TranscriptomicsMicroRNA Profiles and Their Control of Male Gametophyte Development in Rice
Plant microRNAs (miRNAs) act as negative regulators of gene expression by slicing target transcripts or inhibiting the translation, and a number of miRNAs play important roles in development. In order to investigate the potential function of miRNAs during male gametogenesis in rice, we obtained both...

TranscriptomicsGene Expression Profiling during Male Gametophyte Development in Rice
To investigate the potential function of miRNAs during male gametogenesis in rice, we first obtained gene expression profiles by using Affymetrix microarray technologies. In genome-scale, we found a common characteristic shared by rice and Arabidopsis, which vast of genes are down regulated from Pb ...

TranscriptomicsAnalysis of anther transcriptomes to identify genes contributing to meiosis and male gametophyte development in rice
Background – In flowering plants, the anther is the site of male gametophyte development. Two major events in the development of the male germline are meiosis and the asymmetric division in the male gametophyte that gives rise to the vegetative and generative cells, and the following mitotic divisio...

ProteomicsRegulatory dynamics of gene expression in the developing male gametophyte of Arabidopsis
Sexual reproduction in angiosperms requires the production and delivery of two male gametes by a three-celled haploid male gametophyte. This demands synchronised gene expression in a short developmental window to ensure double fertilization and seed set. While transcriptomic changes in developing po...

MetabolomicsIdentification and Molecular analysis of the Y-specific CpMp gene controlling long male peduncles in papaya

Papaya is a fruit crop possessing XY sex chromosomes. The development of long 

male peduncles (Mp) is pivotal for the evolutionary transition from gynodioecy to 

dioecy. The gene, CpMp, which controls peduncle length, is one of the four genes 

contributing to...

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 ...

TranscriptomicsProfiling of small RNA populations in tricellular pollen of rice
To investigate the potential function of miRNAs during male gametogenesis in rice, 13-40 nt RNA were extrected from tricellular pollen (TCP) for high-throughput sequencing. We identified 104 unique miRNAs from TCP library, 57 of which are novel derived from 39 pre-miRNAs. This subseries contain one ...

TranscriptomicsGene expression in mature pollen and sperm cells versus young seedling as a vegetative sporophyte reference control
Sperm cells represent the male partner that fuses with the egg cell during fertilization in all multi-cellular eukaryotic organisms, and, in flowering plants, is a founder of both embryo and nutritive endosperm. We examined the transcriptome of Oryza sativa ssp. japonica using the Affymetrix 57K ri...

TranscriptomicsSeparated Transcriptomes of Male Gametophyte and Tapetum in Rice
In flowering plants, the male gametophyte, the pollen, develops in the anther. Complex patterns of gene expression in both the gametophytic and sporophytic tissues of the anther regulate this process. The gene expression profiles of the microspore/pollen and the sporophytic tapetum are of particular...
