This Collection supports and amplifies research related to SDG 2 - Zero hunger
Plant reproductive development, spanning flowering, pollination, fertilization, and seed formation, is orchestrated through the integration of genetic, epigenetic, hormonal, and environmental cues. Understanding how these multifaceted inputs are dynamically regulated and coordinated to ensure reproductive success is important for biodiversity and agricultural productivity. While significant progress has been made, recent technological advances, such as gene-editing, single-cell omics, super-resolution imaging, and phylogenomics, are enabling deeper understanding of reproductive processes across spatial, temporal, and evolutionary scales. This collection invites studies encompassing diverse aspects of plant reproductive development including (not limited to) cellular and molecular regulation of developmental stages, signaling cascades in response to intrinsic and extrinsic cues, and evolutionary principles shaping reproductive diversity.
Nature Communications and Communications Biology will consider original Articles, Reviews and Perspectives. Scientific Reports will consider original Articles.
Epigenetic modifications are crucial for plant development. Here, the authors find an epigenetically mediated double negative cascade for pollen formation and anther dehiscence, offering new insights into epigenetic regulation of anther development.
H3K9me2, a canonical heterochromatin epigenetic mark, is less in the companion vegetative cell than in sperm cells. Li et al. uncover that ARID1, a pollen-specific transcription factor, reinforces H3K9me2 maintenance in sperm cells.
In flowering plants, hermaphroditism is widespread. Here the authors identified a transposon insertion that triggers plant sexual transition. This study highlights the role of transposons in plant adaptation and evolution.
In Arabidopsis, the pollen vegetative cell is regarded as a source of mobile siRNAs that guide male germline reprogramming. This study demonstrates that siRNA triggers of triploid seed lethality originate in germline companion cells after meiosis.
Population genomic and epigenomic study in a facultatively asexual plant indicates that natural selection can act on the controls of asexual reproduction during range expansion, which in turn might reduce genetic and epigenetic diversity in the population.
The phosphorylated pathway of serine biosynthesis plays a critical role in growth and development, and affects the tricarboxylic acid cycle, the amino acid and nucleotide metabolism and lipid metabolism in Marchantia polymorpha.
A study on a soybean DNA demethylase reveals that seed size is negatively regulated by GmDMEa, which is closely linked to methylation on transposon elements.
