Chlamydomonas pitschmannii Ettl, a little known species from thermoacidic environments.
Three Chlamydomonas strains were isolated from the soils of a hot spring located in the Campi Flegrei Caldera (Naples, Italy). Ecophysiological, morpho-cytological and molecular features were used to characterize these isolates and to compare them with chlamydomonax acidophila strains from algal culture collections. The strains were collected from three points of the volcanic site, differing in...
متن کاملA Taxonomic Reassessment of Consolida (Ranunculaceae) Species: Insight from Morphological and Molecular Data
In order to compare the efficiency of morphological traits and molecular markers in distinguishing the Consolida species, molecular analysis using nrDNA ITS and cpDNA trnL-trnF with maximum parsimony and Bayesian methods were done in a total of 34 species and forma representing 28 species of Consolida, 6 species of Aconitella, plus two species of Delphinium and two species of Aconitum as out gr...
متن کاملExtensive chromosomal variation in a recently formed natural allopolyploid species, Tragopogon miscellus (Asteraceae).
Polyploidy, or whole genome duplication, has played a major role in the evolution of many eukaryotic lineages. Although the prevalence of polyploidy in plants is well documented, the molecular and cytological consequences are understood largely from newly formed polyploids (neopolyploids) that have been grown experimentally. Classical cytological and molecular cytogenetic studies both have show...
متن کاملMolecular cytogenetic analysis of recently evolved Tragopogon (Asteraceae) allopolyploids reveal a karyotype that is additive of the diploid progenitors.
Tragopogon mirus and T. miscellus (both 2n = 4x = 24) are recent allotetraploids derived from T. dubius × T. porrifolius and T. dubius × T. pratensis (each 2n = 2x = 12), respectively. The genome sizes of T. mirus are additive of those of its diploid parents, but at least some populations of T. miscellus have undergone genome downsizing. To survey for genomic rearrangements in the allopolyploid...
متن کاملMolecular and morphological taxonomy of Pythium species isolated from soil in West Azarbaijan province (N.W. Iran)
Pythium is a fungus-like genus with worldwide distribution that is found in most terrestrial and aquatic ecosystems. It is a species-rich genus contains important plant pathogenic species. Little is known on the systematics of Pythium in West Azarbaijan province (N.W. Iran). Thus, the aim of this study was to identify 200 isolates collected from different cultivated soils of West Azarbaijan pro...
