The term apomixis encompasses a suite of processes whereby seeds form asexually in
plants. In contrast to sexual reproduction, seedlings arising from apomixis retain the …

In a previous review of male gametophyte development (McCormick, 1993), it was noted that
the two areas posed by Mascarenhas (1975) as fruitful areas for future research were the …

Somatic embryogenesis is defined as a process in which a bipolar structure, resembling a
zygotic embryo, develops from a non-zygotic cell without vascular connection with the …

In the ovules of most sexual flowering plants female gametogenesis is initiated from a single
surviving gametic cell, the functional megaspore, formed after meiosis of the somatically …

The plant life cycle involves an alternation of generations between sporophyte and
gametophyte. Currently, the genes and pathways involved in gametophytic development …

The potential of genetically modified (GM) crops to transfer foreign genes through pollen to
related plant species has been cited as an environmental concern. Until more is known …

Plants and filamentous fungi share with mammals enzymes responsible for DNA
methylation. In these organisms, DNA methylation is associated with gene silencing and …

Reproduction in angiosperms depends on communication processes of the male
gametophyte (pollen) with the female floral organs (pistil, transmitting tissue) and the female …

Seed development in angiosperms initiates after double fertilization, leading to the formation
of a diploid embryo and a triploid endosperm. The active repression of precocious initiation …

Centromeric H3-like histones, which replace histone H3 in the centromeric chromatin of
animals and fungi, have not been reported in plants. We identified a histone H3 variant from …
