Sorbus domestica L. (Rosaceae) en Extremadura (España)

Inheritance of the chloroplast genome in Sorbus aucuparia L. (Rosaceae).

Chloroplast DNA (cpDNA) inheritance was investigated in Sorbus aucuparia using progenies obtained from six controlled crosses between individuals of known haplotype. Polymerase chain reaction (PCR) amplification, followed by restriction analysis, was used to characterize 248 offspring for either of two polymorphic cpDNA fragments. All offspring exhibited the maternal haplotype, which indicates ...

[Borreliosis de Lyme en España].

La temperatura es el estímulo para el comienzo de la actividad, mientras que la supervivencia depende de la humedad. Las condiciones climáticas modifican la actividad estacional de las garrapatas. Las ninfas son el principal vector de la enfermedad para el hombre. Por ello, el mayor riesgo de adquirir la enfermedad es durante el período de actividad de las ninfas: la primavera en zonas no húmed...

Population structure at the S-locus of Sorbus aucuparia L. (Rosaceae: Maloideae).

Low sequence divergence within functional alleles is predicted for the self-incompatibility locus because of strong negative frequency-dependent selection. Nevertheless, sequence variation within functional alleles is essential for current models of the evolution of new mating types. We genotyped the stylar self-incompatibility RNase of 20 Sorbus aucuparia from a population in the Pyrenees moun...

Mycological flora on tree fruits, crust, leaves and pollen Sorbus domestica L.

Plant-microbial interactive relations with respect to determine mycoflora of the Sorbus domestica L.--fruits, crust, leaves and pollen were studied in 2 Slovak regions. On the fruit samples the genera Alternaria, Botrytis, Cladosporium, Mucor and Penicillium occurred, on the leaves the genera Alternaria, Cladosporium and Penicillium prevailed and on crust the genera Alternaria, Cladosporium, Pe...
