Summary
The SHORT INTERNODES/STYLISH (SHI/STY) protein family regulates plant development, including lateral roots and flowering time. This review explores their evolution, structure, functions, and agricultural applications.
Area of Science:
- Plant molecular biology
- Developmental genetics
Background:
- The SHORT INTERNODES/STYLISH (SHI/STY) protein family is crucial for early lateral organ development in plants.
- Research on the SHI/STY family's evolutionary and functional aspects remains limited.
Purpose of the Study:
- To review recent studies on SHI/STY genes, focusing on their evolution, structure, and biological functions.
- To explore the agricultural applications of SHI/STY functions.
- To identify knowledge gaps for future research directions.
Main Methods:
- Literature review of recent studies on SHI/STY genes.
- Analysis of conserved domains (RING-like zinc finger, IGGH) within SHI/STY proteins.
- Discussion of documented biological roles and regulatory pathways.
Main Results:
- SHI/STY proteins possess conserved RING-like zinc finger and IGGH domains.
- SHI/STYs are implicated in lateral root formation, stem elongation, leaf development, and root nodule development.
- These proteins also regulate reproductive organ development, flowering time, and hormone signaling pathways (GA, JA, auxin).
Conclusions:
- The SHI/STY gene family plays diverse roles in plant growth and development.
- Understanding SHI/STY functions offers potential applications in modern agriculture.
- Further research is needed to fully elucidate the complex roles and regulatory mechanisms of SHI/STY proteins.

01:25Cell Signaling in Plants
5.7K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

2.8K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

1.9K
Chloroplasts are triple membrane structures with an outer membrane, an inner membrane, and a thylakoid membrane, each containing distinct metabolite transporters, membrane translocons, and enzymes. Appropriate sorting and translocating these proteins to their correct membrane systems is essential for chloroplast function.
Protein complexes called the translocon of the outer chloroplast membrane or TOC complex, and the translocon of the inner chloroplast membrane or TIC complex mediate the...

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

01:11Protein Transport to the Outer Chloroplast Membrane
2.0K
Chloroplast outer membrane proteins encoded by the nucleus are synthesized in the cytosol. Soon after synthesis, they bind cytosolic factors such as 14-3-3 protein and the Hsp70 chaperones that keep these precursors in an unfolded state until their translocation.
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.

Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...
