The evolutionary adaptation of plant genes is a multifaceted process that enables plants to endure and flourish in a variety of changing environments. This adaptation takes place through mutations, alterations in gene expression, and the mechanisms of natural selection, allowing plants to acquire traits such as drought resistance, pest resilience, and effective nutrient absorption. Over time, these genetic modifications accumulate, equipping plants to better handle their surroundings. Key Adaptations in Plant Genes: 1. Drought and Water Stress Resistance Plants in dry regions have developed genes that help them survive with minimal water. Genes that regulate traits like stomatal closure and root depth assist plants in minimizing water loss while maximizing water uptake. These genes have emerged through selective pressure, favoring those plants that can endure arid conditions. For example, succulents possess genes that facilitate water storage in their tissues, enabling them to survive ...
