Variants of Cytokinin Receptors


The productivity of a plant can be influenced in various different ways, e.g. by improving plant growth characteristics or by delaying leaf senescence. Cytokinins are a class of plant hormones controlling numerous aspects of plant development throughout the life cycle. <br><br> The present invention relates to two novel gain-of-function variants of the cytokinin receptors AHK2 and AHK3, namely rock2 and rock3 of Arabidopsis which can be used to generate transgenic plants overexpressing one of said new gain-of-function cytokinin receptor variants. <br><br> Compared to wild-type the Arabidopsis rock2 and rock3 mutants show:<ul> <li>Enhanced vegetative growth </li> <li>>75% increase of fresh weigth at 18 days after germination </li>

<li>43% increase of rosette size </li></ul><br> Shoot height, fresh weight of stems, the number of siliques on the main stem and the number of siliques per plant were all increased between 18% and 31% in Arabidopsis rock2 mutants compared to wild-type. Transgenic rock2- or rock3- overexpressing Arabidopsis plants show increased shoot height, a higher number of siliques per plant, thicker stems and bigger flowers. <br><br> <strong>Benefits</strong> <ul> <li>Novel gain-of-function variants of the cytokinin receptors AHK2 and AHK3</li> <li>Generation of transgenic rock2 and/or rock3 plants with improved productivity and/or growth characteristics</li> </ul> <p><strong>IP Rights</strong><br> European patent granted in BE, DE, CH, ES, FR, GB, NL, SE (03/2012)<br> Patent applications pending in AU, BR; AR; CA; IN, MX, CN, US <br> Priority 06/2009 <br> <br> <strong>Origin</strong><br> The technology was developed at the Free University of Berlin (Germany).</p>

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
