TranscriptomicsSmall RNA profiles of the rice non-pollen male sterile line Wuxiang S reveal miRNAs involved in the fertility transition
Illumina sequencing was employed to examine the expression profiles of rice anther miRNAs from the a non-pollen male sterile line Wuxiang S (WXS), one of photo-thermo sensitive genical male sterile (PTGMS) line rice, during in the fertility transition stage. A total of 493 known miRNAs and 273 novel...

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...

TranscriptomicsGene expression profiling of maize anther and pollen ontogeny
Global gene expression profiles of seven stages representing 29 days of anther development are analyzed using a 44K oligonucleotide array querying ~80% of maize protein-coding genes. Each anther stage expresses ~10,000 constitutive and ~10,000 or more transcripts restricted to one or a few stages. ...

ProteomicsHeat stress induced proteomes in tomato pollen mother cells and microspores
During the reproductive stage, tomatoes require nighttime temperatures below 21°C and daytime temperatures below 32°C for healthy flower development and fruit set. Prolonged exposure to temperatures above the optimal range can cause abnormalities in pollen development, leading to reduced fertility o...

TranscriptomicsTranscription profiling of Arabidopsis microgametogenesis
Aims We aim to use transcriptome analysis to establish on a genome-wide scale the identity and regulatory clusters of genes that specify microgametogenesis from the haploid microspore to mature functional pollen in Arabidopsis. Background Pollen as the haploid male gametophyte plays a vital role in ...

TranscriptomicsMSH7 confers quantitative variation in pollen fertility and boosts grain yield in maize
Fertile pollen is critical for the survival, fitness and dispersal of flowering plants, and directly contributes to crop productivity. Extensive mutational screening studies have been carried out to dissect the genetic regulatory network determining pollen fertility, but we still lack fundamental kn...

TranscriptomicsTranscription profiling of Arabidopsis male-sterile opr3 mutant stamens treated with jasmonate or its precursor, 12-oxophytodienoic acid
In Arabidopsis, jasmonate is required for stamen and pollen maturation. Mutants deficient in jasmonate synthesis, such as opr3, are male-sterile but become fertile when jasmonate is applied to developing flower buds. We have used ATH1 oligonucleotide arrays to follow gene expression in opr3 stamens...

TranscriptomicsIdentification of Rf genes in hexaploid wheat (Triticum aestivum L.) by next generation sequencing of products of Representational Difference Analysis (RDA-seq).
Plants of two non-restorer varieties of hexaploid winter wheat (Astoria, Grana) and two restorers ones (Patres and Primépi) were used to Representational Difference Analysis (cDNA-RDA) to identify effective Rf (fertility restorer) genes. Anthers at the microspore stage were used as testers while ant...
