Leaf Senescence

Programmed aging and degradation of leaves, recycling nutrients for plant growth.

Key Functions:

• Redistributes nutrients to developing tissues.
• Regulated by hormones like ethylene.
• Triggers seasonal dormancy.

Interacting Systems & Components:

• ETR (regulates ethylene signaling)
• Hormone Signaling (controls)
• Leaf Morphology (affected)
• Nutrient Uptake (supports)
