Endosperm cell death: roles and regulation in angiosperms Open
Double fertilization in angiosperms results in the formation of a second zygote, the fertilized endosperm. Unlike its embryo sibling, the endosperm is a transient structure that eventually undergoes developmentally controlled programmed ce…

From the archives: Boosting rice immunity, phosophoglucose isomerases influencing seed yield, and regulation of mRNA splicing Open
Boosting rice immunity to fight the blast fungusRice blast disease caused by the ascomycete Magnaporthe oryzae represents a worldwide threat to rice culture.To fight it, the plant sets up immune responses that involve the expression of pat…

Fertility loss in senescing Arabidopsis ovules is controlled by the maternal sporophyte via a NAC transcription factor triad Open
Flowers have a species-specific fertile period during which pollination and fertilization have to occur to initiate seed and fruit development. Unpollinated flowers remain receptive for mere hours in some species, and up to several weeks i…

Functional and developmental convergence in the reproductive “nurse cells” of flowering plants Open
The successful sexual reproduction of flowering plants depends upon double fertilisation, during which pollen grains, produced within the male floral organ (the anther) deliver two sperm cells to the ovule, buried deep within the ovary, tr…

A peptide-mediated, multilateral molecular dialogue for the coordination of pollen wall formation Open
Significance Pollen viability depends on a tough external barrier called the pollen wall. Pollen wall components are produced by tapetum cells, which surround developing pollen grains within the anther. Precise coordination of tapetum acti…

KIL1 terminates fertility in maize by controlling silk senescence Open
Plant flowers have a functional life span during which pollination and fertilization occur to ensure seed and fruit development. Once flower senescence is initiated, the potential to set seed or fruit is irrevocably lost. In maize, silk st…

A peptide-mediated, multilateral molecular dialogue for the coordination of pollen wall formation Open
The surface of pollen grains is reinforced by pollen wall components produced non-cell autonomously by tapetum cells that surround developing pollen within the male floral organ, the anther. Here we show that tapetum activity is regulated …

Transcriptomics at Maize Embryo/Endosperm Interfaces Identifies a Transcriptionally Distinct Endosperm Subdomain Adjacent to the Embryo Scutellum Open
Seeds are complex biological systems comprising three genetically distinct tissues nested one inside another (embryo, endosperm, and maternal tissues). However, the complexity of the kernel makes it difficult to understand intercompartment…

A two-way molecular dialogue between embryo and endosperm is required for seed development Open
Filling in the gaps In a plant seed, the embryo lies dormant surrounded by nutritive endosperm while awaiting suitable conditions to germinate. A hydrophobic cuticle around the embryo protects it from catastrophic water loss during the ear…

Be prepared: How do baby plants protect themselves before escaping the seed? Open
A continuous protective cuticle formed around the embryo is a prerequisite for plant survival in dry environment. We show that a molecular dialogue between the embryo and the surrounding nutritive tissue in the seed ensures that the cuticl…

A two-way molecular dialogue between embryo and endosperm required for seed development Open
The plant embryonic cuticle is a hydrophobic barrier deposited de novo by the embryo during seed development. At germination it protects the seedling from water loss and is thus critical for survival. Embryonic cuticle formation is control…

ZHOUPI and KERBEROS Mediate Embryo/Endosperm Separation by Promoting the Formation of an Extracuticular Sheath at the Embryo Surface Open
Arabidopsis thaliana seed development requires the concomitant development of two zygotic compartments, the embryo and the endosperm. Following fertilization, the endosperm expands and the embryo grows invasively through the endosperm, whi…
