Organisms in nature adapt and evolve in complex environments. For example, when subjected to changes in nutrients, antibiotics, and predation, microbes in the wild face the challenge of adapting multi...
Normal chloroplast development in rice is essential for photosynthesis and yield potential. To explore the physiological and molecular mechanism of chloroplast development, we isolated the rice mutant...
Canine parvovirus, or CPV, emerged as a deadly threat to dogs in the late 1970s, most likely the result of the direct transfer of feline panleukopenia or a similar virus from domesticated cats.CPV has...
Crocodilians, including the Australian saltwater crocodile, mutate at about a quarter of the rate of birds, new research has revealed.The discovery is the result of genome sequencing three crocodilian...
Genetic screens which assay behavior have been successfully used to identify genes required for neural function. This thesis is the analysis of midline uncoordinated (muc), a mutation identified for i...
The zebrafish belladonna (bel) mutation was identified in a large-scale mutagenesis screen to identify genes involved in retino-tectal pathfinding in Tubingen, Germany. In bel mutants, after exiting t...
A University of Texas at Arlington team exploring pigeons as a model for vertebrate evolution has uncovered that mutations and interactions among just three genes create a wide range of color variatio...
University of Texas (UT) at Arlington researchers, working in parallel with researchers at the University of Utah, examined three genes that control multiple color phenotypes, or appearances, in pige...
A total of 423 blood samples were collected (during 2009 and 2010) from all the ram holdings at three major Jordanian governmental Awassi breeding stations (Al-Khanasry, Al-Mushairfa and Al-Fjaje) and...
Let Q be an acyclic quiver and s be a sequence s with elements in the vertex set Q_0. We describe a sequence of simple (backward) tilting in the bounded derived category D(Q), starting from the standa...
If K is a knot or link in R3 and S  R3 is a smoothly embedded 2-sphere meeting K transversely in 4-points, then one can form a new knot or link K′ as follows. One cuts R3 along S and then glues the t...
We study ‘silting mutaion’ for self-injective algebras. In particular we focus ontilting mutationand show that iterated irreducible ‘silting mutation’ transitively act on the set of silting objec...
The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this interplay is still not completely understood. This paper presents...
The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this inter-play is still not completely understood.
Mutation of skew-symmetrizable matrices is a fundamental oper-ation that first arised in Fomin-Zelevinsky’s theory of cluster algebras; it also appears naturally in many different areas of mathematics...
