New chromosome counts, karyotype analyses and asymmetry indices in some taxa of genus Senecio L. and related genera Tephroseris (Rchb.) Rchb. and Turanecio Hamzaoglu belong to tribe Senecioneae (Asteraceae) from Turkey
In this study, the somatic chromosome numbers and karyotype analyses were determined for nine taxa that belong to three different genera of Senecioneae tribe. The studied taxa are; Senecio tauricolus V.A. Matthews, Senecio racemosus (M.Bieb.) DC., Senecio paludosus L., Senecio trapezuntinus Boiss.,...

In this study, the somatic chromosome numbers and karyotype analyses were determined for nine taxa that belong to three different genera of Senecioneae tribe. The studied taxa are; Senecio tauricolus V.A. Matthews, Senecio racemosus (M.Bieb.) DC., Senecio paludosus L., Senecio trapezuntinus Boiss., Senecio inops Boiss. & Balansa subsp. inops, Turanecio pandurifolius (K.Koch) Hamzaoglu, Turanecio hypochionaeus (Boiss.) Hamzaoglu, Turanecio eriospermus (DC.) Hamzaoglu, Tephroseris integrifolia (L.) Holub. subsp. aurantiaca (Hoppe ex Willd.) B.Nord. S. tauricolus, S. trapezuntinus, S. inops subsp. inops and T. hypochionaeus taxa are endemic to Turkey. The chromosomal variability in the tribe Senecioneae has observed the existence of four chromosome numbers: 2n = 38, 2n = 40, 2n = 46 and 2n = 80.
