ABSTRACT Plants adapt to their local environment through complex interactions between genes, gene networks and hormones. Although the impact of gene expression on trait regulation and evolution has been recognised for many decades, its role in the evolution of adaptation is still a subject of intense exploration.

Differential gene reactions reveal drought response strategies in African acacias
SUMMARY Drought tolerance involves a complex series of genetic reactions that expand over time as water stress intensifies. We investigated gene expression reactions over 43 days of drought stress in two widespread African savanna trees: the umbrella acacia (Vachellia tortilis) and the splendid thorn acacia (Vachellia robusta).

Seed production studies in Ruzi grass (Brachiaria ruziziensis Germain and Everard) : a thesis presented in partial fulfilment of the requirement for the degree of Master of Agricultural Science in Seed Technology, at Massey University, Palmerston North, New Zealand [PDF]
The effect of photoperiod on seed production in Ruzi grass (Brachiaria ruziziensis) was investigated in order to gain a better understanding of reproductive behaviour. The experiment was conducted in a controlled temperature glasshouse which provided day

Epithelial Immunization Induces Polyfunctional CD8+ T Cells and Optimal Mousepox Protection. [PDF]
We assessed several routes of immunization with vaccinia virus (VACV) in protecting mice against ectromelia virus (ECTV). By a wide margin, skin scarification provided the greatest protection. Humoral immunity and resident-memory T cells notwithstanding,
