TranscriptomicsTranscription profiling of Arabidopsis pollen and semi in vivo- and in vitro-grown pollen tubes.
Pollen tubes extend through pistil tissues and are guided to ovules where they release sperm for fertilization. Although pollen tubes can germinate and elongate in a synthetic medium, their trajectory is random and their growth rates are slower compared to growth in pistil tissues. Furthermore, inte...

ProteomicsTobacco pollen tube-secretome following penetration through the pistil
As in animals, cell-cell communication plays pivotal role in male-female recognition during plant sexual reproduction. Prelaid peptides secreted from the female reproductive tissues guide pollen tubes towards ovules for fertilization. However, the elaborate mechanisms for this dialogue have remained...

TranscriptomicsTranscript Profiling of Maize Embryo Sac and Preliminary Identification of Genes Involved in Embryo Sac-Pollen Tube Interactions
In this study, we identified the genes specifically/preferentially expressed in maize embryo sac and genes differentially expressed before and after pollination in maize embryo sac via RNA-seq. In total, more than 30% of them are unknown functions and more than 80% of which are first reported in mai...

ProteomicsA mitogen-activated protein kinase limits the apical formation of phosphatidylinositol 4,5-bisphosphate during polarized cell expansion of pollen tubes
Mitogen activated protein kinases (MAPKs) and phosphoinositides contribute to establishment and maintenance of polarity in eukaryotic cells. However, interactions between these important signaling pathways are largely unclear. Pollen tubes are an important model for the study of polarized cell expan...

ProteomicsRice pollen plasma membrane iTRAQ
The coordination of pollen tube (PT) growth, guidance and timely growth arrest and rupture mediated by PT-pistil interaction is crucial for the PT to transport sperm cells into ovules for double fertilization. The plasma membrane (PM) represents an important interface for cell–cell interaction, and ...

TranscriptomicsPollen tube emergence is mediated by ovary-expressed ALCATRAZ in cucumber
Cucumber is an important vegetable crop worldwide, which is mainly propagated by seed. The successful occurrence of double fertilization is the premise of seed production in angiosperms. Cucumber ALC homolog (CsALC) displayed a novel and positive function in pollen tube emergence process, and regula...
