TranscriptomicsTranscription profiling of Arabidopsis stigma tissue - pollination study
Microarray experiments were used to build a profile of candidate stigma genes that facilitate early pollination events. Of over 24,000 genes probed, we identified 11,403 genes expressed in stigma tissue, 317 of these that are stigma specific (not expressed in control tissues). To appear in Sexual P...

TranscriptomicsTranscription profiling of rice stigma
In angiosperms, stigma provides initial nutrients and guidance cues for pollen grain germination and tube growth. However, little is known about genes that regulate these processes in rice. Here we generate rice stigma-specific gene expression profiles through comparing genome-wide expression patter...

ProteomicsThe Brassica Mature Pollen and Stigma Proteomes: Preparing to Meet
Successful pollination brings together the mature pollen grain and stigma papilla to initiate an intricate series of molecular processes meant to eventually enable sperm cell delivery for fertilization and reproduction. At maturity, the pollen and stigma cells have acquired proteomes comprising the...

ProteomicsThe Triticale Mature Pollen and Stigma Proteomes – Assembling the Proteins for a Productive Encounter
Triticeae crops are major contributors to global food production and ensuring their capacity to reproduce and generate seeds is critical. However, despite their importance our knowledge of the proteins underlying Triticeae reproduction is severely lacking and this is not only true of pollen and sti...

TranscriptomicsTransciptome time course of Arabidopsis stigma senescence
n Arabidopsis thaliana, the non-pollinated floral stigma degenerates about 3 to 4 days after flower opening. This data set describes the changes in the stigma transcriptome profiles during this senescence process. Three timepoints cover the young (TP1), the mature (TP2), and the senescent (TP3) stig...

GenomicsMicroRNAs in Pyrus stigma tissue and stigma exudates
In many plant species, flower stigma secretions are important in early stages of sexual reproduction. Previous chemical analysis and proteomic characterization of these exudates provided insights into their biological function. Nevertheless, the presence of nucleic acids in the stigma exudates has n...

TranscriptomicsGene expression analysis in stigma during compatible and in-compatible pollination reactions in Lolium perenne
The expression analysis had two goals: (1) look at relative transcription within mature pollen grains (2) compare expression in the stigma during pollination with either compatible or in-compatible pollen. Two pairwise comparisons, (i) unpollinated stigma vs. stigma pollinated with compatible pollen...
