“…The obtained results suggest that the degradation of DNA could be due to execution of PCD in lupine embryo axes in relation to salinity. Degradation of nuclear DNA as a symptom of PCD was observed under saline condition in Thellungiella halophila suspension-cultured cells (Wang et al 2010), tobacco protoplasts (Lin et al 2006), Arabidopsis thaliana primary roots (Huh et al 2002), and in rice roots (Chen et al 2009). Other results suggesting the occurrence of PCD during salinity stress in lupine embryo axes come from ultrastructure observation using transmission electron microscope.…”

“…Stress caused by salinity may also lead to PCD induction. Symptoms of PCD under the influence of salinity were observed and reported in unicellular algae Micrasterias denticulata (Affenzeller et al 2009), tobacco protoplasts (Lin et al 2006), the cell suspension of Thellungiella halophila (Wang et al 2010), the roots of Arabidopsis thaliana (Huh et al 2002), the root tips of rice Oryza sativa (Chen et al 2009) and in the cells of mesophilic tobacco leaf Nicotiana tabacum (Andronis and Roubelakis-Angelakis 2010).…”

Embryonic root is the primary site of salinity perception in germinating seeds. To understand better the NaCl stress response of lupine embryo axes, ultrastructural approach combined with analysis of DNA degradation was used. In this study lupine embryo axes were cultured in vitro on the medium supplemented with two salt concentrations 250 and 500 mM to differ the reaction. To assess the rate of DNA damage, alkaline electrophoresis of isolated nuclei and DNA fragmentation analysis were performed. Results of these studies suggest programmed cell death induction under salinity stress. Moreover, ultrastructure observations revealed other characteristic features of programmed cell death like endoplasmic reticulum reorganization, increased level of vacuolization, chromatin condensation and starch grains degradation. Our comparative analysis of ultrastructure changes and DNA fragmentation speak in favour of programmed cell death in lupine (Lupinus luteus L. 'Mister') embryo axes treated for 12 h with 250 and 500 mM NaCl.

“…Regarding ePCD, one of the most studied PCD processes occurs during the hypersensitive response (HR), a localized plant response upon pathogen recognition (Coll et al, 2011;Wu et al, 2014). Also abiotic stresses such as heat, UV radiation, or salt stress can lead to cell death displaying certain hallmarks of PCD (Chen et al, 2009;Qi et al, 2011;Nawkar et al, 2013;Petrov et al, 2015).…”

The analysis of the rice salt proteome by two-dimensional IEF/SDS-PAGE revealed that four mitochondrial proteins, glycoside hydrolase, mitochondrial heat shock protein 70, 20S proteasome subunit, and Cu/Zn-SOD, were up-regulated during PCD induction (Chen et al 2009). …”
