Calcium Signaling in Plant Programmed Cell Death

Abstract: Programmed cell death (PCD) is a process intended for the maintenance of cellular homeostasis by eliminating old, damaged, or unwanted cells. In plants, PCD takes place during developmental processes and in response to biotic and abiotic stresses. In contrast to the field of animal studies, PCD is not well understood in plants. Calcium (Ca2+) is a universal cell signaling entity and regulates numerous physiological activities across all the kingdoms of life. The cytosolic increase in Ca2+ is a prerequisite for… Show more

“…In this study, there was a large number of amyloplasts in the pulp cells of apples with bitter pit undergoing PCD at the same time. Ca 2+ concentration increases in the early stage of post-harvest physiological deterioration of cassava storage roots, thereby causing PCD ( Ren et al, 2021 ).…”

“…Ca 2+ is a universal and indispensable signaling ion used by all eukaryotes. 74–77 In tumor cells, Ca 2+ regulates cellular activities and impact tumor progression including proliferation, metabolism, migration, epithelial–mesenchymal transition (EMT), and apoptosis. 78–82 Emerging studies have demonstrated that Ca 2+ signaling in cancer cells is affected by various mechanical stimuli including cyclic stretch, 83 local membrane traction, 84 fluid shear, 85,86 and compression.…”

“…Furthermore, NO, a negative chemoattractant of pollen tube guidance, together with ROS, a positive regulator of tip growth, were shown to be required for the pollen tube elongation to the right direction [ 19 , 20 ]. These findings, together with multitasked feature of ROS, Ca 2+ , and NO [ 2 , 21 , 22 , 23 , 24 ], suggest that these signaling molecules might govern the reproductive development by regulating various other pathways.…”
