S. virgaurea. The morphological description of both hybrids has been well established in contrast to the data on chromosome numbers which were insufficiently recorded or missing. The diploids of S. ×niederederi have been recently reported from a few localities in Austria and Lithuania. In this study, we evidenced a triploid of S. ×snarskisii from one locality in Lithuania, as well as confirmed diploids in the progenies of S. ×niederederi collected in 23 new localities in Austria, Poland, Lithuania, and Latvia, based on chromosome counting.

33. Molecular, histological and embryological analysis of regenerants obtained during in vitro culture of immature embryos of apomictic Taraxacum belorussicum Val. N. Tikhom

Abstract

Dandelion as a model herbal plant has a wide application in analysis of genetic, molecular background of apomictic reproduction. Taraxacum belorussicum Val. N. Tikhom. is a triploid species belonging to Taraxacum sect. Palustria. As an obligatory apomictic plant it presents attractive experimental material for apomixis and somatic embryogenesis aspects. Here we present the preliminary studies showing direct organogenesis and genetic stability of the regenerants achieved during in vitro culture of dandelion along with their embryological analysis.
