In order to anchor Rosa linkage groups to physical chromosomes, a combination of the Tyramide-FISH technology and the modern molecular marker system based on High Resolution Melting (HRM) is an efficient approach. Although, Tyramide-FISH is a very promising technique for the visualization of short DNA probes, it is very challenging for plant species with small chromosomes such as Rosa. In this ...

This study investigates species boundaries in the polyploid complex of Rosa sect. Cinnamomeae east of the Rocky Mountains. This complex is characterized by extensive intra-specific polymorphism that is the consequence, in part, of hybridization and polyploidy. An objective multivariate approach is employed to delimit species in the complex, which involved cluster and ordination analyses of 25 q...

This study investigates the impact of hybridization and polyploidy in the evolution of eastern North American roses. We explore these processes in the Rosa carolina complex (section Cinnamomeae), which consists of five diploid and three tetraploid species. To clarify the status and origins of polyploids, a haplotype network (statistical parsimony) of the glyceraldehyde 3-phosphate dehydrogenase...

To determine the kinetics of tissue macrophage and microglial engraftment after bone marrow (BM) transplantation, we have developed a model using the ROSA 26 mouse. Transplanted ROSA 26 cells can be precisely identified in recipient animals because they constitutively express beta-galactosidase (beta-gal) and neomycin resistance. B6/129 F2 mice were irradiated and transplanted with BM from ROSA...

The concept of γ-semi-regular-open sets and γ-sclosed spaces have been introduced and explored in [6]. In this paper, we continue studying the properties and characterizations of γ-semi-regular open sets and γ-s-closed spaces.

In this paper we have introduced the concept of (γ, γ′)-preopen sets in topological space.

ROSA is a Learning Object (LO) repository system with semantic access, which enables the management of LOs. LO is a collection of reusable material used to support learning, characterized by a set of metadata descriptors. LOs are accessed in a contextualized way, determined by semantic associations between them. This paper presents ROSA+, a system extension that aims at deducing additional sema...

To determine the kinetics of tissue macrophage and microgwere observed. Alveolar macrophage engraftment was evident by 2 months and had increased to 61% of total tissue lial engraftment after bone marrow (BM) transplantation, we have developed a model using the ROSA 26 mouse. macrophages at 1 year posttransplantation. The kinetics of liver Kupffer cell engraftment were similar to those seen in ...
