Micropropagation of Glandularia perakii Cov. et Schn. (Verbenaceae), a native species with ornamental potential.
Glandularia perakii is a perennial species with beautiful violet flowers that grows in the stony soil of Mendocine pedemont. A plentiful and prolonged flowering confers it an important ornamental potential. In this paper, a method of propagation of G. perakii from nodal segments is reported. Proliferating microshoot cultures were obtained by placing nodal segment on Murashige and Skoog medium (...

Automatically Moving between Levels in Artificial Chemistries
We introduce multi-level Artificial Chemistries as a way of tackling difficult problems in the evolution of complexity. We present two algorithms for moving between levels of abstraction in a multi-level Artificial Chemistry. (1) Moving upwards from a low-level description to a high-level description involves making approximations. We discuss these, and provide an algorithm to perform the appro...
متن کاملHybridization between two polyploid Cardamine (Brassicaceae) species in North-western Spain: discordance between morphological and genetic variation patterns.
BACKGROUND AND AIMS Hybridization is an important evolutionary phenomenon, and therefore a detailed understanding of the dynamics of interspecific gene flow and resulting morphological and genetic patterns is of widespread interest. Here hybridization between the polyploids Cardamine pratensis and C. raphanifolia at four localities is explored. Using different types of data, the aim is to provi...
متن کاملVariability in the amount of homoeologous pairing among F1 hybrids
Genes involved in the exclusive pairing of homologous chromosomes have been described in several polyploid species but little is known about the activity of these genes in diploids (which have only one dose of each homoeologous genome). Analysis of the meiotic behaviour of species, natural and artificial hybrids and polyploids of Glandularia suggests that, in allopolyploids where homoeologous g...
