| description | Crop yields have increased substantially during the last 50 years, but the traits that drove these remarkable
improvements, such as plant architecture, have a little remaining potential for improvement. New traits such as
photosynthesis, as the ultimate determinant of yield, must be explored to support future demands. However,
improving photosynthetic efficiency has played only a minor role in improving crop yield to date. Chlorophylls
are the pigments allowing light to be transformed into carbohydrates, and therefore help to maintain crop yield
under stress. Chlorophyll content correlates with higher yields in diverse conditions. In this review, we discuss using
chlorophyll content as the basis of screens for drought tolerance. We review chlorophyll-related responses to drought
in different plants and summarize the advantages and disadvantages of current methods to measure chlorophyll
content, with the ultimate goal of improving the efficiency of crop breeding for drought tolerance. |
