Description
Regulation of fertilization (GO:0080154) is a biological process that modulates the rate, frequency or extent of fertilization, the union of gametes of opposite sexes to form a zygote. This process is fundamental to sexual reproduction and has broad implications in agriculture, ecology, and developmental biology. In plants, fertilization is not only a reproductive event but also a developmental trigger that influences nitrogen assimilation and use efficiency. Recent studies have shown that fertilization controls tiller numbers via transcriptional regulation of MAX1-like genes in rice, linking fertilization to shoot architecture. Moreover, fertilization practices can alter rhizosphere interactions through nitric oxide signaling, affecting beneficial microbes. Understanding the regulation of fertilization is therefore essential for optimizing crop yield, quality, and sustainable agriculture. The process also intersects with environmental health, as fertilization can modify the persistence and enantioselectivity of agrochemicals in soil. This article synthesizes current knowledge on the mechanisms, genes, and research methods for studying GO:0080154, providing a resource for researchers and AI-driven discovery.

What Happens During regulation of fertilization?
Gamete recognition and fusion
In simple terms: Sperm and egg find each other and merge.
Fertilization begins with gamete recognition and fusion, leading to karyogamy and plasmogamy. Regulation of this step ensures species-specificity and successful zygote formation. In Arabidopsis, sperm nuclear morphology can be traced to evaluate fertilization state, highlighting the importance of nuclear events.
Transcriptional control of fertilization-related genes
In simple terms: Genes are switched on or off to control fertilization outcomes.
Fertilization controls tiller numbers via transcriptional regulation of a MAX1-like gene in rice, demonstrating that fertilization signals can directly alter gene expression to shape plant architecture. This transcriptional regulation is a key mechanism modulating the extent of fertilization effects.
Hormonal and signaling modulation
In simple terms: Hormones and signals adjust how fertilization affects growth.
Nitrogen fertilization modulates beneficial rhizosphere interactions through signaling effect of nitric oxide, showing that fertilization regulation involves hormonal and gasotransmitter pathways. Additionally, fertilization application strategies improve yield by regulating phytohormones in rice cultivars.
Metabolic and quality effects
In simple terms: Fertilization changes the chemical makeup and quality of plants.
Transcriptomic analysis reveals effects of fertilization towards growth and quality of Fritillariae thunbergii bulbus, indicating that regulation of fertilization impacts metabolic pathways and secondary metabolite production.
Environmental persistence and soil health
In simple terms: Fertilization can change how chemicals behave in soil.
Fertilization can modify the enantioselective persistence of penthiopyrad in relation to co-influence on soil ecological health, demonstrating that regulation of fertilization extends to environmental fate of agrochemicals.

How Is regulation of fertilization Regulated?
Regulation of fertilization is modulated by nitrogen availability, phytohormones, and signaling molecules such as nitric oxide. Nitrogen fertilization affects nitrogen assimilation and use efficiency, which in turn influences fertilization outcomes. Transcriptional regulation of MAX1-like genes by fertilization controls tiller numbers, linking fertilization to strigolactone signaling. Nitric oxide signaling mediates beneficial rhizosphere interactions under nitrogen fertilization. Phytohormone pathways, including gibberellins, auxins, cytokinins, and abscisic acid, are regulated by fertilization strategies to improve yield. Additionally, fertilization can modify the enantioselective persistence of agrochemicals, indicating that environmental factors also regulate the downstream effects of fertilization.
