The article discusses the impact of root metaxylem area on drought tolerance and transpiration in pearl millet, a crucial cereal for food security in drylands. The study found that larger metaxylem area in roots positively correlated with grain weight and its maintenance under drought conditions. Additionally, genotypes with larger metaxylem area exhibited different water use strategies depending on soil texture, with water savings mediated by transpiration restriction under high evaporative demand. The research emphasizes the role of soil hydraulic properties in shaping plant hydraulics and drought tolerance. [Extracted from the article] |
