This Episode examine the anatomical, physiological, and molecular mechanisms that plants utilize to manage resource acquisition and survive environmental stress. Researchers contrast the hydraulic efficiency and mechanical support strategies of various life-forms, such as woody climbers, trees, and herbs, noting how xylem structure and vessel diameter adapt to drought or habitat. A significant portion of the text explores chemical signaling, specifically how the hormones abscisic acid (ABA) and ethylene coordinate stomatal regulation, seed vigor, and growth during water or salt stress. The collection also explains the genetic control of flowering and sene ...
