Modeling the Roles of miRNA164 in Determining the Age-dependent Cell Death in Plant Leaves
Senescence is a genetically controlled developmental process that leads to cell death and limits the life span at the cellular, tissue, organ, and organism levels 1. Leaf senescence and the associated cell death, are evolutionary selected developmental processes to maximize plants fitness by facilitating nutrient recovery and recycling 2. For example, annual plants such as soybean, corn, or rice relocate nutrients from senescing leaves to reproducing seeds through leaf senescence, which ensures optimal production of offspring and better survival of plants in given temporal and spatial niches. It is well known that the timing of leaf senescence is controlled by developmental age under the influence of other internal factors such as phytohormones and reproductive development and external factors including abiotic and biotic stresses 3, 4. Therefore, it is obvious that multiple pathways responding to various endogenous and environmental factors are interconnected to form a highly complex regulatory network whose dynamic operation induces age-dependent leaf senescence by fine-tuning the initiation timing and progression rate.
