Special Issue: Senescence and Programmed Cell Death

Special Issue Editorial

Review Paper

The focus of this review concerns chromatin condensation and histone modifications associated with a major transcriptional switch occurring during the process of plant programmed cell death in response to various stimuli.

Phytoglobins act as cellular binary switches regulating metabolism, hormonal responses, and cell fate to affect growth and development and plant responses to the environment.

A review of recent findings on the morphology of senescing petal cells and the regulatory mechanisms of programmed cell death by transcription factors in ethylene-dependent and -independent petal senescence.

Research Paper

Pathway analysis suggests that identified temporal and spatial transcriptomic changes associated with senescence of the short-lived hibiscus flower are regulated by light/circadian clock-, aquaporin-, cell wall-, and calcium-related gene families.
