Abstract
The study of programmed cell death (PCD) activated in a certain group of cells is complex when analyzed in the whole plant. Plant cell suspension cultures are useful when investigating PCD triggered by environmental and developmental stimuli. Due to their homogeneity and the possibility to synchronize their responses induced by external stimuli, these cultures are used for studying the signaling pathways leading to PCD. The first problem in the analysis of PCD in cell cultures is the quantification of cell viability/death over time. Cultured cells from different plant species may have specific mitotic patterns leading to calli or cell chains mixed to single cell suspensions. For this reason, not all cell cultures allow morphological parameters to be investigated using microscopy analysis, and adapted or ad hoc methods are needed to test cell viability.
Here we report on some accurate methods to establish and propagate cell cultures from different plant species, including crops, as well as to determine cell viability and PCD morphological and genetic markers. In particular, we describe a protocol for extracting nucleic acids required for real-time PCR analysis which has been optimized for those cell cultures that do not allow the use of commercial kits.
