Genetic Polymorphism in Wine Yeasts: Mechanisms and Methods for Its Detection
2017
The processes of yeast selection for using as wine fermentation starters have revealed a great phenotypic diversity both at interspecific and intraspecific level, which is explained by a corresponding genetic variation among different yeast isolates. Thus, the mechanisms involved in promoting these genetic changes are the main engine generating yeast biodiversity. Currently, an important task to understand biodiversity, population structure and evolutionary history of wine yeasts is the study of the molecular mechanisms involved in yeast adaptation to wine fermentation, and on remodeling the genomic features of wine yeast, unconsciously selected since the advent of winemaking. Moreover, the…

PERIS, J. B., STUBING, G. & FIGUEROLA, R., 1990. An outline revision of the subsection Gymnocarpae Font Quer of the genus Sideritis L. (Lamiaceae) in the western part of the Mediterranean region. A monographic study of the subsection Gymnocarpae Font Quer has been carried out in which eleven species have been recognized: Sideritis incana L., S. lacaitae Font Quer, S. cuatrecasasii Peris, Stubing & Figuerola, sp. nov., S. sericea Pers., S. oromaroccana Peris, Stubing & Figuerola, nom. nov., S. guyoniana Boiss. & Reuter, S. altiatlantica (Font Quer) Peris, Stubing & Figuerola, comb. & stat. nov., S. glauca Cav., S. atlantica Pomel, S. regimontana (Maire) Peris, Stubing & Figuerola, comb. & st…
Lotus tenuis x L. corniculatus interspecific hybridization as a means to breed bloat-safe pastures and gain insight into the genetic control of proan…
2014
Background: Proanthocyanidins (PAs) are secondary metabolites that strongly affect plant quality traits. The concentration and the structure of these metabolites influence the palatability and nutritional value of forage legumes. Hence, modulating PAs in the leaves of forage legumes is of paramount relevance for forage breeders worldwide. The lack of genetic variation in the leaf PA trait within the most important forage species and the difficulties in engineering this pathway via the ectopic expression of regulatory genes, prompted us to pursue alternative strategies to enhance this trait in forage legumes of agronomic interest. The Lotus genus includes forage species which accumulate PAs …
Gene flow from oilseed rape to weedy species
2003
The assessment of the likelihood of transgene spread from cultivated species to their wild relatives is relevant for oilseed rape (Brassica napus, AACC, 2n=38) as it is partially allogamous and pre...
