Investigation into the use of molecular methods to distinguish between species of Caladenia subgenus Calonema
The phylogeny of typical spider orchid (Caladenia subgenus Calonema) is investigated for the first time. The analyses were performed using 17 RAPD and 10 ISSR primers on 30 taxa representing the three spider orchid groups (the dilatata, patersonii and reticulata groups) yielding 135 RAPD and 63 …

Identifying genes that confer ethanol tolerance in Saccharomyces cerevisiae
S. cerevisiae has evolved the ability to tolerate high concentrations of ethanol, a trait that has contributed to this yeast being a cornerstone of beverage and biofuel industries. The key genes involved in conferring ethanol tolerance in S. cerevisiae are unknown. One strategy used to identify …

Investigation of the oxytocin receptor gene in sheep
The increase in uterine oxytocin receptor (OTR)concentrations over the late luteal phase of the estrous cycle in sheep is thought to play an important role in the regulation of the cycle length by facilitating the effect of oxytocin on uterine prostaglandin release. At the end of pregnancy, a …

Identification and characterisation of bacterial genes associated with resistance to and/or degradation of environmental pollutants
Bacteria were previously isolated from two separate sites, one contaminated with lead and the other with Polycyclic Aromatic Hydrocarbons (PAHs). Alcaligenes sp. AO22 and Arthrobacter sp. E9 were identified from the lead contaminated site, while Stenotrophomonas maltophilia was identified from the …

Blonde hair colour: classification, characterisation and genetic associations for use in forensic science
The vast variety of normal pigmentation variation is a huge genetic puzzle and hair colour is one part of this puzzle. It is hypothesised that there are genetic variants specifically associated with an objectively defined Blonde phenotype. The first objective of this study was to examine the …

Prediction of age from DNA
Currently DNA profiling methods only compare a suspect’s DNA with DNA left at the crime scene. When there is no suspect, it would be useful for the police to be able to predict what the person of interest looks like by analysing the DNA left behind in a crime scene. Determination of the age of the …

Molecular divergence within the blue penguin (Eudyptula minor (Forster)) complex : A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Science with Honours
There have been numerous taxonomic revisions to the genus Eudyptula (blue penguins). Originally, all blue penguin populations were described as a single species, E. minor, but there has been taxonomic instability since (Turbott, 1990). Kinsky and Falla (1976) proposed that E. minor comprised six …

Associations between gene variations and milk composition in New Zealand dairy cattle: A thesis submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… are useful tools for improving animal genetics and breeding. They have become an increasingly useful method for selecting superior dairy cattle, as the valued milk traits are dependent on multiple factors including genetics, breed, diet, and feeding system. In this context, this …

Genetics of disease resistance: Molecular characterisation of the major histocompatibility Complex Class II genes in Bos species of different origin : A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science at Lincoln University
Breeding for genetic resilience in farm animals is becoming more important as a consequence of the increasing awareness of pathogen resistance to antibiotics and the need to build more resilient and sustainable agricultural production systems. In this context, the important role the Major …
