Programmed cell death (PCD) refers to the death of a cell that is genetically “programmed. Alongside cell division and cell migration, PCD enables the organism to strictly control cell numbers and tissue size as well as to protect itself from unwanted cells that threaten homeostasis. Programmed cell death, specifically apoptosis, a physiological form of cell death was first reported in the nematode C. elegans in 1972. Since this initial discovery, the functional roles of programmed cell death have been intensely scrutinized and observed across kingdoms ranging from animals to plants. Akin to their mammalian counterparts studies have shown that PCD pathways are vital players in the mediation of plant responses to a range of abiotic stresses, including drought. This chapter will provide:

  • i) an overview of PCD and its roles during development and in response to environmental stimuli;

  • ii) comprehensive literature review of PCD with details of execution and regulation of apoptosis - the most understood form of PCD;

  • iii) PCD and factors that induce cell death in plants;

  • iv) physiological basis of manipulation of PCD pathways enhancing tolerance to abiotic stress in plant;

  • v) molecular studies of manipulation of PCD pathways as a mechanism of drought stress tolerance in plants, and;

  • vi) implication and future directions.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
