ASHS 2015 Annual Conference

Objective(s):
1. Provide an overview of advances in the understanding of the intrinsic and environmental cues of root architecture development 2. Highlight advances in the study of root architecture & physiology in some horticultural species 3. Examine current challenges in the study of root development & physiology in horticultural species 4. Stimulate research collaborations through interactions and networking among the participants

It is becoming increasingly evident that optimization of root architecture for resource capture is vital for enabling the next green revolution. In globally important cereals such as maize and rice, the enhanced knowledge of root architecture has already led to measurable gains in the ability to exploit soil resources with corresponding enhancements in yield attributes. Although cereals provide much needed calories, horticultural crops are essential to human health and food security on a global scale. Yet, knowledge about root architecture in horticultural species is limited and measurement of root growth and root system architecture are often overlooked in horticultural research. The overarching goal of this workshop is to highlight the hidden half of horticultural crops, the root system. One of the goals of this workshop is to provide an overview of advances in model systems, focusing on the adaptive strategies that plant root systems have developed to cope with a variety of environmental stresses. In addition, the workshop will highlight advances in the study of root architecture and physiology in some horticultural species. Understanding how plant roots respond to environmental challenges is critical in the development and testing of tools and practices for modifying plant growth, especially in regions characterized by low input agriculture. Knowledge of the intrinsic signals that mediate root development and affect resource capture will facilitate the development of crop varieties that are tolerant to a range of growing environments.
