Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
Electrical Synapses01:28

Electrical Synapses

Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...
Seed Structure and Early Development of the Sporophyte02:33

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.
Tight Junctions01:29

Tight Junctions

Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...
Eukaryotic Transcription Inhibitors01:52

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a DNA...

Summary

Rice empty glumes are homologous to lemmas, a finding supported by the ELE gene. This gene regulates empty glume development, and its mutation results in lemma-like structures, clarifying grass floral organ identity.

Area of Science:

  • Plant developmental biology
  • Grass floral organ evolution
  • Molecular genetics

Background:

  • Homology exists between grass (Poaceae) and eudicot reproductive organs.
  • The identity of grass-specific floral organs like glumes, palea, and lemma remains debated.

Purpose of the Study:

  • To provide direct evidence for the homology of rice empty glumes with lemmas.
  • To investigate the genetic regulation of rice empty glume development.

Main Methods:

  • Analysis of mutations in the ELE (elongated empty glume) gene in rice (Oryza sativa).
  • Examination of floral morphology and epidermal features of wild-type and mutant plants.
  • Gene expression analysis of ELE in immature spikelets.

Main Results:

  • Mutations at the ELE locus result in elongated empty glumes with lemma-like morphology and vascularization.
  • The ELE gene is nuclear-localized and specifically expressed in immature empty glumes.
  • Ectopic expression of ELE leads to various floral developmental defects, including lemma-like palea and extra floral organs.

Conclusions:

  • Rice empty glumes are identified as lemmas of sterile florets.
  • The ELE gene acts as a growth regulator, normally restricting empty glume size in wild-type rice.
