Explore the intricate mechanisms of two-component signaling systems in plants through this 28-minute lecture that examines how these regulatory pathways control ethylene responses, photomorphogenic processes, and circadian rhythms. Delve into hybrid two-component systems (TCS) and their role in ethylene signaling cascades, understanding how plants detect and respond to this important gaseous hormone. Learn about the specialized functions of pseudo kinases and pseudo response regulators, which act as modified components that fine-tune signaling specificity and timing. Investigate how plants utilize two-component signaling to regulate their day-night cycles, coordinating physiological processes with environmental light-dark transitions. Discover the molecular mechanisms underlying photomorphogenic responses, including how plants adjust their growth and development patterns in response to light quality, quantity, and duration through these sophisticated signaling networks.
