ABSTRACT
In this research the chromosomes of Turbinicarpus valdezianus were studied in diakinesis and metaphase I, from native plants located near Saltillo, Coahuila (Mexico). A chromosome number 2n = 2 x = 22 was found, which is consistent with the basic number x = 11, previously reported for other members of the cactus family. The normal bivalent pairing observed in all the analyzed cells indicates that this is a diploid species with regular chromosome segregation. The analysis of meiotic configuration frequencies supports the hypothesis of one or more chromosome pairs being non-metacentric.

    Members of the ALMT gene family contribute to the Al3+ resistance of several plant species by facilitating malate efflux from root cells. The first member of this family to be cloned and characterized, TaALMT1, is responsible for most of the natural variation of Al3+ resistance in wheat. The...
