"We have generated a draft DNA sequence and initial assembly of the date palm using the most advanced technology," says Joel Malek, director of the Genomics Laboratory at WCMC-Q. Genetic information about the date palm is extremely valuable to researchers who are working to improve fruit yield and quality and to better understand susceptibility and resistance to disease.
"This is an important step for our biomedical research program," says Khaled Machaca, Ph.D., professor of physiology and biophysics and associate dean for basic science research. "It clearly demonstrates the feasibility and success of the most advanced genomics technologies in Qatar and represents a milestone towards establishing Qatar and Weill Cornell as a regional research center of excellence. In addition, this achievement by the WCMC-Q research team holds great promise for the application of the genomics technology to a better understanding of biomedical problems."
The date palm sequencing work was a proof of concept study, according to Malek, who established the genomics laboratory last year. The goal was to establish and validate the capabilities of the core lab for large-scale genomics projects. The lab is an integral part of a large biomedical research program launched last year by WCMC-Q with support from the Qatar Foundation that aims to make Qatar a hub for research in the Middle East.
To produce the draft map, the WCMC-Q researchers used a next generation sequencing approach, which Malek says offers data quality between that of the expressed sequence tag (EST) method and the traditional whole-genome mapping method. "We were able to develop a relatively unbiased view of the gene space of the entire date palm plant at a fraction of the cost and in a much shorter period of time. Using this approach, which takes advantage of the lower repetitive DNA in the date palm gene regions, we have increased the publicly available knowledge of the date palm gene by about 1000 fold."
Malek and his research assistants obtained the DNA from leaves of the date palm provided by the Qatar Plant Tissue Culture Lab in the Department of Agriculture and Water Research (Qatar Ministry of Municipal Affairs and Agriculture).
Date palm trees play a significant role in agriculture throughout the Middle East, Northern Africa and Pakistan. The fruit is a major source of nutrition in those areas, and the tree itself plays an important role in the development of sustainable agriculture in many drought and saline-affected regions of the world. References in the Qur'an have kept alive the use of dates for medicinal purposes over the centuries.
Malek says he and his colleagues will continue to improve the draft sequence and publish their data. Meanwhile, they are making the information available to scientists and researchers around the world.

Established in partnership with Qatar Foundation, WCMC-Q is part of the Weill Medical College of Cornell University, the first American institution to offer its M.D. degree overseas. WCMC-Q offers a complete and integrated educational program, comprising the two-year Pre-medical Program, followed by the four-year Medical Program, with teaching by Cornell faculty. There are separate admission processes for each Program, guided by the standards of admission in use at Cornell University in Ithaca, and its Medical College in New York City.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
