Short CV

Lintle Mohase grew up in Lesotho, and obtained her Cambridge overseas school leaving certificate (COSC) in 1989. She then joined the National University of Lesotho where she obtained her B Sc degree (Biology and Chemistry) in 1994. She worked as a Biology teacher until she enrolled for a B Sc (Hons) at the University of the Free State in 1996. In 1998 she obtained her M Sc degree (with Distinction) on a project entitled "Eliciting and signal transduction events of the Russian wheat aphid resistance response in wheat", which also let to her being awarded Prof van Zinderern Bakker price for an oustanding M Sc study. In 2004 she obtained her Ph D at the same university. She has presented several conference papers and is a memeber of the South African Association of Botanists (SAAB).

Publications (Short List)



To combat reliance on pesticides in agricultural systems, particularly wheat production, we investigates the mechanisms of plant defence responses against the Russian wheat aphid (RWA, Diuraphis noxia). We investigate the involvement of various phytohormones in the expression of the resistance response of wheat. We study the biosynthetic pathways, quantify the various hormones, and investigate the cross-talk therein. We also study the mechanisms of priming using certain commercially available plant activators. Furthermore, we investigate the potential of aphid saliva as a source of elicitors/effectors during aphid infestation. The active compounds are isolated, characterised, and identified, and their eliciting potential in various genetic backgrounds evaluated. We conduct treatments under greenhouse and field conditions, in collaboration with entomologists, the Agricultural Research Council, and industry (manufacturers of plant activators).  Results of this study will eventually feed into integrated pest management strategies, where inherent plant resistance mechanisms are activated to protect plants without compromising plant yield and quality, thus ensuring food availability.

Courses Presented

BTNY2626: Introductory plant development and biotechnology

The module describes plant functions and responses of plants associated with nutrion, growth and development, and interaction with the environment. The practical component of the module deals with biotechnological applications of plant physiology which benefit man and the environment.

BTNY3744: Plant defence and biotechnology (practical). The practical investigates the expression of inducible defence responses during pest infestation in resistant and susceptible plants. The activities of key enzymes in the generation of defence related signalling molecules and the downstream defences such as induction of pathogenesis related proteins are measured. Concepts in plant defence mechanisms are used to develop tools to protect plants against stress (pests)

BTNY6844: Plant defence and applications. Plant growth and development is constantly influenced by biotic and abiotic stress. The plant defends itself against such adversities through various defence systems. The module deals with induced plant defence mechanisms against pests and pathogens. Interactions between plants and pests/pathogens are described in terms of compatibility or incompatibility and various factors contributing to the defence phenomena are discussed. The module is discussed with reference to published research articles and key concepts such as specific/general resistance, acquired resistance, susceptibility, signals and signal transduction, plant activators, and effectors of induced defence responses, are described.
