Poles Apart: Monosporic, Bisporic, and Tetrasporic Embryo Sacs Revisited

Frontiers in Ecology and Evolution, 2020
Bisporic embryo sacs contain nuclei derived from two members of a megaspore tetrad whereas tetrasporic embryo sacs contain nuclei derived from all four members of a tetrad.

Comprehensive analysis of tobacco pollen transcriptome unveils common pathways in polar cell expansion and underlying heterochronic shift during spermatogenesis

BMC Plant Biology, 2012
Background Many flowering plants produce bicellular pollen. The two cells of the pollen grain are destined for separate fates in the male gametophyte, which provides a unique opportunity to study genetic interactions that govern guided single-cell polar ...

Female gametophyte and pollen tube of Epilobium palustre L.

Acta Societatis Botanicorum Poloniae, 2015
The monosporic, tetranucleate embryo sac of Epilobium palustre (Onagraceae) develops from the micropylar megaspore in a linear tetrad. In mononucleate embryo sacs a peculiar chromatic structure associated with a nucleolus appears in the nucleus.

Temperature Modulates Sex-Biased Gene Expression in the Gametophytes of the Kelp Saccharina latissima

Frontiers in Marine Science, 2019
Saccharina latissima is an economically and ecologically relevant kelp species in Europe and North America. In kelps, the sexuality is expressed during the haploid life stage and the microscopic gametophytes exhibit significant sexual dimorphism.

From the MMC Specification to Endosperm Cellularization in Arabidopsis: A Developmental-Handover Framework for Seed Initiation

Plants
Seed initiation in Arabidopsis depends on regulatory transitions that begin before fertilization, yet these events are often treated as separate developmental episodes rather than as a connected sequence.
