Mechanically-gated Ion Channels01:12

Mechanically-gated Ion Channels

Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

ATP Driven Pumps I: An Overview01:27

ATP Driven Pumps I: An Overview

ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and are...
Microtubule Instability02:17

Microtubule Instability

Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...
Microtubule Formation01:23

Microtubule Formation

Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation of...
Microtubule Associated Motor Proteins01:32

Microtubule Associated Motor Proteins

Eukaryotic cells have different motor proteins for transporting various cargo within the cell. These motor proteins differ based on the filament they associate with, the direction they move within the cell, and the type of cargo they transport. Motor proteins that associate with microtubules are known as microtubule-associated motor proteins. There are two families of microtubule-associated motor proteins —Kinesins and Dyneins. Both these proteins assist in the transport of cellular cargos...

Area of Science:

  • Plant Molecular Biology
  • Genetics and Evolution
  • Gene Expression Regulation

Background:

  • Introns in plant tubulin genes are valuable for studying gene expression and genetic relationships.
  • Intron Mediated Enhancement (IME) and Intron Length Polymorphism (ILP) are key areas of investigation.

Purpose of the Study:

  • To investigate the role of 5'UTR introns in rice beta-tubulin genes for IME.
  • To assess the utility of amplifying coding sequence introns for ILP analysis in bean varieties.

Main Methods:

  • Generating transgenic rice plants to study IME.
  • Designing degenerate oligonucleotide primers for intron amplification.
  • Analyzing Intron Length Polymorphism (ILP) across different bean varieties.

Main Results:

  • The intron within the 5'UTR of rice beta-tubulin genes was shown to sustain IME in transgenic rice.
  • Degenerate oligonucleotide mixtures successfully amplified introns to detect ILPs in bean varieties.

Conclusions:

  • Plant tubulin gene introns are effective molecular tools for both IME studies in rice and ILP analysis in beans.
  • This research highlights the conserved utility of tubulin introns across different plant species for genetic and evolutionary studies.
