Biography

Dr. Mariela Inés Monteoliva is interested in physiological responses to drought stress, and those responses mediated by mycorrhizal interactions in legumes and grasses. Her main goal is to learn about drought responses mediated or not by mycorrhizal and to contribute to breeding programs for drought tolerance keeping the ability to get benefits from the native mycorrhiza from agricultural fields.

  Breeding for Drought Tolerance by Monitoring Chlorophyll Content
  Author(s): Mariela Inés Monteoliva*, María Carla Guzzo and Gisella Anabel Posada
  
  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 chlorophyl.. View more»
