Candida albicans: genotyping methods and clade related phenotypic characteristics BJM
Lyon,Juliana P.; Moraes,Karen C.M.; Moreira,Leonardo M.; Aimbire,Flávio; Resende,Maria Aparecida de.
Several molecular methods, such as Southern blotting hybridization, Multilocus Sequence Typing, and DNA microsatellite analysis, have been employed to genotype Candida albicans. The genotype analysis allows to group strains in clades, that is, a group composed of one ancestor and its descendants. These genotype studies demonstrate that clades distribution is influenced by geographic area as well as that antifungal resistance is associated with particular clades. These findings suggested that C. albicans reproduces mainly in a clonal manner, with certain degree of DNA microevolution. Additionally, virulence factors and site of isolation have also been associated with clade specificity. The present article is a brief review about the methods used for Candida...

Is the evolutionary theory still useful?: A review with examples RChHN
NESPOLO,ROBERTO F.
Evolutionary biology is experiencing an exceptional process of revisión and outreach because of the 200-anniversary if the birth of Charles Darwin. As a consequence, the study of organic evolution and also its teaching are being discussed at several levels, by evolutionary biologists, biologists and scholars outside evolutionary biology and by the general public. In this scenario, a didactic explanation of how biologists address evolutionary research in real populations seems to be useful. Using actual research examples, here I tried to outline how the classic theory (termed here as the "basic scheme") is useful to answer relevant questions in biology and how a less dogmatic paradigm (or a more versatile one) would be needed when dealing with the most...

Morphological and molecular diversity of 47 melon (Cucumis melo) cultivars compared to an extinct landrace excavated from the 15th century National Institute of Agronomic Research
Szabó, Z.; Gyulai, G.; Tóth, Z.; Heszky, L..
Morphological diversity of 47 melon (Cucumis melo L.) cultivars and landraces from Hungarian germplasm collection were analyzed. Cluster analysis based on 26 morphological (quantitative and qualitative) traits revealed an extreme diversity among accessions, however cultivars were clustered into three types of cantalupensis, reticulatus and inodorus. Molecular (SSR, ITS) and morphological dendrograms were compared and the genotype of medieval sample was reconstructed

Soft inheritance: challenging the modern synthesis Genet. Mol. Biol.
Jablonka,Eva; Lamb,Marion J..
This paper presents some of the recent challenges to the Modern Synthesis of evolutionary theory, which has dominated evolutionary thinking for the last sixty years. The focus of the paper is the challenge of soft inheritance - the idea that variations that arise during development can be inherited. There is ample evidence showing that phenotypic variations that are independent of variations in DNA sequence, and targeted DNA changes that are guided by epigenetic control systems, are important sources of hereditary variation, and hence can contribute to evolutionary changes. Furthermore, under certain conditions, the mechanisms underlying epigenetic inheritance can also lead to saltational changes that reorganize the epigenome. These discoveries are clearly...
