Seedling proteome of Arabidopsis thaliana pux10-3 mutants

ABSTRACT: Lipid droplets (LD) of seedlings lacking PUX10 stay significantly smaller during germination than the LDs of wild type seedlings. The observation that the removal of a LD-associated protein from a plant affects LD morphology has been observed previously {Siloto et al., 2006}{Gidda et al., 2016}. Especially the effect of the knock-out of the major structural LD protein Oleosin1 leading to a strongly increased size of LDs described by Siloto et al. might indicate that the abundance of structural LD proteins influences the LD size. Thus, the influence of the absence of PUX10 on the abundance of these proteins was investigated via a proteomic approach. Here, proteins isolated from homogenized seedlings of different lines (Ws-4 and pux10-3) and different developmental stages (wet seeds, and 1 to 3 days after imbibition (dai)) were subjected to tryptic digest and LC-MS/MS analysis.
