| Multilocus phylogenetic analysis of true morels (Morchella) reveals high levels of endemics in Turkey relative to other regions of Europe. | The present study was conducted to better understand how the phylogenetic diversity of true morels (Morchella) in Turkey compares with species found in other regions of the world. The current research builds on our recently published survey of 10 Turkish provinces and another of the world in which DNA sequence data from 247 and 562 collections, respectively, were analyzed phylogenetically. Herein we report on phylogenetic analyses of 243 additional collections made during the spring of 2009 and ... | 2011 | 22123659 |
| dna polymorphism in morels: complete sequences of the internal transcribed spacer of genes coding for rrna in morchella esculenta (yellow morel) and morchella conica (black morel). | the internal transcribed spacer (its) of the gene coding for rrna was sequenced in both directions with the gene walking technique in a black morel (morchella conica) and a yellow morel (m. esculenta) to elucidate the its length discrepancy between the two species groups (750-bp its in black morels and 1,150-bp its in yellow morels. | 1996 | 8795250 |
| phylogeny and historical biogeography of true morels (morchella) reveals an early cretaceous origin and high continental endemism and provincialism in the holarctic. | true morels (morchella, ascomycota) are arguably the most highly-prized of the estimated 1.5 million fungi that inhabit our planet. field guides treat these epicurean macrofungi as belonging to a few species with cosmopolitan distributions, but this hypothesis has not been tested. prompted by the results of a growing number of molecular studies, which have shown many microbes exhibit strong biogeographic structure and cryptic speciation, we constructed a 4-gene dataset for 177 members of the mor ... | 2011 | 20888422 |
| molecular characterization of morchella species from the western himalayan region of india. | the molecular diversity of thirty-two different morchella cultures/fruiting bodies, collected from the western himalayan region was studied in this investigation. considerable taxonomic confusion exists regarding many species of morchella. although classical taxonomy is helpful in identification for many ascomycetes, morels exhibit considerable morphological diversity and there is disagreement in the identification of morel species. phylogenetic analyses based on dna sequences could help in sort ... | 2011 | 21188589 |
| molecular identification and characterization of the edible and medicinal morchellaceae germplasm collection of "mulch morels". | the accessions of the morel (morchellaceae, ascomycota) germplasm collection were genetically analyzed, in order to determine both their inter- and intraspecific relationships. this was done as a starting point for cultivation experiments, as well as to provide a genetic description of invasive morel populations linked to mulched garden patches, as compared with outdoor morels. the phylogenetic data, which was based on the internal transcribed spacer (its) sequences and supported by amplified fr ... | 2011 | 22164767 |
