Pollen grains represent the highly reduced haploid male gametophyte generation in
flowering plants, consisting of just two or three cells when released from the anthers. Their …

During angiosperm male gametophyte development, the male germline is segregated by an
asymmetric cell division of the haploid microspore. This review encompasses recent …

In flowering plants, the two sperm cells are embedded within the cytoplasm of the growing
pollen tube and as such are passively transported to the embryo sac, wherein double …

Flowering of many plant species depends on interactions between basic leucine zipper
(bZIP) transcription factors and systemically transported florigen proteins. Members of the …

Flowering plants have evolved a unique reproductive process called double fertilization,
whereby two dimorphic female gametes are fertilized by two immotile sperm cells conveyed …

Parental genomic imprinting causes preferential expression of one of the two parental
alleles. In mammals, differential sex-dependent deposition of silencing DNA methylation …

The unique double fertilisation mechanism in flowering plants depends upon a pair of
functional sperm cells. During male gametogenesis, each haploid microspore undergoes an …

In flowering plants, fertilization is unique because it involves two pairs of male and female
gametes, a process known as double fertilization. Here, we provide an overview of the field …

Natural cis-antisense siRNAs (cis-nat-siRNAs) are a recently characterized class of small
regulatory RNAs that are widespread in eukaryotes. Despite their abundance, the …

Production of maternal haploids via a male inducer can greatly accelerate maize breeding
and is an interesting biological phenomenon in double fertilization. However, the …
