The detection of plasmid transfer genes in Rhizobium species : a thesis presented in partial fulfilment of the requirement for the degree Master of Science in Microbiology at Massey University, New Zealand
In order that Rhizobium tra genes responsible for Sym plasmid transfer might be found, DNA probes were constructed from Agrobacterium tra genes. Three probes were constructed from DNA containing;- 1) traR, a gene which regulates other tra genes on the Agrobacterium tumefaciens plasmid pTiC58, 2) an …

Design of a microscopy-based screening method for stomatal development genes in <i>arabidopsis thaliana</i>
… are microscopic pores in the epidermis of plants that regulate gas exchange and transpiration. Regulation of stomatal behavior offers opportunity for crop improvement; stomata are also useful for research into cell patterning, differentiation, and development. The purpose of this project …

Genetic analysis of tissue culture responses in barley (Hordeum vulgare L.).
The overall objectives of this thesis were to screen barley genotypes for in vitro culture response; and to use the double haploid (DH) lines derived from the cross between responsive and unresponsive parental lines to confirm the location of previously reported QTL that control barley tissue …

Cloning of novel low and high molecular weight heat shock genes in wheat
… heat shock proteins play a vital role in the plant's ability to survive high temperature stress. Cloning low and high molecular weight HSPs from a thermotolerant variety of wheat will provide a building block for later studies of their function. Moreover, once significance of a HSP gene in …

The effect of pathogens on plant genome stability
… a key factor in determining the resistance of plants, have been shown often to be highly allelic entities existing in duplicated regions of the genome. This characteristic suggests that R-gene acquisition may have arisen through frequent genetic rearrangements as a result of transient, reduced …

Spatio-temporal regulation of pre-symbiotic signalling in arbuscular mycorrhizal symbiosis
… is a ubiquitous and ancient interaction between plant roots and Glomeromycotina fungi, underpinned by a mutualistic nutrient exchange. In this intimate partnership, the fungus dynamically and asynchronously colonises the plant root system and cortex cells. Symbiosis development must therefore …
