The role of strigolactone and auxin in the regulation of shoot branching
… actors. In this thesis I investigate the role of strigolactone and auxin in controlling bud growth dynamics and their effect on plant branching levels and development more generally. Firstly, I present a novel molecular mechanism for strigolactone perception, developed in collaboration with Prof. …

Understanding the protein complexes involved in the reception of the plant hormone Strigolactone
Strigolactones (SLs) are a class of plant hormone that regulate the development of branching in plants. In petunia, SL is perceived by its receptor, DAD2, an α/β hydrolase fold protein. This receptor also functions as a slow enzyme that hydrolyses SL into two non-active by-products. The hydrolytic …

Use of strigolactone for stress relief and increased productivity in high-yielding environments
… food production to reach its fullest potential. Strigolactones have recently been classified as plant growth regulators, as they have been implicated in the regulation of shoot inhibition and root growth and development. The objective of this study was to determine the ability of a strigolactone …

Regulatory dynamics of axillary bud competition in Arabidopsis
… apparent when studying the effect of strigolactone, a plant hormone which affects both BRC1 expression and the removal of the PIN1 auxin transporter from the plasma membrane. The relative influences of these two arms of strigolactone signaling is poorly understood, because they have …

The hormonal regulation of PIN protein localisation and its relevance to shoot architecture
… by which PINs sense and respond to auxin, strigolactone and cytokinin remain unknown. In this thesis I investigate the regulation of PIN polarity in response to these hormones, presenting evidence of an age-dependent aspect to PIN1 behaviour. I then demonstrate that NPA-sensitive auxin flux …

Computational investigation of molecular recognition in plant hormone signal transduction
… giberellin, jasmonic acid, salicylic acid and strigolactone. Plant hormones are specifically recognized by their receptor proteins, and then initiate downstream protein-protein interactions to trigger a variety of hormone responses. Detailed understanding of the molecular mechanism of specific …

The role of auxin transport in the control of shoot branching
… bud outgrowth, whereas cytokinin promotes it. Strigolactones also inhibit bud outgrowth, by changing properties of the auxin transport network, increasing the competition between buds. This occurs by modulating access to the polar auxin transport stream (PATS) in the main stem. The PATS …

Controlled Hybridization With An Apple Breeding Selection Of Reduced Scion Vigor And The Study Of The Tree Architecture Of Its Offspring
… in the pathway. Exogenous GA3 and GR24 (a strigolactone analog) were applied to plants in progeny 806. Branches treated with GA3 had more new growth due to increased number of nodes as compared to control branches in dwarf plants. Decapitation was conducted before the application of GR24 to …

Exploring the genetic basis of germination specificity in the parasitic plants Orobanche cernua and O. cumana
… class of germination stimulants is the strigolactones (SLs), although some species respond to non-SL compounds, such as dehydrocostus lactone (DCL). Recent work indicates that SLs are perceived by members of the KARRIKIN-INSENSITIVE2 (KAI2) gene family, and suggests that within parasitic …
