TR4: will history repeat itself? : ProMusa blog | Promusa - Mobilizing banana science for sustainable livelihoods

TR4: will history repeat itself? : ProMusa blog | Promusa - Mobilizing banana science for sustainable livelihoods | Plant science | Scoop.it

TR4: will history repeat itself? - ProMusa blog" Looming large on the horizon is a new threat to African banana farmers: the tropical race 4 variant of Fusarium wilt (better known as TR4). TR4 was thrust into the limelight when it destroyed commercial Cavendish plantations in Malaysia and Indonesia in 1988. The killer fungus went viral (sorry) and spread to banana production areas in four more countries, including China. Once introduced, TR4 spreads rapidly with infected planting material, on contaminated tools, and in contaminated water and soil.

Trends Plant Science: Unifying concepts and mechanisms in the specificity of plant–enemy interactions (2012)

Trends Plant Science: Unifying concepts and mechanisms in the specificity of plant–enemy interactions (2012) | Plant science | Scoop.it

Host ranges are commonly quantified to classify herbivores and plant pathogens as either generalists or specialists. Here, we summarize patterns and mechanisms in the interactions of plants with these enemies along different axes of specificity. We highlight the many dimensions within which plant enemies can specify and consider the underlying ecological, evolutionary and molecular mechanisms. Host resistance traits and enemy effectors emerge as central players determining host utilization and thus host range. Finally, we review approaches to studying the causes and consequences of variation in the specificity of plant–enemy interactions. Knowledge of the molecular mechanisms that determine host range is required to understand host shifts, and evolutionary transitions among specialist and generalist strategies, and to predict potential host ranges of pathogens and herbivores.

Probably too advanced for an introductory class like Botany 130, but might be able to use in some form in teaching another class.
