Neocentrics and holokinetics (holocentrics): chromosomes out of the centromeric rules.
The centromere appears as a single constriction at mitotic metaphase in most eukaryotic chromosomes. Holokinetic chromosomes are the exception to this rule because they do not show any centromeric constrictions. Holokinetic chromosomes are usually forgotten in most reviews about centromeres, despite their presence in a number of animal and plant species. They are generally linked to very intrig...
متن کاملA new nomenclature for fungi
Important changes brought about by the Melbourne International Code of Nomenclature for Algae,FungiandPlantsare briefly reviewed concerning a clarification of the spelling and typification of sanctioned fungal names, the recognition of electronic publication for the validity of nomenclatural novelties, permission to use English diagnoses or descriptions for their valid publication, and the requ...
متن کاملA revised nomenclature for allergy. An EAACI position statement from the EAACI nomenclature task force.
This report has been prepared by an EAACI task force representing the five EAACI Sections and the EAACI Executive Committee composed of specialists that reflect the broad opinion on allergy expressed by various clinical and basic specialties dealing with allergy. The aim of this report is to propose a revised nomenclature for allergic and related reactions that can be used independently of targ...
متن کاملThe centromeric protein Sgo1 is required to sense lack of tension on mitotic chromosomes.
Chromosome alignment on the mitotic spindle is monitored by the spindle checkpoint. We identify Sgo1, a protein involved in meiotic chromosome cohesion, as a spindle checkpoint component. Budding yeast cells with mutations in SGO1 respond normally to microtubule depolymerization but not to lack of tension at the kinetochore, and they have difficulty attaching sister chromatids to opposite poles...
متن کاملCentromeric and noncentromeric ADE2-selectable fragmentation vectors for yeast artificial chromosomes in AB1380.
We have constructed a set of fragmentation vectors for the truncation of either the centromeric or the noncentromeric end of YACs containing a human DNA insert. These vectors carry ADE2 or HIS5 as the selectable marker, enabling direct use in AB1380, the host strain of most publicly available YAC libraries. Centromeric fragmentation vectors for AB1380 have not been reported previously; the nonc...
