The incredible vulnerability that reproduction poses for plant species in a warming world

New Phytologist, Volume 251, Issue 6, Page 3111-3118, September 2026.
Generalized plant responses to heat stress across whole‐plant and reproductive scales. Summary Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival ...

Genome-Wide Analysis of DNA Methylation During Ovule Development of Female-Sterile Rice fsv1

G3: Genes, Genomes, Genetics, 2017
The regulation of female fertility is an important field of rice sexual reproduction research. DNA methylation is an essential epigenetic modification that dynamically regulates gene expression during development processes.

The richness, frequency and relatedness components of mate diversity and mate portfolios

New Phytologist, Volume 251, Issue 6, Page 3703-3713, September 2026.
The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.

Female gametophyte development and embryogenesis in Taxus baccata L.

Acta Societatis Botanicorum Poloniae, 2014
Crassinucellate ovules are initiated in Taxus, directly from the shoot apex. The rudimentary pollen chamber is formed in the nucellus. A linear tetrad of megaspores with a functional chalazal megaspore is formed.

Arabidopsis EMB2788/Npa1L1 is critical for pre‐rRNA processing, ribosome biogenesis, and embryo development

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Ribosome assembly, a fundamental process for cellular functions, requires the precise processing of precursor rRNA (pre‐rRNA) into mature rRNAs, a transformation guided by ribosome biogenesis factors (RBFs). While this process is well characterized in yeast and mammals, the roles of RBFs in pre‐rRNA processing in plants remain poorly understood.

Arabidopsis female gametophyte gene expression map reveals similarities between plant and animal gametes [PDF]

, 2010
The development of multicellular organisms is controlled by differential gene expression whereby cells adopt distinct fates. A spatially resolved view of gene expression allows the elucidation of transcriptional networks that are linked to cellular ...

Genomics is modifying our concepts of evolution in homosporous and heterosporous vascular plants

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Across the tree of life, and particularly within land plants, there is a wide diversity and disparity of genome structure. The most well‐studied are angiosperms, comprising mostly small and dynamic genomes, with a history of ancient whole genome duplications.

Cloning and characterization of a female gametophyte-specific gene in Gracilaria lemaneiformis (Gracilariales, Rhodophyte)

, 2011
In this study, forward and reverse suppression subtractive hybridization (SSH) libraries were constructed between female and male gametophyte of Gracilaria lemaneiformis to isolate genes differentially expressed between gametophytes.
