Project description:Here We revealed the complex mechanism of viviparity in water lily. The transcriptomic signatures identified in this pathway are important basis for future breeding and research of viviparity in water lily and other plant species.

Project description: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). Keywords: Comparative hybridization

Project description: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, and (ii) unpollinated stigma vs stigma pollinated with incompatible pollen. The genotype where stigma samples were harvested from is F1-30, and this is also the pollen source during an incompatible pollination reaction. The compatible pollen source is the variety Foxtrot (heterogeneous populations).

Project description: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 primary molecular effectors required upon their meeting. In Brassica species, knowledge of the roles and global composition of these proteomes is largely lacking. To address this gap, gel-free shotgun proteomics was performed on the mature pollen and stigma of Brassica carinata, a representative of the Brassica family and its many crop species (e.g. B. napus, B. oleracea, B. rapa), which holds considerable potential as a bio-industrial crop. 5608 and 7703 B. carinata mature pollen and stigma proteins were identified, respectively. The pollen and stigma proteomes were found to reflect not only their many common functional and developmental objectives, but also important differences underlying their cellular specialization. Isobaric tag for relative and absolute quantification (iTRAQ) was exploited in the first analysis of a developing Brassicaceae stigma, and uncovered 251 B. carinata proteins that were differentially abundant during stigma maturation, providing insight into proteins involved in the initial phases of pollination.

Project description: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 patterns of hand dissected unpollinated stigma at anthesis with seven tissues including seedling shoot, seedling root, mature anther, ovary at anthesis, seeds of five days after pollination, 10-day-old embryo, 10-day-old endosperm as well as suspension cultured cells by using 57K Affymetrix rice whole genome array. In total, we identified 665 probe sets (550 genes) to be expressed specifically or predominantly in the stigma papillar cells of rice. Real-Time quantitative RT-PCR analysis of 34 selected genes confirmed their stigma-specific expression. The expression of five selected genes was further validated by RNA in situ hybridization. Gene annotation shows that several auxin-signaling components, transporters and stress-related genes are significantly overrepresented in the rice stigma gene set. We also found that genes involved in cell wall metabolism and cellular communication appear to be conserved in the stigma between rice and Arabidopsis. Our results indicate that the stigmas appear to have conserved and novel molecular functions between rice and Arabidopsis.

Experiment Overall Design: Expression profiles of stigma, ovary and seedling tissues were studied and contrasted. Four samples each of seedling and ovary were used; and three stigma samples.
