Extremes of Moisture: Enhancing excess moisture tolerance in barley through manipulation of phytoglobins

Crop Types

Collaborating Locations


Phytoglobins (PGBs) are animal-Like hemoglobins found in plants, and participate in plant response to biotic and abiotic stress. Increase Pgb levels in corn and soybeans exhibit tolerance o excess moisture and other stressors, while reduced Pgb levels showed that plants were more susceptible to the same stress. The goal of this study was to measure Pgb in a number of barley genotypes and correlate this to the performance to excess moisture, as well as investigate metabolic responses and key enzymes known to be involved in excessive moisture tolerance.

This project is a sub-project of a multi-collaborator project on the Extremes of Moisture.

Key Takeaways

There was issues with the unpredictability of field work (Fall 2019 = wet, 2020=COVID, 2021= Dry) therefor there was an issue with gaining positive results. However, under these conditions, they did find that moving topsoil upslope did not create areas of water ponding in depressions and did not transfer weed seeds upslope to germinate.
