TLDR
Levels of amino acids, most notably proline, tryptophan, and the branched chain amino acids leucine, isoleucines, and valine were increased under drought stress in all cultivars and Excalibur, a cultivar genotypically related to Kukri, showed a pattern of response that was more similar to KUKri under well-watered conditions.About:

Environmental metabolomics: an emerging approach to study organism responses to environmental stressors
TL;DR: Using a wide variety of model organisms, metabolomic studies have detected stress from abiotic factors such as xenobiotic exposure and temperature shifts as well as biotic stressors such as herbivory and competition.

TL;DR: The results indicate the importance of photorespiration and raffinose family oligosaccharide metabolism in grain yield under drought and suggest single or multiple metabolites as potential metabolic markers for the breeding of abiotic stress-tolerant maize.

Plant Productivity and Environment
TL;DR: An analysis of major U.S. crops shows that there is a large genetic potential for yield that is unrealized because of the need for better adaptation of the plants to the environments in which they are grown.

Controlling the false discovery rate in behavior genetics research
TL;DR: The False Discovery Rate (FDR) is the expected proportion of false discoveries among the discoveries, and controlling the FDR goes a long way towards controlling the increased error from multiplicity while losing less in the ability to discover real differences.

Plant responses to drought, salinity and extreme temperatures: towards genetic engineering for stress tolerance
TL;DR: The present review summarizes the recent advances in elucidating stress-response mechanisms and their biotechnological applications and examines the following aspects: regulatory controls, metabolite engineering, ion transport, antioxidants and detoxification, late embryogenesis abundant (LEA) and heat-shock proteins.
