Regulation of cytoskeletal dynamics by phospholipase D and phosphatidic acid

Genome-wide analysis and expression profiling of the phospholipase D gene family in Gossypium arboreum

“…It is now known that PLD is a ubiquitous enzyme participating in the regulation of numerous physiological processes, including plant growth, development, and multiple stress responses, such as drought, salinity, nutrient deficiency, freezing, wounding and pathogen infection (Hong et al, 2010;Wang, 2005). The diverse functions of PLD are often carried out through its enzymatic product, PA, which is regarded as a universal lipid signaling molecule (Pleskot et al, 2013;Wang et al, 2006). PLD was identified as an enzyme involved in lipid metabolism and membrane reconstruction as early as in 1940s (Hanahan and Chaikoff, 1947).…”

Capping Protein Modulates Actin Remodeling in Response to Reactive Oxygen Species during Plant Innate Immunity

“…Genetic evidence from various organisms demonstrates that the availability of barbed ends for actin assembly is inversely correlated with cellular CP levels (Kim et al, 2004;Li et al, 2012Li et al, , 2014a. Moreover, CP has been implicated in the crosstalk of signaling events from membrane to actin cytoskeleton via phospholipid binding (Pleskot et al, 2013). Plant CP is unique in the ability to bind the stress signaling phospholipid, phosphatidic acid (PA), which inhibits capping activity and uncaps filament ends in vitro and in vivo (Huang et al, 2006;Li et al, 2012;Pleskot et al, 2013).…”

The pathways for actin remodeling during innate immune signaling are both parallel and convergent, and potentially tissue-specific.…”

Effect of n-butanol and cold pretreatment on the cytoskeleton and the ultrastructure of maize microspores when cultured in vitro

“…choline, ethanolamine or glycerol) and different PA species (Wang et al 2014a). These PA molecule types may have various target enzymes (Wang et al 2014b), regulating diverse functions of cells, such as response to abscisic acid and reactive oxygen species, programmed cell death, membrane trafficking and cytoskeletal dynamics (Hong et al 2010;Pleskot et al 2013). When n-butanol is present, PLD transfers the phosphatidyl group to butanol, instead of -OH group originated from water.…”
