Body building on land: morphological evolution of land plants.
Published 2009“…The life cycle of the land plant body comprises two multicellular stages -- one haploid (gametophyte) and the other diploid (sporophyte). Recent discoveries suggest that the genes controlling diploid development in ancestral green algal zygotes diversified in the land plant lineage where they control the development of the diploid body plan. …”

Plant meiosis: the means to 1N.
Published 2001“…In addition to providing an opportunity for genetic reassortment, it marks the transition from diploid sporophyte to haploid gametophyte. Recent molecular data suggest that, like animals, plants possess a common set of genes (also conserved in eukaryotic microorganisms) responsible for meiotic recombination and chromosome segregation. …”

PXL1 and SERKs act as receptor–coreceptor complexes for the CLE19 peptide to regulate pollen development
Published 2023-06-01“…Abstract Gametophyte development in angiosperms occurs within diploid sporophytic structures and requires coordinated development; e.g., development of the male gametophyte pollen depends on the surrounding sporophytic tissue, the tapetum. …”

Genomic methylation patterns in pre-meiotic gynoecia of wild-type and RdDM mutants of Arabidopsis
Published 2023-03-01“…The gynoecium is the floral reproductive organ from which the ovules develop and generate meiotically derived cells that give rise to the female gametophyte. It is not known whether the gynoecium can condition genomic methylation in the ovule or the developing female gametophyte.MethodsWe performed whole genome bisulfite sequencing to characterize the methylation patterns that prevail in the genomic DNA of pre-meiotic gynoecia of wild-type and three mutants defective in genes of the RNA-directed DNA methylation pathway (RdDM): ARGONAUTE4 (AGO4), ARGONAUTE9 (AGO9), and RNA-DEPENDENT RNA POLYMERASE6 (RDR6). …”
