- Soil persistence and biodiversity of ericoid mycorrhizal fungi in the absence of the host plant in a Mediterranean ecosystemRoberta Bergero
Dipartimento di Biologia Vegetale, Università di Torino and IPP sez Torino, Viale Mattioli 25, 10125 Turin, Italy
Mycorrhiza 13:69-75. 2003..Their persistence could favour the establishment of E. arborea seedlings in pure Q. ilex forests after disturbance phenomena...
- Preservation of the Y transcriptome in a 10-million-year-old plant sex chromosome systemRoberta Bergero
Institute of Evolutionary Biology, University of Edinburgh, Kings Buildings, Ashworth Laboratories, Edinburgh EH9 3JT, UK
Curr Biol 21:1470-4. 2011....
- AT-rich sequences from the arbuscular mycorrhizal fungus Gigaspora rosea exhibit ARS function in the yeast Saccharomyces cerevisiaeRoberta Bergero
Crop and Soil Research Group, Scottish Agricultural College, King s Buildings, West Mains Road, Edinburgh EH9 3JG, UK
Fungal Genet Biol 43:337-42. 2006..Disruption of this element and removal of one TIR increased plasmid stability several fold. The potential for palindromes to affect DNA replication is discussed...
- Evolutionary strata on the X chromosomes of the dioecious plant Silene latifolia: evidence from new sex-linked genesRoberta Bergero
Institute of Evolutionary Biology, School of Biological Sciences, University of Edinburgh, Edinburgh EH9 3JT, United Kingdom
Genetics 175:1945-54. 2007..We can now conclude that the divergence value is saturated, confirming the cessation of X-Y recombination in the evolution of the sex chromosomes at approximately 10-20 MYA...
- Enhanced activity of the GmarMT1 promoter from the mycorrhizal fungus Gigaspora margarita at limited carbon supplyRoberta Bergero
Crop and Soil Research Group, Scottish Agricultural College, King s Buildings, West Mains Road, Edinburgh, EH9 3JG, UK
Fungal Genet Biol 44:877-85. 2007..We speculate that GmarMT1-encoded protein, with its proved metal binding ability, could regulate the homeostasis of zinc, a fundamental cofactor involved in C metabolism regulation and glucose repression...
- Active miniature transposons from a plant genome and its nonrecombining Y chromosomeR Bergero
Institute of Evolutionary Biology, Ashworth Laboratories, University of Edinburgh, Edinburgh, EH9 3JT, United Kingdom
Genetics 178:1085-92. 2008..In contrast, insertions on the Y chromosomes were present at high frequencies. Their potential contribution to Y degeneration is discussed...
- Defining regions and rearrangements of the Silene latifolia Y chromosomeR Bergero
Institute of Evolutionary Biology, University of Edinburgh, Ashworth Laboratories, Edinburgh EH9 3JT, United Kingdom
Genetics 178:2045-53. 2008..Future deletion mapping work should ensure that markers are studied in the parents of deletion mutants and should probably include additional deletions that were not ascertained by causing mutant sex phenotypes...
- A new plant sex-linked gene with high sequence diversity and possible introgression of the X copyV B Kaiser
Institute of Evolutionary Biology, School of Biological Sciences, The University of Edinburgh, Edinburgh, UK
Heredity (Edinb) 106:339-47. 2011..However, SlX9 has higher diversity than other genes on the S. latifolia X chromosome. We evaluate the hypothesis of introgression from the closely related species S. dioica as an explanation for the high sequence diversity observed...
- Slcyt, a newly identified sex-linked gene, has recently moved onto the X chromosome in Silene latifolia (Caryophyllaceae)Vera B Kaiser
Institute of Evolutionary Biology, School of Biological Sciences, The University of Edinburgh, Edinburgh, United Kingdom
Mol Biol Evol 26:2343-51. 2009..diclinis and S. latifolia/S. dioica. Diversity at Slcyt is extremely low (pi(syn) = 0.16%), and we find an excess of high frequency-derived variants and a negative Tajima's D, suggesting that the translocation was driven by selection...

Curr Biol 18:545-9. 2008..We detect signs of degeneration in most of the Y-linked gene sequences analyzed, similar to those of animal Y-linked and neo-Y chromosome genes...
