“…For nuclear DNA content measurements, 8-23 plants per accession, depending on availability, were used. Young leaves were collected from plants grown in a growth chamber and samples for flow cytometric analysis were prepared as previously described [72] using-for nuclei isolation-Galbraith's buffer [73], supplemented with 1% (w/v) polyvinylpyrrolidone (PVP-10, MW 10,000; Sigma-Aldrich, St. Louis, USA), ribonuclease A (RNase A, 50 µg mL −1 ; Sigma-Aldrich), and propidium iodide (PI, 50 µg mL −1 ; Sigma-Aldrich). Solanum lycopersicum L. 'Stupicke' (2C = 1.96 pg; [74]) were used as an internal standard for D. glochidiatus, D. littoralis, O. daucorlaya, and T. arvensis, while for the remaining accessions, Petunia hybrida Vilm.…”

Background The genus Daucus (Apiaceae) comprises about 40 wild species and the cultivated carrot, a crop of great economic and nutritional importance. The rich genetic diversity of wild Daucus species makes them a valuable gene pool for carrot improvement breeding programs. Therefore, it is essential to have good knowledge of the genome structure and relationships among wild Daucus species. To broaden such knowledge, in this research, the nuclear DNA content for 14 Daucus accessions and four closely related species was estimated by flow cytometry and their pollen morphology was analyzed by light and scanning electron microscopy (SEM). Results The flow cytometric analysis showed a 3.2-fold variation in the mean 2C values among Daucus taxa, ranging from 0.999 (D. carota subsp. sativus) to 3.228 pg (D. littoralis). Among the outgroup species, the mean 2C values were 1.775–2.882 pg. The pollen grains of Daucus were tricolporate, mainly prolate or perprolate (rarely) in shape, and mainly medium or small (rarely) in size (21.19–40.38 µm), whereas the outgroup species had tricolporate, perprolate-shaped, and medium-sized (26.01–49.86 µm) pollen grains. In the studied taxa, SEM analysis revealed that exine ornamentation was striate, rugulate, perforate, or the ornamentation pattern was mixed. At the time of shedding, all pollen grains were three-celled, as evidenced by DAPI staining. We also found high positive correlations between the length of the polar axis (P) and the length of the equatorial diameter (E) of pollen grains, as well as between P and P/E. However, when comparing cytogenetic information with palynological data, no significant correlations were observed. Conclusions This study complements the information on the nuclear DNA content in Daucus and provides comprehensive knowledge of the pollen morphology of its taxa. These findings may be important in elucidating the taxonomic relationships among Daucus species and can help in the correct identification of gene bank accessions. In a broader view, they could also be meaningful for the interpretation of evolutionary trends in the genus.

“…erefore the information on the occurrence of species in areas previously not occupied by them, unnoticed or misidentified with other species, is of great interest to many biologists throughout the world and continues to be published (e.g., Dudáš et al, 2022;Ellis et al, 2022;Nobis et al, 2020;von Raab-Straube & Raus, 2022). In the last issues of ASBP, there also have been published several short notes on new records of the flora of selected countries (Bulakh et al, 2022;Lipińska et al, 2022;Łazarski, 2022;Tlałka et al, 2021;Vončina et al, 2022). us, meeting the expectations of botanical society and Acta Societatis Botanicorum Poloniae / 2023 / Volume 92 / Article 161979 Publisher: Polish Botanical Society at the same time trying to avoid the dispersion of information in many separate short communications, since 2023, we decided to propose a new article type, "New floristic findings" for the permanent collection titled New national and regional plant records: contribution to the flora of an Old World countries.…”

is year marks the 100th anniversary of the Acta Societatis Botanicorum Poloniae (ASBP) establishment, and it is an opportune time to reflect on its contributions to the field of botany. e journal was founded in 1923 by a group of Polish botanists who sought to create a platform for publishing high-quality research in the field. Since then, the journal has published numerous seminal papers that have shaped the course of botany. Currently, the journal covers a wide range of topics, including plant anatomy, ecology, genetics, molecular biology, taxonomy, and systematics. Over the years, the journal has maintained high standards of quality and has been a go-to resource for botanists around the world. e ASBP has published papers by some of the most eminent botanists in the field, including Władysław Szafer, a pioneering Polish botanist and one of the founders of modern plant geography Jan Kornaś, a distinguished phytogeographer and plant ecologist.

This paper presents new data on the occurrence of 16 vascular plant species from five Eurasian countries obtained during field explorations, as well as during taxonomic revisions of herbarium materials. Five taxa (Draba fladnizensis, Gentiana orbicularis, Helianthus giganteus, Symphyotrichum cordifolium, Thalictrum alpinum) are recorded for the first time from Poland, five (Achnatherum jacquemontii, Arrhenatherum elatius, Dittrichia graveolens, Geranium pyrenaicum, Stipa × balkanabatica) from Tajikistan, three (Achnatherum sibiricum, Asyneuma thomsonii, Stipa × balkanabatica) from Kyrgyzstan, one (Orobanche bartlingii) from Turkey, one (Calamagrostis obtusata) from China and one (Calamagrostis emodensis) from the Gansu Province in China. In addition, Hieracium piliferum, considered extinct in Poland, was rediscovered. For each species, synonyms, taxonomy with remarks on recognition and differentiation of the species from the most similar taxa occurring in a given area, general distribution, habitat preferences, as well as a list of recorded localities (often far from the previously known areas) are presented. As a result of the morphological comparison of specimens representing Stipa × balkanabatica collected in Tajikistan and Kyrgyzstan with the type specimen collected from Turkmenistan, we decided to describe a new variety named S. × balkanabatica var. alaiensis M. Nobis & Klichowska, var. nov. Additionally, based on the analysis of phytosociological relevés prepared during field studies in the western Pamir Alai Mts (in Kyrgyzstan and Tajikistan), a new association of chasmophytic plants named Asperulo oppositifoliae–Achnatheretum jacquemontii M. Nobis, Klichowska & A. Nowak, is also described.
