Key Questions

Grapevine trunk diseases (GTD) are a major threat to the wine industry, causing yield loss and dieback of grapevines. While the increasing damage caused by GTDs in recent decades have spurred several studies on grapevine-associated pathogenic fungi, key questions about the emergence and severity of GTDs remain unanswered, including possible differences in plant pathogenic fungal communities in asymptomatic and symptomatic grapevines. We generated fungal DNA metabarcoding data from soil, bark, and perennial wood samples from asymptomatic and symptomatic grapevines sampled in three terroirs. We observed larger compositional differences in plant pathogenic fungi among different plants parts within grapevine plants than among individual grapevines. This is driven by the dominance of GTD-associated fungi in perennial wood and non-GTD pathogens in soil, as well as by the lack of significant differences among asymptomatic and Esca symptomatic grapevines. These results suggest that fungi generally associated with Esca disease belong to the core grapevine microbiome and likely are commensal endophytes and/or latent saprotrophs, some of which can act as opportunistic pathogens on stressed plants. In addition, we found significant compositional differences among sampling sites, particularly in soil, which suggest a certain influence of local edaphic and mesclimatic factors on plant pathogenic fungal communities. Furthermore, the observed differences among terroirs in plant pathogenic fungal communities in grapevine woody parts indicate that environmental factors likely are important for the development of Esca disease and further studies are needed to investigate the abiotic conditions on fungal compositional dynamics in Esca-affected plants.

Key Questions

The Penfolds case is designed to help students think through brand positioning and brand portfolio questions. Penfolds, one of the world's best known brands of wine, is performing poorly and a new management team needs to quickly reverse the business trends. To do so, the new management team needs to answer key questions, such as: What is Penfolds' positioning? Has the brand extended too far? Can Penfolds successfully play in all price segments of the wine industry? What is the best way to grow the brand going forward?Students will learn about brand portfolio issues and brand positioning. The case is designed to prompt a discussion about how far a brand can extend without losing meaning, and the use of different branding elements such as sub-brands and endorsers.

Key Questions

In this paper, I present accent-related variations unique to Asian-Indian speakers of English in the United States and identify specific speech and language features that contribute to an “Indian accent.” I present a model to answer some key questions related to assessment of Indian accents and help set a strong foundation for accent modification services.
