Project description:The number of known proteins associated with plant lipid droplets (LDs) is small compared to other organelles. Many questions of LD biosynthesis and degradation remain open, also due to lack of candidate LD proteins whose characterization could help to elucidate their function in those processes. We performed a proteomic screen on LDs isolated from Nicotiana tabacum pollen tubes. Proteins that were highly enriched in the LD fraction compared to the total or cytosolic fraction where verified for LD localization via transient expression in tobacco pollen tubes. We also compared the isoforms of typical LD proteins found in the pollen tubes on a qualitative level to the isoforms found in tobacco seeds.
Project description:Transcriptome profiling of three developmental stages of immature male gametophyte intobacco (Nicotiana tabacum) Total RNA isolated from tobacco microspores and early and late bicellular pollen was hybridised on Agilent Tobacco Gene Expression Microarray 4x44K in two biological replicates per sample
