Name(s): Creator (cre): Nguyen, Hai, Thesis advisor (ths): Emery, R.J. Neil, Degree committee member (dgc): Saville, Barry, Degree committee member (dgc): Kisiala, Anna, Degree granting institution (dgg): Trent University
Abstract: <p>Phytohormones, Cytokinin (CK) and Abscisic acid (ABA), are best known for controlling plant growth and stress responses; but they also mediate various developmental perspectives in alga. Yet, their mode of action in algal adaptive strategies to heavy metal responses, their involvement in orchestration of phytohormone crosstalk remain largely unknown and a molecular framework of… more

Name(s): Creator (cre): Cheung, H.Y. Kitty, Thesis advisor (ths): Saville, Barry J, Degree committee member (dgc): Brunetti, Craig R, Degree committee member (dgc): Emery, R.J. Neil, Degree granting institution (dgg): Trent University
Abstract: <p>Ustilago maydis (D.C.) Corda is a biotrophic pathogen that secretes effectors to establish and maintain a relationship with its host, Zea mays. In this pathosystem, the molecular function of effectors is well-studied, but the regulation of effector gene expression remains largely unknown. This study characterized Zfp1, a putative U. maydis Zn(II)2Cys6 transcription factor, as a modulator… more

Time-dependent effects of predation risk on stressor reactivity and growth in developing larval anurans (Lithobates pipiens)

Name(s): Creator (cre): Longhi, Jessica N., Thesis advisor (ths): Murray, Dennis L, Thesis advisor (ths): Kerr, Leslie R, Degree committee member (dgc): Emery, R.J. Neil, Degree granting institution (dgg): Trent University
Abstract: <p>The predator vs. prey dynamic is an omnipresent factor in ecological systems that may drive changes in life history patterns in prey animals through behavioural, morphological, and physiological changes. Predation risk can have profound effects on the life history events of an animal, and is influenced by the neuroendocrine stress response. Activation of the hypothalamic-pituitary-… more
