Fruit development and diversification

Fruit evolution and diversification in campanulid angiosperms.

With increases in both the size and scope of phylogenetic trees, we are afforded a renewed opportunity to address long-standing comparative questions, such as whether particular fruit characters account for much of the variation in diversity among flowering plant clades. Studies to date have reported conflicting results, largely as a consequence of taxonomic scale and a reliance on potentially ...

Diversification and Development

This paper explores the relationship between output volatility and economic development. We develop a methodology to assess countries’ extent of sectoral diversification. The productive structure of a country tends to be risky when the country (i) specializes in highly volatile sectors, (ii) has high sectoral concentration, and/or (iii) specializes in sectors highly affected by country-specific...

Functional diversification of AGAMOUS lineage genes in regulating tomato flower and fruit development

AGAMOUS clade genes encode MADS box transcription factors that have been shown to play critical roles in many aspects of flower and fruit development in angiosperms. Tomato possesses two representatives of this lineage, TOMATO AGAMOUS (TAG1) and TOMATO AGAMOUS-LIKE1 (TAGL1), allowing for an analysis of diversification of function after gene duplication. Using RNAi (RNA interference) silencing, ...

Fruit development and ripening

Fruiting structures in the angiosperms range from completely dry to highly fleshy organs and provide many of our major crop products, including grains. In the model plant Arabidopsis, which has dry fruits, a high-level regulatory network of transcription factors controlling fruit development has been revealed. Studies on rare nonripening mutations in tomato, a model for fleshy fruits, have prov...
