MetabolomicsMetabolomic analysis of inhibited pollen tube growth in unilateral crosses of Clematis

This study utilized broad-target metabolomics to analyze the metabolic changes underlying the inhibition of pollen tube growth in Clematis one-way hybrid crosses with low compatibility. It identified differentially accumulated metabolites and elucidated the key metabolic pathways involved in one-...

TranscriptomicsTranscription profiling of Arabidopsis cell-sorted, hydrated pollen grains vs those of flowers, leaves, seedlings and siliques
Upon germination, pollen forms a tube that elongates dramatically through female tissues in order to reach and fertilize ovules. While essential for the life cycle of higher plants, the genetic basis underlying most of the process is not well understood. We used Affymetrix Arabidopsis ATH1 Genome Ar...

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...

TranscriptomicsTranscription profiling of Arabidopsis pollen germination and tube growth
Pollen germination, along with pollen tube growth, is an essential process for the reproduction of flowering plants. The germinating pollen with tip-growth characteristics provides an ideal model system for the study of cell growth and morphogenesis. As an essential step towards a detailed underst...

TranscriptomicsTranscription profiling of Arabidopsis germinating pollen
In sexual reproduction, a proper communication and cooperation between male and female organs and tissue are essential for male and female gametes to unite. In flowering plants, female sporophytic tissues and gametophyte direct a male pollen tube towards an egg apparatus, which consists of an egg ce...

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...

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...

ProteomicsPollen tube proteomics of Solanum lycopersicum and S. pennellii
To identify candidate genes for the pui6.2 and pui12.1 loci, we performed a comparative proteomic analysis of pollen tube proteins from S. lycopersicum Heinz and S. pennellii LA0716.

TranscriptomicsEthylene perception modulates tomato pollen tube growth by altering calcium signaling and cell wall remodeling
In tomato, there are seven ethylene receptors, ETR1, ETR2, ETR3, ETR4, ETR5, ETR6, and ETR7. In our laboratory, we have ETR3, ETR4, and ETR7, loss-of-function single mutants, in this study we compare the pollen tube length of ETR mutant KO with WT and NR (never rip) gain of function mutant. We foun...
